Systems that respond to user actions quickly (within 100ms) feel more fluid and natural to users than those that take longer. Improvements in Internet connectivity and the rise of warehouse-scale computing systems2 have enabled Web services that provide fluid responsiveness while consulting multi-terabyte datasets spanning thousands of servers; for example, the Google search system updates query results interactively as the user types, predicting the most likely query based on the prefix typed so far, performing the search and showing the results within a few tens of milliseconds. Emerging augmented-reality devices (such as the Google Glass prototype7) will need associated Web services with even greater responsiveness in order to guarantee seamless interactivity. How Google builds for high utilization and responsiveness.

One of the dreams for security experts is the creation of a quantum internet that allows perfectly secure communication based on the powerful laws of quantum mechanics. The basic idea here is that the act of measuring a quantum object, such as a photon, always changes it. So any attempt to eavesdrop on a quantum message cannot fail to leave telltale signs of snooping that the receiver can detect. That allows anybody to send a “one-time pad” over a quantum network which can then be used for secure communication using conventional classical communication. And now that they've told you, they'll have to kill you.

Gender equality is still a major issue in the technology industry, but 50 years ago one British company was blazing trails.... The company, originally called Freelance Programmers, was founded in the early 1960s by Stephanie Shirley, a German who had been evacuated to Britain — along with many fellow Jewish children — as part of the kindertransport shortly before the Second World War. Solving the problems of gender and parenting one byte at a time.

In most orthodox Jewish communities, not only that the men are not dominant in this but actually there are far more women software developers than men!
Never underestimate the difference you can make in the lives of others.

Worried about your longevity as a worker in the fast-moving tech industry? What you need is some inspiration from John Sloan. Who's John Sloan? He's the man pictured in a photo I used in a recent post on 10 Technology Skills That Will No Longer Help You Get A Job. (See that photo below - or on the iPad in the photo above.) While Sloan may look like a symbol of outdated technology in the older photo, he's actually the polar opposite. An interesting follow-up to 10 Technology Skills That Will No Longer Help You Get A Job.

Cool article. I especially enjoyed the fact that he graduated from Wright State University in 1976, as I graduated from there in 1984.
I can attest to what he says is true: professional development and skills maintenance is up to you, and largely you alone. I've done it by encouraging my employer to use technologies that were interesting and appropriate to the task at hand. I've also expanded my horizons through outside consulting. You can't really learn a new technology without have a genuine problem to solve.

I may maintain that the fact that Microsoft has sold 100 million Windows 8 licenses in six months doesn’t mean much. But that doesn’t mean that Windows sales figures aren’t interesting. In fact, Microsoft’s news moved me to rummage around in Google Books, Microsoft’s press site and elsewhere for past sales data for various major editions of Windows dating back to version 1.0, which debuted in November 1985. That's a lot of Windows to open.

It seems Exchange Online is not working. I just got a rejection notice when I tried to send myself an email, then checked the service health and noticed this.

Update: Microsoft O365 Service Operations has implemented a potential fix for the issue with the Global Locator Service for Exchange Online. Some users may experience issues signing in. This only affects users on Exchange 15. We will provide further information as it becomes available.
I'm getting emails again, so I guess their potential fix worked.

Do you need to monitor your Linux server’s performance? Most Linux distributions come equipped with many built-in monitoring tools. These tools allow you to retrieve information about system activities, and can be used to find possible causes for your server’s performance issues. The commands discussed in this article are some of the most basic commands when it comes to system analysis and debugging server issues, such as discovering disk, CPU, memory and network bottlenecks. sudo what's going on with my servers?

You spent an entire weekend building a library, jQuery plugin, build tool, or other great piece of code you wanted to share far and wide, but after some tweets and a failed attempt to make the front page of Hacker News, your creation languished, unloved, in a GitHub repo. A common situation for many developers nowadays, but one you can avoid. Pro tip: write about it here on CodeProject!

All programs need some form of logging built in to them, so we can observe what it is doing. This is especially important when things go wrong. One of the differences between a great programmer and a bad programmer is that a great programmer adds logging and tools that make it easy to debug the program when things fail. When the program works as expected, there is often no difference in the quality of the logging. However, as soon as the program fails, or you get the wrong result, you can almost immediately tell the good programmers from the bad. How do you write code to simplify debugging?

JavaScript is a bubble. Just like the housing bubble. Just like the .COM bubble. And just like any bubble, the JavaScript bubble is bound to pop. Sure, JavaScript is everywhere. It appears to be growing at a rapid pace. But I’m willing to bet that we are getting close to a complete reversal that will throw JavaScript down from its throne, shattering its JQuery scepter with it. JavaScript is bad, so let's rewrite everything in something else. Then we'll go after PHP.

Quote: Yet, at the same time so many developers get up in the morning, fire up their IDE—or excuse me, lightweight text editor which has 50 plugins installed to give the capabilities of an IDE, but is not an IDE—and write JavaScript code. Why do they do it, unless they think JavaScript really is awesome?
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

When you think of mobile games, you probably think of titles like Angry Birds, Temple Run or Fruit Ninja — not the sort of micromanaging strategy games for which Sid Meier is best known. And yet the creator of the hit Civilization franchise and his company, Firaxis Games (owned by Take-Two Interactive), are moving more troops into mobile after testing the waters with ported games like Pirates! and Civilization Revolution. Rather than just producing, Meier himself was one of three programmers on a new mobile-first Firaxis game, Ace Patrol. Mobile is best suited for a game that’s played at the player’s pace.

We suggest a simple method for improving the security of hashed passwords: the maintenance of additional honeywords (false passwords) associated with each user's account. An adversary who steals a file of hashed passwords and inverts the hash function cannot tell if he has found the password or a honeyword. The attempted use of a honeyword for login sets off an alarm. An auxiliary server (the honeychecker) can distinguish the user password from honeywords for the login routine, and will set off an alarm if a honeyword is submitted. Passwords are a notoriously weak authentication method. Fake passwords are better?

Once upon a time, teachers lacked the tools to excite and engage pupils in engineering. And the technological know-how required to put together a juddering robot limited the audience to high-school and university students. That all changed in 1998 when Lego launched its first wave of programmable bots. By the second wave, in 2006, the programming language had become visual and kids could make bots do pretty much anything simply by stringing directives together on a computer. “Today a second grader can make her own wall-avoiding triceratops in 20 minutes,” says Chris Rogers, a professor of mechanical engineering at Tufts University. Go find a Mindstorms education catalog and prepare to have your mind blown.

Bill Gates took a shot at the iPad while explaining Microsoft's rationale for the Surface this morning on CNBC. He was asked about the declining PC market. He said that tablets are growing in popularity, and it's "going to be harder and harder to distinguish products" that are PCs versus tablets.... He then said of people using iPad-like devices, "A lot of those users are frustrated, they can't type, they can't create documents, they don't have Office there." I'm still waiting for that TPS reports app.

Just stumbled across this site while answering a question in Q&A:
CWE™ International in scope and free for public use, CWE provides a unified, measurable set of software weaknesses that is enabling more effective discussion, description, selection, and use of software security tools and services that can find these weaknesses in source code and operational systems as well as better understanding and management of software weaknesses related to architecture and design.
Interesting site at first view, I think I'll have to take a closer look at this: Common Weakness Enumeration[^]
