Software Emulates Organism's Entire Lifespan

keeboo still a long way to go (86 comments)

Don't get me wrong (I think that's really cool and stuff)...

But I wonder what will take to simulate a few amoebas in a petri dish, what is not exactly the apex of biological complexity.
Obviously multicellular organisms are out of question for some time still.

Firefox Notably Improved In Tom's Hardware's Latest Browser Showdown

keeboo Re:Too bad for others (218 comments)

But some people only know how to use a browser, and that is all the do on a computer. (facebook junkies mostly). They fire it up, and stay there for hours on end. Leaks matter to these people only when their machine slows down (Most are not computer literate enough to detect a leak until it gets rather large).

I believe I know a bit more that just using the browser (my first computer had a - then - competent Z80A processor, just to give you a hint --- but who knows, I may be a shameless liar who was a kid when Windows 2000 came in).
And, yes, I have quite a few openened browser windows (today 8, typically 3-4), each with lots os tabs (average: 15? I'm not feeling like counting).

Why do I keep that stuff opened all the time? Because I already leave my machine 24/7 on processing XYZ (usually research-related tests before sending that to a cluster for the real job + the fact I find the fact I may access may computer-and-its-data anywhere anytime very, very, convenient).
Still, that does not explain why the browser is running (why not closing the app before going out?). The reason for that is that I like the convenience of, when returning home, to be able to resume whatever I was looking for / researching on the web. My memory (self, biological sense) is not that great, and it helps me a lot when I minimize the level of intellectual noise so I can focus on what really matters.
Is that a processing waste? Technically, yes, but I do not care. The computer is supposed to serve me (and that includes my quirky habits), not the other way around. Talk to me about computing performance where it really matters, not on my personal computer.

The browser is Chrome, which I use for everything except online banking and certain sensitive accounts. Great browser, its process-per-tab structure works really well to take advantage of my 4-core processor, unlike Firefox (unless something changed? I would love a process-per-tab Firefox).
Back to Chrome: the browser is great and stuff, but it eats a lot of memory. With my previous 4GB RAM I had a miserable life (swap all the time) after a certain point of Chrome upgrades. It seems that the situation only got worse after each new version.

Eventually I upgraded the motherboard and its memory (the processor was fine and stayed) so I got 16GB. And I bought that because it was not worth my time changing my behavior to adapt to my machine's limitations.
Chrome performance improved dramatically, life was beautiful again, then able to go back to things that really mattered etc etc. Still, during some heaving browsing (I like to leave N papers simultaneously opened so I can go from one to another as I like, okay?) I noticed that the CPU consumption increased as well. Do you know when it feels like the software is taxing the memory and CPU caches? Well, exactly that.

I like Chrome, but it became bloated rather quickly (around the 2-digit versions, perhaps?). It was lean and elegant, now it feels just... adequate. And it's not like I really changed my browsing patterns, the thing became a fat pig (well, a multi-process pig, what minimizes the issue a bit). A pity, comparing to the early Chrome versions.

Really, the only thing keeping me from going back to Firefox is its lack of (useful, at least) multi processing. The issue that drove me to Chrome to begin with.

The Leap Second Is Here! Are Your Systems Ready?

keeboo Re:How is this an issue? (284 comments)

When NTP tries to say that it is 12:34:61 and the computer only expects 1-60.

Why only add a leap second, when you can also add a fixed +1 offset to the seconds while you're at it.

Personally I would rather normalize the minute cycle to a prime number of seconds, but that's just me.

Intel Builds On Top of Android, But Hedges On Open-Sourcing Improvements

keeboo Re:Altruism vs profit. (156 comments)

That's what we (professional company paid develops) do.

Bitch incessantly and post as Anonymous Cowards on Slashdot?

I think that by "paid developers" he actually meant "paid developers of proprietary code".

There are people getting paid (directly or indirectly) to develop open source code.
Those are the people who not only earn their living from software development, but also have cojones to have their code exposed to be whole world.
Think about that: any mediocrity of your is made public and preserved for... pretty much forever. One has to respect such professional attitude.

Many of the paid developers are simply listed as "independent individuals" (instead of from company XYZ) while not really being that, for reasons such as:

a) That was an auxiliary project/task for the company/government and it does not care/want to be credited,
b) Auxiliary project/task (as above) for the government, done by a public servant, for a project the government does not want to keep the burden of maintaining its own fork.
Depending on your country (and its government and the way people deal with such situations - the latter being a cultural thing) it may be far simpler for licensing/copyright reasons to just pretend the code was done by the public servant in his own time, instead of dealing with a nightmarish bureaucracy.
c) The developer is independent and the code is generic and may/will serve more than one paying client,
d) The developer is a researcher and the paying part is interested on credits when it comes to papers, books and patents. -- Though, yeah, in this case
e) ... etc

'a' and 'b' happened to me oh-so-many times (though I really wish we had less complicated laws here, so for 'b' to be unnecessary).
I know people in the 'd' case, though not to me: I never generated decent code from research and got funding, both at the same time.
I know people fitting the 'c' case (most have their own small company). Not my case either.

For some reason, I'm unable to get any information linking Diebold ATMs to Linux (is Diebold no longer involved and someone took over the maintenance of Diebold hardware?)

In America, 46% of People Hold a Creationist View of Human Origins

keeboo Re:in other words, 46% of americans are dumb (1359 comments)

If you choose not to believe in God, then that is your choice.

I was not aware that believing in a mystical entity is the standard, and that anything else is deviant behavior for humans.

Granted, I would wonder where you morals come from, and given your post above I can draw some conclusions....

If you need to believe in afterlife punishment and/or reward in order to have moral values...
You have no moral values whatsoever. You're just serving your own interests, and bragging how good you are.

Jack Tramiel, Founder of Commodore Business Machines, Dies At Age 83

keeboo Re:Everyone ignores Commodore (301 comments)

Yep, I remember that my (then new) A500 looked somewhat clunky even in 1990 (such great computer with such a depressing appearance.. oh well) , but it felt well built.

I got bought a A1200 in in 1993 (or early 1994).. yeah, made in Philippines.
It cost a _lot_ to me back since it wasn't produced in Brazil (imported computers were unpayable, really).
AFAIR I paid something like ~950 USD back then for a A1200 with user-installed HD, and that from a (ahem) friendly person often crossed the border, so it was cheaper. -- It's a relief that epoch is long gone.

So, back to the topic...
That A1200 I got _felt_ different from my previous A500, like it was made my a company trying to save every single nickel (yes, I know.. Commodore).
Heck, the A1200s were supposed to come with a non-1970s-looking-A500-like mouse but mine came with that ancient model, except it was not beige but white like the new machine.

That not being enough, my Philippines-made A1200 started to fail after ~1 month or less, in 2 months it was dead (1993's 950 USD was a _lot_ of money in Brazil, so I was rather distressed). Weeks later I managed to find a technician from Rio de Janeiro who bothered to _try_ to salvage that computer, and he managed to fix that after a massive resoldering job on the A1200 board. Back then he told me that "those new Amigas are all having problems" (due to low-quality production).

And about 1-2 years later the keyboard started to fail. My luck is that I managed to get another one from a dead A1200.


I loved the architecture, the software and stuff... But Commodore treated its costumers like trash.

keeboo Re:Everyone ignores Commodore (301 comments)

IMO the NeXT workstations, though clearly based on the Xerox office computer from the 1970s, was far more deserving awe than anything Apple released during the 1980s, including both the Macintosh and the Lisa.

But that wasn't for the masses (actually, given the price tag for awfully underpowered bare models during the 1980s, I don't think that even Macs were as realistic as people like to remember).

For the rest of us, there were 8-bit computers such as C64, Spectrum, MSX etc; and great 16/32-bit machines one could actually afford, such as Amiga and Atari ST.

1.9 Billion Digits: Brazil's Bid For Biometric Voting

keeboo Re:Sounds like (140 comments)

That's correct, and it's the "digital" and "unified database" thingies that scare me to death.

So it seems bad? It's even worse within historic contextualization.

The brazilian government has a disturbing, and increasingly stronger, tradition of imposed culture homogenization and control centralization.
That, so I understand, has roots from an old fear of country desintegration. We have disgraceful examples from a not-so-distant past (1940s, 1950s) when european migrants (most living in the southern region) were forbidden (or strongly discouraged) to publish local newspapers in their language, to teach such languages in local schools and even (that happened to germans descendants) books, if not entire libraries, were destroyed since the material is not in the "correct" language. Brazil had a massive influx of immigrants in the late 1800 early 1900, and yet that fact is, at best, a side note on History classes children attend. It is as it never happened and people simply existed as an cohesive nation.

Nowadays we may go to places where most people are, let's say, of ukrainian origin, have such physical appearance, but do not know anything about their ancestral language nor from which region they came from. Their culture was intentionally destroyed and a "brazilian culture" (being to national culture what Esperanto is to a natural language) was pushed down their throats.

The public administration is extremely centralized, by design. The brazilian "federal system" is not that, except for the name. The states in Brazil have less autonomy than the provinces in Canada (even disregarding Quebec). The brazilian constitution itself has absolute clausulas petreas (entrenchment clauses) on that matter, including absolute indissolubility of the so-called federation.

The fact the brazilian capital was moved to a fabricated city in the middle of nowhere, far from the dangers of popular revolt, says a lot.

Now we have IT developed to levels allowing storage and processing of every single citizen.
And not even that is news. Even IT specialists are not usually aware of the level of information concentration in Serpro.
It's immensely ironic to find intelectualized brazilians bashing the horrendous privacy laws from foreign countries, while oblivious to what is solidly stablished under their own noses.

More recently, the brazilian government realized that, even with all the brainwashing efforts, the economic mid-class suffered a big hit in the 1980s and 1990s and started to get somewhat smarter and, the most worrying, insatisfied.
Meanwhile the upper class have money and never cared about such things. The government is usually friendly, otherwise there's always the option to leave the country.
The lower-class, often uneducated, people is busy trying to survive and know nothing about anything. No danger here either, and any possible enlightening is kept under control with substandard education.
Few years ago the federal government started a brilliant strategy of economic empowerment of its low-class citizens (education be damned, nobody wants the cattle starting to think) with actions which include a program that, in practice, give free money to people (Note: Brazil's economy management improved immensely the last years, but it also had a dumb luck. The last years there's an influx of money clogging the government pipes so, for a while at least, it is viable to do such things).
At the same time the, now inconvenient, mid-class is being crushed by taxes, while being accused of low-class parasitism by clever populist propaganda from the very government. The last years it has been talked about a "new mid-class" with indirect suggestions of damnation/extinction of the former one.

Going back to the topic:
Does it seem likely that this new fabricated, and semi-educated, mid-class will care about privacy issues and concentration of power?
Specially now when the economy is doing so well that huge LCD HD TVs ("HD" = "very good, or something.. need a beer") are selling more than toilet paper?
Of couse not.

In the end the brazilian government with do whatever they want. They can, and they're fully aware of this.
And nobody will care, because it always have been this way, it's always been taught this say, and it's absolutely normal to everyone.

So is the design of things.
Prepare all your fingers to be scanned, and pray that the government do not see purpose for anal probes.

Ask Slashdot: A Cheap, DIY Home Security and Surveillance System?

keeboo Re:Been there, done that.. Here's your plan. (508 comments)

I live in medium sized building (16 floors) and we had a similar dilemma.

We bought one of those cheap chinese OEM CCTV DVRs (sold under several brands worldwide, the real source is a chinese company called Dahua), plus 8 cameras.
Notes:
Considering its price, the DVR works quite well, and has decent quality/framerate (30 fps / camera, 352x240). The bad thing is that the remote client software (optional usage) is Windows-only and buggy as hell.
We considered a desktop PC with a multi-channel vide capture card (it's far more flexible), but it's messier to install/maintain (bigger, with fans sucking dirt 24/7, someone may be tempted to occasionaly use as a desktop PC etc).

We installed the DVR in the entrance room, so the doorman/watcher (however it's called in English) can see what is going on AND we have all the activity recorded in case of need.
Problem: What if, for example, someone steps in with a gun and blows up the DVR? The videos are gone, and a periodic backup will not prevent this, since the most relevant video happened mere instants before, thus DVR-copy only. -- So, for the worst-case scenario (and right the most valuable one to have recorded video), the DVR seemed useless (the DVR has a built-in sync mechanism which is very unreliable, so it's worthless).

The dillema was solved with a free software called Tanidvr (Unixoid_OS-specific, command-line, and specific to that DVR family). Basically, we bought a computer to be used as a realtime backup server, installed in a locked room in a different floor. We also have a (intranet-only) HTTP server in order to easily download the videos, if necessary.
So, no matter what happens to the DVR, we have the video data up to the exact time (delay <1 second) the machine was destroyed.
A backup script was created for video fragmentation, and to recompress the H.264 stream to fit more days into the HD (with a quality/size the DVR is unable to provide).

Well, it works for us.

Why companies need female managers

Men are more analytical; women are better long-term planners.
And understanding that male and female brains develop and behave differently is important not just if you are in the dating game.
It also helps us to hire the right people, improve teamwork and can — to quote part of the title of her talk at the World Economic Forum in Davos — grow a company's bottomline.

Researchers from mining group Rio Tinto discovered the unusual mineral and enlisted the help of Dr Stanley when they could not match it with anything known previously to science.
Once the London expert had unravelled the mineral's chemical make-up, he was shocked to discover this formula was already referenced in literature — albeit fictional literature."
