Questions

I've always preferred sites that allow you to create the question and answer yourself

Agreed. I have long wondered why there are prepared questions at all. When you write the question yourself, it can be made to relate to a personally memorable event or fact, which is easier to remember and far less likely to be discoverable by an attacker than something like mother's maiden name.

Russia will fork Sailfish OS to shut out pesky Western spooks

Boffin

Re: What about the toolchain?

Do you recompile all of the libraries going into GCC/etc. from source? Do you recompile all the compilers from source? Do you trust the underlying OS?

When the source is available, there is a verification method for the toolchain: Diverse double compiling, described by David A. Wheeler here: http://www.dwheeler.com/trusting-trust/

The general idea is to use multiple independently developed compilers as a cross-check. It is not plausible that they are all subverted the same way.

Note that this verification is possible only if the source is available, giving open source an edge in trustworthiness.

All-Russian 'Elbrus' PCs and servers go on sale

MacroRodent
Silver badge

Will the real instruction set please stand up?

The Elbrus 4c used in the PCs and servers is said to support two instruction sets: very long instruction word and SPARC. It's also said to be capable of x86 emulation, and to run Linux natively, after one performs binary translation.

This is confusing... what is the real instruction set in it, homegrown, SPARC, x86 or ARM? After googling links for Elbrus 4c (hampered by my lack of Russian skillz), the most likely answer seems the homegrown VLIW, with some emulation support for x86. Sounds just like the plan that worked so splendidly for Intel Itanium... The native VLIW code might not be too slow, despite the low clock speed, provided there is a good compiler, but then all software has to be ported, so it is likely most users (if any...) will use it as a slow x86 replacement.

Elbrus by the way seems to also have been the name for a line of Soviet mainframes.

Overcoming memory limits in Spectrum-only solution

2) Memory limitations. The symphony is over an hour long, so can't be crammed into 48k of memory, especially in BASIC.

If a sufficiently large supply of Sinclair Spectrums can be assumed, the memory problem could be solved by using a number of them for storage. Some Spectrums act as "conductors" that issue playing commands to the "orchestra". When conductor #1 reaches the end of the score in its memory, it "passes the baton" to conductor #2 which continues where the first left off, and so on....

Re: maglev is the way to go

This becomes less of an issue if the train is in a tube or tunnel (the proposed track between Tokyo and Nagoya is 80% underground!)

They should dig it all the way, and also evacuate (as far as practical) the air from the tunnel. That would allow it to go even faster (1000km/h ?).

JavaScript CPU cache snooper tells crooks EVERYTHING you do online

Re: And Another Thing

Assumption - I am running a browser in a VM. The exploit can tell an attacker about anything else inside that VM but cannot "see" outside it.

Actually, the isolation breaks down because the CPU cache is shared by the VM, the host OS and other VM:s. What gets difficult is cache-mapping keystrokes that do not go into the VM running the snooper, but I would not be surprised if some really smart boffin finds a way around this, too.

People seem to be forgetting that Apache had a DoS based on the range header back in 2011 as well. Windows isn't the only one that has issues.

That bug killed only the user-level Apache server program, not the OS it was running on, and did not lead to any remote exploit. So it was much less serious, thanks to keeping the http server out of the kernel.

Life after Nokia: Microsoft Lumia 640 budget WinPho blower

The size obsession

So this too is larger than its predecessor.

The other day I was looking at a shop what was on offer in case I need to replace my Nokia Lumia 710 (mostly works well, but the browser is dated and is starting to have problems with modern web sites, and the camera is not too great), and was baffled by the large size of the phones, no matter which vendor.

I need my mobile phone to be mobile. The 710 is about the largest size that comfortably fits into my trousers' pocket, and it also has a nicely rounded shape. But all new phones with comparable features are larger, and many have sharp corners or edges. Are they really mobiles? I really would like to have a modern phone in a Lumia 710-shaped shell. Maybe I have to wait until the big size fashion passes.

Gross problems

" eventually going to take humans on the surface of Mars "

One problem here is that taking humans to Mars will almost certainly contaminate it with Earth microbes. (Where do the astronauts put their poo? They will certainly not take it back to Earth, for cost reasons). It would be safer to look for life with probes, which are easier to sterilize (and don't poo).

Re: LTS?

"You upgrade RHEL by nuking and installing from scratch."

Uh? This may be needed on major version jumps, but minor ones like 7.0-> 7.1 are upgraded in place.

Anyway, in corporate environments, IT doesn't want to hear anything about rolling releases in either Windows or Linux. Systems and in-house apps standardize on, say Windows 7 and RHEL5 for years, and major upgrading (apart from "patches") is done only when the disadvantages of sticking with the old start being painfully obvious. If Microsoft thinks they can dispense with clear versioning, then they will have trouble with the corporate market.

Finland and Scandinavia

doesn't share lingusitic or cultural traits with the three Scandinavian countries

Linguistically? no, Finnish is not related to any Germanic language, but note that about 5% of Finnish citizens have Swedish as their mother tongue, and the language has an official status here. Culturally, Finland is very similar to Scandinavian countries because of the long shared history. After all, for hundreds of years Finland was part of the Kingdom of Sweden. We also have the same majority religion (Lutheran).

So the connection of Finland with Scandinavia is much more than "just happens to be in the neighbourhood".

Foot-shooting

Finland is said to enjoy strong legal protection over government surveillance of data, particularly when compared to neighbouring Sweden.

That is the current situation, but in a fit of incomprehensible me-tooism, officials now want to change that and allow mass surveillance of the net. Pure stupidity. It would not really help with security (baddies can always find a way around such wiretapping when aware of it), and would remove one competitive advantage in the data centre business.

Re: Old update files

If you compress your program files, however, the whole file needs to be read and decompressed before the handful of pages you were interested in can actually be used.

Not necessarily. If using a transparently compressing file system along the lines of DoubleSpace, a file consists of a number of compressed blocks. You can access randomly something within the file, and the file system figures out which compressed block holds the data you are interested in, and uncompresses only that. DoubleSpace actually worked at the level of blocks, not files, in order to support an unchanged FAT file system on top of it. What FAT thought of as an allocation block was compressed and stored in from 1 to 8 (or was it 1 to 16) smaller blocks, depending on how much the block could be compressed.

Decompression is fast

There's another 1.5GB to 2.5GB to be saved with compression of system files, but Microsoft says it won't put the squeeze on unless it can be done “ without compromising human-perceivable system responsiveness.”

Huh? Even in Pentium I days, compression&decompression was fast enough so that using "doublespace" or similar was feasible. What time the compressor took was more than made up by the reduction in disk I/O. (Personal experience, used doublespace to get most out of my 500Mb disk drive). Nowadays the gap between CPU and I/O speed is even larger, even on low-end gear, so this should be a no-brainer.

Watery solar system

"Liquid water outside of Earth is very rare indeed, "

Not sure if we can say so any more. We now have strong evidence of three moons having ice-covered oceans (Europa, Ganymede and Enceladus), and there might be even more. Suppose we eventually find most of the liquid water in the solar system is not on Earth...

Several old sci-fi stories revolved around the idea that water is very rare outside Earth (like the TV series "V"(1983) where the aliens came to steal Earth's water). They seem quite dated now!

I never said _all_ large distros, just _enough_ of them. Including the most commercially significant Red Hat (and its derivatives), and SUSE/OpenSUSE, and now it seems also Ubuntu. Sure there will be non-systemd distributions, which is fine, in fact desirable, to avoid monoculture. But it is now clear that those who work with Linux in their day job (like me) just have to learn the ins and outs of systemd.

Re: Blame Microsoft for this

Once Microsoft decided they wanted to improve boot speed, some Linux people started worrying about it too, not wanting Windows to be able to boot faster than Linux.

Boot speed is important in many cases. Think cloud where you might set up a server very frequently. Or an embedded system where you want the device to start working as soon as possible after being turned on. (I just hate it how my shiny new flat-screen TV takes more time to become viewable than the old B/W valve-based TV from my childhood! - that at least had a good excuse for being slow: all the valves had to warm up first). Yes, SSD makes handling lots of small files more tolerable, but not having them in the first place is faster still. Another problem with traditional init is the large number of process launches that happen while processing the scripts. Process set-up eats CPU. Systemd avoids this, too.

Re: read around...

(The logs and config may not be an issue with systemd if it has a decent text-mode viewing program - I honestly don't know!)

journalctl gives you pretty much what catting the log file gives. It also has various options for filtering the output, or printing in reverse. Still learning my way around systemd, but it clearly seems to be the future: enough large distros have decided in favour of it, so one either has to get used to it, or switch to some other OS (if you want BSD, you know where to find it), or some niche Linux distro. (No doubt holdouts will remain for a long time).

One theory I have read in some places blames the lack of Martian magnetic field, which allows particles from the Sun to blast away gases from the upper atmosphere.

The Gemalto hack is the product of poor use of cryptography that requires the private key exist somewhere other than on the SIM.

Remember that back when GSM was designed (1980's), mandaring public-key cryptography might not have been feasible. The first GSM phones had very little processing power. We are lucky to have any cryptography at all in the spec, some countries still force it turned off or weakaned in their networks.

Re: The 60's and computers...

The prof introduced us to the instruction set of the year old intel 8008 and we ran the code on an 8008 simulator running on a CDC 6400.

At the Helsinki University of Techonology we had an actual 8008 machine, very obsolete even then in mid 1980's, but still used for some student exercises. We were to write a little program by hand in hex, for and burn it into an EPROM chip, and run (the simple 8008 machine had no other storage devices). I must admit I cheated a bit: I used a 8080 assembler (running it inside a CP/M emulator in a PC, a set-up I already had around because of other interests), and avoided those instructions that were not available (the 8008 instructions were a sub-set of 8080).
