Why cloudflare is agressively blocking jdownloader now (with fix)

So its more of a jdownloader issue and not a cloudflare issue, though ultimately cloudflare is the one blocking. Let me explain.

Recently cloudflare has been checking useragent w/ types of tls fingerprint. If you get a missmatch between useragent, tls fingerprint the useragent should support then you get a cloudflare block **even if your IP has good reputation**.

JD2's default UA is "Mozilla/5.0 (X11; Linux x86_64; rv:125.0) Gecko/20100101 Firefox/125.0"

However, its fingerprint is a TLS handshake is performed by Java's JVM, which produces a signature like Java 1.8.x or Java 21.x not like firefox. This is the specific reason its getting blocked, because of the missmatch.

Cloudflare is correctly blocking it because it essentially is holding a sign that says "I didnt bother to configure a proper tls fingerprint, im the most obvious bot possible, please block me" and its getting blocked.

Jdownloader Java TLS stack -> cloudflare edge -> {java tls on a firefox user agent} -> block / bot score too high -> BLOCKED

However if you use cloudflare's warp

Jdownloader Java TLS stack -> cloudflare warp endpoint -> warp's tls stack -> cloudflare edge -> {warp's tls stack on a firefox useragent} -> block / bot score not effected by tls fingerprint -> allowed

warp still sends origin ip to edge (anonomized) for your bot score, so if your origin ip's reputation is too poor to load cloudflare over a traditional browser then ofc you will still be blocked. warp only fixes jdownloader's poor tls fingerprint stack that raises the score enough to give the potential for allowing it to work.

Edit: some reading comprehension issue on the commenters. I said cloudflare warp is the fix and apparently people cant see this? You connect to cloudflare warp and it works. idk what the issue is that 4 separate people got confused.

Edit2: some people were complaining about not giving a tutorial of how to use cloudflare warp. It is an on off switch with zero ambiguity. Copy and paste "cloudflare warp" into your search bar, install it, and toggle the "on" switch. I am surprised anyone had trouble with this.

I want to get big for dating

I started at 300lbs and am at 215 lbs now, 30s, male, 6'2". I work out. I unfucked my diet. I am still losing weight and on my way to 180 or 10% bodyfat.

I don't think I need reta or a GLP because my hunger isn't an issue really. I want to get big. Like top 10% of males muscle mass big.

So I was thinking of continuing down to 10% bodyfat and to go onto one singular generational bulk and cut cycle. Go to a "wellness" clinic and get testosterone because my hormones would be rekt.

But that might not be enough. Is there anything in this space that would mimic the effects of anabolics but be legal? Usa. Im already in my 30s so I cant just do 3 or 4 bulk cut cycles. If im going to find a girl I need to do it in the next two years​. Thats my timeline and I want to get myself into a top physique that would do well dating. Currently I'm invisible.

I've been weight lifting on the way down but got to the point where I don't get stronger. It's been 8 months and since my calorie deficit is so big I stopped progressing two months ago in weight.

215 - > 180 is 3 months, maybe less if I have more muscle or less fat than I think. ​

Then I have a year or two to get a lot of muscle on my frame. Data shows attraction peaks at lean with high muscle mass and I have comically bad social ability.

What do you​ think? ​

I have a 5090 and some wireless ap handshakes, dictionary doesn't work.

How viable is brute forcing on a 5090?

Assume password is 10chars, including special but not characters you cant type on a us keyboard. ​

N64-systemtest

Hey, I bought my analogue and it works great. I am trying to get my Everdrive to run the n64-systemtest like in ​kaze's video.

https://www.reddit.com/r/n64/comments/1pogfhj/kaze\_emanuar\_details\_problems\_with\_the\_analogue/

I can't seem to​ get it to run but the Everdrive works for every other game. I want to see if the updates have had any impact on accuracy and can't run the test ROM.

Has anyone gotten it to work? Is there something I can do? I already turned CRC check bypass off, but when I launch it I get nothing. I set my a3d to do "n64 hardware" and still no dice. I cant get it to boot. Can someone else get it to boot? ​

Older Everdrive on analogue3d? Gift for my mom

My mom is medium-low tech savy, but not omega tech savy. Operating a real n64 with a everdrive is trivial for her​, so she can handle a few menus.

I have been using the HDMI out n64 mod chip, which is alright, but here we are in 2026 and I wanted to try some future technology.

Tldr: we have an older everdrive. Its not the x series, and has a usb port on the side and card slot on the top. We think this is an everdrive 64 3.0​. The last OS update was in 2019 under their legacy products. We have a real n64 to update the cart but I'm not sure it has one, maybe I'm misunderstanding.

Also, all the OC and patches profiles won't work because it reads the Everdrive as a "other" cart. How difficult and important is looking up a table for what to put on the everdrive? Or is there a way to "load" a game into everdrive and reset the console, so the game boots with the proper patches? Is this important or will default work OK?

Thanks​

BNDogleheads are so backwards holding cash is a better investment.

BND is 1.94% per year in the last 10 years with an 18% drawdown​.

1week Tbills are 2.17% ​if you take average fed rate and then 0.2% for the spread for the bank you get 1.97% with no state tax and no drawdown ever.

Please can someone enter the mind of the bogelhead and explain to me why BND isnt the worst "investment" ever? ​why is this your age in portfolio size?

title. There was a lot of buzz about a server edition in December, but I haven't heard anything since.

Installing on an actual server is possible, but I have to go through a couple extra steps.

To install on a server now, I have to boot the server into rescue mode, start a VM, and feed the VM the raw disks that are inside the server, and cacheyos ISO.

I then boot up the VM and use the installer over VNC. Once I'm done, I reboot the server and it boots up with cacheyos and then I install the correct kernel for my hardware (Zen, Intel, etc) and uninstall the DE so the server does not go into sleep mode. Not terrible but I have an idea...

I feel like if the installer had a webui for the server edition this would be a great way to skip the vm step to get vnc.

Since there are lockpic, muffle, and paralyze spells as a wizard I should be able to complete the thieves guild quest line without actually leveling sneak. Advancing in the fighters guild is trivial for a mage only.

You dont gain experience if you sneak stationary, so I will try to do a playthrough where I *only* level my wizard stats.

-> but what if you run out of manna?

I will use alchemy to make many potions. Chugjugs the wizard, pleased to meet you.

-> but what if the mob is 100% resistant to magic?

There are spells that make target weak to magic. So I use a damage spell with extra steps

Remember to check your rigs for your new hashrate.

I have a 7742 single slot and get 45KH/s on 8x4GB 2400MT/s ram. If i run xmrig --benchmark=1M -a rx/2 i get 35KH/s.

​the projected loss of efficiency for the "asics" are 30% but im getting almost a near 30% penalty. Wtf

Are epycs no good for mining anymore? ​
