The 25mm 1.4 is much faster.

Let's compare how three 50mm f/1.4 lenses compare on three of the best digital cameras on Earth that you'd want to use in the field.

The image below was taken to test the Canon 5D Mark III in comparison to the Nikon D800 in order to demonstrate the differences between the two cameras and how they each capture small detail. I did this by shooting with the Nikon and the Canon using the same lens (Zeiss Distagon 21mm f/2.8) with an EOS adapter attached.

I have both the X100 and the GX1 and will say from the outset that they are very different beasts. The X100 is the most enjoyable shooting experience I've had since first shooting film. Despite the fact that all of the critical settings are right there at my finger tips and are more immediate in their availability and changability than any modern camera I've used, I find shooting with it to be a much more relaxed and deliberate experience. I've even regained some of my compositional skills as a result of the fixed focal length and general change in the way shooting feels with it. The GX1 roasts the X100 in terms of auto-focus speed, though I don't find it does any better acheiving focus in low light however (I don't run specific tests, just a perception based on usage ... which this week has ALL been low light). The difference here doesn't have that much of an effect for me though since neither of these cameras are what I'd reach for if fast auto-focus was a concern on a given shoot. In fact in general performance terms, image quality excepted, the GX1 is clearly the better device.

It is really hard to compare Napster and Spotify as they are entirely different beasts. Let me just say that I built the Napster server, so I'm biased.

Napster also had other advantages, including a wider catalogue, thanks to its disregard for licensing. Today Spotify wins on speed of access – streaming a song extremely rapidly. But of course it doesn't allow you to keep the song in a portable format; offline access is kept within the Spotify software's proprietary encrypted database.

We study the security and privacy of private browsing modes recently added to all major browsers. We first propose a clean definition of the goals of private browsing and survey its implementation in different browsers. We conduct a measurement study to determine how often it is used and on what categories of sites. Our results suggest that private browsing is used differently from how it is marketed. We then describe an automated technique for testing the security of private browsing modes and report on a few weaknesses found in the Firefox browser. Finally, we show that many popular browser extensions and plugins undermine the security of private browsing. We propose and experiment with a workable policy that lets users safely run extensions in private browsing mode.

This page pulls heavily from openSUSE's Software Management Command Line Comparison. It has been simplified and has added Arch to the comparison, as well as modified the order in which each distribution exists for the benefit of Arch users.

The spec consists largely of C code copy-pasted from the VP8 source code — up to and including TODOs, “optimizations”, and even C-specific hacks, such as workarounds for the undefined behavior of signed right shift on negative numbers. In many places it is simply outright opaque. Copy-pasted C code is not a spec. I may have complained about the H.264 spec being overly verbose, but at least it’s precise. The VP8 spec, by comparison, is imprecise, unclear, and overly short, leaving many portions of the format very vaguely explained. Some parts even explicitly refuse to fully explain a particular feature, pointing to highly-optimized, nigh-impossible-to-understand reference code for an explanation. There’s no way in hell anyone could write a decoder solely with this spec alone.

I was an Android user for quite some time and don't regret it. But honestly: Android devices aren't able to compete with the iPhone in the same market segment. iOS is mostly much more fun to use, the platform itself is more mature, there is a ton of really well implemented apps and the iPhone4 itself is just a great device. Of course, Android is more open than iOS and there are things an Android device can do which are just not possible or forbidden by Apple on iOS. But know what? - These corner cases don't bother me any more. I've been using my iPhone for a few months now. Even in the first days I was able to do more useful stuff with it than I ever did on Android in almost two years. At the moment I'm really pleased with the experience on iOS, but I'm also curious if this is the case in two years from now. Buy an Android phone if you want a smartphone that works and does its job. Buy an iPhone if you care about user experience and want a smartphone that works really well.

A few days back I wrote a somewhat controversial article called, “The Linux desktop experience is killing Linux on the desktop”. While many readers seem to have grasped the true purpose of the article, a lot of people claimed that it was nothing but FUD (a favorite term of many people in the Linux community, who would rather ignore existing problems than face/acknowledge them).

Tumblr now has more blogs than Wordpress, a pretty impressive milestone considering the startup was only founded in 2007. Tumblr is just much easier to sign up for and use than Wordpress. Wordpress blogs are geared toward longer form content, which is great but is attractive to fewer people. Tumblr, meanwhile, can be used by everyone to express themselves and share online. It's really doing what MySpace used to do--and we mean that in the best possible way.

If you've been pointed at this page, then the chances are you're a relatively new Linux user who's having some problems making the switch from Windows to Linux. This causes many problems for many people, hence this article was written. Many individual issues arise from this single problem, so the page is broken down into multiple problem areas.

OS X has been gimped for a long time, when it comes to pack­age man­age­ment – we’ve gone through fink, the awful ports sys­tem, and now home­brew. All this to get a slice of the Unix pie. But none of these offer a com­plete pack­age-man­age­ment sys­tem like that of­fered by Arch Linux. Home­brew, the only sane choice not only has a tiny pack­age repos­i­to­ry, but has been pret­ty un­re­li­able in my ex­pe­ri­ence, when it comes to in­stalling things with a lot of de­pen­den­cies, such as Haskell or couchdb.

My Compatibility Tables are by far the most popular resource on this site. Here you find the master table that contains links to the individual tables.

WhatTheFont is, hands down, the clear winner. When the IdentifyFont algorithm can actually recognize the image, we might be able to run another comparison. Until then, WhatTheFont has nothing to worry about.

Back in my original post about Internet video, I made some initial comments on the hope that VP8 would solve the problems of web video by providing a supposed patent-free video format with significantly better compression than the current options of Theora and Dirac. Fortunately, it seems I was able to acquire access to the VP8 spec, software, and source a good few days before the official release and so was able to perform a detailed technical analysis in time for the official release.

Mac OS X Portal Performance: ~40% slower, worse image quality than Windows. I think Mac users will have to go through the earlier attempts that us PC users had to go through when Steam first launched. It does get better with time.

This article discusses the "-execdir" option to "find" and the use of "\;" or "+" to terminate the arguments supplied to "-exec" or "-execdir". Please note that these things are likely to change. When this was written, Mac OSX "find" in Leopard worked differently than "find" in a current Linux. Both may work differently than described if you are reading this at a much later date than it was written or are using a different version of Linux or MacOSX.

Once we took the Seagate Barracuda LP 2TB out of the running, it was a very close call between the Samsung EcoGreen F3 2TB and WD Caviar Green 2TB, but we ultimately chose the Samsung EcoGreen F3 2TB because of its speedier overall performance.

I won't do it. The problem with web programming is that it is all experimental. You simply cannot do anything correctly. It's like writing cross-platform code that has to compile with a C++ compiler on one system and a Fortran compiler from a different vendor on another. While an interesting problem, it's not programming. All the backend stuff, anything that doesn't need to render a specific way, the system programmer is happy to do. It's easier and enjoyable, there are all kinds of places for optimizations based on algorithm choice... it's great. However, as soon as any HTML needs to be output, the systems programmer reads the spec, implements based on the spec, becomes horrified at just how BAD everything is and at the fact that you simply can't make it work on every platform. At this point, programming is no longer happening, it's research and experimentation... it's QA... it's nasty.

Imagine. You need to find the file with that unmerged effects among the heap of 2 mb files which were called hastily 'Untitled1.psd, 'Untitled2.psd', 'Untitled2_a.psd'. And now you have to open every single file, wait for it to load, scroll through it, and then find the effects you was looking for. Sounds familiar? ComparePSD compares two Adobe Photoshop PSD files for you and highlights the differences. Layer by layer. Effect by effect. Simple. And did we mention that ComparePSD is absolutely free?

Before we go, we can't ignore the fact that our overall leader in both power efficiency and performance per system cost was the Core i5-750. If you're purely rational about these things—and you can afford to spend nearly $200 on a CPU—the i5-750 is obviously the best choice among the processors we tested.

If you try to look like a messenger and go to Handlebar with a brand new timbuk2 bag, a stock langster, and "messenger knickers"(tm), you will look like a complete tool and people will laugh at you. Also, unless you have some decent traffic skills (like 500+ hours on a fixed) riding in congested traffic you will ride slowly and look like a deer in the headlights.

Finally, we should accept that most reasonably designed typefaces in mainstream use will be equally legible, and that it makes much more sense to argue in favour of serif or sans serif typefaces on aesthetic grounds than on the question of legibility.

Google recently launched it’s own Public DNS offering, allowing Internet users to make use of their DNS servers for resolving address queries on the Internet. I have been a fan and user of OpenDNS for quite some time now, which offers the same service with many more options (as compared to Google’s new service). Immediately, I was curious as to how Google’s service compares with OpenDNS.

Over the years I've heard fans of Capture One tout the image conversion quality possible in that app. Unfortunately, I've always found it difficult to get any actual, concrete demonstrations of what they're talking about. Lately a number of people (all using fake email addresses, oddly enough) have commented here about how C1 produces "better quality," yet none of them have been able to back up their claims. So, I ask--not to pick fights, not to start any holy wars, but out of constructive curiosity: Are you getting better results with a raw image processor besides Camera Raw or Lightroom*, and if so, are you willing to share your images (raw & processed) so that we can see exactly what you like/dislike? This sort of concrete data is precisely what we need in order to keep making progress. If you're interested in participating, please add a comment or drop me a line.

I learned ACR when it appeared as a plugin to Photoshop. Of course, a friend who keeps up with technical issues says that ACR is not a good raw converter for the camera I've been thinking about buying next. He's recommending a third-party converter that has a "steep learning curve." Great. And on it goes. I'm guessing none of this is unfamiliar to you. A change in one link of the chain changes other links; and something or other is always changing. And if it hasn't changed yet, you know it will. Maybe not soon, but probably sooner rather than later. You have to keep up. To put it overly simplistically, it's the difference between running, and running on a treadmill. This isn't necessarily worse, just different. But I would say that, for me, this is the biggest difference between the practice of photography now and what photography was like when I built my first darkroom in a bathroom under the basement stairs.

Maemo isn't perfect, but still much ahead of Android. Development for Maemo has the potential to benefit existing Linux distributions, and many desktop apps will surely be interested in adding a mobile-optimized GUI as a compile time option. CLI applications will work without trouble, and experienced Linux users can easily connect to their desktop computers using SSH and X11. The Nokia N900 officially supports root access. Android is an island of its own, and useful code sharing is largely limited to the kernel. Developers can't even always use the language of their choice. Android hardware manufacturers can't be trusted to allow users the freedoms the software would grant, let alone fight network operators.

This small article is to show that the matter is much more complicated. At the current stage the situation with RAW format is not just bad but really dreadful and continues to spiral downwards rapidly. This affects mostly professionals while less demanding amateurs simply enjoy the progress of digital.

I've taken 20 logos that were originally designed in Helvetica, and I've redone them in Arial. Some people would call that blasphemy. I call it a challenge: can you tell which is the original and which is the remake?

According to tests run by Computerworld, Internet Explorer 8 (IE8) with the plug-in was 9.6 times faster than IE8 on its own. Computerworld ran the SunSpider JavaScript benchmark suite three times each for IE8 with Chrome Frame, and IE8 without the plug-in, then averaged the scores.

Here’s a nifty little graphic showing the difference between Arial and Helvetica.

Den nya mobilen mäter 106x55x14 mm och väger 113 gram, och är därmed några millimeter nättare än Hero och 20 gram lättare. Skärmen har hälften så hög upplösning -- 240x320 pixlar mot Heros 320x480 -- och är med sina 2,8 tum också något mindre. Kameran på 3,2 megapixel är också något enklare än Heros 5-megapixelkamera med autofokus. I övrigt är specifikationerna mycket lika, även när det gäller mobilens processor, vilket borde göra Tattoo snabb.

As a former iPhone user who switched to Android, I can say: iPhone 3.0 hasn't made me regret my decision. Yet. Right now, Android's killer Gmail client, proper MMS support (available now), background processes (even though they kill the battery), window shade, and general Google product integration makes me a happy camper. In fact, on the chart above, the top five items are the features most important to me, and Android—right now, not this summer—hits on almost all of them.

Problem. You are interested in how the Google Chrome 3.0 Dev, Firefox 3.5 RC, Safari 4.0 for Windows, and Opera 10b web browsers manage memory on the Windows Vista operating system over moderate usage, such as with 150 top web sites. These numbers can be measured but there are complexities involved in measuring memory. Solution. Here we look at a program that simulates a user visiting the top 150 web sites from Alexa from the command line, with visits occurring at short but varying intervals in many tabs.

GIMP is not "open-source Photoshop". It does not support image depths over 8 bits, RAW files, CYMK, or decent color calibration. It does not have Adjustment Layers, layer groups, quick Action recording (hey, you have to learn a programming language to do that! yay!), or a huge library of plugins (some have been written for the thing, I think every single one of the half-dozen are included with the software). SVG format support is hardly there, either, and the typography support is rudimentary, at best. The interface is bizarre, with the standard buttons and tool palette eating up half your screen, and so much padding around each UI element consuming more space than the image you're trying to work on, but can't, because it's buried under so many UI elements, and each toolbar and the program itself all getting a space in your "running applications" area.
