salience and lucid dreaming
If vitamin B6 is indeed an efficient promoter of dream salience, it may have a role as a supplement in the induction of lucid dreams. Dream salience describes a combination of psychological conditions that facilitate dream recall. Such conditions are also conducive to lucid dreaming.
Why is this role of vitamin B6 potentially important?
Lucid dreaming is much more than a mental exercise in which hardcore oneiranouts like to dabble. It is a very real phenomenon, the potential applications of which are almost limitless.
In the area of dream research, lucid dreaming would be an all-powerful tool. It could also be used for the treatment of nightmares, to great effect. Rehearsing and practicing skills in a lucid dream environment would also be a option. Last, but certainly not least, lucid dreaming would open up infinite possibilities in regards to entertainment, recreation, and creative problem-solving.
Lucid dreaming is most definitely a vertical worthy of a lot of scientific attention. Efforts in this regard are severely limited by the lack of reliable lucid dream induction techniques. Vitamin B6 could prove to be an aiding element in such a technique.
Vitamin B6 as an alternative to sedative drugs
Above and beyond dream research, vitamin B6 might provide a healthier alternative to sedation.
A 2017 study done in Italy confirmed the possible usefulness of vitamin B6 as a companion solution for melatonin treatment, in the induction of spontaneous sleep in toddlers/children.
The said study focused on ABR, an auditory response test performed on children under the age of 4-5. Such young children are often uncooperative. This means that medical staff is often forced to resort to sedation.
According to the findings of the study, melatonin worked well for the spontaneous induction of sleep in such children – as expected. Furthermore, researchers have found that adding tryptophan and vitamin B6 to melatonin resulted in even better sedation and testing conditions.
The use of such a solution could generally save costs as well as address parental anxiety to some degree. The study concluded that B6 was certainly an avenue worth exploring in this regard.
Vitamin B6 and nightmares
The relationship between vitamin B6 and nightmares is an interesting one. Because it promotes dreaming and supposedly enhances the vividness and color of dreams, vitamin B6 may be considered a promoter of nightmares. After all, nightmares are dreams too. They just stem from different psychological states than their more amiable peers.
On the other hand, as mentioned, vitamin B6 also promotes lucid dreaming. Lucid dreaming is a very promising avenue for the treatment of nightmares, so therein lies the vitamin B6 contradiction.
Based solely on anecdotal reports, we can however conclude that taking vitamin B6 before sleep might bring about nightmares later in the night.
Vitamin B6 and out-of-body experiences
Out-of-body experiences (OBEs) are altered states of consciousness, not unlike lucid dreaming. Since vitamin B6 promotes a sort of psychological condition conducive to lucid dreaming, it is safe to surmise that it also promotes OBEs, such as astral projection.
Obviously, scientific evidence is scant in this regard at best. That said, several Astral Projection portals have listed B6 as an essential supplement, together with galantamine, Huperzine A, melatonin, and choline.
If you are an AP enthusiast and you are not afraid of nightmares, by all means, make sure that your vitamin B6 levels are sufficiently high when attempting to slip into such a state.
Remember that you may not gain a noticeable "boost" out of B6, if you are already sufficiently supplemented with it, but you need it nonetheless.
Start off a smaller dose, like 100mg. Gradually work your way up to 250 mg, but do not exceed it. You can actually overdose on this vitamin.
Vitamin B6 sources
How can you make sure that you do indeed get a sufficient dose of vitamin B6? When it comes to dream enhancement/potentiating, supplements are obviously your best bet.
Other than that, you should be aware that vitamin B6 is an essential nutrient, needed for the synthesis of various neurotransmitters.
It will elevate mood, improve sleep, prevent panic attacks, and it may even have a role in the prevention of Parkinson's disease. Proper dietary intakes of the vitamin are therefore essential.
Which foods contain higher levels of vitamin B6?
The richest sources of vitamin B6 are organ meats, such as liver, heart etc. Fish, poultry, and pork can all be included in this category. Unfortunately, these foods as well as eggs come with an unwanted "baggage," including saturated fats and cholesterol.
Then we have wholegrain cereals and bread, various vegetables and fruits, potatoes, soybeans, peanuts etc. As far as vegetables go, dark leafy veggies, such as spinach, kai lan, and broccoli are your best B6 sources. Fruits-wise, avocados and bananas are your best choice in this regard.
If your diet is a fairly balanced one, you really do not need to bend over backwards to satisfy your normal daily B6 needs.
Adult males need about 1.4 mg each day, while females need 1.2 mg. Anything above that can be jotted down as "supplementation."
You can see that the doses recommended for dream enhancement are much higher than that (from 50 mg to 250 mg).
Vitamin B6 side effects
While vitamin B6 is indeed an essential vitamin, it is possible to overdose on it. A daily dose of 200 mg, taken for an extended period of time (months on end), can lead to peripheral neuropathy. This is a condition affecting the nervous system, which results in loss of feeling in the limbs. Once the B6 overdosing is discontinued, symptoms usually subside. Sometimes however, they can become permanent.
Prolonged administration of high doses of pyridoxine can also lead to other forms of neuropathy. Extreme skin sensitivity, bone pain, numbness, and muscle weakness are all possible.
Other, shorter-term side effects of B6 overdosing are insomnia and cramps.
The bottom line
Vitamin B6 is an essential vitamin, which looks like a promising sleep/dream-modulating supplement.
The doses needed to achieve dream enhancement are rather high, so make sure you do not abuse it in this regard.
The scientific evidence currently backing the anecdotal reports of B6-generated dream enhancement is rather shaky and unconvincing. Science is not entirely certain by which mechanism pyridoxine acts upon dream recall either.
Pick up your B6 supplement right now, and delve into the realm of dreams one step closer to achieving on-demand lucidity.

Ethiopia launching national youth volunteer service program
August 8,2018
The Ethiopian government is launching what is poised to become Prime Minister Abiy Ahmed's flagship program of "trans-boundary volunteers."
With this program, youth volunteers are to serve outside of their respective ethnic-based Federal states, seemingly which is why it is named "trans-boundary", in the country.
1000 graduating students drawn from different parts of Ethiopia are taking part in the program which is commencing today. And volunteer youth are to get credit for their participation when they are looking for employment after graduation.
Prime Minister Abiy Ahmed met with the volunteers today before they are deployed to where they are assigned.
"When you serve the community as volunteers, you also need to learn and acquire knowledge as well," the prime minister told the volunteers. He meant to emphasize that there is knowledge in the community outside of university and other institutions of higher learning.
Apart from providing new graduates with relevant work experience, the motive of the program is to foster what the government describes as "people to people relation" and national feeling.
Ethiopia has a history of mobilizing youth for volunteer work in the community. Soon after the Ethiopian Revolution in 1974, Colonel Mengistu Hailemariam's government embarked on a nationwide illiteracy eradication program by deploying hundreds of thousands of youth in the countryside in different parts of the country to provide basic education. The program was successful so much so that illiteracy was significantly reduced in the country.
Although Abiy Ahmed's initiative in launching the program seems to be positive and perhaps a move in the right direction, especially if the program is given Ethiopian character as opposed to practices in the west, the political situation in the country could prove difficult to achieve the goals of the program.
This past week, for example, there has been an organized ethnic-based violence in Jijiga and other nearby towns, South Eastern parts of Ethiopia, where more than 29 people were killed and more than 10 churches were burned. Seen from that angle, it is questionable if it is the right time.

Chinese Cabbage
Curse of the bolting cabbage
A few years ago I began converting a portion of my cabbage harvest into stinky but mouthwatering kimchi.
Cravings for kimchi led to last year's troubled experiment with growing Napa cabbage – the traditional cabbage for making kimchi. Also known as Chinese cabbage (brassica rapa, Pekinensis Group), Napa is said to have more nutrients than other cabbage varieties.
I am a sucker for colorful, unusually-shaped vegetables so I bought seed for Scarlette Chinese Cabbage, a showy variety with bright magenta leaves, a pale yellow base, and contrasting white midribs. The catalog said these cabbages could bolt if exposed to temperature fluctuations as young seedlings but I didn't expect that to affect my plants.
The Scarlette Chinese cabbage seedlings were relentless. They crowded out other cabbage varieties in my seed flats and grew incredibly fast once transplanted into raised beds. They were a beautiful addition to the garden but quickly bolted. I salvaged a few loose heads for meals but mostly harvested cabbage greens. These became dehydrated vegetable flakes for an upcoming Arctic camping trip.
Chinese cabbage greens
Why did they bolt? Why would any self-respecting cabbage bolt?
The typical culprit for bolting vegetables in a well-maintained Alaska garden is the short nights of our growing season. Night duration impacts many plants through a phenomenon called photoperiodism, by which plants use their photoreceptors to measure the amount of light they receive. "Long day" plants like barley, spinach, radishes, and cilantro start flowering when nights are shorter. Short day plants like sunflowers need longer nights to start flowering.
Nurseries often use photoperiodism to trick plants into blooming but it seems to be less common for home gardeners to trick plants into not blooming. It's easier to avoid plants that bolt or look for bolt-resistant cultivars. Perhaps that's why photoperiodism is barely discussed in any of my gardening books.
All this aside, cabbages are usually categorized as "day neutral" plants, meaning they disregard day/night length. If they are bolting early in the season, it probably has nothing to do with photoperiodism.
Another culprit for bolting that might be relevant to my Chinese cabbage is called vernalization.
Vernalization is a beautiful word that describes how a period of cold weather is necessary for the flowering of many plants. It is more likely my Chinese cabbages bolted due to a cold spell in spring when I took my seedlings outdoors.
Other factors for bolting that are important to consider if day neutral plants are bolting include the soil quality, moisture level, and any other factor that might cause plant stress.
Chinese cabbage is a cool-weather crop that clearly wants to do well in my garden and I haven't given up on it yet. This year I'll wait to put seedlings outdoors until later in the spring when we aren't as likely to have cold snaps.
Maybe I'll make some scarlet kimchi after all.
Additional resources: I found a few good online resources for gardeners on photoperiodism, including a blog post from High Mowing Organic Seeds and an article from the Oregon State University Extension Service. Interesting scientific tidbits about photoperiodism and vernalization are shared in the book What a Plant Knows: A Field Guide to the Senses by Daniel Chamovitz.

 Does your bolted cabbage taste good for kimchi? We've been trying to grow michihili (cant think of spelling) chinese cabbage and buds started growing and got prickly..before it tried making a head. Cut them as.soon as we saw it, so hoping the leaves are good for kimchi.
 - Transcendental Gardening says:
 I didn't try that and supposedly kimchi mainly made from leafy parts is somewhat icky. So if you have leafy bolted cabbage, might be better as pesto or a green sauce? If you do have a lot of stem material, I'd say to go for it 🙂

How to Make an Oceanic Gope Board Part 3
Draw the shape for your Gope board. Make sure it is symmetrical and then cut it out. Next, fold the sheet of construction paper lengthwise. In cursive, write your name along the folded edge of the paper making certain that all letters set on the folded edge.
Fatten up the letters with the pencil and then cut out your name. Be careful not to cut apart any of your letters. Also, don't forget to cut out the openings in the letters and the areas along the folded edge. Glue the design onto another sheet of construction paper a bit different earthy color.
Cut out the name design leaving about a quarter inch border. Again, don't forget to cut out the openings of the letters then glue this onto your cardboard Gope board. Choose a border design from your patterns sheet and decorate with earth color such as browns, ochre, sienna, black and white, avoid blue and green.
Use markers or oil pastels. Apply a different pattern to your name design. For fun, choose some Papua New Guinea images to decorate the empty spaces of your board. Finish it off with some bundles of raffia and remember to have fun.

Suppose $p = 2^n - 1$ is prime. Show that $n \: | \: 2^n - 2$, or equivalently $n \: | \: p - 1$.
With hint: The order of any element in this field divides $p-1$.
Example: $n=7, \; p=127 \:\Rightarrow\: 7 \: | \: 126$.
I don't have any progress that seems to lead to a proof, but here are some of my ideas:
 - Because $p$ is a Mersenne prime, $n$ must be prime
 - Use Fermat's little theorem
 - Show that $2^n - 2 \equiv 0 \mod n$
share|improve this question
3 Answers 3
You have mentioned ingredients that lead to a proof. As you point out, the number $n$ must be prime, so we can use Fermat's Theorem.
There are a couple of different versions of Fermat's Theorem. Each version is not difficult to derive from the other.
Version 1: If $n$ is prime, then for any integer $a$, we have $a^n \equiv a \pmod n$. This says directly that $n$ divides $a^n-a$, which is exactly what you want to show, in the special case $a=2$.
Version 2: If $n$ is prime, and $n$ does not divide $a$, then $a^{n-1} \equiv 1 \pmod n$.
In your case, $n$ is odd, so if $a=2$, then $n$ does not divide $a$. It follows that $n$ divides $2^{n-1}-1$, and therefore $n$ divides twice this number, which is $2^n-2$.
However, you were given a hint which enables us to bypass Fermat's Theorem. So probably you were expected to argue as follows.
Since $p=2^n-1$, certainly $p$ divides $2^n-1$, so $2^n \equiv 1 \pmod p$. That implies that the order of $2$ in the field $\mathbb{Z}_p$ is a divisor of $n$. But the order of $2$ is exactly $n$, since $n$ is prime, and therefore the only divisors of $n$ are $1$ and $n$.
The order of any element of the field $\mathbb{Z}_p$ divides $p-1$. Since the order of $2$ in this field is $n$, we conclude that $n$ divides $p-1$, that is, $n$ divides $2^n-2$.

You said "$p$ divides $2^n-1$, so $2^n \equiv 1 \pmod p$". How does this step work? – Nayuki Minase Feb 27 '12 at 6:31
_USER_ Minase: We say that $x\equiv y \pmod m$ if $m$ divides $x-y$. Take $x=2^n$, $y=1$, $m=p$. Since definitely $p$ divides $2^n-1$ (in fact is exactly equal to $2^n-1$), we have $2^n\equiv 1 \pmod p$. – André Nicolas Feb 27 '12 at 6:38
Ohh right, I understand now. I guess I'm not comfortable enough with modular arithmetic that such an elementary fact slipped past me, heh. – Nayuki Minase Feb 27 '12 at 6:40
Alternate explanation: $p$ divides $2^n-1$, so $2^n-1$ divided by $p$ leaves no remainder, thus $2^n-1 \equiv 0 \mod p$. – Nayuki Minase Feb 27 '12 at 6:42
_USER_ Minase: I can see why it is puzzling, in a sense it is *too simple. One expects to have to work a bit to show that a congruence holds. In this case, there was no real work involved. – André Nicolas Feb 27 '12 at 6:44

Simpler answer:
Let $n \in \mathbb{N}^+$ be arbitrary. Let $p = 2^n-1$.
Clearly, $2^n \equiv 1 \mod {2^n-1}$. Moveover, $n$ is the smallest power where $2^n \equiv 1$. Thus the order of 2 in $\mathbb{Z}_{p}$ is $n$.
Now if $p$ is prime, then Fermat's little theorem guarantees that for any $a$ (except 0), $a^{p-1} \equiv 1 \mod p$. Furthermore, the order of $a$ divides $p-1$.
$a=2$ has order $n$, therefore $n$ divides $p-1 = 2^n - 2$, as wanted.
Complicated answer:
Fact: $x^{ab} - 1 = (x^a - 1)(x^{(b-1)a} + \ldots + x^{3a} + x^{2a} + x^a + 1)$. So for the special case of $2^n-1$, if $n$ is composite then $2^n-1$ can be factored. By contrapositive, if $2^n-1$ is prime then $n$ is prime.
Fermat's little theorem: If $q$ is prime, then $\forall a \in \mathbb{Z}, \; a^q \equiv a \mod q$.
Now, $n \: | \: 2^n - 2$ is equivalent to saying that $2^n-2$ is a multiple of $n$, or $2^n-2 \equiv 0 \mod n$.
We established that $n$ must be prime. By applying FLT with $a=2$, we get $2^n \equiv 2 \mod n$, which is easily equivalent to $2^n - 2 \equiv 0 \mod n$.

Hint $\rm\: prime\: P,\: A^P\!\! = 1 = A^K\!\Rightarrow A^{(P,\:K)}\!\!=1,$ so $\rm\: P| K\ $ [if $\rm (P,K) = P$]$\:$ or $\rm\: A\! =\! 1\:$ [if $\rm (P,K) = 1$]
For further detail see this question: If the order divides a prime P then the order is P (or 1).

VDC is said to be virtual device context, supported by Cisco NX-OS Software series. VDC helps in partition a single physical device to multiple logical devices which acts as unique and independent switch and has its own configuration and can be managed by separate administrator.
With VDC, We can manage multiple logical switch with in physical device, each VDC has its own unique set of L2 and L3 process, which runs on each of logical switches. We can treat these logical switches or these logical switch behaves same like physical switch which has its own set of L2 and L3 process and configuration running because each logical switch contains its own configuration file stored in NVRAM via VDC name and each logical devices has its own L2 and L3 control plane as we have like in each physical switch.
Following are benefits of VDC:
- Provides Fault isolation, if any fault occurs in any L2 or L3 process, it does not affect any other processes running on another logical switches.
- Provides management Isolation, each logical switches can be treated as individual switch and can be managed separately. It can be accessed by unique individual IP.
- Hardware Isolation, if any hardware resource is allocated to any VDC, it will be part of that VDC till the time, admin can reallocated it to any another VDC.
- Provides separation of data traffic at VDC level
- Provide enhance Security at VDC level.
VDC also virtualize the control plane like L2 tables (MAC tables), L2 Protocols, RIB and Routing protocols.
When any VDC is created, Control plane processes are replicated to all other VDC by NX-OS software. This replication enables VDC administrators use VLAN and VRF independently to those used in other VDCs. In Ethernet VDC, same VLANs numbers can be used across different VDC.

Sonora and ''the Green Revolution''
- Technical Specifications
||During the 1940s, the state of Sonora was greatly aided trough great hydraulic works in the area of irrigation as well as the establishment of programs such as ''the Green Revolution'' and allocation of land programs in the Yaqui and Mayo valleys. In the long run, it suffered the effects of the various economic crises that began in the 1970s, which also affected livestock raising and mining. This period's major issues are centered on phenomena such as migration and the establishment of border-area maquiladoras, which began transforming the state's production profile beginning in the seventies. The end of this era would be marked by the death of Sonora's Luis Donaldo Colosio in 1994.

The Lost Language Behind Project Unity
In our up-and-coming collection named Project Unity, we incorporate symbols from an ancient system of communications called Nsibidi, originating in southeastern Nigeria and southwestern Cameroon. The ideographic alphabet represented abstract concepts or actions, which enabled communication among various languages. Nsibidi consists of close to a thousand symbols that depict words like 'mirror', 'voyage', 'leopard skin', and 'unity', which we focus on in the new collection.Due to the presence of western education, Nsibidi, which was once looked at as a sacred language, is widely mysterious to modern Igbos and Ekoi. Though the use of the written language has reduced a considerable amount, artists like Obinna Igboobinna Eze has used it in his art to preserve the history of Nigeria before the arrival of Europeans. The major Marvel movie, Black Panther, also paid tribute to its African roots by using Nsibidi as an inspiration for the written Wakandan language seen on-screen. At Femi Aina New York, we strive to continue the importance of sharing the history of Nigeria through our clothing to spread awareness of our heritage and the beauty that lies within it.

Description of settings and properties of NetworkManager connection profiles
Description
NetworkManager is based on a concept of connection profiles, sometimes referred to as connections only. These connection profiles contain a network configuration. When NetworkManager activates a connection profile on a network device the configuration will be applied and an active network connection will be established. Users are free to create as many connection profiles as they see fit. Thus they are flexible in having various network configurations for different networking needs. The connection profiles are handled by NetworkManager via settings service and are exported on D-Bus (/org/freedesktop/NetworkManager/Settings/<num> objects). The conceptual objects can be described as follows:
Connection (profile)
A specific, encapsulated, independent group of settings describing all the configuration required to connect to a specific network. It is referred to by a unique identifier called the UUID. A connection is tied to a one specific device type, but not necessarily a specific hardware device. It is composed of one or more Settings objects.
Setting
A group of related key/value pairs describing a specific piece of a Connection (profile). Settings keys and allowed values are described in the tables below. Keys are also referred to as properties. Developers can find the setting objects and their properties in the libnm-core sources. Look for the *_class_init functions near the bottom of each setting source file.
The settings and properties shown in tables below list all available connection configuration options. However, note that not all settings are applicable to all connection types. NetworkManager provides a command-line tool nmcli that allows direct configuration of the settings and properties according to a connection profile type. nmcli connection editor has also a built-in describe command that can display description of particular settings and properties of this page.
connection setting
General Connection Profile Settings.
Key NameValue TypeDefault ValueValue Description
auth-retriesint32-1The number of retries for the authentication. Zero means to try indefinitely; -1 means to use a global default. If the global default is not set, the authentication retries for 3 times before failing the connection. Currently this only applies to 802-1x authentication.
autoconnectbooleanTRUEWhether or not the connection should be automatically connected by NetworkManager when the resources for the connection are available. TRUE to automatically activate the connection, FALSE to require manual intervention to activate the connection. Note that autoconnect is not implemented for VPN profiles. See "secondaries" as an alternative to automatically connect VPN profiles.
autoconnect-priorityint320The autoconnect priority. If the connection is set to autoconnect, connections with higher priority will be preferred. Defaults to 0. The higher number means higher priority.
autoconnect-retriesint32-1The number of times a connection should be tried when autoactivating before giving up. Zero means forever, -1 means the global default (4 times if not overridden). Setting this to 1 means to try activation only once before blocking autoconnect. Note that after a timeout, NetworkManager will try to autoconnect again.
autoconnect-slavesNMSettingConnectionAutoconnectSlaves (int32) Whether or not slaves of this connection should be automatically brought up when NetworkManager activates this connection. This only has a real effect for master connections. The properties "autoconnect", "autoconnect-priority" and "autoconnect-retries" are unrelated to this setting. The permitted values are: 0: leave slave connections untouched, 1: activate all the slave connections with this connection, -1: default. If -1 (default) is set, global connection.autoconnect-slaves is read to determine the real value. If it is default as well, this fallbacks to 0.
gateway-ping-timeoutuint320If greater than zero, delay success of IP addressing until either the timeout is reached, or an IP gateway replies to a ping.
idstring A human readable unique identifier for the connection, like "Work Wi-Fi" or "T-Mobile 3G".
interface-namestring The name of the network interface this connection is bound to. If not set, then the connection can be attached to any interface of the appropriate type (subject to restrictions imposed by other settings). For software devices this specifies the name of the created device. For connection types where interface names cannot easily be made persistent (e.g. mobile broadband or USB Ethernet), this property should not be used. Setting this property restricts the interfaces a connection can be used with, and if interface names change or are reordered the connection may be applied to the wrong interface.
lldpint32-1Whether LLDP is enabled for the connection.
llmnrint32-1Whether Link-Local Multicast Name Resolution (LLMNR) is enabled for the connection. LLMNR is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link. The permitted values are: "yes" (2) register hostname and resolving for the connection, "no" (0) disable LLMNR for the interface, "resolve" (1) do not register hostname but allow resolving of LLMNR host names If unspecified, "default" ultimately depends on the DNS plugin (which for systemd-resolved currently means "yes"). This feature requires a plugin which supports LLMNR. Otherwise the setting has no effect. One such plugin is dns-systemd-resolved.
masterstring Interface name of the master device or UUID of the master connection.
mdnsint32-1Whether mDNS is enabled for the connection. The permitted values are: "yes" (2) register hostname and resolving for the connection, "no" (0) disable mDNS for the interface, "resolve" (1) do not register hostname but allow resolving of mDNS host names and "default" (-1) to allow lookup of a global default in NetworkManager.conf. If unspecified, "default" ultimately depends on the DNS plugin (which for systemd-resolved currently means "no"). This feature requires a plugin which supports mDNS. Otherwise the setting has no effect. One such plugin is dns-systemd-resolved.
meteredNMMetered (int32) Whether the connection is metered. When updating this property on a currently activated connection, the change takes effect immediately.
multi-connectint320Specifies whether the profile can be active multiple times at a particular moment. The value is of type NMConnectionMultiConnect.
permissionsarray of string An array of strings defining what access a given user has to this connection. If this is NULL or empty, all users are allowed to access this connection; otherwise users are allowed if and only if they are in this list. When this is not empty, the connection can be active only when one of the specified users is logged into an active session. Each entry is of the form "[type]:[id]:[reserved]"; for example, "user:dcbw:blah". At this time only the "user" [type] is allowed. Any other values are ignored and reserved for future use. [id] is the username that this permission refers to, which may not contain the ":" character. Any [reserved] information present must be ignored and is reserved for future use. All of [type], [id], and [reserved] must be valid UTF-8.
read-onlybooleanFALSEFALSE if the connection can be modified using the provided settings service's D-Bus interface with the right privileges, or TRUE if the connection is read-only and cannot be modified.
secondariesarray of string List of connection UUIDs that should be activated when the base connection itself is activated. Currently only VPN connections are supported.
slave-typestring Setting name of the device type of this slave's master connection (eg, "bond"), or NULL if this connection is not a slave.
stable-idstring This represents the identity of the connection used for various purposes. It allows to configure multiple profiles to share the identity. Also, the stable-id can contain placeholders that are substituted dynamically and deterministically depending on the context. The stable-id is used for generating IPv6 stable private addresses with ipv6.addr-gen-mode=stable-privacy. It is also used to seed the generated cloned MAC address for ethernet.cloned-mac-address=stable and wifi.cloned-mac-address=stable. It is also used as DHCP client identifier with ipv4.dhcp-client-id=stable and to derive the DHCP DUID with ipv6.dhcp-duid=stable-[llt,ll,uuid]. Note that depending on the context where it is used, other parameters are also seeded into the generation algorithm. For example, a per-host key is commonly also included, so that different systems end up generating different IDs. Or with ipv6.addr-gen-

A Spiritual Successor is a type of sequel that is not part of the same world or story as its predecessor, but is nonetheless considered to be a successor because it's made by the same creators, shares common themes, styles, or elements; or, most likely, both. In other words, it's a sequel "in spirit".
A Spiritual Predecessor, on the other hand, is when a previous body of work has, somehow, paved the way for future, similar work, that is, again, not part of the same world, or universe, but shares a common connection in creators, themes, styles, or elements. In short, if it wasn't for the predecessor, other works might not have seen the light of day.
Examples are as follows
- Similar to the above mentioned, Bewitched itself also paved the way for other works to rethink its imaging of witches, thus, basically establishing the Cute Witch and Hot Witch tropes.
- Hanna-Barbera's The Banana Splits featured costumes and settings that were brought to life by Sid and Marty Krofft, and as such, impressed network executives, which opened doors for the Krofft brothers to venture into their own brand of Saturday Morning television.
- The Ed Sullivan Show helped garner Jim Henson national recognition, and a number of the skits, sketches, pantomimes, etc. that Henson and his team performed during their years appearing on the program were later established for the kind of humor and entertainment that became the focus of Henson's The Muppet Show.
- M*A*S*H set the bar for a many ensuing programs, whether for its medical accuracy and realism (ER, Grey's Anatomy), its balance of both comedy and drama (Desperate Housewives, Glee), utilizing multiple subplots per half-hour (Seinfeld), or its occasion forgoing of the laugh track (many of today's contemporary sitcoms omit laughter altogether, live or simulated).
- Both the original U.K., and the U.S. adapted versions of The Office established a new trend and tool for primetime television, with it's mockumentary-style story telling, paving way for other sitcoms, such as Parks and Recreation, Modern Family, The Middle, and others to do the same.
- Sesame Street is a big example of this, as it was the first of its kind in create a television series for young children that would both entertain, and educate them. The success of Sesame Street opened the door for a number of other such series, such as Barney & Friends, Teletubbies, Blues Clues, Dora the Explorer, and others (most of which, the creators have said they used Sesame Street as a model''.

Drawing Out the Gold
You are invited to an immersive exhibition by Katheryn Leopoldseder
Within a hallowed sepulchre, accompanied by sound and earthy smell, lies an exquisite Crown of Golden Alfalfa.
Drawing Out the Gold looks beyond the harsh means by which the artist's materials are mined and pays homage to scientific innovations that instead offer us an alternative; a collaboration with the ingenuity of the natural world.
Witnessing the decimation of his childhood land through industrial gold mining, nano-scientist Jorge Gardea-Torresdey discovered that Alfalfa can mine alluvial gold through phytoremediation; drawing precious metal from the soil into its roots, stems and leaves.
The Crown adorns the head, symbolising a shift in thinking. Its flat underside encircles the head like a halo. A historic reference to haloes depicted in religious art. Symbolising illuminated wisdom and bestowed authority.
To wear the Crown, materialises the potential of a collaboration between nature and humanity; into a signifier of royal identity; as people capable of positive stewardship of the earth.

I have a JDesktopPane and want to display JInternalFrames in a grid style without overlaying frames. The dymensions of the frames will vary so their location should be assigned dynamically. I could store the coordinates of the last placed frame but frames can be moved, minimized or closed.. Is their an easy way of placing internal frames in a tidy way? e.g., using a Layout?
share|improve this question
2 Answers 2
Here's an example that may offer some guidance. It uses setLocation() and an offset.
share|improve this answer
The DesktopManager class is responsible for managing the internal frames.
You should be able to override the openFrame() method to initially position the frame when it is added to the desktop.
There are also methods on dragging that you might be able to override to prevent the overlapping of frames.

Your Answer


the complete set of tags that should be associated with an instance whenever you update tags in this way.
To update tags using a direct API request:
 1. Determine the latest fingerprint associated with the tags. The fingerprint is used to prevent any collisions from simultaneous API requests. The process of updating network tags for an instance is similar to updating instance metadata.
 Perform a GET request to the instance; for example:
 GET _URL_

 Look for the tags.fingerprint property in the response:
 200 OK
 {
 ...
 "tags": {
 "items": [
 "http-server",
 "db-client"
 ],
 "fingerprint": "MW8EqhxILtc="
 },
 ...
 }

 You can also use a gcloud command to get the fingerprint, as shown in the following example:
 gcloud compute instances describe INSTANCE_NAME \
 --zone ZONE \
 --format="get(tags.fingerprint)"
 2. Make a POST request to the instance().setTags method. The request body must contain all of the tags that should be associated with the instance along with the fingerprint value.
 Example request:
 POST _URL_
 {
 "items": [
 "http-server",
 "db-client",
 "allow-internet-access"
 ],
 "fingerprint": "MW8EqhxILtc="
 }

 Example response:
 200 OK
 {
 "kind": "compute#operation",
 "id": "9251830049681941507",
 "name": "operation-1442414898862-51fde63aa57b1-422323e0-c439fb04",
 "zone": "_URL_
 "operationType": "setTags",
 "targetLink": "_URL_
 "targetId": "4392196237934605253",
 "status": "PENDING",
 "user": "_EMAIL_",
 "progress": 0,
 ...
 }

Teralfene is a village in the municipality of Affligem, Belgium. It has an area of 244 ha (602.94 acres). The other communities in Affligem are Hekelgem and Essene.
The name "Teralfene" originates from the brook Alfene (now called the Bellebeek) which flows into the Dender. The oldest reference to the village is Iuxta Alfnam (+- 1142)
During the post-Carolingian period, Teralfene belonged to the shire of Brabant. As from 1056 it was part of a German fief that was granted to the counts of Flanders (the so-called Imperial Flanders). During the French period (_PHONE_) Teralfene was part of the Dijle-territory. During the Dutch period (_PHONE_), this department was transformed to the province Zuid-Brabant by Willem I of Orange. Until the end of 1976, Teralfene was an independent municipality.
This list contains the known mayors of Teralfene until the merger into Affligem.
Before Teralfene became part of Affligem, two political parties were prominent at the local level: the Dries and the Daal-party, each named after an area of the village. Both parties originated from a disagreement over an inheritance, and divided Teralfene since 1850. The Daal and Dries parties had about equal power, and election victories switched constantly for over 100 years.
After the merger into Affligem, other parties (CVP, SP, VU and PVV) gained popularity, and the Daal and Dries parties dissolved.

Using a "strawman" for page layout design
Designing the page layouts for a new or redesigned intranet can be complex. One of the most difficult aspects is creating the first layout. Starting with an empty screen, you need to determine what will go on each page and where it will go.
Using a strawman design – a design that is created with the intent of discarding it – can help to overcome many of the difficulties in the design process.
Team or individual
It is simple for one member of the intranet team to create a set of page layouts. They can use the information such as user research, intranet goals and key page elements to design the first layouts. Unfortunately, during layout discussion the team member may think that their ideas are being attacked.
Involving the whole intranet team brings together a range of experiences, skills and understanding of the intranet needs. The eventual design should be richer for the input. However, it is difficult to design as a team – it can be hard to move beyond the blank slate and communicate design ideas. Some team members may be good at discussing abstract concepts but many won't. Designing in this situation can be frustrating and unproductive.
Using a strawman
An approach that we have used successfully is to use a strawman design. The strawman is created with the intent that it will be pulled apart and discarded. It is used to encourage discussion of the layout's strengths and weaknesses and to generate better designs.
The key advantage of a strawman is that it provides something concrete to discuss. The team can point to it, sketch on it, discuss why an element won't work or what they would prefer to see. It allows the team to discuss the layout without it being abstract.
Creating the strawman
The strawman should show the position of key elements including a banner, navigation, search box and page content. It doesn't need to be either complete or very detailed and may contain elements that will be contentious. It should be hand drawn on paper or on a whiteboard.
Runing a strawman design session
A strawman design session needs to be managed by a facilitator. This person listens to suggestions, clarifies issues, and summarises ideas.
The input to the session (an information architecture diagram, personas, key tasks, intranet goals) should be available, preferably hung up on walls where everyone can see them.
Everyone should be given markers and there should be plenty of paper available for sketching. It can be good to use two whiteboards – one for the evolving design and one for interim sketches. An internet connection is useful to examine sites with particular features of interest.
The facilitator should make sure that everyone knows that the initial and evolving design is a strawman so they feel comfortable discussing it.
The team starts with a discussion of things that are good and bad about the strawman. As issues are discussed, alternatives can be generated and the facilitator can re-sketch parts of pages. The team should be encouraged to sketch and show their ideas to keep the session practical. Each sketch is considered a new strawman and open to further discussion.
During the session take time to break and step back from the activity. Keep an open mind and remember to focus on the user needs and intranet goals.
Most importantly, have fun!

Ojibwe Place Names in Wisconsin, ca. 1890
Geographical Names in Wisconsin, Minnesota, and Michigan, Having a Chippewa origin
The author of this list, Chrysostom Verwyst (_PHONE_), was a Catholic missionary among the Ojibwe in the Bayfield-Ashland area from 1882 to 1912. Verwyst became fluent in Ojibwe and after retiring spent his remaining years in the Franciscan monastery at Bayfield, where he wrote on the history and language of the Ojibwe and compiled a biography of his predecessor, Rev. Frederic Baraga. This list preserves the Ojibwe names in use in northern Wisconsin at the start of the 20th century; Verwyst also occasionally ascribed Ojibwe origins to place names that modern linguists now believe actually came from other lagnuages. It is one of several works in or about American Indian languages to be found at Turning Points in Wisconsin History. Readers should note that this is a historical document rather than a modern one; students wishing to study the language should rely on materials produced by the tribal language office.

Main Idea
The main idea of admiral is that an ADaM dataset is built by a sequence of derivations. Each derivation adds one or more variables or parameters to the processed dataset. This modular approach makes it easy to adjust code by adding, removing, or modifying derivations. Each derivation is a function call. Consider for example the following script which creates a (very simple) ADSL dataset.
Load Packages and Example Datasets
First, we will load our packages and example datasets to help with our ADSL creation. The dplyr and lubridate packages are tidyverse packages and used heavily throughout this script. The admiral package also leverages the {admiral.test} package for example SDTM datasets which are from the CDISC Pilot Study.
library(dplyr, warn.conflicts = FALSE)
library(lubridate)
library(admiral)
library(admiral.test)
# Read in SDTM datasets
data("admiral_dm")
data("admiral_ds")
data("admiral_ex")
dm <- admiral_dm
ds <- admiral_ds
ex <- admiral_ex
Derive Treatment Variables (TRT0xP, TRT0xA)
The mapping of the treatment variables is left to the ADaM programmer. An example mapping may be:
adsl <- dm %>%
 mutate(TRT01P = ARM, TRT01A = ACTARM)
Derive/Impute Numeric Treatment Date/Time and Flag Variables (TRTSDTM, TRTEDTM, TRTSTMF, TRTETMF)
The function derive_vars_dtm() can be used to convert the DTC variables from EX to numeric datetime variable and impute missing components. The function call returns the original data frame with the column EXSTDTM, EXENDTM and corresponding time imputation flag variables EXSTTMF and EXENTMF added to the end of the dataframe. Exposure observations with an incomplete date are ignored. We impute missing time to be 23:59:59 using time_imputation = "last". The required imputation flags are determined automatically by the function. Here only time imputation flags are derived because time is imputed but date is not imputed.
Don't be intimidated by the number of arguments! We try to make our arguments self-explanatory, e.g. the new_vars_prefix places EXST at the start of the --DTM variable and time_imputation = "last" appends 23:59:59. However, this is not always possible to make every argument self-explanatory. If you click on the function, derive_vars_dtm(), you can bring up the reference documentation and learn more about each argument.
# Derive treatment variables
## Impute time of exposure dates (creates numeric datetime and time imputation flag variables)
ex_ext <- ex %>%
 derive_vars_dtm(
 dtc = EXSTDTC,
 new_vars_prefix = "EXST"
 ) %>%
 derive_vars_dtm(
 dtc = EXENDTC,
 new_vars_prefix = "EXEN",
 time_imputation = "last"
 )
## Derive variables for first/last treatment date and time imputation flags
adsl <- adsl %>%
 derive_vars_merged(
 dataset_add = ex_ext,
 filter_add = !is.na(EXSTDTM),
 new_vars = vars(TRTSDTM = EXSTDTM, TRTSTMF = EXSTTMF),
 order = vars(EXSTDTM, EXSEQ),
 mode = "first",
 by_vars = vars(STUDYID, USUBJID)
 ) %>%
 derive_vars_merged(
 dataset_add = ex_ext,
 filter_add = !is.na(EXENDTM),
 new_vars = vars(TRTEDTM = EXENDTM, TRTETMF = EXENTMF),
 order = vars(EXENDTM, EXSEQ),
 mode = "last",
 by_vars = vars(STUDYID, USUBJID)
 )
Derive Date Variables from Date/Time Variables (TRTSDT, TRTEDT)
The datetime variables returned can be converted to dates using the derive_vars_dtm_to_dt() function.
adsl <- adsl %>%
 derive_vars_dtm_to_dt(source_vars = vars(TRTSDTM, TRTEDTM))
Derive Treatment Duration (TRTDURD)
Now, that TRTSDT and TRTEDT are derived, the function derive_var_trtdurd() can be used to calculate the Treatment duration (TRTDURD). Notice the lack of inputs. The function defaults are set to TRTSDT and TRTEDT. Clicking on derive_var_trtdurd() will bring up the reference documentation where you can see the default arguments.
adsl <- adsl %>%
 derive_var_trtdurd()
Amazing! With one dplyr function and four admiral functions we successfully created nine new variables for our ADSL dataset. Let's take a look at all our newly derived variables.
Note: We only display variables that were derived. A user running this code will have additional adsl variables displayed. You can use the Choose Columns to Display button to add more variables into the table.
Derivations
The most important functions in admiral are the derivations. These functions start with derive_. The first parameter of these functions expects the input dataset. This allows us to string together derivations using the %>% operator.
Functions which derive a dedicated variable start with derive_var_ followed by the variable name, e.g., derive_var_trtdurd() derives the TRTDURD variable.
Functions which can derive multiple variables start with derive_vars_ followed by the variable name, e.g., derive_vars_dtm() can derive both the TRTSDTM and TRTSTMF variables.
Functions which derive a dedicated parameter start with derive_param_ followed by the parameter name, e.g., derive_param_bmi() derives the BMI parameter.
Input and Output
It is expected that the input dataset is not grouped. Otherwise an error is issued.
The input dataset should not include variables starting with temp_. These variable names are reserved for temporary variables used within the derivation and are removed from the output dataset. If the input dataset contains such variables, an error is issued.
It is expected all variable names are uppercase in the input dataset and new variables will be returned in uppercase.
The output dataset is ungrouped. The observations are not ordered in a dedicated way. In particular, the order of the observations of the input dataset may not be preserved.
Computations
Computations expect vectors as input and return a vector. Usually these computation functions can not be used with %>%. These functions can be used in expressions like convert_dtc_to_dt() in the derivation of FINLABDT in the example below:
# Derive final lab visit date
ds_final_lab_visit <- ds %>%
 filter(DSDECOD == "FINAL LAB VISIT") %>%
 transmute(USUBJID, FINLABDT = convert_dtc_to_dt(DSSTDTC))
# Derive treatment variables
adsl <- dm %>%
 # Merge on final lab visit date
 derive_vars_merged(
 dataset_add = ds_final_lab_visit,
 by_vars = vars(USUBJID)
 )
Parameters
For parameters which expect variable names or expressions of variable names, symbols or expressions must be specified rather than strings.
 - For parameters which expect a single variable name, the name can be specified without quotes and quotation, e.g. new_var = TEMPBL
 - For parameters which expect one or more variable names, a list of symbols is expected, e.g. by_vars = vars(PARAMCD, AVISIT)
 - For parameters which expect a single expression, the expression needs to be passed "as is", e.g. filter = PARAMCD == "TEMP"
 - For parameters which expect one or more expressions, a list of expressions is expected, e.g. order = vars(AVISIT, desc(AESEV))
Handling of Missing Values
When using the haven package to read SAS datasets into R, SAS-style character missing values, i.e. "", are not converted into proper R NA values. Rather they are kept as is. This is problematic for any downstream data processing as R handles "" just as any other string. Thus, before any data manipulation is being performed SAS blanks should be converted to R NAs using admiral's convert_blanks_to_na() function, e.g.
dm <- haven::read_sas("dm.sas7bdat") %>%
 convert_blanks_to_na()
Note that any logical operator being applied to an NA value always returns NA rather than TRUE or FALSE.

The Spice Mix Super Computer was a part of the Abandon Normal Devices in Manchester, England this weekend. The AND festival commissioned the Center for Genomic Gastronomy to create a new work inside a traveling caravan and this is what we made:
The Centre for Genomic Gastronomy had deigned a exciting new culinary commission, the Spice Mix Super-Computer! The Spice Mix Super-Computer is a massive mobile food machine, which allows users to create, print and taste a unique blend of spices from millions of possible combinations. First, plug into the bespoke Olfactory Synthesizer to combine and compare smells from our database of international spices. Then, choose your favorite spices and watch the computer process and interpret your selection. After the food-printing is complete, take your customized container of spice to the BetaTaster™ food counter and share your recipe and experience, and take home your spice mix to share with others.
Spices as Social Media
Spices are one of the oldest forms of long distance communication on the planet, but we do not usually treat them as information that can be combined and disseminated as a form of human-to-human communication. Digital technology has created opportunities for individuals to mix and share images and sounds across great distances, but not flavors and smells. This project assembles spices from all over the globe, allowing individuals to customize, mix and spread smell and taste messages with other humans.
The Spice Mix Super-Computer is designed to record and store every possible spice combination, analyzing user preferences and patterns along the way. We hope this data will begin to reveal the underlying structures and the role of spices in the agri-eco-culinary system. Are combinations of spices strange attractors, naturally aligning, or can we open our mouths and minds to novel combinations of smell, taste and chemical reaction?
Spices Change Minds
But be careful: spices are dead and dried plant corpses with the substantial power to direct and regulate human activity. Many spices come from poisonous plants, and have powerful physical and mental effects on humans. If you are mixed up with spices how do you know they are not using you to achieve their dark designs? Might a heretofore untasted spice combination unlock a door to unexpected culinary experiences and states of consciousness? There are not enough BetaTasters™ on the planet asking these questions. The Spice Mix Super Computer can help.

For dragons to breath fire is certainly possible to have happened. Today fireflies produce light, eels produce electricity and the bombardier beetle can produce fire. The bombardier beetle has a canon near his rear end where he can blast his enemies with chemicals that are 212 degrees Fahrenheit: the temperature of boiling water. How does the beetle do that? This beetle has compartments where he stores fiery chemicals. When these chemicals unite they explode. If a tiny beetle can possess such a sophisticated mechanism in its rear, then a dinosaur or dragon could also have had a similar mechanism that would allow it to breathe fire to defend itself.
In fact, some of the dinosaurs have compartments in their heads that are connected to their nasal passages. The Tyrannosaurs Rex has a head the size of a car but his brain was the size of a baseball. The rest of his head was full of these compartments connected to his sinuses. If he had these special chemicals stored in these hollow compartments, it is possible that he could have been a fire breathing dragon.
In addition, legends of fire breathing dragons have circulated around the world for centuries and throughout history. They are depicted in artwork and literature. Almost all cultures have dragon legends despite having had no contact with each other.

White Forest
From Valve Developer Community
Jump to: navigation, search
White Forest is a secluded rebel outpost in the outskirts of City 17. It is one of the new locations in Half-Life 2: Episode Two.
White Forest is a decommissioned Cold War-era Soviet missile silo that was acquired by Black Mesa late in its history, though no apparent signs of this can be seen. By the time of the game it has become an important rebel HQ. Much of the base lies underground; it features many essential facilities such as communication rooms, pump stations, a garage, a helicopter hangar, and a launch control center. Also included are two missile silos: the primary silo is in use for building the rocket instrumental in closing off the Citadel superportal, and the secondary silo is abandoned. An enormous double antenna tower stands above the primary silo, serving as a notable landmark for the base as a whole. Certain concrete bunkers on the surface, while not visited, can be assumed to contain personnel quarters, and an unseen staff room is mentioned. In the compound itself, while players will often find themselves in narrow corridors, navigation is fairly straightforward.
Materials typically consist of bare concrete bunker walls, dirty concrete floors and rusted metal for frames and beams. Some walls have a coat of white paint with a green stripe along the bottom. Outside, the concrete is rougher and often overgrown with moss or covered under a layer of dirt and grass.
The base is located in a hilly and densely forested area, making it more difficult to access. On its southern side there is a deep valley with a shallow river which leads to one of the entry points to the base. To the north lies another, more expansive valley with smaller buildings, such as a sawmill, and other landmarks including a watertower, a single-track railway supposedly leading into the base, and two logging cranes. Many of these only appear to be there for scenic or referential reasons. Additionally, both valleys are connected through the garage within the base.
Inside, in line with its original military purpose, White Forest consists of utilitarian spaces commonly filled with computer equipment for rocket launch and surveillance monitoring as well as fuel/water lines and storage shelves. However, some of the places are more lived-in, such as one of the control rooms being partially repurposed as lounge. Pipes and wiring are ubiquitous throughout the environment, as are blast doors separating most hallways, and floors are usually littered with sheets of cardboard and plywood. Despite the base's derelict status, there are no immediate signs of disuse in the more occupied areas, suggesting some amount of upkeep, though parts of debris can be seen in unreachable areas outside, and the abandoned secondary silo is crumbling. Lighting primarily consists of warm colors, with pale white and hazard red lights seen in the more technical areas. Some of the compound's Soviet legacy is still present in the form of Russian signage for the various facilities and the red star symbol.
The base is the current residence of Dr. Kleiner, Eli Vance and a new character, Dr. Magnusson, accompanied by a small garrison of rebel fighters, workers and technicians. Judith Mossman also stayed here at some point before her disappearance. The base is subject to multiple attacks. First, Combine Soldiers and Hunters invade the base by breaching through the secondary silo, and later Striders escorted by Hunters attempt to destroy the rocket silo from the outside. The player must fend off the Strider attack using a new weapon introduced in Episode Two, called the Magnusson Device.

Hartmann, Stephan (2012): Generalized Dicke States.
Full text not available from 'Open Access LMU'.
Abstract
Quantum master equations are an important tool in quantum optics and quantum information theory. For systems comprising a small to medium number of atoms (or qubits), the non-truncated equations are usually solved numerically. In this paper, we present a group-theoretical superoperator method that helps solving these equations. To do so, we exploit the SU(4)-symmetry of the respective Lindblad operator and construct basis states that generalize the well-known Dicke states. This allows us to solve various problems analytically and to considerably reduce the complexity of problems that can only be solved numerically. Finally, we present three examples that illustrate the proposed method.

Sadie T.M. Alexander
QUick Look At Alexander
Sadie T.M. Alexander was an African American attorney whose greatest accomplishments were becoming the first-ever Black woman to be admitted to the Pennsylvania Bar, and being one of the first women to earn a doctorate in America.
Early Life and Education
Sadie Tanner Mossell Alexander was born in Philadelphia, Pennsylvania, in 1898. Alexander's father was an attorney, but he left the family when she was just one year old and her mother suffered from depression. Her extended family was very involved. Alexander's grandfather was the editor of the AME Church Review and the Cristian Recorder. Her uncle founded Frederick Douglass Hospital, and her aunt founded the Nurse's School and Hospital at Tuskegee Institute. Alexander went to high school in Washington D.C. at M Street High School, which is now Dunbar High School. After graduating high school, she received a scholarship to Howard University but her mother insisted that she go to the University of Pennsylvania. In school, Alexander faced discrimination from her teachers and fellow students. In 1918, she graduated with her B.S. and M.A. in economics. In 1919, she became the first national president of the Delta Sigma Theta sorority. In 1921, Alexander earned her doctorate in economics, making her one of the first Black women, and one of the first women to earn a doctorate degree.
After getting her doctorate, she worked as an actuary for a Black-owned life insurance company, the North Carolina Mutual Life Insurance Company. She stayed there for two years before moving back to Pennsylvania, where she married Raymond Pace Alexander. She and Raymond had four daughters, but two of those daughters died when they were babies. The surviving two were named Mary, after Alexander's mother, and Rae. In 1924, she enrolled in the University of Pennsylvania School of Law, making her the first Black woman to ever do so. She graduated with honors, and in 1927, she became the first-ever Black woman admitted to the Pennsylvania Bar. She was also the first African American to hold both a Ph.D. and a J.D. Alexander worked for the city of Philadelphia as an Assistant Solicitor before joining her husband's law firm, where they called their partnership Alexander & Alexander. They were one of the first married legal teams in the U.S. She focused on racial discrimination, segregation, and employment inequality cases. After four years of working with her husband, Alexander reclaimed her position as Assistant Solicitor for Philadelphia. While in this position, she created a legal aid bureau specifically to help African Americans who could not afford lawyers. In 1947, she was appointed to President Harry S. Truman's Committee of Human Rights. This committee's work led to the criminalization of lynching. Alexander continued to practice law until retiring in 1982. She died due to complications of Alzheimer's in 1989 at 91 years of age.
Sadie Tanner Mossell helped many people get legal services and she helped make a countrywide difference in illegalizing lynching. She also broke through many racial barriers in her career.


Weekly driver 1 & 2: L3GD20, LSM303DLHC and Madgwick
February 19, 2018 by Jorge Aparicio
Oh, time flies. It's already week 8 and we have zero weekly driver posts out there – don't worry though because there's plenty of drivers and embedded-hal implementations in the works.
To play catch up in this post I'll cover two embedded-hal drivers: the l3gd20 and the lsm303dlhc. The L3GD20 is an IC that contains a gyroscope and exposes I2C and SPI interfaces; the LSM303DLHC is an IC that contains an accelerometer and a magnetometer, and exposes an I2C interface. You can find these two ICs on the STM32F3DISCOVERY board.
Gyroscope, accelerometer and magnetometer – all these are motion sensors. On their own they aren't that useful because each one has some sort of weakness but when you put them together you can build some nifty stuff.
Even though the L3GD20 has I2C and SPI interfaces the l3gd20 driver only lets you interface the L3GD20 using SPI. Coincidentally, on the STM32F3DISCOVERY board the L3GD20 is connected to the SPI bus of the STM32F303 microcontroller.
The L3GD20 contains a gyroscope, but what's a gyroscope useful for?
A gyroscope is a sensor that measures the angular rate exerted on it. Angular rate is basically the speed at which something is rotating, and it's measured in degrees per second or in radians per second. Gyroscopes like the L3GD20 measure a 3D angular rate but report it as angular rates across three orthogonal axes. See picture below:
So the L3GD20 will report an angular rate across its X axis, another one across its Y axis and yet another across its Z axis.
Going back to the l3gd20 driver. Once you create an instance of the driver you can read the sensor using the blocking gyro() method. The method returns an I16x3 value which contains the readings of the sensor along its X, Y and Z axes.
let mut l3gd20 = L3gd20::new(spi, nss)?;
let I16x3 { x, y, z } = l3gd20.gyro()?;
Each reading is a 16 bit integer that represents an angular rate. To map this integer to degrees per second you need to multiply it by the sensitivity of the sensor. The L3GD20 defaults to a sensitivity of 8.75e-3 dps / LSB (dps = degrees per second; LSB = Least Significant Bit); this maps the 16 bit integer to a range of about [-250, 250] degrees per second.
If we collect data from the gyroscope while keeping the F3 board still we'll see something like this:
AR_x stands for Angular Rate across the X axis; |AR| is the magnitude of the 3D angular rate. The blue line is sensor data collected during the span of one second and the green line is the mean of the data.
There's a problem with this data though: it says that the mean angular rate is not zero, which implies that the L3GD20 and the F3 board to which is attached are rotating. We know that was not the case: the board was kept still while measuring so the all the readings should be centered around zero but instead they are offset by some value. This offset is known as bias and it's commonly found on gyroscopes and other kind of sensors.
To correct this bias error we have to calibrate the gyroscope. But turns out we kind of already did: the mean values we computed in the previous graph are the biases of the gyroscope. The only thing that's left is to subtract the bias from each axis measurements.
Now these are more correct measurements!
We can calibrate the gyroscope for bias while the gyroscope / board is not moving so we can do that each time the system is initialized if we know that the board is still during initialization. The problem is that bias doesn't remain constant in time; it tends to drift with both the passage of time and with changes in temperature so the calibration will eventually become invalid. There are methods to compensate for bias drift but I won't cover them here.
Let's move on to the next IC.
This IC contains an accelerometer and a magnetometer. Let's look at each of them in detail.
Accelerometers are sensors that measure proper acceleration. In simple terms, the difference between proper acceleration and the coordinate acceleration you are familiar with is that proper acceleration includes the acceleration of gravity. This means that even if an accelerometer is not moving it will sense the acceleration of the gravity.
Like the gyroscope in the L3GD20, the accelerometer in the LSM303DLHC measures a 3D acceleration vector but it reports the decomposition of the 3D vector along three orthogonal axes.
Using the lsm303dlhc driver is similar to using the l3gd20 driver. Once you instantiate the driver you can read the accelerometer data using the blocking accel() method.
let mut lsm303dlhc = Lsm303dlhc::new(i2c)?;
let I16x3 { x, y, z } = lsm303dlhc.accel()?;
Again, you get a 16 bit integer for the reading along each axis. The default sensitivity of the accelerometer is around 6.1e-5 g / LSB (g is the acceleration of gravity); this maps the integer to a range of [-2, 2] g.
If we collect data from the accelerometer while keeping the F3 board still on a horizontal surface we'll see something like this:
G_x stands for acceleration of Gravity across the X axis; |G| is the magnitude of the acceleration of Gravity. The blue line is sensor data collected during the span of one second and the green line is the mean of the data.
This accelerometer could use some calibration because the X and Y components should have a mean of zero and the Z (down) component should have a mean of 1g but that's not that critical for the demo so I'll skip it.
Magnetometers are sensors that measure magnetic fields. In the absence of nearby magnets a magnetometer will measure Earth's magnetic field, which points to the geographic north (unless you are too close to the poles, I suppose), so you can use the magnetometer as digital compass.
Earth's magnetic field is a 3D vector but the magnetometer in the LSM303DLHC decomposes it along three orthogonal axes.
The lsm303dlhc driver provides a blocking mag() method to read the magnetometer data.
let I16x3 { x, y, z } = lsm303dlhc.mag()?;
As with the other methods, you'll get a 16 bit integer for each axis.
Below is shown a magnetometer reading obtained while the F3 board was sitting still on a horizontal surface. No scaling (multiply by the sensitivity) was performed.
I16x3 { x: 26, y: -167, z: -553 }
From the X and Y components you can compute where north is in the horizontal XY plane. For instance, if the X component is zero and the Y component is non zero then north is aligned to the Y axis of the magnetometer. The Z component, the vertical component of Earth's magnetic field, varies with latitude; it should be close to zero when the measurement is done on the equator.
Like the gyroscope, the magnetometer also suffers from bias. Furthermore, the metal components on the board itself can strengthen / weaken nearby magnetic fields; this results in different per axis sensitivities so a magnetic field of constant magnitude can be perceived as having different magnitudes when measured along the different axes of the magnetometer.
As Earth's magnetic field magnitude is roughly constant, ideally we should measure it as having the same magnitude regardless of the orientation of the magnetometer. We'll use this fact to calibrate the magnetometer and compensate for the ferromagnetic properties of the board.
Assuming the only magnetic field the magnetometer is sensing is the Earth's we should observe that all the magnetometer readings satisfy the following equation:
mx * mx + my * my + mz * mz == K // Eq. 1
Where mx is the reading along the X axis, my is the reading along the Y axis, mz the reading along the Z axis, and K is some constant.
This also happens to be the equation of a sphere centered at coordinate (0, 0, 0) so if we plot the readings in 3D space we should see that all of them lie on the surface of a sphere.
To calibrate the magnetometer we'll collect measurements from the magnetometer in different orientations. We'll do that by logging data while the board in being rotated in different ways. See video below for a demo of what I mean.
IMPORTANT While logging calibration data keep the magnetometer away from sources of electromagnetic fields (EMF). The above video is actually a bad example in that regard because the EMF that the laptop emits heavily affect the magnetometer readings – the laptop EMF can easily double the magnetometer readings.
Here's the data that was collected over the lapse of 32 seconds of motion.
Plot M_XY is a scatter plot of the magnetometer readings along the X axis vs the readings along the Y axis. Plots M_XZ and M_YZ are similar but involve a different pair of axes.
Remember that I said that the readings plotted in 3D space should look like a sphere? These first three plots are like the projections of that

Plasma deposited thin films are very promising for the development of innovative gas sensors based on plastic optical fibres (POF). POFs exploit the evanescent field interaction, so that the sensors can be produced by depositing a sensing thin film onto the fibre surface and measuring the light transmittance change because of its reaction with the gas. A standard, low-cost, commercial step-index, highly multimode POF was used to set up cumulative sensor prototypes to detect H2S vapours in low concentration. The approach proposed for the realization of the sensors foresees the surface modification of the plastic optic fibre in two steps: (1) etching of the cladding by means of ethyl-acetate and (2) deposition of an Ag nanostructured sensing film by plasma sputtering. The study of the gas diffusion/reaction process occurring onto the fibre surface is a fundamental step to arrange simple and low-cost devices characterized by high sensitivity and high selectivity towards the gas of interest. This process depends on many parameters connected to the sensing layer chemistry and morphology and are, consequently, complex and difficult to predict. The POF-based approach was employed also for monitoring the gas diffusion/reaction process through the sensing layer to model the process itself and to understand how it can affect the expected sensor response.

PennController.GetTable( tablename ).filter( "column", "match" )
PennController.GetTable( tablename ).filter( "column", /match/ )
PennController.GetTable( tablename ).filter( function )
Returns a filtered version of the table, containing only rows whose specified column's value is a match.
If you use a string then the column's value must match the text exactly. Alternatively, you can use a regular expression to test the column's value. You can also use a function that will take each row as an argument and should return
true to keep the row or
false to exclude it.
You can use several
filters in chain.
Template( GetTable( "spreadsheet.csv" ).filter( row => row.Item > 0 ) // 'Item' should be greater than 0, and.filter( "ButtonText", /second/ ) // 'ButtonText' should contain'second', row => newTrial( "button trial", newButton("test button", row.ButtonText).print().wait() ).log( "Item", row.Item ).log( "Text", row.ButtonText ) );
Generates only one trial from a subset of the table spreadsheet.csv: first we only consider rows where the value in the Item column is a number greater than 0 (this is practically ineffective, for both rows in spreadsheet.csv already satisfy this condition) and we further consider only rows among those rows where the value of the ButtonText column is a text containing the string second (only the second row satisfies this condition).

Simple and clean measuring of powder and bulk materials.
The innovative flow metering system for freely falling bulk material provides the ability to conduct an optimal control of process parameters in hygienically demanding areas. The dead-space-free stainless steel housing and the measuring cells located outside the measuring chamber enable an easy cleaning and sterilizing of the measuring device. This increases the efficiency of the plant without requiring an expansion of the measuring system.
Powder and bulk solids are conveyed shock-free onto a concave measuring cone through a feed mechanism within the measuring device which acts as the device's sensor. The cone deflects the bulk material and generates a force. The downward acting component of the developing centripetal force is detected by a series of measuring cells which are located outside of the measuring chamber and transmit to a digital transducer. This measurement principle is able to achieve a measurement uncertainty of up to ± 0.5 % – a measurement accuracy of 99,5 %.

Meteorological Images of March 2013
A Matter of Degrees
Image credit: NOAA
And, last but not least, the most notorious happening in weather in the U.S. in March 2013. During the storm which got the "S" name on The Weather Channel's list - Saturn - the atmosphere in the nation's capital was teetering on the edge between being just cold enough for snow or a little too warm, while just to the west there were big accumulations in places such as Front Royal. The difference between, say, 72 and a few degrees higher usually doesn't matter much in weather, but the difference between 32 and 38 sure can!
This graph is of a "short range ensemble forecast" (SREF) model prediction of temperatures for Reagan National Airport for March 6-7. The lines show "ensemble members," in which a bunch of forecasts are made by the model with the goal being to depict a range of possible outcomes and the degree (pun intended) of uncertainty. Well, in this case the actual temperatures - the dots - were consistently higher throughout the storm than most of those members, and increasingly outside the range on the afternoon of the 6th, a key time for potential snow accumulations. That meant the difference between "Snowquester," as some were calling the storm, and it turning into "Noquester."
