mbq··on Why Asus trackpad driver sets the CPU speed at maximum during scroll
Not really a gamble -- you usually can find reliable info about Linux support on the internet, provided that the device is not too exotic.
mbq··on The Grid Uses Artificial Intelligence to Design Your Websites for You
AI is such an abused word that no one really knows what it is supposed to mean. Probably "automation" or "soft computing" are more accurate, but lack the cool factor.
mbq··on The Tup Build System
You can have a daemon (tup monitor), but it is not required; in the second case tup will compare last-mod times of files with those from the last run (stored in the .tup dir).
mbq··on Revolution R Open: The Enhanced Distribution of Open Source R
To be fair, free R+CRAN is also capable of all that stuff, not to mention that it can be easily compiled with ICC using MKL (provided that one has a license for them, but most academias have).
mbq··on Cryptic genetic variation in software: hunting a buffered 41-year-old bug
Thumbs up for not using rand, but the assuming that MT is a golden bullet is not exactly scientific; one should just test few RNGs, it may come in that the code exploits some ultra-hidden hole in MT or that some much faster RNG works equally well. Also reproducibility of a stochastic code means that the code results lead to the same conclusions regardless of the seed, not that you get bit to bit identical output for the same seed. In case one assumes (only) the latter, it may end up in seed cherry picking, not-optimizing code because it would "break reproducibility" or not investigating the natural deviation of the results.
mbq··on Revisiting Android disk encryption
On the other hand, the more system is loaded without user input the greater chance that it can be exploited; also filesystem-level encryption leaks some meta information.
mbq··on Revisiting Android disk encryption
That is a very good feature because forcing user to perform mentally demanding operation to dismiss the alarm decreases the risk of falling back to sleep (;
mbq··on Show HN: Mojulo – Pixelated Math Rendering Sandbox Toy
Fan is (y-50)/(x-50)+time/5, sin is to add texture. Multiplying x by cos and y by sine of the same frequency would simply rotate the fan centre around top right corner, slightly off periods (19 and 21) degenerate that circle into a more interesting Lissajous curve.

mbq··on Major Android Bug Is a Privacy Disaster (CVE-2014-6041)
Just switch to CyanogenMod or other custom compilation; there is a gain from Nexus brand in the ease of unlocking bootloader (;
mbq··on The Curious Case of iPhone 6+ 1080p Display
Reasonable UI systems and not-overdesigned programs respect your UI font size setting and scale the rest accordingly, while equal resolutions allow hinting to do its job and produce a sharp output in an intelligent way. The brute-force approach of densifying monitors is a dirty hack and luckily doesn't scale at all.
mbq··on String Deduplication – A new feature in Java 8 Update 20
Sure; in R strings are copied way more frequently than created, so it pays off.
mbq··on String Deduplication – A new feature in Java 8 Update 20
As a curiosity, global string cache is an old feature of R -- however strings are matched upon creation rather than detected by the GC.
mbq··on Entropy
Float operations are actually precise, the catch is that floats are not real real numbers.
mbq··on Why Some Schools Are Selling All Their iPads
I agree, but sadly this is something that on-line course organizers rarely consider.
mbq··on GNU datamash
Because with R you can and usually do multiple things with multiple data sources within one session, which effectively dissolves the start-up and load time. Even if reading one file and calculating mean or something with a single script is the only thing you do, you can use Rscript which runs R without loading heavy stuff like the methods package.
mbq··on Why Some Schools Are Selling All Their iPads
Blackboard is for the lecturer; it is easier to write formulas or draw diagrams interactively than with any digital tool. Plus the size; you can dump a lot of information without having to scroll anywhere.
mbq··on GNU datamash
That is not fair; you count R's start-up time and all the guesswork which read.table does and datamash doesn't have to do.
mbq··on The sad state of Linux Wi-Fi
Many chips/hardware pieces do already have a good Linux support, and the internet is full of info what will work perfect and what may cause problems.
mbq··on How to Read a Research Paper [pdf]
Does yours detect which part of the full-text is an author name, which is journal and which is publication date (mind the reference section present in practically every paper)? Does it index the notes you made on them?
mbq··on Microjs: JavaScript Micro-Frameworks and Micro-Libraries
The biggest problem with just writing some actual JS is a poor compatibility; when you try to generalise some one-liner working in a cutting edge browser you usually end up with a small library, plus the process is pretty painful. Thus those libraries' value mainly lies in research and testing required to make them work rather than in their core function.
mbq··on Machine Learning frameworks, libraries and software
Or simply a link to the ML CRAN Task View: http://cran.r-project.org/web/views/MachineLearning.html
mbq··on Finding the World's Economic Center of Gravity
Agree, COM in Mercator projection is even more wrong than the Economist method. If one wants to have it on sphere the only correct way to do this is by using the great circle distance. Obviously it still leaves a question what does this center of economic activity actually shows (;
mbq··on Microsoft Challenges Google’s Artificial Brain With ‘Project Adam’
They are not; this is machine learning not AGI, it is not even Turing complete.
mbq··on Color Emoji in Windows 8.1 – The Future of Color Fonts?
Actually it is a pretty dirty hack -- it seems ok because the flat design is currently popular. But quite likely gradients and shadows will come back in a few years and then few single-color layers won't be enough.
mbq··on Beautiful web type – typefaces from the Google web fonts directory
There is also infinality fontconfig mod, which brings even more options and some sane pre-sets (it can even mimic Windows).
mbq··on Android without the mothership
Than, what's the point of using a secure communication app if you must also install a spying rootkit to make it work? For me it makes the whole TS not viable.
mbq··on Android without the mothership
Isn't TextSecure already built into Cyanogen SMS app? And anyway dependent on the Google Play Services?
mbq··on Announcing Unicode 7.0
For instance a waste of time of font designers; you can make rational decision about including certain alphabets (by analysing the target group demands), but selecting a reasonable subset of bazyllion random, singular pictures to draw and test is a major headache. Obviously this way the users get inconsistent experience.
mbq··on ZFS Gotchas
You can make a btrfs NAS; then you can eject and add disks as you like, irregardless of their size.
