Are Computer Crooks Renting Out Your PC?

setagllib Re:Are Computer Crooks Renting Out Your PC? (208 comments)

The article itself mentions that many of these machines belong to businesses, where Linux has a higher share. And while servers are more difficult to attack in general (well, they don't have Adobe Flash or Reader...) they make better targets, and servers are where Linux is the higher profile target. Its heterogeneity and timely security updates save it a lot there. We can expect more effort given to attacking Linux over time, but for sure it will *take* more effort.

"Midori" Concepts Materialize In .NET

setagllib Re:Wasn't Windows 95 and 98 built from the ground (106 comments)

Managed code by its nature can work WITHOUT memory protection at all.

How did you think the "management" worked? Either you trap each pointer access manually (and maintain all of that state and overhead), or you use a memory management unit to do it for you (and accept the cost of traps and context switches).

The very best that a VM runtime can do is infer that a class of access is impossible and thus exclude traps for it. This only works in extremely limited circumstances, and still requires code to be correct. It in fact makes profiling really difficult - and performance is the whole problem in the first place.

Multicore Requires OS Rework, Windows Expert Says

setagllib Re:Energy efficiency will do it (631 comments)

You have a very strange definition of "core". Do you mean that any ASIC or FPGA is automatically a core? More ambiguously, what about an FPU or GPU? If a mobile phone has "half a dozen cores" then a PC has hundreds.

Ubuntu Gets a New Visual Identity

setagllib Re:Window control buttons on the left? Bad. (683 comments)

You can close (and minimise, maximise, etc) windows by right clicking on the title bar or even the task bar's button corresponding to that window. This is consistent in KDE and several other window managers.

Apple Discontinues ZFS Project

You really need to subscribe to the mailing list. The rate of development is only growing -- it's just now moved on to a lot of smaller features and improvements, now that most of the work is already done.

Windows 7 On Multicore — How Much Faster?

setagllib Re:Not Really (349 comments)

I disagree - user-mode code, whether it's separated into threads or processes, still relies very heavily on kernel scheduling decisions. It may sound simple enough, but if you study the decisions the kernel has to make (such as which thread to wake first, from a set of 8 all waiting on the same semaphore), you can find lots of ways to get it wrong. We now take it for granted because thousands of man-years have been spent on solutions.

Element 114 Verified

setagllib Re:Why the need to 'discover' the elements? (142 comments)

Leave both in a vacuum and see which one lasts longer. There's a very clear definition of atomic stability that is markedly different from chemical reactivity.

PulseAudio Creator Responds To Critics

setagllib Re:Useless (815 comments)

Ok, what? It definitely works as a daemon. But even if it didn't, what's the issue? If you have a dedicated headless MPD server, you gain nothing by using Pulse. If you have plenty of desktop applications that all want sound input/output, Pulse solves basically everything.

Firefox Disables Microsoft .NET Addon

Apple's Grand Central Dispatch Ported To FreeBSD

setagllib Re:GCD also replaces most synchronization / lockin (205 comments)

If you're creating a serial queue anyway, you no longer have parallelism. If you have multiple serial queues, you may as well have had multiple threads with no interlocking between them. This is just yet another API to do what competent parallel system programmers have been doing since the first thread.

In Trial, Kindles Disappointing University Users

setagllib Re:People who write in textbooks... (247 comments)

I agree. The best students I know don't even buy the books, let alone write in them, because they're actually using the material in practice (hobby, job, overkilling lab work, etc.) and internalise it better than note-taking and highlighting ever could. They look lazy until you see what they can actually do.

Mainstream Press "Cringes" At Win7 Launch Parties

setagllib Re:First post... (830 comments)

In all fairness, when did Microsoft ever have fanfare? Informed computing enthusiasts were sick of Windows after 10 minutes, opting to at least diversify into Apple and free Unix, and nobody else even knew there was anything other than Windows, and treated it as part of the computer.

Now that people realise they have choices, Microsoft is scrambling to do what it never had to do - actually market its operating system - and has shown all of the competency of a high school dropout.

Intel Core I7 For Laptops — First Benchmarks

setagllib Re:battery life? (196 comments)

Using Linux' frequency controls, the Turbo just increases your maximum multiplier by 1, and that's it. If you're configured to maximum performance, you get the Turbo, otherwise you don't. Maybe it's more complicated in Windows, but it's clear that the feature is controllable from the operating system.

Linux Kernel 2.6.31 Released

setagllib Re:Linux audio (374 comments)

The real fix would be to make PulseAudio use OpenAL optionally, so that cards that have accelerated mixing can be made to use it. I don't see the point though - not only are modern CPUs more than powerful enough to do it in userspace, they can't possibly have per-card defects while doing it.

Now that we do have PulseAudio it's best to trim as much fat and necrotic code from the kernel as possible. If the remaining realtime issues can be resolved, for which there is much experimental literature, it'll be perfect.

Microsoft Letting Patents Move To Linux Firms

setagllib Re:There is no secret patent based plot to kill li (228 comments)

Linux and open source in general are a theoretically infinite competition to Microsoft. After a big spike in proprietary models, the trend of all software industries is now towards more open standards, more open software and smaller companies offering small sets of products that together solve big problems. This is exactly where open source most naturally thrives, and it's the exact opposite of how Microsoft has always operated - one vendor, one set of products, nothing open. Microsoft's executives know this, they're not stupid, so they're trying to hold back the trend with patents and faux-open standards like OOXML. It's like trying to hold off a global ice age by burning your house down.

Con Kolivas Returns, With a Desktop-Oriented Linux Scheduler

setagllib Re:Cool, but what does that spec mean? (333 comments)

It's a scheduler term, not a hardware requirement strategy. Leave the tech to the people who know (certainly not me, but Con is epic).
