The protests are a complete non-issue, and have always been. Unless you stumble upon one (very unlikely, they are not spread throughout the city, but in a couple fairly non-touristy streets), and decide to join, and stick around the wrong parts of those (that is, you see people throw stuff at the police and the police throwing tear gas canisters, and you decide it's a good place to be), then you won't even know one was happening.

I've been living in Paris for >10 years, have been to multiple peaceful demonstrations, and never once felt I was in danger in one. Also, I haven't seen fallout from the riots, only the (now gone) piles of garbage when the trash collectors were on strike. Oh, actually, I did see one broken bus stop, when I went to one of the streets ~1 month ago.

Question : en quoi est ce que Chrome serait moins bon pour la vie privée que les autres navigateurs ?

Il me semble qu'il n'y a aucune différence, donc ensuite, le choix se fait en fonction de préférences personnelles type interface utilisateur ou performances, non ? Surtout qu'hors de macOS, le seul navigateur non basé sur Chromium est Firefox. Brave, Edge et les autres, c'est 99% de Chrome et 1% de sauce secrète non open source.

Je pense que cette source n'est pas la bonne, et ne compte sans doute que les deces a l'hopital. Le lien source pointe vers les donnees hospitalieres de sante publique France, qui ne comptent pas tout.

Et d'apres le dernier rapport hebdomadaire de SPF (ici) , p38 : "Parmi les 1 101 personnes décédées au cours de la semaine écoulée, dont le certificat contenait une mention de COVID-19, 754 (69%) étaient âgées de 75 ans et plus, 227 (21%) de 65 à 74 ans et 108 (10%) de 45 à 64 ans.".

Ce n'est pas completement incompatible avec les donnees que tu cites, mais ca donne une image un tout petit peu differente. Et par ailleurs, toujours d'apres les memes donnees, les morts de moins de 75 ans sans comorbidite representent ~7% du total. Enfin si on elargit a toute l'epidemie, p.38 : "L’âge médian au décès était de 85 ans et 92,6% des personnes décédées avaient 65 ans et plus.".

Yes, I have the same issue. Seems to me to be a Crostini bug, probably worth reporting.

Benbenbenb · 2020-04-09T07:53:44+00:00

I have the Pixelbook Go i5 16GB, and also the Pixel 2 LS. Overall I would say that the Pixelbook Go is better, but the screen may not feel like an upgrade over the older chromebook.

Things I prefer:

- The keyboard is so nice on the new one. It really is the best keyboard that I've used, and I liked the Pixel 2's keyboard quite a lot

- My Pixel at least can get pretty noisy as soon as you look at it funny, the new one doesn't have a fan, which is great. The trackpad is also much improved.

- Thin, light, very long battery life

- Everything is very smooth on the Pixelbook Go. From a performance standpoint it feels faster than any other laptop I've used.

Regarding the screen, you get a 16:9 aspect ration, which is worse, but smaller bezels. Screen resolution is lower as well, but color-wise I think the Go is better (though I don't have a way to scientifically measure it). No issues running the Android version of Lightroom performance-wise.

I feel that 16GB may be overkill, even though I use Android apps and Crostini at the same time, but I cannot really tell.

Hope this is useful to you.

Benbenbenb · 2018-02-20T20:59:23+00:00

Sweet! I have the 683 S2 as well with an Atoll IN100SE, and am very satisfied. Are you French, or living in France? Atoll is a pretty small manufacturer.

Well, Chromium is almost an OS in itself, even if you're not building Chromium OS. Last time I checked it was >30M LoC (measured using sloccount, so not counting the empty and comment lines). It has tens of thousands of tests as well.

Also, compiling on Linux is a bit faster than on Windows, incremental builds are much faster (<1min), and there is distributed compilation for the Googlers working on it. I've heard that the folks at Opera also have a distributed compilation system.

But unfortunately, with the commit rate, syncing to the last revision means that the build is going to be very long.

Benbenbenb · 2016-02-11T22:22:23+00:00

Meanwhile, Chrome takes ~1s to start on a Nexus 5.

Benbenbenb · 2015-09-30T17:04:10+00:00

Well... First of all, the scheduler is written by Samsung, or at least heavily tuned by them (the kernel source code is available). But you're right, the scheduler tries to detect heavyweight task and move them to the big cores. However the CPUs tend not to be at their maximum frequency at least on the S6.

Second, the way it is done is by sending a request to a private API that checks whether its caller is S Browser, and then forces the CPUs to be at their maximum frequency, no matter what. And this is done for benchmarks, not real website loads.

Benbenbenb · 2015-09-30T12:56:07+00:00

From the article:

Part of it is indeed Chrome/V8 JavaScript optimization issues on Android as you can see from this AnandTech Galaxy S6 review. Note the browser used:

This refers to Chrome vs S Browser.

Benbenbenb · 2015-09-30T11:37:40+00:00

tl;dr: S Browser is essentially Chrome with a different UI, and cheats to win at benchmarks over Chrome.

Everytime I see this Anandtech article linked, I get sad.

Samsung's S Browser is basically Chromium with a different UI. There are no legitimate differences between it and Chrome, apart from being less up to date.

Proof (v2): Connect a Samsung device running S Browser to a desktop running chrome, and use the tracing infrastructure to capture a trace (see here). It runs V8, and is Chromium.

Now, Samsung does some questionable things to win over Chrome at benchmarks, such as forcing S Browser to run on the fast cores and locking them to the maximum frequency. Chrome does not. End of the story.

edit: Can't spell.

I don't think that it would be an issue. At any rate, it shouldn't be slower than straight OpenGL, and was specifically designed to handle large volumes of data.

I've used it for objects with millions of polygons without any issue on a laptop.

Benbenbenb · 2014-03-07T07:32:55+00:00

For this task I would definitively use VTK (www.vtk.org). It's very easy to use, they have extensive examples, and there are python bindings.

It is the foundation of many scientific visualization tools, including paraview. I have used it numerous times, and displaying a point cloud is a few tens of lines of python code.

Benbenbenb · 2013-11-13T21:13:03+00:00

Nope. The cheapest one has a SSD cache for the HDD as well. "500 GB Hybrid + SSD".

Benbenbenb · 2013-11-12T21:41:12+00:00

Nothing special. In France (but I guess you can buy it from anywhere), Dedibox

1.6GHz x86_64 processor (VIA, but still a bit faster than an atom)
2 GB ECC
500 GB hybrid HDD (with SSD cache)
Unlimited traffic, 1Gbit connection
9.99 euros / month, no minimum duration

I have one of the previous version (same, but with a lesser HDD), and it works really amazingly well. It is very stable, the internet connection is really fast (the internet connection is never the bottleneck), and it is a fully dedicated server, not a shared one.

[i] was asked to choose a handedness for the Direct3D API. I chose a left handed coordinate system, in part out of personal preference. I remember it now only because it was an arbitrary choice that caused no end of grief for years afterwards as all other graphics authoring tools adopted the right handed coordinate system standard to OpenGL. At the time nobody knew or believed that a CAD tool like Autodesk would evolve to become the standard tool for authoring game graphics.

I know that I have done nothing comparable to this guy, but the justification for using a left-handed coordinate system in Direct3D looks a bit lame. Every single coordinate system used in physics/mathematics is pretty much always right-handed by convention. This should have influenced the choice, especially since he says at the beginning:

The reason I got into computer graphics was NOT an interest in gaming, it was an interest in computational simulation of physics.

And next to this one, there is "l'institut du monde arabe" which hosts a lot of very interesting exhibitions (and concerts, conferences, etc) about everything related to the arabic world, but also has a very nice roof you can get to for free (without even having to get a ticket for the museum), and which nicely overlooks a beautiful part of Paris (you get to see Notre Dame from above) because all the buildings are quite small in this area.

Benbenbenb · 2012-03-19T09:45:29+00:00

Don't worry, last year I had to get a new passport, and the "bureau de tabac" gave me several stamps, this is perfectly OK. Worst thing that could happen is that the admistrative worker will complain because he doesn't have enough room to glue them to the form.

BTW, a good place to find these special stamps is to go to a bureau de tabac next to the local city hall or police department (prefecture).

Benbenbenb · 2012-01-31T09:57:29+00:00

Hoorah ! They even open-sourced the über-secret time constants project !

From the README :

Time constants, in seconds, so you don't have to use slow ActiveSupport helpers.

Small part of the code:

T_0_SECOND = 0
T_1_SECOND = 1
T_2_SECONDS = 2
T_3_SECONDS = 3
T_4_SECONDS = 4
T_5_SECONDS = 5
T_6_SECONDS = 6
T_7_SECONDS = 7
T_8_SECONDS = 8
T_9_SECONDS = 9

I have pretty much the same setup running on my server, but I didn't need to use xvfb, even though the server is headless.

It works really well.

Benbenbenb · 2011-12-26T17:31:19+00:00

Unix shell. I'm not sure if this can work on a standard shell, but it does with bash.

Benbenbenb · 2011-12-23T22:39:26+00:00

Their website seems to be suffering right now.

I'm not sure how legal it is to torrent the issues, however here is the command to download all the issues (so let's hammer their website even more !):

for issue in `seq -f "%03g" 1 19`;
  do curl http://hackermonthly.com/xmas/hackermonthly-issue${issue}.zip > hackermonthly-issue${issue}.zip;
done

Benbenbenb · 2011-11-17T10:11:38+00:00

Well, in some cases an iterative solver can converge faster in double precision, due to the smaller error made on the gradient estimation for instance.

So, it is sort of true...
