i get what denpa meant on this post
i dont feel like replying anymore either
posts like P92588 are to wrong on so many levels that would be a lot of typing to correct every mistake on denpatard's line of thinking
and it would all be pointless in the end, it has already long been established that denpa is incapable of learning
the simple fact that he comes here to share his opinions in hope of getting validation is self-evident proof that everything he is spouting is categorically incorrect, but he is unable to see it himself and explicitly pointing it out wont do any good
so why even bother

I hate stupid fighting scenes like this.
With a long weapon, you don't block a dagger like that, you use the length of the weapon to keep your opponent out. Your advantage is your much greater range. If you let them get that close, you're fucked.
With a dagger, you don't do a downwards cut like you're chopping with a katana. You stab. Daggers are thrusting weapons, until you have gotten in, then you start twisting them around and letting the edge further lacerate your opponent.
This scene just doesn't ever happen.

Also, women just pull eachother's hair when they fight. So yeah, not real at all.

After tisming a bit at a coffee shop, I might as well start blogging.

I had gotten my food and coffee and was stepping out, but had my hands full. The door was a push door, with a horizontal bar at about hip to waist height for most people. I opened it by lifting my knee to just above it, and pushing it open with the top part of my shin. The door had a dashpot, so it began closing again, so I caught the push bar with the elbow of my arm that was on the same side as the door.

I only realized after getting outside that I probably made a spectacle, and at least 4 people were sitting so that the door was in their field of vision, not counting the employees.

Why do people buy coffee? It's so simple, and the stuff you buy isn't even that great.

People get cancer in their 60s because of things they did in their 20s. Only a complete idiot (i.e., you) would think that a time gap disproves causality.

Furthermore, as much as I would like to frame Protestantism as a disease that spreads completely in one go, it isn't. The English became Protestant, and there was continued correspondence between German and English Protestants over the centuries, whereby awful ideas from one side would cross to the other.

The term borderline was coined in the year 1938.
This means that borderlines never existed before 1938 which is true because I didn't exist yet.

You're stupid. I didn't claim pedophiles didn't exist before this time. My evidence shows that people did not have a specific word for them, because they didn't need one; they hadn't othered them yet.

In the last couple of days Tor network started to slow down on my end, is it just me or is something going on?
A week ago I could download vids at 3MB/s tops, 500kb/s lows and 1MB/s average, now I can barely go beyond 100kb/s.
That or Google started throttling speeds on Tor nodes to fuck us over, the anon invidious users :'((((

Something's likely up. Yesterday a 300mb file took forever to download. I2p was (is?) under attack so maybe that has something to do with it. Google can die in a fire though.

And then you wonder why there's no low-incoming or affordable housing available. Few people would want to rent out under those circumstances.

P92230
From the times I had to pay one, I always did. I'm not a slob and know how to fix things. Matter of fact, if I have to call the landlord to fix something it's an insult to me as a man, because a man should know how to fix things and not need anyone else.

In case you don't trust your landlord to give the deposit back, you can just not pay your last month or so of rent. They could sue you for it, but then they would have to justify keeping the deposit on top of wasting time and money in tribunals.

we are in an economic recession, you dildo fucking faggot. dont confuse that with your pet narrative.
here is the corporate faggot invalid argument to go along with your communist faggot invalid argument:

i dont know man, I cook tons of oil, most likely id get the pipes clogged before im out

We have 2 options:
-elegant aristocratic boobs
-mommy milkers

each option has its advantages and disatvantages, so let me list some:
smol bobs:
+smaller profile=can wear body armour and maneuvre weapons much more easily
+less eye catching=people wouldn't want to instantly sex her
-cannot produce milk to satisfy a man's thirst
-the women usually are either very frail (or strong enough and very agile if they're in the very few, small minority of smol bobed woman)
big bobs:
+massive boobs=lots and lots of naturally produced milk, perfect as a daily natural suppliment for growing muscle as big as her boobs
+can hide different objects in her boob purse, rendering the need of carrying around purses and bags obsolete
-greater profile=attracts other men and is harder to protect via body armour
-sluggish due to their massive bobs, their bobs eventually falling when they get older and will look ugly, unless properly maintained (very very very few)

P92676
best choice is getting fit, finding a fat virgin that will look 1000/10 once the fat is removed and boom, ggez
the 2nd part of this solution requires knowledge, such knowledge can be acquired via watching americuck TV shows where obese, ugly w*men become slim and sexy, or at least some become slim and sexy, the rest just become slim
you gotta figure out who becomes slim and sexy from fat and ugly and not only you'd get an ultra loyal bitch, but a sexy ultra loyal bitch, as long as you choose them right ("personality" in w*men matters quite a bit)

There's several parts to this.

1. When I used to use random names, I wanted something that would get attention and stand out. People use various symbols so I put ☣ in the name field. It's a symbol you can type. Sometimes I used the nuke symbol, or a cat's face.

2. I started digitalsr because I was blocked/banned from pretty much anywhere. This being the case, I must be toxic, correct? When I learned Inkscape I worked the symbol into the site logo (pic rel). Some, but not all, of my images have that watermark [spoiler:probably only 5%]. The bottom font is ID4 Alien Script and says "End Of The Line". Skid row is a nod to https://en.wikipedia.org/wiki/Skid_Row,_Los_Angeles . Since it's online, it's "digital".

3. Toxic as in "sarcastic, snarky, shit posting, or offensive", which is often my sytle.

It has nothing to do with AIDS, HIV, or leftism. Link #2 is probably the closest.

yeah ok brandall

I have a couple books I scanned some time ago but never got around to properly clean Are there any tool that would do this mostly automatically? In particular, I would want the tool to:
1. Detect the text direction and unskew the page
2. Separate images and text
3. Convert the text to grayscale and apply thresholds
4. Fix the white balance on the images
5. Run OCR on the text
6. Combine all the layers into one pdf
Attached are the results I would like after steps 1-4. I don't know how or if the cropping could be done automatically, but that isn't a big issue.

Is there any (free) tool that can do all that? I can do 3 and 4 with imagemagick, 5 with tesseract-ocr and 6 with pdf-tools, but I can't find anything for 1 and 2. I don't really want to pull out opencv if someone has already done the job.

Support for JBIG2 was added in PDF 1.4 (2001), so I guess since then.

Holy proprietary

Anyways, I was sort of mistaken in P92403. I didn't check carefully, but the output from pdf2djvu is terribly lossy, and the conversion to pdf just converts the djvu to jpeg and embed that into the pdf, so it's lossy again. Changing the options of pdf2djvu to have a better quality makes the document substantially bigger.
I managed to get better quality by hand-building djvu files, with a 600dpi text layer and 200dpi background layer, the quality is quite good and pages that are mostly text with a couple pictures compress to less than 100kB/page. Unfortunately, it takes some time to properly clean the backgrounds.
I've found the tools used by the internet archive to generate their PDFs. I'll see if I manage to use them to do what I want.

Yeah, DJVU requires a lot of tuning.
