Taiwanese multinational network company D-Link and American fabless semiconductor specialists Silicon Labs have released the world's first "Thread Group"-certified router, the DSH-G300-TBR Border Router.
Thread is an IP-based wireless networking protocol supported by the non-profit Thread Group, which is backed by Arm, Intel, Qualcomm, Siemens and more. It was set up to help accelerate adoption of the Internet of Things, specifically in the connected home.
D-Link's Thread Border Router can support multiple protocols such as ZigBee, Thread and Bluetooth, giving the user the option to automate their home devices by combining a wide range of sensors and home devices together.
(In a Thread mesh network, border routers connect the Thread network and an external network, linking nodes on the Thread network to other devices in external networks or to the cloud.)
The router uses the Linux operating system, embedded into the device on the main CPU alongside a Silicon Labs MGM12P ZigBee module that can either be pre-loaded on a ZigBee stack or on Thread. Alongside this, D-Link's Thread Border Router runs on Silicon Lab's multiprotocol Wireless Gecko System on a Chip (SoC).
What is Thread Again?
Thread is a mesh network that is designed to securely and reliably connect to hundreds of products in the home without blowing up battery life or causing interoperability issues.
A Thread network uses the latest 6LoWPAN technology; a combination of IPv6 and Low-power Wireless Personal Area Networks. 6LoWPAN can allow small devices with limited processing ability to transmit information wirelessly.
Thread networks are encrypted and use the latest smartphone authentication scheme and Advanced Encryption Standard to close security holes that would have existed within other wireless protocols.
Low Power, Latest Bluetooth Tech
D-Link's Thread Border Router comes with the latest Bluetooth technology, including Bluetooth Low Energy, Bluetooth 5 and Bluetooth Mesh Technology.
The technology includes Bluetooth 5 2Mbps for data transfer alongside Bluetooth Mesh, creating mesh networks within the wireless sensor market.
Thread: Why it's Needed
As Jorg Kennis and Jos Bruins from Germany's OSRAM company put it on the Thread Group blog: "Today's wide offering of IoT solutions often require that we set up and maintain a network for every protocol we want to use."
"It not only needs a lot of surveillance and maintenance to keep them up and running, but networks might also interfere with each other. Furthermore, since they are separate networks, devices do not "talk" to each other and there is no way to control them effectively from a single location, to monitor and analyze their data, or to provision them over various locations and users, in an end-to-end secure manner."
"This is where Thread comes in. Thread isn't yet another smart building protocol similar to those described above. Instead, it's like a Wi-Fi network, which is specifically designed for low-power, mesh IoT devices. Like Wi-Fi, it works with the Internet Protocol. And like Wi-Fi, it can run every modern IoT application that runs over IP."

PROCMAILRC(5) - Linux man page online | File formats
Procmail rcfile.
PROCMAILRC(5) File Formats Manual PROCMAILRC(5)
procmailrc - procmail rcfile
For a quick start, see NOTES at the end of the procmail(1) man page. The rcfile can contain a mixture of environment variable assignments (some of which have special meanings to procmail), and recipes. In their most simple appearance, the recipes are simply one line regular expressions that are searched for in the header of the arriv‐ ing mail. The first recipe that matches is used to determine where the mail has to go (usually a file). If processing falls off the end of the rcfile, procmail will deliver the mail to $DEFAULT. There are two kinds of recipes: delivering and non-delivering recipes. If a delivering recipe is found to match, procmail considers the mail (you guessed it) delivered and will cease processing the rcfile after having successfully executed the action line of the recipe. If a non-delivering recipe is found to match, processing of the rcfile will con‐ tinue after the action line of this recipe has been executed. Delivering recipes are those that cause header and/or body of the mail to be: written into a file, absorbed by a program or forwarded to a mailaddress. Non-delivering recipes are: those that cause the output of a program or filter to be cap‐ tured back by procmail or those that start a nesting block. You can tell procmail to treat a delivering recipe as if it were a non-delivering recipe by specifying the 'c' flag on such a recipe. This will make procmail generate a carbon copy of the mail by delivering it to this recipe, yet continue processing the rcfile. By using any number of recipes you can presort your mail extremely straightforward into several mailfolders. Bear in mind though that the mail can arrive concurrently in these mailfolders (if several procmail programs happen to run at the same time, not unlikely if a lot of mail arrives). To make sure this does not result in a mess, proper use of lock‐ files is highly recommended. The environment variable assignments and recipes can be freely intermixed in the rcfile. If any environment variable has a special meaning to procmail, it will be used appropri‐ ately the moment it is parsed (i.e., you can change the current directory whenever you want by specifying a new MAILDIR, switch lockfiles by specifying a new LOCKFILE, change the umask at any time, etc., the possibilities are endless :-). The assignments and substitutions of these environment variables are handled exactly like in sh(1) (that includes all possible quotes and escapes), with the added bonus that blanks around the '=' sign are ignored and that, if an environment variable appears without a trailing '=', it will be removed from the environment. Any program in backquotes started by procmail will have the entire mail at its stdin. Comments A word beginning with # and all the following characters up to a NEWLINE are ignored. This does not apply to condition lines, which cannot be commented. Recipes A line starting with ':' marks the beginning of a recipe. It has the following format: :0 [flags] [ : [locallockfile] ] Conditions start with a leading '*', everything after that character is passed on to the internal egrep literally, except for leading and trailing whitespace. These regular expressions are completely compatible to the normal egrep(1) extended regular expressions. See also Extended regular expressions. Conditions are anded; if there are no conditions the result will be true by default. Flags can be any of the following: H Egrep the header (default). B Egrep the body. D Tell the internal egrep to distinguish between upper and lower case (contrary to the default which is to ignore case). A This recipe will not be executed unless the conditions on the last preceding recipe (on the current block-nesting level) without the 'A' or 'a' flag matched as well. This allows you to chain actions that depend on a common condition. a Has the same meaning as the 'A' flag, with the additional condition that the immedi‐ ately preceding recipe must have been successfully completed before this recipe is executed. E This recipe only executes if the immediately preceding recipe was not executed. Exe‐ cution of this recipe also disables any immediately following recipes with the 'E' flag. This allows you to specify 'else if' actions. e This recipe only executes if the immediately preceding recipe failed (i.e., the action line was attempted, but resulted in an error). h Feed the header to the pipe, file or mail destination (default). b Feed the body to the pipe, file or mail destination (default). f Consider the pipe as a filter. c Generate a carbon copy of this mail. This only makes sense on delivering recipes. The only non-delivering recipe this flag has an effect on is on a nesting block, in order to generate a carbon copy this will clone the running procmail process (lock‐ files will not be inherited), whereby the clone will proceed as usual and the parent will jump across the block. w Wait for the filter or program to finish and check its exitcode (normally ignored); if the filter is unsuccessful, then the text will not have been filtered. W Has the same meaning as the 'w' flag, but will suppress any 'Program failure' mes‐ sage. i Ignore any write errors on this recipe (i.e., usually due to an early closed pipe). r Raw mode, do not try to ensure the mail ends with an empty line, write it out as is. There are some special conditions you can use that are not straight regular expressions. To select them, the condition must start with:! Invert the condition. $ Evaluate the remainder of this condition according to sh(1) substitution rules inside double quotes, skip leading whitespace, then reparse it.? Use the exitcode of the specified program. < Check if the total length of the mail is shorter than the specified (in decimal) num‐ ber of bytes. > Analogous to '<'. variablename?? Match the remainder of this condition against the value of this environment variable (which cannot be a pseudo variable). A special case is if variablename is equal to 'B', 'H', 'HB' or 'BH'; this merely overrides the default header/body search area defined by the initial flags on this recipe. \ To quote any of the above at the start of the line. Local lockfile If you put a second (trailing) ':' on the first recipe line, then procmail will use a locallockfile (for this recipe only). You can optionally specify the locallockfile to use; if you don't however, procmail will use the destination filename (or the filename following the first '>>') and will append $LOCKEXT to it. Recipe action line The action line can start with the following characters:! Forwards to all the specified mail addresses. | Starts the specified program, possibly in $SHELL if any of the characters $SHELL‐ METAS are spotted. You can optionally prepend this pipe symbol with variable=, which will cause stdout of the program to be captured in the environment variable (procmail will not terminate processing the rcfile at this point). If you specify just this pipe symbol, without any program, then procmail will pipe the mail to stdout. { Followed by at least one space, tab or newline will mark the start of a nesting block. Everything up till the next closing brace will depend on the conditions specified for this recipe. Unlimited nesting is permitted. The closing brace exists merely to delimit the block, it will not cause procmail to terminate in any way. If the end of a block is reached processing will continue as usual after the block. On a nesting block, the flags 'H' and 'B' only affect the conditions lead‐ ing up to the block, the flags 'h' and 'b' have no effect whatsoever. Anything else will be taken as a mailbox name (either a filename or a directory, absolute or relative to the current directory (see MAILDIR)). If it is a (possibly yet nonexis‐ tent) filename, the mail will be appended to it. If it is a directory, the mail will be delivered to a newly created, guaranteed to be unique file named $MSGPREFIX* in the specified directory. If the mailbox name ends in "/.", then this directory is presumed to be an MH folder; i.e., procmail will use the next number it finds available. If the mailbox name ends in "/", then this directory is pre‐ sumed to be a maildir folder; i.e., procmail will deliver the message to a file in a sub‐ directory named "tmp" and rename it to be inside a subdirectory named "new". If the mail‐ box is specified to be an MH folder or maildir folder, procmail will create the necessary directories if they don't exist, rather than treat the mailbox as a non-existent filename. When procmail is delivering to directories, you can specify multiple directories to deliver to (procmail will do so utilising hardlinks). Environment variable defaults LOGNAME, HOME and SHELL Your (the recipient's) defaults PATH $HOME/bin:/usr/local/bin:/usr/bin:/bin (Except during the processing of an /etc/procmailrc file, when it will be set to '/usr/local/bin :/usr/bin:/bin'.)

I'm trying to convert lower case t where ever it occurs to upper case t.
I'm getting an error though. Heres my code.
string1 = 'timbucktwo'
t = 't'
while t.islower in string1:
 print(string1, t.isupper())
What should I do?

What you're trying to do is fairly simple, and if you step back from the upper/lower-case issue it's just "replace 't' with 'T'". You can do this using:
string1.replace('t', 'T')
share|improve this answer

Let me try this again. :^) The loop won't execute because t.islower is the method, and 'x in some_string' requires x to be a string, and so a TypeError is raised. – DSM Mar 11 '12 at 22:58

Yep, I was being hasty and not thinking it through. Edited my answer to just ignore that, as your analysis is correct :) – James Aylett Mar 11 '12 at 23:00

You would need to set string1 each time equal to the string returned by 'replace'. Otherwise, if string1 originally contained a 't', it would loop infinitely. – TheDude Mar 13 '12 at 3:03
I think you should have:
string1 = 'timbucktwo'
while 't' in string1:
 string1 = string1.replace('t', "T")
 print(string1)

Semantic Methods for Security Policies and Trust Management "Security policies" are a common tool for defining the security behaviour of a complex system. Since such policies are often specified by disntinct parties, heterogeneous policies often have to be merged. As part of its involvement in the REWERSE Network of Excellence, the Information Systems Laboratory conducts research on the design and deployment of rule-based languages for specifying, composing and enforcing security policies. In additon, methods for validation of policies and change management are being studied. Related to this topic is our work on the Semantic Web, where security and trust are considered key issues.

There is a very good chart of the distintive badges used at Auschwitz in Danuta Czech "Auschwitz Chronicle" page 82. (Owl Books; 1989: ISBN 0-8050-0938-8 and -- pb --0-8050-5238-0. Gypsies were given a brown triangle pointed down. "Asocial" prisoners were given a black triangle pointed down as were "labor reeducation prisoners." The latter had a white "A" in the center of the triangle. Additionally "asocial Jews" wore a star of David with a a black triangle pointed down superimposed on a yellow triangle pointed up.
I am a 7th grade English teacher in.... We do study the holocaust as part of an interdisciplinary unit. I would appreciate any information you could give me about the triangles. Last year I had students who wanted to design a t-shirt using those symbols.
The chart in Danuta Czech's book should provide a good basis for the design of a t-shirt.
Thank you for your help. I have bookmarked your web site as a future reference for my students.
Thank you for the compliment. I hope this helps you. If your students decide to design a t-shirt, please let us know.

There is a dilemma for all tenants of a public or private cloud: Scope. Tenants want everything to be in scope. Cloud Service Providers (CSP) want to limit scope to the bare minimum. What does it mean for a Cloud to be 'PCI Compliant', and why is this a requirement for some tenants? The real issue is, what is in scope for PCI-DSS while your data is in the cloud, and how can you as the tenant meet those requirements? Remember, in the cloud, scope becomes a huge issue and a dilemma for the tenant, mainly because they may not know the scope of the cloud provider's audit and may never find it out. So what is this scope issue and can it be fixed?
There are a growing number of cloud services that will fall under the jurisdiction of PCI-DSS, from public cloud customer-facing web sites with order forms to cloud-based storage where those records, workloads, and other personal identifiable information (PII) is stored. So yes, PCI-DSS must include Data Protection (Virtualization Backup) as well as Cloud Computing and your local virtual or private cloud environment. PCI-DSS spans the entire spectrum of hybrid cloud security. Currently, others have claimed the following:
 - IaaS: The CSP is responsible for everything below the hypervisor including its own management processes, but the tenant is responsible for everything above the hardware.
 - SaaS: The CSP is responsible for everything through the app but not the tenant's data.
 - PaaS: The CSP is responsible for the 'stack' but not the final application and not the tenant's data.
 - Recovery as a Service (RaaS): The CSP is only responsible for its portal and the underlying disk infrastructure, and the tenant is responsible for the data.
There is a common thread throughout all these: the CSP is NOT responsible for customer data. But PCI-DSS is all about protecting the data, which implies that the tenant is responsible for all data needs.
The PCI-DSS Dilemma
The real issue here is, how is the PII data protected at rest, but also in motion? This implies that the CSP's hardware, which the data travels through (physical switches, storage fabrics, compute nodes), also comes into scope. But this is an area that the tenant cannot normally audit to ensure PCI-DSS is followed.
Yet, the CSP has done an audit, and it can be referenced. But this is misleading as the scope of that audit is the CSP's own handling of PII, and the tenant workloads are not necessarily considered PII (unless the cloud provider signs up to treat such data as PII). Given this, the scope of the CSP audit is much different than where the tenants data resides, runs, and moves around the environment.
However, we need to also consider End User Computing devices, which are used to access PII every day. Do these devices, and the wireless networks to which they are connected, fall into scope as well? What happens if these devices also connect to foreign (as in not approved) clouds? Do those connections now come into scope? PII traveling through AT&T or Verizon from my iPad would be encrypted, but you would have to prove such encryption if this was the modus operandi for the end users.
Concluding Thoughts
There are some interesting concepts around PCI-DSS audits that pertain to cloud services that include data protection, which makes me wonder if the audits for CSPs are scoped properly. I think not; I think PCI-DSS has to rule on this, but should treat all data in a cloud as being PII unless otherwise told. This way, we can properly rely on CSP audits of underlying levels. But I also think the new clouds for data protection are wide open and generally out of scope for current PCI-DSS audits; they should not be. What are your thoughts?

 As a user of the cloud I would always be interested in compliance against the standards. Since the data resides and moves on the cloud infrastructure, data points will be needed from cloud provider for audit purposes.
 Cloud service providers can think of providing data points ( preferably the violations ) based on analysis of the data for compliance to tenants as a service.
 2. April 18, 2013 at 5:47 AM
 Agreed, but only if they can provide corroborating logs on a per tenant basis. Unfortunately, some logs do not tag or separate by tenant.

In the cool winter months, it can be near impossible to keep skin hydrated.
Fortunately, there is an all-natural method that will help moisturise dry skin – and it requires no expensive beauty products.
According to a recent study into the benefits of houseplants commissioned by The Royal Horticultural Society (RHS) in collaboration with Reading University and PHD student Curtis Gubb, there are certain potted plants that are good for your skin.
The study found that certain flowers and shrubs can counteract the drying caused by heating units through a process called transpiration.
During transpiration, plants lose water through their leaves. When the process occurs with houseplants, the result is an increase in moisture in the air indoors.
Of the findings, Dr Tijana Blanusa, the chief horticultural scientist for the RHS, told The Telegraph: "House plants may be a simple and affordable way to reduce air dryness indoors and alleviate symptoms of dry skin, while providing multiple other benefits – for human psyche and physical health."
To choose the best plants for your skin, the researchers recommend those with high transpiration rates, as well as plants with large canopies that can expel more water.
"Depending on plant type, size, and condition within a room, plants can lose as much as several hundred ml of water per sq m of leaf area," Dr Blanusa said.
The most effective plants for the purpose are peace lilies, which can evaporate the equivalent of a "small teacup" of water a day, and ivy, according to the study – but Dr Blanusa said there are likely many other plants that would be beneficial in fighting the battle against dehydrated skin.
The horticulturist also discussed the other benefit of having plants in your home – clean, allergen-free air.
"Additionally, plants capture dust and particles from the indoor air, so again large leaf areas are good to provide this benefit," she said. "A number of chemical compounds such as those found in paints and furnishings, as well as gasses emitted in cooking and burning can be removed by houseplants."
However, the experts said more research was required to find out exactly how many plants are needed in a room to contribute to cleaner air.
Instead of splurging on moisturisers and lotions, you can purchase a potted peace lily, spider plants, or Areca palms to keep skin hydrated this winter.

The guide showed us the Sumita. The tower is very special and its architectural environment is very in line with the picture of the universe depicted in Buddhism. The tower also has many reliefs carved into it, which is lifelike. It can be said to be a national treasure class artifact.
The Zhengding Kaiyuan Temple's Xumi Tower, commonly known as the brick tower, is the main building of Kaiyuan Temple. It was built in the Tang Dynasty in the ten years of the Tang Dynasty (636), and is a nine-level densely-square-shaped tower with a square plane and a relief eight bodies in four corners. The first floor front door hinges on the upper end of the inlaid green beams, titled "Sumi Yongli" stone. The tower body is simple and simple, stable and dignified. Although the two generations of Jingming, Xiang's re-repair, still maintain the obvious Tang Tower style.
There are still quite a few points worth watching. In addition to the Sumi Tower, the bell tower here also has a tortoise-like stone next to it, which is also very historic. I really like the shape of the strong man under the Sumi Tower. It's still quite cold in winter.
There are four towers in the ancient city of Zhengding. Each tower is located in a different temple. Three towers are charged. The highest charge is on the Kaiyuan Temple. There are parking facilities at the door. People who come by are not special. Many.
[view] [interest] [price/performance] Beautiful ancient city
The shumita of kaiyuan temple is very special, it is worth seeing.
Kaiyuan Temple, located on the west side of Changsheng Street, Zhengding County, Hebei Province, was originally called Jingguan Temple. It was built in the second year of Xinghe in the Eastern Wei Dynasty. It was renamed Xiehui Temple in the tenth year of Emperor Kaihuang in the Sui Dynasty.
Although it has undergone maintenance, it still maintains the architectural characteristics of the Tang Dynasty. Xumi Pagoda is one of the "four towers" of Zhengding Ancient City and a precious heritage of my country's architectural treasure house.
Xumi Tower, also known as Wild Goose Pagoda, is located on the west side of the bell tower. The tower body is built on a square brick foundation. The tower plane is square, with nine levels of dense eaves. The first layer of the tower body is higher, and the lower stone steep slab is rounded. Both ends of the tower are embossed with a powerful statue of a strong man. All above the stone waistline is made of blue bricks. On the front, there is a stone coupon door, the door frame is carved with vases and flower patterns, and the door is embossed with two dragons and beads.
Xumi Pagoda, Kaiyuan Temple fell into disrepair for a long time, the remains of the temple abandoned. After the palace collapsed, a bell tower still remains. Tickets cost 10 yuan, which is the only one among the four towers of Zhengding. The square brick tower has nine levels of dense eaves. The lintel is embedded with the four characters "Xu Mi Qiao Li". Sumi is the Sanskrit word for Sumi Mountain, meaning Miao Gao. The tower gets its name. The tower is built on a square brick foundation, 42.5 meters high. A majestic statue of a powerful man is embossed on both sides of the bottom four corners of the tower, a total of eight. On the front, there is a stone coupon door, the door frame is carved with vases and flower patterns, and the door follows the relief of two dragons and beads.

Abstract: The early modern Portuguese empire presents a variety of case studies to explore the process of border making experienced in direct response to European activity and imperialism. Considering its scale and dispersion, the Portuguese empire shows both fluidity and rigidity of borders and the strategies of control and security taken in response to or within their establishments. The Portuguese factory of São Jorge da Mina, that was built in 1482, and Macao, one of the most important European harbours in Asia in the 1550s, offer valuable insights into early Portuguese/non-European relations. Both cases constitute a concession of a limited and well-defined land where the Portuguese could stay, with full control, resulting from agreement with the terms stipulated by the local authorities. Considering the asymmetries of historiography when treating the two cases, rather than a direct comparison, this article aims to bring some reflections on these experiences as paradigms of the limit of action of the early modern Portuguese empire.
Keywords: Portuguese empire, governance, port cities, early modern history, sovereignty.

std.variant.Algebraic may be, depending on allowed types
Customizing marshaling of struct types
Marshaling behavior can be changed for a struct type by adding the @dbusMarshaling UDA with the appropriate flag. The following flags are supported:
 - includePrivateFields enables marshaling of private fields
 - manualOnly disables marshaling of all fields
Marshaling of individual fields can be enabled or disabled by setting the DBusMarshal flag as an UDA. I.e. @Yes.DBusMarshal or @No.DBusMarshal.
Note: symbols Yes and No are defined in std.typecons.
After converting a DBus structure to a D struct, any fields that are not marshaled will appear freshly initialized. This is true even when just converting a struct to DBusAny and back.
import ddbus.attributes;
import std.typecons;
@dbusMarshaling(MarshalingFlag.includePrivateFields)
struct WeirdThing {
 int a; // marshaled (default behavior not overridden)
 @No.DBusMarshal int b; // explicitly not marshaled
 private int c; // marshaled, because of includePrivateFields
}
Modules
 - attributes: defines some UDAs (and related templates) that can be used to customize struct marshaling.
 - bus: bus functionality like requesting names and event loops.
 - conv: low level type marshaling methods.
 - exception: exception classes
 - router: message and signal routing based on MessagePattern structs.
 - simple: simpler wrappers around other functionality.
 - thin: thin wrapper types
 - util: templates for working with D type marshaling like canDBus!T.
 - c_lib: a D translation of the DBus C headers (you generally should not need to use these directly).
Importing ddbus will publicly import the thin, router, bus, simple and attributes modules. These provide most of the functionality you probably want, you can import the others if you want lower level control.
Nothing is hidden so if ddbus doesn't provide something, you can always import c_lib and use the pointers contained in the thin wrapper structs to do it yourself.
Concurrent Updates
If you want to use the DBus connection concurrently with some other features or library like a GUI or vibe.d you can do so by placing this code in the update/main loop:
// initialize Connection conn; somewhere
// on update:
if (!conn.tick)
 return;
Or in vibe.d:
runTask({
 import vibe.core.core : yield;
 while (conn.tick)
 yield(); // Or sleep(1.msecs);
});
It would be better to watch a file descriptor asynchronously in the event loop instead of checking on a timer, but that hasn't been implemented yet, see Todo.
Todo
ddbus should be complete for everyday use but is missing some fanciness that it easily could and should have:
 - Support for adding file descriptors to event loops like vibe.d so that it only wakes up when messages arrive and not on a timer.
 - Marshaling of file descriptor objects
 - Better efficiency in some places, particularly the object wrapping allocates tons of delegates for every method.
Pull requests are welcome, the codebase is pretty small and other than the template metaprogramming for type marshaling is fairly straightforward.

We provide resources to assist our stakeholders in understanding our regulatory role and how we protect the public interest.
As part of its regulatory mandate, PEO establishes, maintains and develops: standards of knowledge and skill; standards of practice for the profession; standards of professional ethics; and promotes public awareness of its role. The following are resources to assist PEO stakeholders--licence holders, applicants, and the public--in understanding their roles and responsibilities and the regulator's work protecting the public interest.
Frequently Asked Questions
Does PEO accept continuing knowledge activities completed in another province or with another regulator?
Does PEO assist licence holders who find the knowledge declaration challenging?
PEO provides resources to assist licence holders, including guidelines and information sessions.
Does PEO accredit continuing knowledge activities courses to ensure they have value?
No. The value of a course depends on the needs of each licence holder. It is up to licence holders to develop a continuing knowledge plan of value to them.
Does attending manufacturer's workshops and training sessions on their new products or technologies count as continuing knowledge activities?
Yes, if the workshop training session deals with any of the core competencies given above.
Can attending a PEO chapter event count towards my continuing knowledge hours?
Yes. The program recognizes continuing knowledge activities that are learning sessions with technical knowledge and focus on maintaining or enhancing engineering competence. PEO provides guidance on the three types of continuing knowledge activities that are recognized by the PEAK program.
PEO does not validate specific continuing knowledge activities or endorse activity providers as being eligible for the PEAK program. Practising licence holders are asked to determine their own needs based on their practice and pursue relevant continuing knowledge opportunities, then report these activity hours to PEO using the online reporting tool in their Member Portal account.
Does PEO recognize online courses?
Yes. PEO is not concerned with how an individual learns but, rather, with what they learn. Any course that has content addressing at least one of the five core engineering competencies is acceptable. The core competencies are:
- A – Apply engineering knowledge, methods and techniques
- B – Use engineering tools, equipment or technology
- C – Awareness of the risks and impacts of engineering work
- D – Manage engineering activities
- E – Communicate engineering information
Over what timeframe should I be completing my recommended number of continuing knowledge activity hours to report back to PEO?
Practising licence holders are to asked to pursue continuing knowledge activities that occur during your licence period—from the date of your current licence renewal to shortly before your next renewal date the following year.
How do I determine how many or what continuing knowledge activities I should complete?
A truly unique aspect of the PEAK program is that it allows professional engineers the opportunity to design their own knowledge plan to align with their area of practice and the available continuing knowledge opportunities. Under this self-directed initiative, each licence holder will:
- complete the practice evaluation questionnaire to determine the recommended number of hours for annual supplemental knowledge (maximum of 30 hours annually);
- determine his or her own needs, based on his or her own practice;
- pursue opportunities that are most relevant to his or her practice; and
- report what they have done to PEO.
What is an acceptable continuing knowledge activity?
Acceptable continuing knowledge activities fall into three broad categories: formal education, informal education and contribution to knowledge.
Formal education refers to any structured classroom-based learning provided by persons with expert knowledge of the subject matter. This includes college or university courses in technical subjects; courses for industrial sector certifications; training courses provided by manufacturers or suppliers; and similar activities. Courses must be completed in order to count towards the annual continuing knowledge requirement. Teaching or instructing such courses also counts.
Informal education refers to learning activities that take place outside the classroom. This includes self-study through reading of technical journals, books or manuals. It also includes attendance at conference technical sessions or trade-shows; or at standalone workshops or seminars. Structured discussions with peers such as mentoring sessions or study groups are also acceptable as long as the subject of the discussions is technical in nature.
Contributions to knowledge includes any activity that disseminates knowledge to other licence holders or establishes best practices for the profession. This includes the preparation and publication of papers on topics of interest to the engineering community; preparation and publication of articles in technical or trade journals or magazines; participation on committees developing codes and standards; participation on expert advisory panels; preparing and/or delivering a seminar or presentation to an audience of professional engineers, technologists, or related professions.
Is the ethics module a test I need to prepare for?
The ethics module is not a test and requires no study or preparation before completing it. It is an interactive video refresher to help both practising and non-practising licence holders get reacquainted with their ethical and professional obligations as described in the Professional Engineers Act (PEO's regulatory role; legal and ethical obligations of licensure; professional misconduct; and a licence holder's duty to report). You'll also be reminded on how these obligations should be applied in real-life situations.

Image analysis is an interesting research area in both graphics and in computer architecture. In this paper, the authors have done detailed analysis on image for designing an efficient way of storing and comparing images within a device. Especially, when the device is an embedded system it needs much care in processing information stored in that device. The important factors that must be considered for any given application include performance, reliability and cost. Any computer that handles large amount of graphical information, involving pictorial images and animation, must have good real time performance.

Efficient Static Compaction Techniques for Sequential Circuits Based on Reverse Order Restoration and Test Relaxation.
At Asian Test Symposium
In this paper we present efficient Reverse Order Restoration (ROR) based static test compaction techniques for synchronous sequential circuits. Unlike previous ROR techniques that rely on vector-by-vector fault-simulation based restoration of test subsequences, our technique restores test sequences based on efficient test relaxation. The restored test subsequence can be either concatenated to the compacted test sequence, as in previous approaches, or merged with it. Furthermore, it allows the removal of redundant vectors from the restored subsequences using State Traversal technique and incorporates schemes for increasing the fault coverage of restored test subsequences to achieve an overall higher level of compaction. In addition, test relaxation is used to take ROR out of saturation. Experimental results demonstrate the effectiveness of the proposed techniques.

Are all trades stored in block chain?
Are all trades, like mtgox exchange, gambling, etc. stored in block chain? Or, few trades could have been skipped / ignored?
Consider this case, 'a' transfers 10btc to 'b', and then 'b' transfers 10btc to 'c'. Is it possible to store this as single trade, as 'a' transfers 10btc to 'c'?
Is it possible for an exchange to include fake bid/ask orders for it's own benefit?
Is it really possible to differentiate between two transfers, where in one transfer is between single user accounts and another one is between two users?
Within an exchange's ledger system, value may be moved between accounts without creating actual transactions in the public Bitcoin ledger, the blockchain. Exchanges that use this method keep all of their reserves in one set of accounts and simply debit and credit user accounts as necessary. Only when a Bitcoin transaction is necessary to move value from one account to another outside of the system will a Bitcoin transaction be created and broadcast.
In other systems, an exchange or other entity may actually create a new Bitcoin transaction for every trade. This method is more inline with the ideals of Bitcoin, but costs more because of the transaction fees necessary to expedite/facilitate processing.
Any transaction stored in the Block Chain are money transfers between two Addresses. However, if one controls both of the Addresses in question and runs some accounting system on top of the Address balances (such as bitcoind and the use of Accounts), one does not need to create Transactions in order to move bitcoins between two accounts. They can just update their personal ledger of the different Accounts. This option creates less noise in the Block Chain and makes the money transfers instantaneous, but requires extra effort to make sure each Account can only spend only the bitcoins they own.
Many systems can and do behave like this. I'm guessing all of the exchanges do this, as well as some eWallets and probably some casinos.

As customer demands grow more exacting, businesses need to cater to their needs quickly. The continuous increase in customers and road traffic can hamper the smooth delivery of products and services.
Route planning apps like Roadwarrior enable businesses to take advantage of their software and eliminate their worries about slow and hassle deliveries. Smart route optimization apps can take the weight off your shoulder by giving you efficient solutions guaranteed to benefit your employees and customers.
Here are some reasons why you should invest in a route planning app for your business:
1.Decreases distance and fuel expenses
These apps can automatically and quickly calculate the routes that your delivery vehicles will take to decrease the distance that needs to be driven. Doing this will also lessen the fuel costs. Make sure to utilize a good route planning app that can assure you of this benefit.
In addition to that, your vehicles will have reduced carbon emissions since they use less fuel than others. The shorter the travel distance, the lower the fuel usage, and the lesser they will contribute to emitting carbon. Using route planning apps is also another way to be eco-friendly.
2.Saves travel time
Since the app can calculate the distances that the vehicle will travel, your employees can save time planning which routes they will take. This way, you're also protecting your employees, especially delivery drivers, from getting lost and overfatigue.
Most software has algorithms that compare different travel times depending on the mode of transport too. Instead of relying on your employee's stock knowledge about routes and stressing them about planning their delivery routes, you can just leave the job to route planning apps. With this, you can also expect more deliveries completed within the day.
3.Ensures customer and employee satisfaction
Route planning apps can give you estimates of how long you will travel. This can give your customers a heads up on which day or what time their orders will come so they can coordinate with you whenever they are not available to receive them.
For employees, you will be able to distribute the workload among the drivers appropriately. This will eliminate inequality in travel times and distances that might spur some problems between the employees and you. The planning apps can solve a lot of hassles related to the delivery of products or services.
4.It helps create stronger delivery strategies.
Route optimization software allows you to do simulations to help make better decisions regarding delivering your products or services. It is advantageous to operational planning and your overall delivery system by calculating the travel time and distance of various vehicles to determine the most efficient option and compare the best delivery times.
Route planners have prevailed due to GPS and the Internet. As a business, you must take advantage of these innovations to upgrade your company's services. Not only will these apps give your employees less hassle, but they can also ensure further customer satisfaction. The faster you can provide services and products to them, the more they will like and trust you.

This page explains how to use audit logging in your Kubernetes Engine clusters.
All Kubernetes-powered clusters have Kubernetes Audit Logging, which keeps a chronological record of all calls that have been made to the Kubernetes API server in that cluster. These logs are useful for investigating suspicious API requests, for collecting statistics, or for creating monitoring alerts for unwanted API calls.
Kubernetes Engine clusters integrate Kubernetes Audit Logging with Cloud Audit Logging on Google Cloud Platform, which lets you access the audit log information through Stackdriver Logging. The most important audit logs are exported automatically at no charge. If you need to audit all requests to your cluster's Kubernetes API server, you must enable Data Access logs for Kubernetes Engine in Cloud Audit Logging.
Before you begin
- Ensure you have an active cluster.
- Read about Kubernetes Audit Logging.
Accessing Audit Logs
You can locate and view your cluster's audit logs by using Google Cloud Platform Console
or by using the
gcloud command-line tool.
To view audit logs for your cluster, perform the following steps:
In the GCP Console, navigate to Logging.
Select the Logs view.
- From the drop-down menu, select Kubernetes Cluster and your cluster name.
You can view audit log records about specific resources by using the
logging read command in the
For example, to view audit log records about Deployment resources created on your cluster, use the following command:
gcloud logging read'resource.type="k8s_cluster" AND protoPayload.methodName:"deployments.create"'
Stackdriver log entries are associated with monitored resource and service
types. For Kubernetes Engine audit
logs, the resource type is
Kubernetes Cluster, defined by a
Audit logs are structured objects consisting of an
operation subobject and a
operation specifies a request that the audit log event
belongs to, and the
protoPayload contains the audit log entry itself,
response objects (if applicable).
Once you've accessed your audit logs, you can use Stackdriver's filtering syntax to find the relevant logs you want. Some useful filters include:
To display all requests with failed authorization:
To display all write requests to a Secret resource:
resource.type="k8s_cluster" protoPayload.methodName:"io.k8s.core.v1.secrets" NOT protoPayload.methodName:"get" NOT protoPayload.methodName:"list" NOT protoPayload.methodName:"watch"
To display all requests to a Pod resource from a particular user:
resource.type="k8s_cluster" protoPayload.methodName:"io.k8s.core.v1.pods" protoPayload.authenticationInfo.principalEmail="_EMAIL_"
Other Stackdriver Features
You can use any of Stackdriver's logging features to perform common and useful tasks with your Kubernetes Engine cluster's audit logs. These might include:
- Setting up a log metric for a given filter
- Creating a Stackdriver alert policy based on a log metric
- Export your cluster's audit logs to a service such as Cloud Storage, BigQuery, or Cloud Pub/Sub.
The Kubernetes audit policy determines what audit log data is exported from the Kubernetes API server.
For read requests such as
watch, only the request object is
saved in the audit logs; the response object is not. For requests involving
sensitive data such as
ConfigMap, only the metadata is exported.
For all other requests, both request and response objects are saved in audit
Kubernetes omits certain high-volume calls made by system services. For complete information on which calls the Kubernetes audit policy includes or omits from the logs, see the latest audit policy configuration in the open-source Kubernetes repository.

So you're in the market for some pickups. You pull up Google and start looking. So many options, so many builders. This one says it has AlNiCo III magnets, this other one says AlNiCo V and yet another says it's loaded with AlNiCo II. What does this mean and what is the difference, really?
Let's start with what the word AlNiCo even means. AlNiCo is an acronym for a metal blend of aluminum, nickel, cobalt, and iron. The number following AlNiCo represents the proportions of each metal in that blend. For example, AlNiCo V contains 8% aluminum(al), 14% nickel(ni), 24% cobalt(co), 3% copper(not included in AlNiCo acronym), and the balance (51%) is iron. AlNiCo III, and II use different proportions to achieve different magnet strengths and properties.
AlNiCo magnets were invented in the 1920's as an alternative to weaker Iron magnets. Iron magnets weakened quickly and lost charge easily with shock or temperature changes. Alnico magnets keep a stronger magnetic field over time and are more resilient to shock and heat.
The most popular AlNiCo magnets you will see in guitar and bass pickups are AlNiCo V, AlNiCo II, AlNiCo III, AlNiCo IV, and AlNiCo VIII. Most commonly you will see AlNiCo V and ceramic (which is a different animal and found in many modern, more aggresive pickups).
Leo Fender started using AlNiCo blended magnets in his experimental pickups as early as 1940. In the Blackguard Book, Nacho Baños writes that Leo used AlNiCo III in the early Broadcasters and Teles. Early P.A.F. humbuckers used AlNiCo V or II. Often, builders used what was available at the time and they changed every few years. Fender was notorious for this.
When shopping for vintage style pickups, you will see alnico II referenced often. This blend is used by many pickup makers for vintage reissue pickups. It is similar to AlNiCo III in that it is weaker than the AlNiCo V we hear so often, but the composition and resulting tone is very different.
Alnico V is by far the most used magnet in our shop with 95% of all pickups produced here using that blend. AlNiCo V has a stronger magnetic pull than AlNiCo II or III. This translates into tighter low end response and a more aggressive, edgy tone.
A good way to imagine the difference between Alnico magnets is to compare them to shocks in a car. Alnico II is like a set of worn in shocks, Alnico V is more like a set of stiff shocks, and Neodymium is like a hardtail Harley, translating every bump in the road.
So what do I use?
There are a few considerations here:

- LUX METER
- EXPOSURE METER
- FLASH METER
- SPOT METER
- COLOR METER
- FLICKER METER
As a luxmeter you can measure illuminance (density of luminous flux incident on a surface) from 0.1 to _PHONE_ lx.
By using the app in "exposure meter" mode you get an easy to use incident/reflected light meter and you can determine the proper exposure for a photograph.
LxMeter supports measurements of flash lights and can trigger a flash using the Bluetooth connection of your smartphone.
During flash mode the app can display the percentage of flash in total exposure.
LxMeter can also deal with landscapes or other distant objects by running its spot meter mode; you can measure luminance (cd/m2 or foot-lambert) and correlated color temperature (CCT).
A powerful analysis tools has been added to LxMeter in order to evaluate flicker performance of a light source according to IEEE 1789. You can detect harmonics up to 30kHz, display the frequency spectrum and get all the parameters commonly found in professional flicker-meters.
You can specify ISO speed and exposure time and let the app show in real time the optimal aperture value or set the aperture and read the exposure time.
You can easily switch between shutter speed priority and aperture priority or just run the manual mode and take note of the exposure level indicator.
LxMeter allows you to add some notes to your personal archive. Exposure and location information will be added automatically. You can save all the notes about a photographic project in the internal archive and use them as reference later at the time of the final shots.
Please, note that for maximum performance this app requires an external sensor of the SS04 product line. As alternative you can use the internal light sensor of your phone (if it has one) but in this case the accuracy of measurements will vary depending on the phone.

 $ oc adm release mirror -a ${LOCAL_SECRET_JSON} --to-dir=${REMOVABLE_MEDIA_PATH}/mirror quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE} --dry-run
 4. Mirror the version images to the mirror registry.
 - If your mirror host does not have internet access, take the following actions:
 1. Connect the removable media to a system that is connected to the internet.
 2. Mirror the images and configuration manifests to a directory on the removable media:
 $ oc adm release mirror -a ${LOCAL_SECRET_JSON} --to-dir=${REMOVABLE_MEDIA_PATH}/mirror quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE}
 3. Take the media to the restricted network environment and upload the images to the local container registry.
 $ oc image mirror -a ${LOCAL_SECRET_JSON} --from-dir=${REMOVABLE_MEDIA_PATH}/mirror "file://openshift/release:${OCP_RELEASE}*" ${LOCAL_REGISTRY}/${LOCAL_REPOSITORY} 1
 1
 For REMOVABLE_MEDIA_PATH, you must use the same path that you specified when you mirrored the images.
 4. Use oc command-line interface (CLI) to log in to the cluster that you are upgrading.
 5. Apply the mirrored release image signature config map to the connected cluster:
 $ oc apply -f ${REMOVABLE_MEDIA_PATH}/mirror/config/<image_signature_file> 1
 1
 For <image_signature_file>, specify the path and name of the file, for example, signature-sha256-81154f5c03294534.yaml.
 - If the local container registry and the cluster are connected to the mirror host, directly push the release images to the local registry and apply the config map to the cluster by using following command:
 $ oc adm release mirror -a ${LOCAL_SECRET_JSON} --from=quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE} \
 --to=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY} --apply-release-image-signature
 Note
 If you include the --apply-release-image-signature option, do not create the config map for image signature verification.
8.5. Creating the image signature config map
Before you update your cluster, you must manually create a config map that contains the signatures of the release images that you use. This signature allows the Cluster Version Operator (CVO) to verify that the release images have not been modified by comparing the expected and actual image signatures.
If you are upgrading from version 4.4.8 or later, you can use the oc CLI to create the config map. If you are upgrading from an earlier version, you must use the manual method.
8.5.1. Creating an image signature config map manually
Create and apply the image signature config map to the cluster that you want to update.
Note
You must perform following steps each time that you update a cluster.
Procedure
 1. Review the OpenShift Container Platform update paths knowledge base article to determine a valid update path for your cluster.
 2. Add the version to the OCP_RELEASE_NUMBER environment variable:
 $ OCP_RELEASE_NUMBER=<release_version> 1
 1
 For <release_version>, specify the tag that corresponds to the version of OpenShift Container Platform you want to update the cluster, such as 4.4.0.
 3. Add the system architecture for your cluster to ARCHITECTURE environment variable:
 $ ARCHITECTURE=<server_architecture> 1
 1
 For server_architecture, specify the architecture of the server, such as x86_64.
 4. Get the release image digest from Quay:
 $ DIGEST="$(oc adm release info _URL_-release-dev/ocp-release:${OCP_RELEASE_NUMBER}-${ARCHITECTURE} | sed -n 's/Pull From: .*@//p')"
 5. Set the digest algorithm:
 $ DIGEST_ALGO="${DIGEST%%:*}"
 6. Set the digest signature:
 $ DIGEST_ENCODED="${DIGEST#*:}"
 7. Get the image signature from mirror.openshift.com website.
 $ SIGNATURE_BASE64=$(curl -s "_URL_ | base64 -w0 && echo)
 8. Create the config map:
 $ cat >checksum-${OCP_RELEASE_NUMBER}.yaml <<EOF
 apiVersion: v1
 kind: ConfigMap
 metadata:
 name: release-image-${OCP_RELEASE_NUMBER}
 namespace: openshift-config-managed
 labels:
 _URL_-signatures: ""
 binaryData:
 ${DIGEST_ALGO}-${DIGEST_ENCODED}: ${SIGNATURE_BASE64}
 EOF
 9. Apply the config map to the cluster to update:
 $ oc apply -f checksum-${OCP_RELEASE_NUMBER}.yaml
8.6. Upgrading the restricted network cluster
Update the restricted network cluster to the OpenShift Container Platform version that you downloaded the release images for.
Note
If you have a local OpenShift Update Service, you can update by using the connected web console or CLI instructions instead of this procedure.
Prerequisites
 - You mirrored the images for the new release to your registry.
 - You applied the release image signature ConfigMap for the new release to your cluster.
 - You obtained the sha256 sum value for the release from the image signature ConfigMap.
 - Install the OpenShift CLI (oc), version 4.4.8 or later.
Procedure
 - Update the cluster:
 $ oc adm upgrade --allow-explicit-upgrade --to-image ${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}<sha256_sum_value> 1
 1
 The <sha256_sum_value> value is the sha256 sum value for the release from the image signature ConfigMap, for example, @sha256:81154f5c03294534e1eaf0319bef7a601134f891689ccede5d705ef659aa8c92
 If you use an ImageContentSourcePolicy for the mirror registry, you can use the canonical registry name instead of LOCAL_REGISTRY.
 Note
 You can only configure global pull secrets for clusters that have an ImageContentSourcePolicy object. You cannot add a pull secret to a project.
8.7. Configuring image registry repository mirroring
Setting up container registry repository mirroring enables you to do the following:
 - Configure your OpenShift Container Platform cluster to redirect requests to pull images from a repository on a source image registry and have it resolved by a repository on a mirrored image registry.
 - Identify multiple mirrored repositories for each target repository, to make sure that if one mirror is down, another can be used.
The attributes of repository mirroring in OpenShift Container Platform include:
 - Image pulls are resilient to registry downtimes.
 - Clusters in restricted networks can pull images from critical locations, such as quay.io, and have registries behind a company firewall provide the requested images.
 - A particular order of registries is tried when an image pull request is made, with the permanent registry typically being the last one tried.
 - The mirror information you enter is added to the /etc/containers/registries.conf file on every node in the OpenShift Container Platform cluster.
 - When a node makes a request for an image from the source repository, it tries each mirrored repository in turn until it finds the requested content. If all mirrors fail, the cluster tries the source repository. If successful, the image is pulled to the node.
Setting up repository mirroring can be done in the following ways:
 - At OpenShift Container Platform installation:
 By pulling container images needed by OpenShift Container Platform and then bringing those images behind your company's firewall, you can install OpenShift Container Platform into a datacenter that is in a restricted network.
 - After OpenShift Container Platform installation

Measuring strategies for smooth tool steel surfaces
Paper i proceeding, 2008
Comparisons between different measuring strategies were made on three types of smooth tool steel surfaces. Three replica materials were tested to study possibilities within replication techniques. An optical interferometer as well as a mechanical stylus was used to evaluate the surfaces. The results showed that the tested replica materials generated good representations of both the form and the surface roughness (Sq > 300 nm). The evaluated surfaces were quite homogeneous, thus, few measurements are needed to get representative results. However, it was found that caution must be taken regarding manually polished surfaces which can be less homogenous and therefore require more measurements to get representative results.

Strawberry shortcake is a beloved dessert that has become a summertime staple in the United States. It is a mouthwatering treat that combines the sweetness of fresh strawberries with the fluffiness of a homemade cake and the richness of whipped cream. This delightful dessert is not only visually appealing but also irresistibly delicious, making it a favorite among people of all ages.
What is Strawberry Shortcake?
Strawberry shortcake is a classic dessert that consists of three main components: the biscuit-like shortcake, fresh strawberries, and whipped cream. The shortcake is a tender, crumbly, and slightly sweet cake that forms the base of the dessert. It provides a sturdy foundation for the juicy and vibrant strawberries that are typically sliced and mixed with a touch of sugar to enhance their natural sweetness. The final component is a dollop of fluffy whipped cream, adding a creamy and light element to the dessert.
The combination of these elements creates a harmonious balance of flavors and textures. The sweet and slightly tangy strawberries complement the buttery richness of the shortcake, while the airy whipped cream adds a delightful smoothness to each bite. This classic dessert is often served during summer gatherings, picnics, and barbecues, as it showcases the fresh and abundant strawberries that are typically available during this season.
Preparing strawberry shortcake is relatively simple and can be done in just a few steps. To begin, you will need to gather the ingredients for the shortcake, which include flour, sugar, butter, baking powder, salt, milk, and vanilla extract. The dough is then mixed and shaped into individual biscuits that are baked until golden brown.
In the meantime, the strawberries can be prepared by washing, hulling, and slicing them. A sprinkle of sugar can be added to enhance their natural sweetness and macerate the berries, resulting in a juicy and syrupy texture. The whipped cream is made by whipping heavy cream, sugar, and vanilla extract until soft peaks form.
Once all the components are ready, it's time to assemble the strawberry shortcakes. Split each biscuit in half horizontally, creating a top and a bottom. Spoon a generous amount of strawberries onto the bottom half, allowing the syrup to soak into the cake. Top it off with a dollop of whipped cream and place the other biscuit half on top. Serve immediately, and for an extra touch, you can garnish with a fresh strawberry or a drizzle of chocolate sauce.
With a preparation time of around 30 minutes, cooking time of 15-20 minutes for the biscuits, and servings that can vary depending on the size of the biscuits, strawberry shortcake is a versatile dessert that can be easily adjusted to accommodate a small or large gathering. It is best enjoyed fresh, while the biscuits are still warm and the strawberries are at their juiciest. This delightful dessert is perfect for enjoying with friends and family on a warm summer day, and it will surely leave everyone craving for more.
History of Strawberry Shortcake
Strawberry shortcake, a beloved classic dessert, has a long and fascinating history that dates back centuries. This delightful treat has evolved and transformed over time, becoming a staple in many cultures around the world.
The earliest known references to strawberry shortcake can be traced back to the 16th century. During this time, English and European settlers brought their love for sweets and pastries to the United States. Strawberry shortcake quickly gained popularity, especially during the summer months when fresh strawberries were abundant.
One of the earliest recorded mentions of strawberry shortcake is found in an English cookbook dating back to the 1580s. This cookbook describes a simple recipe consisting of a sweet biscuit-like cake, topped with fresh strawberries and cream. The combination of the buttery cake, juicy strawberries, and luscious cream was an instant hit.
Over the years, strawberry shortcake became deeply ingrained in American culture. It became a traditional dessert served during summer picnics, backyard barbecues, and Fourth of July celebrations. Families and friends would gather to share this delectable treat while enjoying the warm weather and bountiful harvest of strawberries.
Today, strawberry shortcake continues to be a beloved dessert in the United States. While the basic recipe remains the same, there are countless variations and adaptations. Some prefer to use sponge cake or angel food cake instead of the traditional biscuit, while others experiment with different fillings or toppings. Regardless of the variations, the essence of strawberry shortcake remains the same – a delightful combination of juicy strawberries, fluffy cake, and creamy goodness.
Whether you enjoy it at a fancy restaurant or make it at home for a casual get-together, strawberry shortcake is a dessert that brings joy and nostalgia to anyone who takes a bite.

Popularity and Traditions
Strawberry shortcake, with its delightful combination of sweet strawberries, fluffy cake, and whipped cream, has stood the test of time and remains a beloved dessert. The enduring popularity of strawberry shortcake can be attributed to both its delicious taste and the traditions that surround it.
One of the reasons why strawberry shortcake has become a staple dessert is its association with summertime. As the temperatures rise and people gather for backyard barbecues and picnics, the juicy, red strawberries are at their peak. The refreshing sweetness of this dessert makes it an ideal treat to enjoy during hot summer days.
Furthermore, strawberry shortcake has become synonymous with special occasions. Whether it's a birthday party, a family gathering, or a holiday celebration, strawberry shortcake is often the star of dessert tables. The vibrant red color of the strawberries adds a festive touch to any spread, making it a popular choice for festive occasions.
