A: On a dual CPU server, is it normal for one CPU to run hotter than the other?

The problem ended up being a poorly fit heatsink. Maybe poorly fit isn't the right description. Turns out, you have to put thermal paste on the heatsink, not the plastic cover that goes over the heatsink. After removing the plastic cover, the CPU is nice and cool, thanks everyone!

If you want to get further down the rabbithole of forensics, I can suggest a few books

Forensics wiki is useful, but kinda lacks depth

A: What shredding utility can I use?

With conventional hard drives, a single wipe with zeros may be enough The 'multiple wipes' method assumes that you're using older drives (with larger magnetic domains). The 'definitive' paper on data destruction by guttmann suggests 35 different patterns - which are effective on different types ...

Also, you never ever work with partitions at acquisition stage in forensics.

Q: Why are write blockers needed when there is mount with read-only?

Let’s say we're using some flavor of Linux and we mount a partition using following command: sudo mount -o ro /dev/sdc1 /mnt The partition is supposed to be read-only so that the OS and user cannot write to the disk without changing the mount permissions. From the ForensicsWiki: Write blo...

"Turns out, you have to put thermal paste on the heatsink, not the plastic cover that goes over the heatsink"

See now if they would have rubbed the goop into the heatsink first, so it gets into all the pores, and reduced the chances of any air existing, that would be far less likely to have happened.

@Psycogeek The picture made that question - I think without it that post would have been downvoted into oblivion =p

Question
As you know, `curl url > /dev/null` will redirect curl's result to `/dev/null` effectively suppressing its output. Some progress data is still presented in the terminal however. I know I can avoid this by using `curl -s url` or redirecting the `stderr` to null along with `stdout` like 2>&1. But the question is, why is curl's progress status redirected to `stderr`? (which is what I deduce based from these observations).

Journeyman Geek

@HackToHell: Looks more like an issue with linux crashing.

So... try a known good image before panicing ;p

HackToHell

@JourneymanGeek Yeah, I kinda uhm forced a image

Journeyman Geek

@HackToHell: is this on internal or external storage?

HackToHell

Fortunately Intel has some kinda preloader

It's easy to fix

But for some reason I can't forward key board events using cu in ubuntu

So I can't get it to firmware recovery mode

So I'm trying from windows now

Journeyman Geek

cu?

@JorgeBucaran: ._. Unless you designed curl.... you wouldn't know why ;p

Jorge Bucaran

So curl does send the progress meter to stderr.

The myriad chips Intel makes are actually divisible into several broad groups

Y is ultra low power for tablets and Ultrabooks

Journeyman Geek

._,

with reference to... ?

DragonLord

U is low power (not as low as Y), for more powerful Ultrabooks

H is for socketed and soldered medium-power mobile chips

This one is more confusing—the Haswell-MB parts (socketed mobile, high-end laptop) and Haswell-H parts (soldered desktop, SFF and AIO systems) are actually from the same underlying H die

K is performance desktop, often unlocked for overclocking

Journeyman Geek

K is always unlocked and overclockable

DragonLord

Note that some desktop chips, like the i5-4570, are based on the K die despite having a locked multiplier

Journeyman Geek

If you have a non-k chip with a k equivilent, the difference is usually vt-d (on the locked one) and unlocked clock (on the K varient)

DragonLord

6:32 AM

S is mainstream desktop—these are your desktop Celeron and Pentium chips (not to be confused with chips like the i7-4770S, which is built on the K die)

...as in Skylake-S

Journeyman Geek

Also, IIRC some celeron and possibly pentium chips arn't 'mainstream' they're atom based cores.

DragonLord

@JourneymanGeek I'm referring to the desktop chips

Journeyman Geek

So am I

pcworld.com/article/2040401/…

DragonLord

Well, that's unexpected

...but the Haswell-based Celeron and Pentium (and some Core i3) processors use the S die

People call the G3258 "Pentium-K" but this is really an unlocked S chip

Journeyman Geek

yup

That's why I said 'some'

I have a semi-desktopish celeron bay trail in my brix

there's also supposed to be 4 and 8 core atom mini itx boards floating around

DragonLord

6:40 AM

@JourneymanGeek I suppose these are engineering samples

Continuing from before:

E is enthusiast desktop—Intel calls this HEDT

These are basically scaled-back server Xeon chips

Journeyman Geek

IIRC they're essentially xeon e3 ~~boards~~ chips

DragonLord

EN is entry-level server—these are the cheap Xeon processors

EP is performance server

EX is high-end server—these chips run nearly $10,000 a pop

In regards to the matter of size, I thinks it's commonly acknowledged that it's not really the length that is most central to performance, but the girth. Longer tools to tend to have a larger girth as well, and length is a vivid and easily visualized quality, but it's really issue of correlation vs causality here. Either way, most of them do their job fine regardless of the variances in length or girth, and success it's mostly a matter of technique and adaptation to what you are screwing. — Alex 24 hours ago
