I’ve regularly received questions from developer friends who are a bit baffled with images and the somewhat confusing formats. I’m also heard from some developers that they hate receiving a PSD with no instructions and having to wade through the overwhelming options of Photoshop. This short guide is aimed at explaining the basics of image formats and giving you some simple rules that you can apply everyday when you are actually trying to get [work] done with Photoshop. The ABCs of JPGs, PNGs, and more.

Quote: Progressive means that the JPG is downloaded in chunks and after only a little of the image has downloaded it will be displayed full size, but blurry. As more of the file is download the image will rerender with a higher degree of clarity. Without progressive JPGs need to completely download before displaying, leaving a glaring open space on your page. Having something there, even if it is a chunky and blurry version, is a better experience. I always use progressive and it generally doesn’t impact files ize much, but keep an eye on the file size in case.
Bleck! Maybe for navigation images a chunky version might be beneficial, but even on a slow connection those still load rapidly. 99% of the time when I notice a progressive JPG my only reaction is to snarl about the serious of bletcherous low quality versions wasting some of the servers pathetically low bandwidth and making me wait even longer for the only version I want to see to actually load.
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?

LG announced yesterday that it would be acquiring webOS from HP to use in LG smart televisions. The company has inherited all of the rights to the source code for webOS, including documentation and engineers, as well as all of its related websites. But what about projects like Open webOS and webOS Ports? Open source will be alive and well at LG. Famous last words?

Internet Explorer 10 is available worldwide in 95 languages for download today. We will begin auto updating Windows 7 customers to IE10 in the weeks ahead, starting today with customers running the IE10 Release Preview. With this final release, IE10 brings the same leading standards support, with improved performance, security, privacy, reliability that consumers enjoy on Windows 8, to Windows 7 customers. Windows 7, Windows 8, IE9, IE10... Does this one go to 11?

Wow. This is certainly a departure. If you're going to charge an obscene premium for a laptop with an incredibly limited OS, you'd better produce something that is incredibly well-made. In that regard, the Chromebook Pixel is a complete success. If you'll forgive us just one cliche, Google has gone from zero to hero with the Pixel. It's truly something to behold. This amazing laptop runs... a browser?

I was aware of the Surface Pro but I wasn’t especially interested in it until I heard it came with a stylus and supported pressure sensitivity. I love gadgets and drawing so it only makes sense that I’ve always been curious about gadgets you can draw on. Since the old Windows tablet computers I’ve been looking for a good way to draw digitally on the go. I gave the iPad a shot but I don’t like drawing with the “eraser tip” capacitive touch styluses. When I read that the Surface Pro uses Wacom tech I was interested... Comics, sans laptop.

I think he pretty much said what I would about the Surface Pro. I love mine, it's much better than a tablet, but can sub for a laptop easily and you can carry it easily. I put a microSD card in mine to get an additional 32 GiB of storage and also carry a 1 TiB USB drive when I travel for business, so the 128 GiB limit isn't really an issue for my uses.

Server 2012 is the Microsoft operating system that, in my opinion, makes cloud computing a reality. As far as I am concerned it is as big a leap over Server 2008 R2 as that OS was over Server 2003. With it you can build anything from a small cluster to a service as big as Microsoft's own Azure platform. Which is why I am completely baffled as to how it is possible that Azure was knocked offline by last week's SSL c**k-up. Leaving the reputation of a flagship cloud service hanging on a single forgotten semicolon.

Parents whose kids blew their money buying virtual goods in "free" apps from Apple's iPad store will be getting refunds in the near future. That is, if a judge approves a settlement recently filed in a class-action lawsuit. Have you also been victimized by those easy in-app purchases through your kids?

The outage affected as many as 52 different Microsoft services, including Xbox Live, for up to 24 hours.
This is the second time they've had an outage due to an SSL certificate issue. They really ought to get somebody who knows what they're doing.

Did you know you could traceroute over the TCP protocol? The regular traceroute usually uses either ICMP or UDP protocols. Unfortunately firewalls and routers often block the ICMP protocol completely or disallow the ICMP echo requests (ping requests), and/or block various UDP ports. However you'd rarely have firewalls and routers drop TCP protocol on port 80 because it's the web's port. Connect the hosts.

If you search the Mozilla Central code base for the texts "Perl" and "Python" (don’t ignore case) then the comments mention what methods have been borrowed from those languages. ...plus influences from JavaScript to CoffeeScript and back to EcmaScript 6!

Build a JPEG decoder? Whatever for, when we have so many of them already? JPEG is something we all take for granted: most of the Web comprises pictures transmitted as JPEG files, and video files based on JPEG technology. As it turns out, the concepts that lie behind these images span nearly two hundred years of mathematics and computing theory, and going from the raw file to an image takes a bunch of interesting work. A three-part (and growing) series of tutorials on building a DIY decoder.

Broken link.
I'd really like to read this too. Years ago, I was thinking of implementing a JPEG decoder/encoder, but backed off when I found out that the specification document cost several hundred dollars.

These days I only use JPegs in printing, publishing, photograpy only at max quality no loss or min loss. Lossy compression was fun a decade ago. But nowadays it exists because of the widespread base. Relatively speaking LibTif by Sam Leffler is a piece of Engineering Marvel.

Despite the advantages offered by FPGAs and their rapid growth, use of FPGA technology is restricted to a narrow segment of hardware programmers. The larger community of software programmers has stayed away from this technology, largely because of the challenges experienced by beginners trying to learn and use FPGAs. Comparing Verilog, OpenCL, Liquid Metal and other frameworks you've probably never heard of.

In many organizations, it's expected that any persistent data will be stored in relational databases that are managed by a central database management group. There are various reasons for such central control, usually centered around using IntegrationDatabases. Central data groups worry about keeping out malformed data, queries that can slow down important shared resources, and consistent data models across the enterprise. Worthy these aims may be, but one consequence of them is considerable ceremony about storing data. Using a NoSQL database to avoid the DBAs when a relational database would be a better choice.
