@HornOKPlease I saw them, but... the raw $$$... :(

12:55 AM

@Bob yeah, not to mention I just renewed my Ivy Bridge SP-128

I would even be hesitant to buy an OVH server in the US (still not generally available, how many years now?) because my one-time purchased IPv4 subnets (two of them!) are in their ca.ovh.com manager :P

and I'm not running anything CPU-intensive right now anyway. Mostly stuff that takes a few hundred megs of RAM and is idle 99.9% of the time :P

...welp. Slipped and fell (or should I say, slid) down a flight of stairs. I'm not seriously injured or anything, but briefly felt briefly dizzy, probably due to the repeated impacts.

(had socks on, slid on hardwood)

rahuldottech

@bwDraco take care

@HornOKPlease I want an ipv4 subnet of my own!

Journeyman Geek

@rahuldottech here kid, have a RFC 1918 subnet ;p

rahuldottech

> Private network

...

Journeyman Geek

Its a subnet of your own

and it can get pretty big

Michael Frank

possibly hundreds of IPs!

Journeyman Geek

7:21 AM

thousands!

rahuldottech

@JourneymanGeek isn't this what every router does?

Journeyman Geek

@rahuldottech depends on your IP scope...

the usual 192.168.x.x range only has 254 IPs

rahuldottech

@JourneymanGeek ah

Journeyman Geek

I only really have 100 or so IPs dynamically handed out

I could probably go with 20-30

bwDraco

Rather nasty abrasion wounds on my right arm. Nothing serious like broken bones or anything like that, though.

Journeyman Geek

7:30 AM

@rahuldottech what I'd love is more options for Ipv6

there's maybe 2 local ISPs

bwDraco

It's been bandaged. I'm fine for the most part and should not have much trouble with everyday activities.

Journeyman Geek

or I'd need to set up a tunnel. It wouldn't be a total horror - that's the nice thing with running your own hardware and most modern routers have that as an option

bwDraco

Didn't suffer anything like a head impact, FWIW.

Nor have I sprained any joints.

I'll get some rest. See y'all tomorrow.

Horn OK Please

@bwDraco Take care of yourself!

rahuldottech

@JourneymanGeek can't wait to get out of school so I have the time to mess around and experiment with stuff like this

bwDraco

7:44 AM

Thanks, folks.

I'm not wearing socks again when going up or down stairs. It's just not worth it.

Journeyman Geek

@rahuldottech quite honestly I spent too much time doing stupid shit in school

I ran all the OSes I could get my paws on

for example en.wikipedia.org/wiki/Syllable_Desktop

ROS...

I can't even remember half of em

bwDraco

I didn't do any of this but I actually fired up Haiku R1/Beta 1 in VirtualBox a bit earlier...

Anyhoo, time to go to sleep.

bwDraco

8:01 AM

(also had brief stints with stuff like Plan 9, which is now discontinued, and ReactOS, but most of my VM time was spent on Linux)

And for a very brief period, MINIX 3.

And a bit of FreeBSD and FreeDOS.

So I did actually play with a bunch of exotic operating systems, though not quite to the same extent as @JourneymanGeek did.

rahuldottech

11:02 AM

@JourneymanGeek yeah, I did too. But now I really gotta focus on grades for a couple months

CowperKettle

4:47 PM

I cloned my systep on an SSD, booted from the SSD, but when I start programs I can clearly hear my HDD creaking. I've made sure that my system indeed runs from the SSD. I wonder why the HDD makes noises at all

bwDraco

@djsmiley2k Ow.

I had mostly slid down the stairs, repeatedly hitting my butt, but there doesn't seem to be much more than bruising and pain.

I think the arm abrasion injury is the hard part.

Neither hand was free at the time; I was carrying things out of my room and downstairs to the kitchen.

I'm going to run HDDScan

And see if there are any bad blocks on the surface

DavidPostill

Marvell controller but variable BOM (the NAND and possibly the controller itself will vary from unit to unit)

DRAMless. Random I/O performance will not be great.

Ow.

When close to full, random writes can cause the drive to periodically drop to zero IOPS.

Huh. New release adds support for the JMicron JMS583 NVMe to USB 3.1 Gen 2 bridge. That's great news for those with a MyDigitalSSD M2X.

Interesting. Armv8 support?

Wait a sec. They now have Armv8 Win32 binaries!

8:31 PM

W32, does that still exist?

Horn OK Please

@Hennes of course it does

Hennes

I guess. Flash also still exists (the adobe version)

Horn OK Please

Win32 is the highest momentum API/ABI ever created

2

every x86 (32 or 64-bit) version of Windows since Win95 has supported it, and apps written for the original 32-bit release of Windows 95 still run "mostly fine" on modern Windows with few exceptions

there's more code that runs on the Win32 platform than any other ever conceived

probably even the web, if you count JS but not HTML

more new code is definitely being written to be cross-platform (Java, .NET Core, JavaScript) today than code targeting Win32 directly, but the amount of legacy code out there is truly staggering... everything from industrial control systems to airport terminals to aircraft carriers to >90% of games run on Win32

and Win64 is a close relative with a nearly identical API surface but just using 64-bit memory addresses, and most new native apps at least support that as one of several targets

That Brazilian Guy

Hm...

The cheapest I can find here is a 120G Kingston SA400S37 for USD 28 (no shipping, local store).

Maybe I should invest on it, I've never used a SSD-powered system before and I heard the difference is night and day.

32 pages of SSD options. FFS.

240G Hyundai C2S3T for USD 44

Hmmmmmmmmmmm

Canadian Luke

@ThatBrazilianGuy There are different technologies inside that make SSDs either the best, or the worst, for your computer. Do some research, or else go with a decent company like Intel or Kingston or Crucial

That Brazilian Guy

I can't pay for decent stuff =/

Canadian Luke

Back in the day (read: over 5 years ago when it was new), I paid $100 for 128GB SSD from Kingston. Prices have come down quite a bit

That Brazilian Guy

9:54 PM

I know there is Trim support to take in consideration. And number of read / writes / hours. Other than that, not much.

bwDraco

> number of read / writes / hours

It's really just a matter of TBW and warranty length (typically 3-5 years).

That Brazilian Guy

TBW?

bwDraco

TBW is the endurance rating of the drive: the number of terabytes you can write over the life of the drive under warranty. Most drives will last well beyond that number but it isn't warranted past this point.

That's because each flash memory unit can only take a finite number of writes.

10

A: Why do SSD sectors have limited write endurance?

Nearly all consumer SSDs use a memory technology called NAND flash memory. The write endurance limit is due to the way flash memory works. Put simply, flash memory operates by storing electrons inside an insulating barrier. Reading a flash memory cell involves checking its charge level, so to re...

That Brazilian Guy

When I finally buy a SSD, I plan to write stuff like / and /boot to it, and write /home to a HDD.

bwDraco

That's one thing I like about Linux. Storing different things in different volumes is a cinch.

Windows does have mount points but AFAICT they're not designed to allow moving entire user profiles to another drive. You can move certain key folders like Documents, Downloads, and Pictures to another drive using a feature called Known Folder Redirection.

That Brazilian Guy

9:59 PM

@CanadianLuke Other than Trim support and TWB, what other aspects should I keep an eye open for?

bwDraco

The underlying technology of the drive. DRAMless drives are the cheapest kind; as their name suggests, they have no built-in DRAM buffer for storing mapping tables, which can result in poor performance during random writes, especially when the drive is nearly full.

That Brazilian Guy

...dammit, my headphones are damaged.

bwDraco

Value-oriented drives are likely to be DRAMless. Better drives will have a DRAM buffer.

That Brazilian Guy

Anything might be better than a 5yo laptop HDD

bwDraco

Then there's the type of NAND. There's SLC, MLC, TLC, and QLC (from better to worse in terms of endurance and performance). (SLC is no longer commercially available, and MLC is very expensive.) Planar NAND is simply a flat layer of memory cells, 3D NAND uses newer manufacturing technology to stack many layers of memory cells, one on top of another, allowing higher performance, endurance, and density.

Most drives use TLC NAND. Although 3D TLC NAND is the type typically found in modern mainstream and many premium SSDs, cheaper drives may use planar TLC NAND.

(there are a few 3D MLC NAND SSDs made by Samsung; these drives are branded PRO and are generally very expensive)

A: How can data be lost on an SSD drive?

Most SSDs use NAND, which retains data without power. Most SSDs use electronic chips called NAND flash memory. NAND itself is non-volatile, meaning it retains its data even when power is removed, but data loss can occur in a number of different ways that are very different from how an electromec...

> As for long-term data retention and data loss over time, flash memory operates by storing and sensing electron charges in an array of floating-gate MOSFETs. This electron charge can be changed by essentially forcing electrical charges through the insulator that forms the floating gate in each transistor to store data.

Over time, electrons can leak out of the floating gate insulators, resulting in data loss or corruption. This process may take many years for flash memory that has not seen much use, but an SSD that has seen heavy use will have worn down the floating gate insulation inside …

As for TRIM... Most modern SSDs support TRIM, a command which tells the drive which blocks are no longer in use and can be erased.

That Brazilian Guy

10:10 PM

However I only have this laptop with a single SATA slot. So I'd have to buy a SATA caddy adapter. And give up on ever reading CDs and DVDs again.

bwDraco

Ow.

That Brazilian Guy

Thanks for the tips @bwDraco, I'll be sure to take a look into it.

Ha! A SATA caddy is almost ridiculously cheap (10 USD).

A: Over-provisioning an SSD - does it still hold?

Modern SSD controllers are smart enough that overprovisioning is not typically necessary for everyday use. However, there are still situations, primarily in datacenter environments, where overprovisioning is recommended. To understand why overprovisioning can be useful, it is necessary to underst...

Understanding write amplification, why TRIM is useful, and when overprovisioning can help increase performance and endurance.
