Microsoft Announces Windows 10

Megol Re:Better call it Windows 11 (516 comments)

And? The reason for the existence of an internal version number is for internal use - it doesn't signify the extent of changes between versions.

Microsoft Announces Windows 10

Megol Re:Skipping a version number (516 comments)

NB that the major version number doesn't increase even for extensive rewrites of the core system. The reason is allegedly for compatibility.

BlackBerry Launches Square-Screened Passport Phone

Megol Re:WTF? (189 comments)

There isn't any "data-only" USB cable! There are 3 connectors theoretically needed for communication: Ground (signal reference), D+, D- (signal) and in practice the power connector (+5V) is needed too. Just having the signal connectors (D+ and D-) wouldn't be of any use as it would be impossible to even detect that a unit is connected!

Now his charger may have been too weak and the BB simply required more current to charge than it could deliver.

Why You Can't Manufacture Like Apple

Megol Re:Manufacturing (408 comments)

The benefit of laser cutting is that it is predictable and repeatable.

That doesn't mean doing it is trivial at large production scales.

Here I'll stop. Because it's true and because I had an explicit mention of that case in my OP!

If you want to mass produce things in the order of Apple products are mass produced - well then it will be tricky. But the startup expecting to do that _will_ fail due to disconnect from reality.

If you want to produce lesser amounts with a very high finish it is possible and have been done before. Lesser here can still be a huge amount of products.

HTC, Samsung, Asus and Sony to mention a few. Have you never used anything except Apple?!?

Why You Can't Manufacture Like Apple

Megol Bullshit. (408 comments)

Simply as that. CNC machines aren't made by only one company, laser drilling isn't really rocket science, packaging have been done better etc.

Surely one can expect that a certain level of finish requires more money than a lower level one - but that is only natural.

Now if the article was about startups that expect to sell _as_many_devices_ as Apple with the same level of finish it could be true. And ludicrous!

New Release of MINIX 3 For x86 and ARM Is NetBSD Compatible

Megol Re:High reliability? (93 comments)

That doesn't change the fact that L4 _never_ had a 1ms context switch time. Not even on a 486 was it never that slow, the kernel entry cost was 200 clock cycles.

The L4 kernel have always been in the front of pure IPC performance, it is as simple as that.

Also for other people reading this there are a number of features that enable even faster microkernel performance today, the syscall/sysenter instructions makes entry to kernel mode less expensive than the traditional interrupt handler (which due to x86 semantics are often slower than necessary) and address space identifiers makes flushing of L1 cache unnecessary.

New Release of MINIX 3 For x86 and ARM Is NetBSD Compatible

Megol Re:A microkernel-based OS that 'just works' (93 comments)

Magic bullet? There never are any magic bullet for complex systems.
A microkernel is the realization of best practices for security systems and - dare I say it - follows the original Unix philosophy.

Do one thing (IPC) and do it well (ensure security guarantees are kept). Keeping the critical code small makes it easier to verify code in both the practical and mathematical sense.

New Release of MINIX 3 For x86 and ARM Is NetBSD Compatible

Megol Re:High reliability? (93 comments)

10 times faster IPC than L4 on x86?!? That requires user level IPC like done in Barrelfish and ZIMP ("ZIMP: efficient inter-core communication on multi-core machines" ).

Got any proof that the Minix IPC performance is so much better than what is commonly known as one of the most efficient IPC implementations in existance?

New Release of MINIX 3 For x86 and ARM Is NetBSD Compatible

Megol Re:Drivers as processes? (93 comments)

Depends on how it's done. It's possible to have replicated data fully or partially so that things would just work with a little bit longer latency.

Of course there will always be a failure mode in any system however it is possible to push it to very unlikely scenarios (like the data center being the target of a nuclear attack). The cost is in most cases not engineering work IMHO but runtime performance, reliability will cost at least a constant factor for all critical operations. Which is worth it (still IMHO).

Megol High reliability? (93 comments)

Does anybody know what exactly is novel in the Minix 3 approach? Microkernels (or small macrokernels) with restartable drivers are well known and already used in the real world.

Extent of Antarctic Sea Ice Reaches Record Levels

Megol Re:It's getting hotter still! (635 comments)

Let me count the ways you are wrong:
. Wrong pole
. He didn't say that
. Even if he did (which he didn't) it wouldn't mean shit
. Most climate scientists didn't agree with what he actually said (which isn't what you claimed)
. Again even if the statement he said would be falsified it changes nothing in the science and models
. You doubt something that is proven to exist which is frankly a very stupid thing to do
