Is there any security or performance benefit from using a Chrome extension like EditThisCookie that deletes cookies older than a week in your browser?

security yes
performance no

I have a webm that's 4.9 mb and I have to compress it to 4 mb. How can I do this using ffmpeg?

Best way to store 1000000 phone numbers? Or sort them?

I just remembered Obama being asked about this almost a decade ago, and I never bothered to find the real answer.

Oh BTW:
He said "Not sure, but I do know a bubble sort is a bad idea" which was fucking awesome from a President.

I don't use those but I just don't keep cookies longer than a single session.

Reasons are simple, there are too many to track and I don't know exactly what they are doing. I haven't seen a cookie that enhanced my browsing experience except for the sites that I need to log in or keep some settings.

rencode with a lower bitrate
reencode to a different size dimension

Would compressing a file in multiple compression formats result in a hyper compressed file? For example, let's say I run bz2, then lzma, and then gzip. How compressed would it make the file?

But if you clear your cookies automatically every time you close the browser you have to sign in to every service you want when you open it again.
An extension like EditThisCookie let's you set the amount of time you want the cookies the stick around for to avoid this problem, you can just set it to one day or even hours.

You cannot compress compress data and expect a result

>But if you clear your cookies automatically every time you close the browser you have to sign in to every service you want when you open it again.
That's why I set exceptions for the sites I really want to keep. You don't need an extension for this in Chrome and Firefox.

I asked in the previous thread but I'd like to ask again: is it okay to have numbers in your mail address? I can't get my name and millions of combinations I've tried. So I'm thinking like first letters + some numbers.

uh how would you do that?

Thanks, that's actually a better solution.

ffmpeg -i file.file -b:v 500K output.file
ffmpeg -i file.file -vf scale=X:Y output.file

Merge them to do it at the same time so you dont waste more quality reencoding a 2nd time.

Is there an adapter that lets me use regular-ass M2 or MSATA SSD's in a 2013 Macbook Pro?

This 128gb stock drive isn't cutting it anymore and I don't feel the need to upgrade anything else, but holy fuck the proprietary Apple SSDs are stupid expensive

how would I know how much to lower them by?

Keep in mind that it's useless if you always open 100s of tabs and never close your browsing window. Other than that, I'm pretty happy with the results I get.

Why not?

Play with them to get your desired file size and quality.

If your source is 1080 try scaling it to 720(do this by setting scale to "-1:720") that should shave some mb off of it, it not try changing from 500k to 400k 300k etc till it works for your source

explain like im a redditor.
how exactly do i use autodll-irssi to download files my seedbox.

You cannot compress compressed bits,
There is no data to compress after a compression

How can I access my BIOS? I've tried pressing f2 which is the correct key, also tried with f10 but still nothing.

f2
f5
f10
f12
del

it's 720p right now and it's a music webm with a still image anyway so I'll just lower the resolution some more
thanks

I prefer to keep a separate music player on me. I just lost my old ipod touch and someone probably has seen all my shit taste

tl;dr Portable music player device recommendations?

it says press f2 for setup and it doesn't work

So its just a still image?
Set the bit rate to like 10K and see how it looks.
How important is the image? Cause you could scale it down to 480 or even 320

Please, I need validation.

What's a compressed bit? A bit is a bit, no?

For webpages that display no files in their URL e.g. Sup Forums.org/g/, how do they work or run?

For example, www.example.com/index.html is a HTML page and you know this because it has the /index.html in its URL. Same goes for www.example.com/home.php - you know it's a PHP website because it has /home.php in its URL. So if a webpage doesn't have a file in its URL, how does it work or what is it?

I scaled it down to 480 and it increased it to 5.2mb. wtf

The server program has a list of files that are acceptable for index pages.

ffmpeg -i file.file -vf scale=-1:480 output.file
Like this?

ah maybe I did it wrong. I tried to do 480:480 to scale it to a square and remove the black bars around the image but I guess that's not how you would do that

Don't scale, the bits saved per drop in quality is worse than just setting a lower bitrate. Also if you are targeting a specific file size, you want to use 2 passes.

The Sup Forums wiki has a good page on encoding webms for Sup Forums with ffmpeg.

/pcbg/ is dead, so ill ask here.

best x399 mobo? looking at aorus/gigabyte since their x370 mobo is working well for me. msi is the other main option im looking into .

>Sup Forums wiki
Its been down for about a week

What can I do lads?

In theory it could, because compression algorithms aren't perfect and might leave some redundancy. In practice I doubt it will save you more than a few bits if it works at all.

Compression works by removing redundancy and predicting common patterns. Compressed data usually has no redundancy or common patterns left to remove. It should appear to be completely random data.

Any bored people want to help me with this?

Is there a way to machine learn when nipples are being show on a video, and if they are output the time stamp at which nipples start and stop being show in a video? It would happen multiple times per file

Working with bitwise operations in java and I'm sort of confused on what to do.

let's say we have the example byte "01101001".

I want to separate this into "011", "010", and "01".

How would I do this with masking and shifting? If I use left shift, it adds more zeros to be evaluated, causing the number to be way too big.

alright so the webm is 280 seconds long so I would do (4/280)*8 = 0.114285714286 right?
so then what would I enter for the command?

How do i do two pass in a single script?(bash)

I need it locally.I have 100gb+ files that i need to sort out from extended video chat sessions

what do I do with this? enter the amount of mb for x?

Where the fuck can I buy a NA oneplus 3t that isn't more expensive the 5?
Holy shit

Maybe k instead of M
-b:v [x]k yeah

-b:v 4k lowered it all the way to 2.3mb instead of 4mb
what's going on

best gaming hdd for

No (4MB/280s)*8MB/Mb = 7.314 Mb/s. Round down because your video might be slightly longer than exactly 280s and there is some overhead with encoding and it isn't perfect. So your bitrate option will be -b:v 7.2M and if that doesn't work try a bit lower.

Also annoying here is that different software and people use different meanings of "Mega" to mean 1 million bits/bytes or 1.024 million bits/bytes.

ffmpeg -i input.mp4 -b:v 7M -pass 1 pass1.webm
ffmpeg -i input.mp4 -b:v 7M -pass 2 pass2.webm


Note that using multiple passes will create extra files in that folder where ffmpeg stores metadata, and you should delete those when you are done. If you really need this to be one line, you can combine it with &&.

I think this is all correct, test it and tell me if it works because I always screw stuff up when formatting commands.

So this(ill add the variables later)
It will do each command one at a time?
#!/bin/bash
ffmpeg -i input.mp4 -b:v 7M -pass 1 pass1.webm
ffmpeg -i input.mp4 -b:v 7M -pass 2 pass2.webm

why dont you let your cat sleep in front of your monitor?

I believe that will work. I think you might need line endings (;) at the end of each line, my bash is very rusty.

then do M

Oops I did my math wrong (thanks wolframalpha for automatic unit conversions.) It should be 114K.

what do u guys think? i dont think i need any apps besides netflix for win10.. should i use ltsb? or downgrade to 8.1? i dont mind security updates but i dont need creators update shit etc coming out. i dont need extra stuff. what do. or continue using win10 pro and powershell remove bloat? ffs why does MS make this so hard. should be minimal from start

Should i make a I5-7600K build or wait for the I5-8600k?

When will coffe lake be released?

I don't really know much about the market for these, but what is a good standalone RAID box? I don't have a computer to buy a RAID card for, so I figured why not look around for some standalone devices.

Is there anything that comes close to DBAN that is designed for SSDs? I just want to format because the last W10 update corrupted my SSD

Cell reset

TRIM.

>Is there anything that comes close to DBAN that is designed for SSDs?
Just drill it.

SSDs are much easier to destroy than HDDs,

DBAN is not a formatting tool.

I'm trying to install Arch for the first time after installing Ubuntu successfully many times and I just keep getting an error. Is there anyway to copy the error message I'm getting somehow? (saying something about only 10/11 ae tables loaded correctly)

>Move NAND chip to another SSD
>Copy data
>Easier

Do you know what drilling it means?

>10/11 ae tables loaded correctly
I've never heard of this.

What were you doing when you were installing arch?
Are you following the wiki?

Could anyone help out a dumb user trying to learn how to code?
Here's where I tried looking for an answer
github.com/Microsoft/BashOnWindows/issues/1598
If it helps, I tried running an already compiled file from cpp. I wanna git gud at this, anons. And if you guys think atom isn't all good could you insist a better text editor that I could compile and run most languages?

>Move NAND chip to another SSD
That's hardly easier.

Probably wouldn't even work because the controller would have no clue as to the state of the chip.

Audiophiles have ruined audio files.

I just want to encode audio at shit tier bitrates (8kb/s and below.) Obviously this isn't great for music, but it's acceptable for speech content like podcasts, especially with modern audio codecs. I just want to fit dozens of hours of content on a cheap mp3 player.

The thing is ffmpeg and the encoders it uses only go to about 16 kb/s for aac. Any way to make it go lower, or are there other encoders that can do this?

what widget library does xfontsel use?

Are Zenpads good tablets? How much freedom of modification can I expect from one? I want a tablet primarily to read comics and manga and web browsing.

>installed Atom
Well, I'll sum it up quick.
There's your problem.

Exactly, I'm not sure which part really is the "error", which is why I want to copy it. (Its a long block of text)

However, you just reminded me I can just install from an existing Linux machine, which I'm going to try now. ty

Well then what is a good text editor for windows that comes with or has downloadable plug-ins to compile and run code? Like I said, I wanna get good at this so... yeah.

Many of my colleagues seem to think that database enforced typing, and short-ish string field lengths constitutes server side validation because
>Hey, we say you need to have javascript enabled, and int/date/etc... just can't be put into the DB if they try to bypass the client validation
Nevermind that in many cases if this happens the side will just throw a 500 error instead of handling it.

I'm not being the retarded one in saying that's ultra-stupid, right?

I never use the cameras on my smartphone so i currently cover them with electrical tape just to be safe, the tape looks a bit dodgy and every now and then when i need to use the camera the electrical tape leaves some residue and these stickers claim that they don't.

just use some tape, goyim
