samuel··on The Narcissism of Small Code Differences (2008)
So agnostic code has a bug since doesn't raise an Exception in the else clause?

Anyway the others changed the algorithm, interpreting what they believed it should do. That's something unavoidable sometimes due to convoluted code and lack of documentation, but not in this situation.

samuel··on Formula 1′s Leading Team Has a Big Secret
That implies to make cars that are too dependent of aerodynamic performance, which makes them incapable of overtaking.
samuel··on Formula 1′s Leading Team Has a Big Secret
Vettel was cruising most of the race. That's what he has been doing during all the seasons. He opens a gap in few laps and takes care of tyres and engine for the rest of the race. If needed(as after a Safety Car), he does it again.

He's a great driver, no doubt about it, but he isn't head and shoulders over ALO, HAM or RAI.

samuel··on Archaeology: The milk revolution
Project LeChe, great name!! Leche is the spanish word for milk.
samuel··on Source Code for the book “Machine Learning Systems with Python”
Why on Amazon? O'Reilly sells it drm-free. I bought it yesterday using a coupon(which are pretty easy to find).
samuel··on Spaniards are less productive, constantly tired: Spain is in the wrong time zone
So the roots of the current real state bust may be found in the invincible Armada in the 1600s(BTW nobody in Spain put it that name, and that episode wasn't the end of the war, which didn't end so badly to Spain). Yeah, great analysis, thank you. Trafalgar didn't appeal to you?

The reasons of Spanish underdevelopment during the past centuries are several and have been studied thoroughly and have nothing to do with "being lazy" as you seem to suggest.

I detest how every news that involves Spain is linked to the current crisis. Just 5 years ago Spain was a model of economic growth and progress and we lived at the same Time Zone.

samuel··on Save 50% on All O'Reilly Ebooks and Videos
BTW, Oreilly books can be bought on Google play(epub only) by less than 4 eur. Not the newest ones, though.

samuel··on One Laptop Per Child launches XO tablet via Walmart
What happened to the b&w-sunreadable screen?
samuel··on Mammals can 'choose' sex of offspring, study finds
Men with higher testosterone levels are more likely to produce male offspring. So I agree with you. It seems easier to put the gender bias mechanism in the males.
samuel··on Opera 14 for Android is out, based on Chromium
Feels slower on my Galaxy S Plus. I'll try it a bit more, but the first impession ain't good...
samuel··on Issue 8788 - Every day around 9 AM Brussels time, huge drop in GAE performance
The potential bad press that Google would get if Khan Academy had daily issues due bad GAE performance I'm sure that would cost them much more than the 500$/month that you're paying. Being big and nice(or cool) I think it gives and edge here.
samuel··on Devops/Sysadmin Cheatsheet
I really wasn't clear about what I wanted to say, sorry. birthtime is different from ctime on those systems. Ctime is last change on the inode as parent said.

I just wanted to note that some Unix systems really store the creation time. See http://www.daemon-systems.org/man/fstat.2.html for an example.

samuel··on Devops/Sysadmin Cheatsheet
Regarding ctime, some Unix versions(or I should say filesystems) really store the creation time(birthtime) of the inode. FreeBSD's find has the -Bmin switch for searching for true creation time.
samuel··on Students Rush to Web Classes, but Profits May Be Much Later
I may be dumb, but why not try to charge for the courses upfront? You offer a preview for free and charge a small fee for the full course(15$ for example). Once the videos are recorded, the costs for coursera and the professor should be very low, and the number attendees of every class are in the thousands. Couldn't be profitable that way?

If 15$ is still too much for some(someone who already has access to a decent computer and broadband internet), they could create a system of grants. Most people wouldn't lie just for saving such a small quantity.

samuel··on Will Scientists Ever Move to Python 3?
I couldn't agree more. If you're going to break compatibility, do it for a good reason. Type annotations, that would appeal to scientists(BTW, a lot of them are using Cython)...
samuel··on The second coming of Java
This ignores the fact that most web applications are developer-bound well before they became IO bound, and much much before they became CPU bound.

Anyway, Java EE is alive and strong in the enterprise isn't it?

samuel··on Forcing the CPU affinity can make a monothreaded process run 2-3x faster
Yes, it does. Read this: http://mailinator.blogspot.com.es/2010/02/how-i-sped-up-my-s... which it's a deeper take on the subject.
samuel··on UsesThis: Rob Pike
Which it's far more interesting, though.
samuel··on Python on Android? First impressions of Kivy
I have read a bit about this Python on Android, and it seems that uses Android's NDK, which allows to port C/C++ programs to Android. I wasn't aware that this was possible. I thought that only bytecode was allowed for security reasons.
samuel··on Python on Android? First impressions of Kivy
I don't understand exactly how this works. You have an Python API for controlling the UI, great, but... can you use the full Python capabilities and expect your app to be portable? If yes, How it works? Is the app compiled to Dalvik bytecode when ported to Android for example? Are you restricted to pure Python modules or something?
samuel··on Google Voice lost my business number. How I got it back, and what I learned.
Brazilians speak portuguese...
samuel··on Numba: NumPy-aware optimizing compiler for Python
Just asking... How it would compare to PyPy's RPython?
samuel··on Why Crisis in Spain This Week Became More Important Than Greece
I'm very surprised about your experience. Unemployment hasn't hit that hard the IT sector,and finding good people ain't easy, but people willing to work on IT? There are plenty and doing very long hours...
samuel··on Why Crisis in Spain This Week Became More Important Than Greece
You can't hire doctors for 1000€(18-20keur/year gross). The lowest paid doctor working for the public health system gets 42keur/year. That's very low, even portuguese doctors are better paid, but that's nowhere near 1000eur/month.

You can hire entry level programmers or engineers por 18-20k, but experienced ones will cost you 25keur or more, and probably you can get better price/quailty ratio in Eastern Europe.

samuel··on New courses added to Coursera (Humanities, Medicine, ...)
All courses on a single page: https://www.coursera.org/courses

I see some overlap among the Algorithms classes: Algorithms I,II from Princeton and Design and Analysis of Algorthms I(there will be II?) from Stanford. I don't think that's a good thing... what's the point?

samuel··on Advice From An Old Programmer
I have known people who started as programmers and became highly valued domain experts, so it works in the other way, too.
samuel··on I’m an Engineer, Not a Compiler
That's no the same at all!! 'synchronize' and 'synchronized' is part of Java's concurrency model. Every midlevel Java programmer should know that every Object has and intrinsic lock, that you can achieve mutual exclusion among threads using that reserved words... even if they can't recall which one is for methods and which for blocks.
samuel··on World's Largest Wi-Fi Network Keeps Passwords in Plain Text
You say it's _unnecessary_ and "there's high chance of someone accessing the password". Under that premises, obviously, it's foolish not to use one-way hashing. Mine is that may provide value and there are sensible ways of mitigating the risk, miles away from accessing the data directly from your application, by using software and hardware designed and implemented by security professionals. That's all.
samuel··on World's Largest Wi-Fi Network Keeps Passwords in Plain Text
With a hardware device as a smart card.

Everyone here implies that passwords are stored in just another table of the database. There are other more sensible scenarios. For exmaple: authentication servers which talk to the front end using CHAP, well behind internal firewalls and with dedicated hardware which holds the private keys and encrypts/decrypts the data.

This has been discussed before. The ability to recover passwords has bussiness value, so at the end its a tradeoff between risk and money.

samuel··on 6 month read-through/discussion of Gödel, Escher, Bach starting 1/17 on Reddit
Could you elaborate? I read it this summer, and while I found that the glue between the chapters was a bit weak(I think the central theme isn't strong enough, no wonder he prefaces the 2nd edition trying to explain what the heck the book is about), it was a pleasure to read. I believe I had an intuition for Gödel's proof(which I have already forgotten), while I probably never have had the guts of trying to understand the real thing.

So, you mean "awful" like, at some level of Math/Physics the whole thing seems fuzzy and inaccurate or just "awful" even for non Physics Phds.
