Performance optimizations are not free. They ALWAYS come with a cost but do NOT always come with a benefit to offset that cost.

Even having useCallback() returning the same function instance, it doesn’t bring any benefits because the optimization costs more than not having the optimization.

We need to teach youth to fish for mentors and we need to stock the pond with more mentors.

This model is the most flexible and open-ended of the four; your goal as an instructor is not to design a full-fledged semester of material, activities, and assessments. Rather, your goal is to work with your class to design and become a learning community, working collaboratively and individually towards your determined learning goals. For this to work you should have: a set of possible/preferred learning objectives for your classa library of course materials, preferably with as much as possible in digital formata suggested list of digital tools and technologies that you’re comfortable from with a list of possible assignment/project/assessment ideas that are related to your learning objectivesa willingness to experiment and invite your students into the teaching & learning process. At the onset of class you will need to facilitate a conversation among you and your students about how the class will unfold. This can be done in small groups f2f, via an online communication tool, or in a hybrid mix of both. As a community you should plan on addressing the following: what are our objectives as a learning community? what kind of work could we engage in to meet these objectives? what physical/virtual spaces would we like to work in? how/when do we want to meet in these spaces?how do we want to measure (assess) if an objective has been met?what rules and policies should govern our work? how will we work virtually and respect everyone’s boundaries and personal situations? how will we work f2f and respect public health recommendations and personal situations? You will probably need to spend at least the first 1-2 weeks answering these questions together and then designing a plan for your course. Make sure you and your students talk through various complications: what if the university’s policies about meeting f2f change? what if classes are forced to move entirely virtual/remote? what someone (students or professor!) gets sick?

Finally, these are NOT meant to be comprehensive. Instead, imagine these models along a continuum of opportunity. Your challenge is to determine where your courses could fit between and among the proposals.  

While the modifying version will occasionally be useful, in general, we should gently push people towards using non-modifying code.

Some may say that copied/not-copied goes without saying. I agree with Tallyrand: "If it goes without saying, it goes all the better for saying it."

So when Avdi took to air some of those grievances on Twitter, the natural thing happened that always happens when you feel your work is attacked: The core contributor group got defensive! That’s a mischaracterization! Where are the completed bug reports!? You know the drill, if you’ve ever worked on something, poured your heart into it, and then seen it criticized online. There’s that immediate, knee-jerk reaction of a sting. But it doesn’t have to sting.

Prefactoring is the application of experience to the creation of new software systems. Its relationship to its namesake refactoring is that lessons learned from refactoring are part of that experience.

Prismatic gets a percentage of the revenue increase that it generates for publishers, while developers pay a flat monthly fee based on usage, Cross says. It’s still working out pricing for hedge fund API usage. (As a point of comparison, the revenue model for the old Prismatic was the same as the current model for publishers. “We just meant for it to be more like Adsense/Adwords where we ran all this in our own consumer products too,” Cross notes.)

amplification hypothesis, conversely, does not predict a unified conflict 341 detection axis in the population. Instead, it makes a prediction that is exactly contrary to 342 the epiphenomenal view: that conflict should shift population activity along task-variable 343 coding dimensions, but in the opposite direction. That is, conflict is predicted to amplify 344 task-relevant neural responses

At the population level, then, the epiphenomenon hypothesis330 predicts that conflict should decrease the amount of information about the correct response 331 and shift neuronal population activity down along the axis in firing rate space that encodes 332 this response

Neurons that were tuned for a specific correct response were 298 often tuned to prefer the same Simon/Ericksen distractor response

neurons did not encode the distractor response

Furthermore, the population of cells whose responses were significantly 244 affected by Eriksen conflict was almost entirely non-overlapping with the population 245 significantly affected by Simon conflict (specifically, only one cell was significantly 246 modulated by both)

As an engineer, it’s important to explore different technologies. It’s important to identify the tools available to tackle problems. And it’s important to expand your horizons because then you can look cool on your CV.

Some large tech behemoths could hypothetically shoulder the enormous financial burden of handling hundreds of new lawsuits if they suddenly became responsible for the random things their users say, but it would not be possible for a small nonprofit like Signal to continue to operate within the United States. Tech companies and organizations may be forced to relocate, and new startups may choose to begin in other countries instead.

e present a protocol for secure online com-munication, called “off-the-record messaging”, which hasproperties better-suited for casual conversation than do sys-tems like PGP or S/MIME.

"Off-the-Record Communication, or, Why Not To Use PGP"

In 2013, the Signal Protocol was introduced, which is based on OTR Messaging and the Silent Circle Instant Messaging Protocol (SCIMP). It brought about support for asynchronous communication ("offline messages") as its major new feature, as well as better resilience with distorted order of messages and simpler support for conversations with multiple participants.[11] OMEMO, introduced in an Android XMPP client called Conversations in 2015, integrates the Double Ratchet Algorithm used in Signal into the instant messaging protocol XMPP ("Jabber") and also enables encryption of file transfers. In the autumn of 2015 it was submitted to the XMPP Standards Foundation for standardisation.

the OTR protocol also reveals used MAC keys as part of the next message, after they have already been used to authenticate previously received messages, and will not be re-used

The answer, of course, is end-to-end encryption. The way this works is to remove any “man-in-the-middle” vulnerabilities by encrypting messages from endpoint to endpoint, with only the sender and recipient holding the decryption key. This level of messaging security was pushed into the mass-market by WhatsApp, and has now become a standard feature of every other decent platform.

The issue, though—and it’s a big one, is that the SMS infrastructure is inherently insecure, lending itself to so-called “man-in-the-middle attacks.” Messages run through network data centres, everything can be seen—security is basic at best, and you are vulnerable to local carrier interception when travelling.

When you make a call using Signal, it will generate a two-word secret code on both the profiles. You will speak the first word and the recipient will check it. Then he will speak the second word and you can check it on your end. If both the words match, the call has not been intercepted and connected to the correct profile

OK, so what about regular messages? Turns out they are not encrypted after all. Where Signal implements the security and privacy protocols right from the start, Telegram separates the two and offers an additional option. The problem is that not everyone is aware of the Secret Chat option and first-time users may send sensitive information in the regular chat window unknowingly.

And that’s where the real problem may lie—not with student semi-literacy but with that of their teachers.

This policy allows the test suite to stay green while letting individual teams decide when they would like to put in the effort to write more deterministic tests. They may choose to do so right away, or delay until they work on the feature again.

Contact Big and successful businesses are built on a talented workforce this is not just a saying but a solid fact. Hiring an employee is one of the most important tasks for a business and it becomes even more critical when it comes to hiring the right employee.  From Mark Zuckerberg to Richard Brandson every billionaire has similar thoughts when it comes to building the team and every one of them has one thing in common, they always seek quality, punctuality, and skills in an employee. Hiring an employee could be challenging also it may seem like a play of fate and this is a very common feeling but, having a guide or tips on how to hire the right employee could help you in tons. So, here is the list of 7 best tips on hiring the right employee. Make a Plan No matter what you do, planning is the very first step when it comes to achieving a goal. A written plan which contains essential components of the hiring like job descriptions, a skill required, Pay grade, timing, etc. is needed to hire a person. The plan that you make for hiring must contain various details regarding the requirement of the job. The details that would want to add in the plan is as follows-  Title  The post or title of the job that you’re looking for should also be given clearly. Someone who’s educated enough to be a CEO wouldn’t want to be a normal worker. Hence, the specifications of the position while looking for a new candidate should be clear.  Pay Grade  For hiring the new employees, you should first and foremost be true about the pay grade. Pay grades facilitate the employment process by providing a fixed framework of salary ranges, as opposed to a free negotiation. So, you should just align with the grading system to let your company work smoothly.  Reporting Person Reporting Person means the person who prepares reports on updates, progresses, accomplishments, etc. of the employees as well as the company in total. While hiring new employees, you should first submit their resumes to this person so that he can well-prepare a report and it gets easier for you to decide.  Timings You should also clearly mention the shift timings while looking out or hiring new employees. The working hours, the holidays, the relaxations should be clearly told to them and see if they can work with it or not.  Department Name You should also clearly defined the department for which you’re trying to hire the new employees. Human resource departments are often organized along with functions and may be hierarchical in nature. Common units in human resource departments include recruiting, training and development, compensation and benefits administration, health and safety, and employee and labor relations.  Job Summary, Purpose/Value A job summary is a brief, general statement regarding the important functions and responsibilities that comes with a job. Job summaries hold a huge role in enticing a qualified candidate to apply for the position and an employee’s performance of his or her responsibilities.  Challenges With a job, comes its challenges. So you should explain the kind of challenges that your newly appointed employee is going to face and mentally prepare. If your plan contains details like these then it becomes easy for you to post job requirements on job portals as well so, having a written plan on the hiring process is very important. Internal Job Rotation When we talk about hiring, we always think about finding a new person and use his services but, internal job rotation is something that no one thinks of and in certain conditions the best choice. If someone from your Department “A” has skills and talent to handle Department “B” then why not promote him/her to department “B”. There are many reasons why internal job rotation is better than hiring a new person, but to name a few- employee retention encourages development, eliminates boredom, and much more. Culture Fit If you want to hire the right employee, you need to make sure that they’ll fit in the company culture, your team, as well as the job. The best way to do that is by setting up a good interview panel. The interview panel is the one who asks questions and reviews the profile of the person to be hired. So asking a few cultural questions, liking, interest, hobbies, etc. helps the interview panel in deciding whether they’ll be a good match for our business or not. Go Beyond the Resumes Resumes are the best-foot-forward of a person. You need to go beyond that. A resume contains a person’s experiences, education, the last job is done, and much more but a person is much more than a piece of paper so, analyzing a person on the bases of personality, attitude, and style of speaking should also be analyzed thoroughly. Background reference Background reference is a very critical part of the hiring process. It is done to ensure that whoever you are hiring has a clean record. You can use the information provided by the employee like aadhaar card, social security number, etc. we can identify whether the person seeking a job is criminal or not. You can get police verification done along with enquiring with the previous employer. Competency Mapping Competency mapping is a process of identifying the competencies of an employee based on education and skills. When a person does a job basically he is using his skills and experiences in the job to get a favorable outcome. As a business manager or CEO, your job is to help your employee in bringing the best out of them and that can be easily done by working on their skills, education, and experience. Many business hire special corporate training specialists to train their employees and motivate them to achieve a better result in the job they do. When you are hiring a person it becomes hard for you to identify the competency of a person, at such situations you need to look at their previous work, question them on technical grounds, and watch their skill in action by conducting a test. Choose a Good Employment Agency Many small businesses often hire an employment agency to make their recruitment easy but they often miss out on key information on identifying a good employment agency. Basically, there are three types of recruitment agencies which are as follows- General Recruitment AgencyStaff Recruitment AgencyExecutive Recruitment AgencyAll in one agency Genera Recruiting Agency helps you find industry-based staff meaning this agency focuses on a niche industry like healthcare, engineering, etc. A staff recruitment agency is focused on temporary staffing solutions, this type of recruiting is done for seasonal businesses or project-based hiring. Executive Recruitment Agency is the agency that helps businesses in recruiting in executive positions like CEO, CFO, and Managers, etc. You can categorize the top-level position to C-level positions in this type of recruiting. As the name suggests, All in one recruitment agency is the agency that provides all these services like Yunic Solutions, We provide multiple recruitment services in every industry. After selecting the type of agency, you can decide your budget and go about researching the best recruitment agencies. Hiring the right employee in a nutshell Hiring the right employee is all about the experience. For some people, the first employee could be the right employee and for some people no employee is the right employee.But in general, Hiring is a core HR process that is essential for business and requires dedicated time and effort.
