Proposed Disk Array With 99.999% Availablity For 4 Years, Sans Maintenance

goarilla Re:Naive to say the least. (242 comments)

Most should make it to their second year (>=8640 hours).
In our small 24 bay array I've seen a lot of those bad Seagate ST3000DM001 fail at ~15000-19000 hours.

Why Screen Lockers On X11 Cannot Be Secure

goarilla Re:If it's accessing your X server, it's elevated (360 comments)

I'm not familiar with writing apps for X, but are you saying that every program that displays a window in X can log all keystrokes including in windows that are not associated with that program?

Well try this:
- Find the id of your window of interest (xwininfo).
- Attach to it with xev -id $id

Now that you know ... Ctrl-Alt-Backspace zaps X.

Book Review: FreeBSD Mastery: Storage Essentials

goarilla Re: UFS vs ZFS (75 comments)

But the protection is not perfect. Throw random data into a few adjacent blocks the way a head crash does, and if those blocks happen to be structural metadata, think about how extensive the data loss could be. In most cases, e2fsck and repair damage like that. ZFS can't.

True I've wondered this myself lately with btrfs. Ext? has backup copies of the superblock. Which it uses during repair I presume.
There is no reason ZFS shouldn't have redundant copies of the critical structures. How foolproof is ZFS data protection for normal data and structural data ? Can anyone shed light on this ?

Now fsck utilities aren't perfect and can worsen your situation. I myself have been bitten by xfs_repair and e2fsck (ext3 fs) in the past for example.

Book Review: FreeBSD Mastery: Storage Essentials

goarilla Re: UFS vs ZFS (75 comments)

I don't think so. ZFS protects all data blocks and data pointers with checksums. Not only the special filesystem structures (superblock, inodes, metadata tables, ...).

Book Review: FreeBSD Mastery: Storage Essentials

goarilla Re:What a crock (75 comments)

There is absolutely nothing on my laptop that I fear anyone else reading. Nothing. There are no passwords, no legally protected or privileged information, nada. It's an old, slow Dell that works fine for web browsing and simple games, too old to run anything processor- or memory-intensive like MSwindows.

What about saved/cached web service passwords/session cookies etc ...

Why Run Linux On Macs?

goarilla Re:Debian on shiny Retina Macbook Pro (592 comments)

I've got a nice reproducible case here--memory-intensive command-line utility dealing with image data, run it once it takes 1.5 minutes, run it a second time, it takes 2.5 minutes. No shared memory or semaphores or anything exotic, just malloc, use memory, free memory, exit.

I concurr that Yosemite isn't a very stable upgrade.
But are you sure your issue is related to virtual memory and not to the CPU clocking itself down because of heat.

Why Run Linux On Macs?

goarilla Re:Debian on shiny Retina Macbook Pro (592 comments)

What exactly is a "residual inactive memory allocation"??? Oh, that's right, there is no such thing--it's just a phrase you pulled out of your ass to shift blame for an OS bug which you do not understand onto apps. It's a UNIX variant, app quits, allocated memory is reclaimed.

Well Mac OS X doesn't kill applications when you press the "close" button, it only kills/detaches/hides/whatever the window
So I think what he thinks is residual inactive memory is probably used memory from any "closed" application.
That's kinda sad tough to keep rebooting to alleviate low memory issues because you can't figure out to properly exit a mac application.

Obama: Gov't Shouldn't Be Hampered By Encrypted Communications

goarilla Re:Hope and change (562 comments)

I mean shit, if you compare modern values to the Victorian era, we're all a bunch of uneducated rabble. All of us. For example, anybody who couldn't speak Latin fluently was an uneducated nobody (even though Latin was a long dead language by this era.)

You're talking about the age where education/science was a hobby for the highly privileged (aristocracy).
These people had servants, fortunes and real estate as support. And knowing latin isn't any different as knowing any other language.
Frankly, you have a very romantic view of the Victorian era.

Besides, there's been a somewhat long-standing theory that it's best to keep the vocabulary to a minimum. Using really complicated and/or obscure words doesn't benefit anybody, ever. At best, people who you need to get your message across to haven't heard the word before and misunderstand you (there are somewhere north of a million words in the English language; nobody anywhere knows all of them) and at worst you sound like a snooty asshole. It cannot benefit you in any way to constantly use them, but it can harm you and those around you. That's a fact.

I get what you are saying. KISS right.
The problem is sometimes you do have to use these "difficult" words since they describe more exactly what you want to mean.
And a bunch of clarifying sub-sentences doesn't make your communication more legible anyway.

Tips For Securing Your Secure Shell

goarilla Re:Well Then (148 comments)

I think he's only talking about the exploit mitigation technologies in OpenBSD (NX, ASLR, Stack protection, ...).
Not the overall level of OpenBSD's security which profits a lot from its secure programming processes.

Phoronix Lauds AMD's Open Source Radeon Driver Progress For 2014

goarilla Re:Great (44 comments)

I don't get it neither. Especially now when their graphics department is basically keeping them afloat.
It's prudent to have more resources dedicated to gpu driver development.

In that case the word "code" would have been more appropriate than the word library. This is slashdot after all.
