It has been known for a long time that ads are a primary malware vector, this is the reason many sane people block them.
That is not the primary reason why I block ads. I block ads because I can't stand all the dancing, jiggling, flashing, gray overlays, slowdowns, green links, and noises, when I want to read something. If I incidentally block all the ads, well, I don't have the time to make my own ad block list that blocks only the bad ad providers. I tried it before, and I'm not convinced that there are any benign ad services.
With 3G cellular common, and with 4G cellular being sold at a tremendous rate, I'm frequently seeing people with more cellular bandwidth than land line bandwidth. Most people don't need their neighbors to open their WiFi to get high speed Internet.
In Catholicism's infancy, it was technically legal as a sect of Judaism. If you pushed it at Jews, you might get stoned, but it seemed harmless to others. Then Nero made it illegal, so you might "leave the church" by getting executed. But it wasn't until long afterwards that the Catholic Church became so harmful.
Windows 7 is stable, usable, and a sufficient progress over windows XP. WIndows XP dominated the last 10 years, and my prediction is that 7 will dominate on PCs in businesses the next 10 years.
Windows 7 can't dominate that long, and it really shouldn't. I'd go more insane if it did.
The painfully prolonged dominance of Windows XP is simply due to the failure of Vista. That had Microsoft committing to support XP until the middle of 2014, almost 13 years after it shipped. Windows 8, though, is not such a terrible failure (at least it shipped on time), so Microsoft is only committing to support Windows 7 until 2020, 10 years after release.
As with any version of Windows, some companies will use XP and 7 long after it's prudent to do so. But the majority of desktops should switch long before the end of the extended support period.
In the physical world, there is NO SUCH THING as perfect security. You can't design a setup that someone else cannot overcome We all accept this as part of every day life. However then when it comes to the virtual world, to computers, geeks seem to think things should be perfect.
The difference is that, in the physical world, we start with materials that we do not fully understand. I don’t mean that it’s too complicated, but that the rules have not even been discovered. For a well-known example, Quantum Mechanics still hasn’t been reconciled with General Relativity.
Not to mention, in the physical world you can afford to cut corners because, realistically, who is going to check the security of the 4th stud next to your bedroom, but in software, everything will eventually come under attack.
More terrible timothy videos. The editors continue to post this drivel on the front page.
Would you rather have timothy running around making terrible videos, or timothy posting stories? I think I like Slashdot better with timothy away from his desk.
I "failed" one of these interviews because my implementation updated the left-hand side of a loop condition, and the kid who was interviewing me didn't have the listening skills or mastery of basic algebra to understand that can be equivalent to updating the right-hand side.
And I'm sure Google is glad to be rid of you. This particular interviewer might have been a bit too obsessed with that aspect, but code style is apparently very important at Google. If you can't code for other programmers to maintain your code, then you shouldn't be at Google.
Just the best option with an actual chance of winning, which is practically the same thing.
And who decided that these particular idiots were the ones with an actual chance of winning?
So far, from the limited times I was paying attention, my most ridiculous experiences were in the Democratic primary of 2004 and the Republican primary of 2012.
In 2004, Howard Dean had enough personal conviction to yell out his passions. Suddenly, he's labeled a lunatic, no chance of winning. Let's go with the silver-haired and tall John Kerry. Never mind that he has no positions worth writing about.
In 2012, Ron Paul was immediately labeled The Other and given no chance of winning. Even when he won 2nd place in Minnesota and Maine, it was treated as an anomaly, "The Other" has won 2nd place, not a real candidate with a name. Let's go with the steady-voiced and rich Mitt Romney. Never mind that he has no positions worth writing about.
Schlock has become a lot more kid-friendly since Tayler quit his job at Novell and now works surrounded by his children, but it's still entertaining. And he has kept its schedule for a pretty long time. Several other webcomics of that age gradually turned to weekday only, to Monday-Wednesday-Friday, to once weekly, but Schlock Mercenary keeps on updating every day.
Girl Genius has pretty good art, but what I like best is its large ensemble of delightfully inhuman characters. Every time I find a new favorite character, the Foglios introduce another crazy awesome character.
Gunnerkrigg Court doesn't have the very best art, but it's gradually getting better, and the story is intriguing.
xkcd is a comic by a nerd about nerds being nerdy.
I can hardly believe that, so far, nobody mentioned Qubes OS.
In the theoretical sense, security is possible. It's just very hard. Especially if you want to spend your time doing something other than building a secure computer system.
In practice, most people live with a reasonably amount of security by installing a reasonable alternate OS such as Debian, not installing unnecessary software such as the Java plugin, and regularly installing security updates.
But if you really want security, what you should be doing is isolating, isolating, isolating. If a program has no business using a resource, then it should not be possible for it to access that resource. Qubes is one attempt to do this while preserving application compatibility, by having applications and services isolated to their own virtual machines. Even the network card drivers are in separate virtual machines.
For maximum security with Qubes, you really need a processor with support for VT-d, such as a selected subset of Nehalem and better processors, but the AppVM security mechanism at least should work.
I need a document from scribd (why that is blocked I'll never understand...)
The McAfee block thing tells me that Scribd is a piracy website. Scribd hosts user-uploaded documents, and some of those documents are copyrighted by various companies.
But the upside is, this company could be (in effect) a research and development powerhouse.
Ah, I remember the days. The tail end of them, anyhow. On the one hand, AT&T was a major sponsor of research. On the other hand, they had a low tolerance for innovations in communication that did not come from them. Remember Carterfone? There's a reason the Internet was not developed by AT&T and their friends at the ITU.
Back then, long-distance phone calls were rare, and overseas phone calls were shunned for their huge expense. There's a reason the corporate masters of AT&T decided to hang onto the long-distance business when they were broken up. But with deregulation, long-distance phone calls have become affordable, and we don't even think twice about calling across the country.
I'm not sure what would have been better. On the one hand, the Internet has been hugely innovative. On the other hand, 2001 was supposed to give us video phones from AT&T, but the proliferation of standards (H.323, SIP, AIM, Skype, Jabber, FaceTime, et cetera) has certainly not given us ubiquitous video calls. I guess I could console myself with the thought that AT&T would have made video calls so expensive that I wouldn't have been able to afford it, anyway.
Yeah, like that's worked out so well for us in the past. Publishers create the worst kinds of DRM. At least when I get and Xbox/Wii/PS game... I know that I can buy a game, take it home, and play it.
You mean, you can buy a game, bring it home, and then leave the console alone for half an hour as it installs updates. Or is that just the PS3?
...prevent any parts of it from being used together with non-free software
Sounds similar to arguments against a stable driver interface for the Linux kernel.
That one was for a different reason. Linus is a "pragmatist," and he doesn't believe in Stallman's quest to turn all software into free software.
Stallman wanted to prevent people from using GCC with a non-free optimizer or whatever, because he didn't want people to depend on that non-free optimizer to make a practical system.
Linus wants to retain his own freedom to modify the parts of the kernel that he plays with the most. Linux already has a stable userspace ABI, but a stable kernel ABI means committing to a particular behavior forever. Preventing non-free kernel modules is just gravy on top, because non-free modules lead to crashes that are impossible to fix. That's why adding a non-free module immediately turns the kernel into a Tainted kernel.
Especially if your house is big enough to require more than one air conditioning system, it's convenient to have them on a network. Not necessarily so you can control them from the Internet, but so you can control them all from one place and turn them off when nobody's at home, to save energy.
Of course, once you have them under digital control, you could add things like schedules and remote monitoring.
Even though my linux desktop machine runs for long periods without needing rebooting, there are exceptions:
My several year old Pioneer television runs linux. It crashes and reboots if I change HD channels more than 5 or 6 times.
My roku box needs to be rebooted from time to time.
So does my android phone.
All those are also unlikely to be running EXT4. They store the system on flash and use SquashFS, JFFS2, or YAFFS2. The ones that use eMMC might use EXT4, but Samsung just donated F2FS for that use.
"Bingo, I would wager that most households use wireless only now, since wireless only devices are becoming so popular. I just bought a house...not one inch of ethernet in the place. I don't know about you guys...but that would drive me crazy to make all my desktops wireless!"
Same here. My house was built in the 1950s. Guess they used mostly wifi back then, too.
They did use WiFi, of a sort. Except it wasn't branded. They called it face-to-face communications.
Schools are short of money because students don't get a vote and votes turn into money. It's a bad consequence of finding education to be a right and that means it has to be supplied by government. Government money follows votes. A family of 5 gets no more votes than a family of 2. Which wants the better school? But the votes by families of 2 are against more money for schools.
Money doesn't follow votes. Votes follow money. People tend to vote for whoever spends the most, meaning advertisements or special favors. Politicians afford to spend more on advertisements because of campaign contributions. A lot of the spending in education is given to unions to spend on politicians' campaigns. To be a teacher in a public school, you're required to donate some of your pay to the teachers union, whether you join it or not.
Schools are not short of money because we aren't spending it. We in California pay some of the highest amounts per student in the world, and, on average, we're getting pretty mediocre results. Religious schools seem expensive because parents have to pay for them, but they generally spend less per student than the public school system, and get better results. And they give scholarships or vouchers for church members. The amount of money in the system is not the primary problem.
I think there are a lot of things wrong with public schools. Unions that fight every step of the way against evaluating teachers by performance. Unions that fight against school choice. Unions that use the specter of uncaring parents to punish parents who try to give their children better opportunities. Boards of Education (typically stuffed with members of teachers unions) that purchase the latest fads from the education colleges instead of evaluating curricula. The resistance to evaluate and expel students, because expelled students would decrease the school's budget. Administrative overhead to deal with all the regulations.... It looks like most of the problem is dealing with the unions.
The Trinity GPU is based on proven Radeon cores, why do you expect it to be buggy? Please explain.
You're joking, right?
ATI drivers have worked hard and earned a reputation for being buggy. On my Windows 7 computer, every single blue screen has been in the Radeon driver. The Linux kernel people refuse even to diagnose crashes in the Linux kernel if an ATI or NVIDIA driver is installed, because they make the system less stable.
NVIDIA have had a reputation for better quality, but they're gradually losing it. Intel sponsors relatively stable open-source development for the graphics that they ship, except for the Atoms with the horrible PowerVR graphics. Those chips don't even support Windows very well.
Intellectual Ventures has done harm to a lot of people who are actually making things to benefit the public, and what do they have to show for it? Flashy tech demoes and dubious press releases.
Want goodwill? Why not start by doing something good? You get goodwill when malaria rates are actually impacted by the fancy laser shows, when carbon emissions actually go down because of the nuclear reactors. Not before.
It still wouldn't excuse all the damage caused by the patent trolling. But, hey, the robber barons managed to reverse their reputations with their philanthropy, and Bill Gates now has a legion of supporters who excuse his past sins with his current generosity, so I'm sure Intellectual Ventures can at least appear to be good.
Google sucks because they're only showing results for companies willing to pay to be listed. And the listings are filled with companies of questionable provenance and security.
Amazon sucks because their search engine is the worst. Sure, if you want to buy a specific book, it's fine. But search for a type of product, and they'll give you a lot of results that do not match the search terms, and they'll price sort based on Amazon Marketplace vendors that charge $0.01 for the product and $100 for the shipping.
The best is if I can go to a specialized store, such as NewEgg, and pay using PayPal, because then I limit the number of evil companies that have my credit card. Otherwise, if I know exactly what I want, then Amazon has my credit card on file, too, and has good shipping. Too bad I don't know the other industries very well.
I'm still running Vista, which was slated by just about everyone.... I've had about 6 months uptime on this system, which I use for gaming, work, surfing, etc.
How many viruses do you have on that machine? There's no way you can install all the security updates for the past 6 months without rebooting several times.
Not to mention all the stability problems that come from running closed-source software. My Windows 7 computer rarely goes above 2 weeks without the ATI driver crashing so badly that it needs to reboot.
A school will keep the Math textbooks for an other 5 years, Algebra hasn't changed much, new books is just wasting money, just so kids have a shiny new textbook.
If only it were that simple.
Schools change the materials according to the latest fads and brain farts from the educational establishment. In San Francisco, the primary schools recently changed to Everyday Mathematics, created by the University of Chicago. The schools are getting better at teaching it, now that they've been using it for a few years, but it's still a horrible curriculum. The best teachers provide their own materials, or hang on to older textbooks.

In catholicism's infancy it was not so easy to leave that church alive either.
Are you joking? It's hard to tell whether you're wrong or making a subtle historical point.

In contrast, software is built from pure logic. As Edsger Dijkstra put it, The automatic computer is our first large-scale digital device The animistic metaphor of the bug that maliciously sneaked in while the programmer was not looking is intellectually dishonest as it disguises that the error is the programmer’s own creation. He says a lot of more interesting things in that lecture. In principle, everything that a program does can be derived from a careful reading of the text, because all the rules are well-defined.
Not to mention, in the physical world you can afford to cut corners because, realistically, who is going to check the security of the 4th stud next to your bedroom, but in software, everything will eventually come under attack.
