6:56 AM

@Burgi I was in an car tyre fitment garage yesterday, and was quite bemused by a worker walking past with an AirPod in one ear. It seemed neat.

A: What are the best options to use when compressing files using 7 Zip?

After much experimentation, digging into the detailed 7zip documentation, and reading some of the 7z source code regarding the advanced LZMA2 parameters, here is a better method below. It reduced some 1GB real-world test files more than 2 to 4 times better than the previously accepted solutions p...

have you tried these params?

I can't get them to work, says "parameter is incorrect" but not which one and there's a lot

using windows 10 and command line

using the default GUI the best result I could get is regular LZMA2 on ultra, doesn't really improve appreciably for the files I'm compressing if the dictionary or word size in increased even to the max

I was interested in how much this could be pushed so I looked it up and here's this recent answer but idk what OS the poster uses or what builds of 7z they're talking about

it's not working for me tho

bounties gonna bount

9:35 AM

ping me if anything comes up about this, otherwise I'll read the comments or answers on the post from my inbox

some orchestral pieces can get faster if the orchestra is used to playing the piece and are familiar with each other

Well, that was fast.

@bwDraco What do you think of the OneUI or whatever it is Sammy are calling their Android 'experience' these days?

A friend is swithering between an OP7P and some variant of Samsung - A70/10e/10

OxygenOS is pure and simple and wonderful

but Samsung's stuff you can tweak a fair bit?

It's actually decent. There are some things that Samsung likes to push but you do generally have the option to disable them.

And some features Samsung adds, like the edge UI and clipboard manager, are genuinely useful.

Only now am I actually appreciating having a clipboard manager, considering Windows 10 now has one, too.

brb as I apply the update.

...and that didn't take long.

2:19 PM

What does the measurement signify in 2.5'' or 3.5'' hdd?

Physical size of the drive

Historical disk sizes. Remember 3.5" or 5.25" floppies?

What is now used for the optical drive is called the 5.25" bay. There are no longer hard drives of this size, but the name stuck.

I mean the size of spinning platters or the whole case?

The standard hard drive size for desktops is the based on the standard size of the 3.5" floppy drive.

@Biswapriyo The size of floppy disks that were used in drives that fit into that bay.

djsmiley2k - CoW

@Biswapriyo whole case

physical width of the device is 2.5inches, or 3.5 inches, respectively.

2:22 PM

something something a thousand words

Well, that is interesting.

though the Seagate there is, uh, a lil ~~over~~ under 4 inches

I stand by my word. It's a matter of the historical sizes of the drives used for floppy disks of the named size.

A drive bay is a standard-sized area for adding hardware to a computer. Most drive bays are fixed to the inside of a case, but some can be removed. Over the years since the introduction of the IBM PC, it and its compatibles have had many form factors of drive bays. Four form factors are in common use today, the 5.25″, 3.5″, 2.5″ or 1.8″ drive bays. These names do not refer to the width of the bay itself, but rather to the width of the disks used by the drives mounted in these bays. == Form factors == === 8.0″ === 8.0″ drive bays were found in early IBM computers, CP/M computers, and the...

the WD is a lil over 2.5"

@bertieb ""A picture is worth a thousand words"

2:25 PM

@djsmiley2k-CoW Not true. It's called a 3.5" drive because it's the same size as a floppy drive that accepted 3.5" disks.

@Biswapriyo something something close enough

Same holds for the 5.25" bay (used for optical drives) and the 2.5" bay (used for laptop hard drives and SSDs).

djsmiley2k - CoW

TIL.

So to answer @Biswapriyo - Neither.

wow, we say something something a lot.

@djsmiley2k-CoW It's mainly @bertieb :p

i think CDs are roughly about 5" across

atleast the full sized ones...

2:31 PM

In fact, the standard 5.25" floppy drive was twice as tall as a modern optical drive. The standard optical drive bay size is actually considered to be half-height.

(and yes, I've worked with 5.25" floppies a couple of times in elementary school)

djsmiley2k - CoW

interestingly a cream cracker is exactly 2.5inch across too.

Introducing Subject Matter Experts

Lori Colston on December 04, 2019

One of the great secondary benefits of an open knowledge base like Stack Overflow for Teams is that anyone can contribute. When exceptional answers get voted to the top, your organization gets to identify subject matter experts. Today we’re excited to announce our new subject matter expert feature that allows domain experts to be easily recognized and acknowledged within your organization.

The new feature, available on the Business tier of Stack Overflow for Teams and coming to the Enterprise tier in 2020, allows your Team to associate a subject matter expert (SME) with a tag. Multiple Team members can be designated as SMEs for any given tag by your Team Admin. …

3:31 PM

this is a bad idea

For Teams?

Can see it working

If any of yopu hear a louyd explosion in the next few minutes, that will be y desttop

I have not made backup in 1.5 years and I am about to start

Last time LI let if laptse that long the RIAD card broke when I arrived home with new disks to backup to (still wrapped in their packaging)

Re drive bays. I miss the 8 inch mini diskdrives

looks at room topic

Good luck, godspeed

6:31 PM

Oh, I do have backups. And I am about to overwrite them (rather than my usual 2 disk swap, one with previous backup, one to write to)

And windows is not playing along. USB to esata device inserted. Esata to external disk..... nothing detected.

TIme for a reboot

7:07 PM

So glad Kate over in R&D pushed for using the AlgoMaxAnalyzer to look into this. Hiring her was a great decisio- waaaait.

7:18 PM

Finally. Disk found

Windows and USB continues to be something which works very poorly

PLug in 8 times. 8th time it might work.

But... backup folder 2018 05 09 found

So a year and a half was about right

1 hour later…

8:29 PM

Here we go again. Backup stopped. Device nog recognised after writing 1TB of data to it

Right, rebooting again

Post reboot. Wait 2 min for USB to atapi bridge detection.got to diskmgmtn.msc. Rescana. Found the single 10TB partition. It is 2TB.

Windows, let me count the ways I love your reliability.

reboot. Ah, now the USB device is not recognised.

Ah, device disappeared during a disk rescan.

djsmiley2k - CoW

8:55 PM

ew usb tho

9:15 PM

Aye.

I tended to just use the eSATA port on the laptop,
or the eSATA port on a desktop

But the modern systems lack this nice and useful port

So either I buy an add in card, ir a Itry USB to eSATA

Or use the old USB-2 port on the dock to backup 5TB at 30MB/sec....

I guess I could buy a QNAP or other NAS and just connect via Ethernet (SPF+)

Or I could have more free time and actually finish my home build NAS (aka desktops with 10GBit + lots of room to toy with

Last is more fun, and will eb started 2 years ago... so sort of goverment compatible IT project here

Not quite my day.
Moving on from backups before I get frustrated.

Get work laptop, insert deadless 4k HDMI dongle.. Max 2k on work laptop (lenovoa thinkpad 490).
Same dongle in my own laptop nicely does 4k (4096x2160 even)

9:36 PM

... and the saga contrinues.
Plug in monito directly (via a too sshort USB-c cable. work perfectly.
Get the new longer USB-c cable... No image

I need to step away from the computer and grab some beer

10:11 PM

$("#buttonSubmit").prop('disabled', true);

Oof.... that's a bit savage.

TechnicTechnician

what would it be called where a game has a 3D space such as a cave and a wall can appear solid but when you move into it it is not and is actually another small tunnel

is it like 3.5D or just 3D with optical illusions

it is randomly generated too though, what is and isnt solid

Example?

TechnicTechnician

its in lego worlds

at least it was in the beta version

Just sounds like 3d but with weird / shifting / nonstandard topology

like antichamber

something something "multistable perception"

TechnicTechnician

I just tried to find a video of the game but its full of KIDS vlogging

I hate kids on youtube >:(

whatever its called, where you talk rubbish while gaming with a webcam

10:27 PM

cough

wouldn't know anything about that

TechnicTechnician

i'm not up to speed with that terminology

<.< >.>

TechnicTechnician

same, all I had was win95 and midtown madness2

and playstation 1

That's 25 years old... yesterday?

TechnicTechnician

youtube.com/watch?v=fJEwY6xwbzU I guess this but they were more colorful when I played it

thered be a small hole for a tunnel but it would be camouflaged because of the bricks

10:29 PM

time?

TechnicTechnician

but it felt like 4D and It was amazing, until the game got pulled out of BETA and sucks now

2:30 onwards thought he might not go through one, you can see how it might be camoflauged

just looks like a portal

TechnicTechnician

I dont mean him using the tool to dig of course

Aye

I think I know what you mean

falls through something and world reorients

Like a fake wall?

10:36 PM

threatpost.com/smbs-nation-state-actors-apts-targeting/150836

TechnicTechnician

its just a hole but the shapes and colors and lighting make it appear like its not there

I cant believe how shoddy the release version is, I have tried playing it 3 times and it always glitches in the 'select world' screen literally 20 mins into the game, so you cant go any further

heres one youtu.be/5JQIf-YP57w?t=753

Ahhh, okay. So it's just hidden by misdirection. You're looking at something else, and because of the shadows you don't see what is right there.

TechnicTechnician

yeah.

I probably wont be able to get a refund either because the glitch happened years ago and still existed when I played it again last month. it had one tiny level then it glitches when you complete that level
