There are many different data structures used in databases to create indexes used to quickly evaluate queries. Each one has different strengths and weaknesses based on the tradeoffs they make on memory, cpu and storage (if persisted). One of these types of indexes is called a bitmap index. For the purpose of this post I’m going to be using relational database terminology but the same techniques can apply to different database types like column oriented databases or many others non-relational databases.

Though technically links aren't a requirement to make the internet function (you can get by on just urls), they are the primary reason why the web took off so gloriously. Linking is an essential part of every web page out there, without links we would be copying urls the entire time (or we wouldn't because who likes to work like that). But the implementation of links (the html a-element) has been broken since the very beginning of the web and with the addition of block-level links things only got worse.

When you buy a Raspberry Pi, the $35 computer doesn't come with an operating system. Loading your operating system of choice onto an SD card and then booting the Pi turns out to be pretty easy. But where do Pi-compatible operating systems come from? With the Raspberry Pi having just turned one year old, we decided to find out how Raspbian—the officially recommended Pi operating system—came into being. The project required 60-hour work weeks, a home-built cluster of ARM computers, and the rebuilding of 19,000 Linux software packages. And it was all accomplished by two volunteers.

“Should I join Microsoft or a startup?” As the co-founder of a profitable startup and a former Microsoftie, I hear this question a lot, especially from college students ready to start their careers. In tech cities like Seattle and San Francisco, we’re quick to jump on the pro-startup bandwagon. Robert Scoble advises: “Join a startup. You will learn more there and have a bigger impact. Later, when you have a family and a mortgage, you can take the safe route.” But this advice ignores the advantages—like knowledge, confidence, and money—to working for a Microsoft, Google, or Amazon first.

Roku 3 is the latest in a long line of set-top boxes that date to the days when TVs had but 13 channels you could see only after fiddling with a pair of rabbit ears wrapped in foil. (Ask your grandparents. They’ll tell you all about those dark days.) Now we have set-top boxes -- most of which actually sit under your ultra-thin HDTV -- that let you watch DVDs, stream video and play games, often from a single gadget. Ain’t progress wonderful?

Google's Chrome OS, thanks to the growing popularity of Chromebooks, is being used by more and more people. Many people know that Chrome OS has a Linux foundation. But how Chrome OS developed from Linux, and exactly what is in Chrome OS today, has been something of a mystery -- until now.

VARIETY is the spice of life, though not if you are the maker of an ageing internet browser maker losing ground to your younger, nimbler competitors. Microsoft, maker of the Windows 8 operating system and the Internet Explorer web browser, has been fined €561m ($732m) by the European Union’s antitrust regulators for breaking a promise to offer its customers a choice of the browser they would like to use to surf the internet on their personal computers.

Microsoft needs to improve customer engagement, dramatically. And the first thing that will take is to recognize that the consumer teams’ attitude towards communicating futures is just plain wrong. That doesn’t mean abandonment of controlled information release, it means applying it more intelligently. It means disclosing platform direction early. It means bringing developers on board early. It means giving general technology direction to the public early (ala what BillG used to do) without talking specific releases or products. It does not mean releasing every detail of a product in advance.

When I recommend learning Haskell to the uninitiated, I often get asked: “Why Haskell?” “Is it a practical language?” and ”Is it something I can actually use?” My answer is definitely yes. Haskell isn’t my primary language at work (I mostly write C code for embedded systems), I’ve still found it incredibly useful. And even if I never used Haskell at work, I would still consider learning it as time well spent. So, why Haskell?

Ars Technica[^]:

Android and iOS have existed in tension for a few years now, and each is continually borrowing ideas, designs, and features from the other. Nothing wrong with a little friendly theft when trying to stay competitive. The operating systems are far from exact mirrors of each other, and they have even grown more distinct with new generations. But there are a few features we’d still love to see cross sides, in the interest of keeping the operating systems functional and easy for customers to use.

On the surface, a microprocessor's registers seem like simple storage, but not in the 8085 microprocessor. Reverse-engineering the 8085 reveals many interesting tricks that make the registers fast and compact.... Each bit is implemented with a surprisingly compact circuit. The instruction set is designed to make register accesses efficient. An indirection trick allows quick register exchanges. Many register operations use the unexpected but efficient data path of going through the ALU.

Businesses are mostly just now upgrading to Windows 7, and won’t go to Windows 8 for 2-4 more years. So in a sense you can argue that Microsoft has a lot of time to fix the side-loading story, because almost no one is going to care about this for a long time anyway. On the other hand, the developer community tends to move a bit faster. We’re a fickle bunch. If we don’t perceive WinRT as a viable future platform for business apps then we’ll start retooling our skills to something else in order to preserve our careers. That won’t take 4 years. I suspect Microsoft has less than 2 years to get developer buy-in to WinRT or the siren call of h5js will become too much to bear.

In 1995, sales of pagers were booming among Japan’s teenagers, and NTT Docomo’s decision to add the heart symbol to its Pocket Bell devices let high school kids across the country inject a new level of sentiment (and cuteness) into the millions of messages they were keying into telephones every day. Docomo was thriving, with a bona fide must-have gadget on its hands and market share in the neighborhood of 40 percent. But when new versions of the Pocket Bell abandoned the heart symbol in favor of more business-friendly features like kanji and Latin alphabet support, the teenagers that made up Docomo’s core customer base had no problem leaving for upstart competitor Tokyo Telemessage. By the time Docomo realized it had misjudged the demand for business-focused pagers, it was badly in need of a new killer app. What it came up with was emoji.
