LevelDB

oren.github.com/posts/leveldb.md at master · oren/oren.github.com · GitHub: "LevelDB is a very fast and lightweight embedded database. It was created by two Google engineers and is inpired by BigTable, Google's proprietary file system. You are probably using it without knowing it since it's part of the Chrome browser (exposed as IndexedDB).

Other databases in the embedded category are BerkelyDB and SQLite (it's important to point out the LevelDB is faster). By embedded it means you don't run it in a separate process as you would normally do with many of the popular databases such as MySQL, MongoDB or Redis. LevelDB is contained within your application process and can't be accessed from other process. It is literally just a file based store of key value pairs that does some fancy caching and compression.

If we compare it to Redis, it's even lighter, have more reliable writes and unlike Redis, you don't store your entire data in memory but in the file system. Another difference is Redis have more data structures (sets, lists etc) that LevelDB is lacking. The similarity is that both store key-value pairs and both can save json."

Quick Tip: Add Easing to Your Animations » Learning jQuery - Tips, Techniques, Tutorials

Quick Tip: Add Easing to Your Animations » Learning jQuery - Tips, Techniques, Tutorials: "Easing can really bring life to an effect. Easing controls how an animation progresses over time by manipulating its acceleration. jQuery has two built-in easing methods: linear and swing. While they get the job done, they are pretty boring when compared to what's made available through the jQuery easing plugin."

CSS Masking - HTML5 Rocks

CSS Masking - HTML5 Rocks: "Two commonly used operations in computer graphics are clipping and masking. Both operations hide visual portions of an element. If you have worked with SVG or HTML Canvas before, these operations are probably not new for you. Clipping defines the region of an element that is visible. Everything around this region does not get rendered - it gets "clipped". On masking, a mask image is composited with the element, affecting the alpha channel of this element. Portions of a masked element get fully or partially transparent. The new CSS Masking specification aims to bring these two operations to the HTML world."

IE8 Developer Tools won’t open | David Tong

IE8 Developer Tools won’t open | David Tong: "This may sound stupid, but I ran into this issue that upon pressing F12 or choosing Tools > Developer Tools, the IE Developer Tools window does not show up. It is, however, showing up in the task bar.

The issue is that when you have Developer Tools detached from the browser window, and you don’t close it before exiting the browser, the next time you open IE8 and try to run Developer Tools, the Developer Tools window will be an ‘invisible state’ (simply put…).

The solution is to right-click on the tab/ icon in your Windows task bar and choose Maximize. If there is no such option in Windows 7, hover on the tab/ icon in the task bar for a moment until an overlay pops up that shows all the IE8 instances and the Developer Tools representation view, right-click on the Developer Tools’ representation view and choose Maximize. Alternatively, you may do Alt+Spacebar, then hit ‘m’ and start using your arrow keys to move the window around. You will then be glad to see your long-lost friend!

It sounds stupid, but this is still a kind of IE bug."

Easing Functions Cheat Sheet

Easing Functions Cheat Sheet:

Easing function specifies the speed of animation progresses to make it more realistic.

The real object doesn’t begin its movement instantly and at a constant rate. When we open the drawer, we first give it acceleration, and then we slow it down. When something falls, it first goes down faster and faster, and then bounces back after it hits the floor.

How to play Zopfli with Nginx - Google Drive

How to play Zopfli with Nginx - Google Drive:

The Zopfli Compression Algorithm is a new, open sourced general purpose data compression library that got its name from a Swiss bread recipe. It is an implementation of the Deflate compression algorithm that creates a smaller output size compared to previous techniques. The smaller compressed size allows for better space utilization, faster data transmission, and lower web page load latencies. Furthermore, the smaller compressed size has additional benefits in mobile use, such as lower data transfer fees and reduced battery use. The higher data density is achieved by using more exhaustive compression techniques, which make the compression a lot slower, but do not affect the decompression speed. The exhaustive method is based on iterating entropy modeling and a shortest path search algorithm to find a low bit cost path through the graph of all possible deflate representations.

The output generated by Zopfli is typically 3–8% smaller compared to zlib at maximum compression, and we believe that Zopfli represents the state of the art in Deflate-compatible compression. Zopfli is written in C for portability. It is a compression-only library; existing software can decompress the data. Zopfli is bit-stream compatible with compression used in gzip, Zip, PNG, HTTP requests, and others.

Due to the amount of CPU time required, 2–3 orders of magnitude more than zlib at maximum quality, Zopfli is best suited for applications where data is compressed once and sent over a network many times — for example, static content for the web. By open sourcing Zopfli, thus allowing webmasters to better optimize the size of frequently accessed static content, we hope to make the Internet a bit faster for all of us.

The ultimate “target retina screens” media query

mir.aculo.us JavaScript with Thomas Fuchs » Blog Archive » The ultimate “target retina screens” media query:

There now is an abundance of devices with some sort of high-density display, from MacBook Pros to iPads, from Windows Surface tablets to all kinds of mobile phones.

All of these devices have one thing in common: In web browsers (that support the high-density screen correctly) one CSS pixel is not equal to a physical screen pixel.

In terms of CSS, to specifically target this group of devices, unfortunately there’s no easy way to say “apply this set of rules to all devices where physical pixels are not equal to CSS pixels”. Instead you have to fight through a whole forest of media query rules.

@media (min--moz-device-pixel-ratio: 1.5),

(-o-min-device-pixel-ratio: 3/2),

(-webkit-min-device-pixel-ratio: 1.5),

(min-device-pixel-ratio: 1.5),

(min-resolution: 144dpi),

(min-resolution: 1.5dppx) {

/* Retina rules! */

}
