@crawfax @sharbel Sprinkle in some known data that has already been labelled by a diverse range of people. If you consistently score poorly on that known data, your other answers are given less weight.

> you open a website > it says: "click all the traffic lights" > it takes you 10 seconds > 200 million people do this every day > you weren't passing a security check > you were labeling training data for a self-driving car > google acquires recaptcha in 2009 > deploys it on every bank, store, and government site on earth > turns the entire internet into an unpaid AI annotation factory > waymo is now worth $45 billion > you didn't pass the test. you built it.

Xitter is now busy complying with Australian law, but: - In one instance, it blocked an image, but displayed a preview of a video with explicit adult content immediately below it - Block sometimes kicks in AFTER restricted content is already shown, which defeats the purpose?

@crisisofconsc A family 'friend' moved out and left behind a heavily pregnant cat. I collected mum+kittens and fostered them for several weeks. I suspect our cat, who randomly appeared in our yard one day, was a "hey, you want a cat?" thing, and the 'owner' never really cared enough for him.

What I learned today is that some people, even with the best intentions, take minimal care of their pets. The foster cats I took in (it was an owner surrender) have: fleas, tapeworms, upper respiratory infections, and one with an infected toenail that might need surgery. Their owner thought they were right as rain. 😵‍💫 She actually thought I was odd for requesting a vet visit before taking them in.

@martyrdison Years ago, in group chat, there was a participant who was a lesbian in a wheelchair. Frequently seeking sympathy. After some time, people started asking questions, then her partner informed us that she'd died. Turned out both were played by an able man - also a chat participant.

saw this tweet today about me in middle school and laughed because it’s ACTUALLY partially true: > be me > ugly 12–13 year old theater kid in middle school > have one best friend, (we’ll call her emily) > emily and i meet at musical theater camp > one day she says she has a boyfriend > emo kid, dark swishy hair, exactly my type > then tells me > “his best friend likes you” > suddenly i have a boyfriend too > entire relationship happens over AIM > never meet him because he “goes to another school” > then one day she tells me he killed himself > train tracks, dramatic note, whole story > i’m devastated > my mom starts calling around like the FBI, trying to see if anyone actually died > turns out none of it happened > emily made up the boyfriend, the best friend, the suicide > her mom eventually calls my parents and confesses > never speak to emily again > switch schools out of pure embarrassment because of a middle school catfish ring run by exactly one person

Moving a legacy "stable as f***" application to a much, much newer system. clang: You must fix this questionable pointer arithmetic code OS: [randomly segfaults] Valgrind: Hey bud, there's a buffer overflow, you're also sending unitialised data It "worked" on the old system.

@BonesMoses @loyalmoses I acquired a CD-ROM drive around the same time, although it was given to me. It was CD player size, with a big fat SCSI cable going to an ISA card. (I realised later that this would have cost a fortune new, and was probably worth a bit, even used)

@loyalmoses I bought a CD drive specifically for my BBS in '94 or '95. I started with So Much Shareware! Vol. 3 or something and upgraded whenever I was at the local computer shop. 😭

When I ran a multi-node BBS back in the early 90s, I started with a 40MB card hard drive. The BBS was so busy, and we didn’t have enough storage, so we had a published schedule, a list and a request system to unmount and mount two 1.44MB 3.5” floppy disks throughout the day. This allowed us to serve far more downloads… what a crazy time that was. 🤓

@AmazonHelp Yes, I've now removed it, but it's been dormant for years. Amazon, for some reason, decided to start using it as primary??? Which then made it my problem to fix.

Hello, we're sorry to hear about this. If your main payment method has an issue, such as declining etc., then we will try one of the other available payment methods on your account. If this is an old or expired card we advise removing it from your account, and updating your payment method. You can learn more about this here: amzn.to/3NrsLaF. Thank you. -Morgan

Dear , <-- blank name We've been charging card X for ages, but we thought we'd randomly switch to another card you haven't used for 3 years. So yeah, the charge was declined for some reason. This is a "you" problem, so please fix. Thanks, Amazon

@ryzerth This seems like: 1. Not doing some basic due diligence before settling on a project name or 2. Being aware, but assuming that the name could be acquired Even in the case of #2, there's still those numerous high ranking search results pointing to the OG. It makes no sense.

Someone wants me to rename the Microkernel I wrote when I was a kid... Brother, I don't give a shit AIs see my decade old project more than your slop, you should have checked that before naming your shit. I'm not changing history because of your naming incompetence.

@tsoding I often use "if (1==2)" to make it stand out as something unusual, and be absolutely clear that this condition will never be satisfied. I do like "if (0)", might give that a try.

Very often I want to temporarily disable a piece of code. I comment it out, but then I'm faced with a problem that since the code is never compiled it gets "stale". Some functions it uses may have changed and it is never type checked. So the next time I enable it, it doesn't compile and I spent a lot of time fixing it. The solution I came up with so far is to "comment out" the code with the runtime `if (0)`. The code will never be executed, the optimizer will very like eliminate the code entirely, but before doing so the compiler will type check it, and will force me to fix it on the spot.

@Andrew___Morris Yes, the threshold seems far too low. A few blackholed packets to port 22 should be noted, but shouldn't be sufficient to auto-generate an abuse report, as the source can't be verified. Connect and negotiation resulting in a failed login attempt? That's more like it.

@levelsio I guess the host logging all outbound connections would definitively prove that your VPS didn't initiate the claimed abuse, but that's going to be difficult at scale, and it's ethically questionable.

Any way I can avoid my IP getting spoofed? Can hosting providers check if abuse reports are based on real or spoofed packages?

@levelsio @Hetzner_Online How do you even respond to a superfluous abuse report? - "idk what's happening" - "k, carry on" I ran a TOR exit node at Hetzner some years back. That didn't last long. :)

What's scary is how easy it is to take down anyone's site if they're hosted on @Hetzner_Online I'm the biggest Hetzner fan btw so that's why I say it But you can just send an abuse report to any site on Hetzner and if the site owner doesn't reply within 24 hours they generally block the server IP taking down the site It happened to me this week for the nth time! The question is if you're a solo biz like me, if you get to that email on time Essentially you have to be on standby every day of the week forever just to keep your sites up @Cloudflare is much more reasonable with abuse reports, taking the side of their paying customers first, and only taking down if forced by a court (as it should be!)

@financedystop Ehhh. I wanted to add a rear courtesy lamp to my mid level sedan. Had the cutout for the lamp lens, but once I removed the console I realised there was no harness. Ford said I had to pay $230 for a high level harness, just to get those 2 wires going to the rear lamp.

He discovered that behind these harness panels are hidden buttons for cargo lights, fog lights, and other features. Even if the car wasn’t purchased with those upgrades, the wiring is already there and you could just “upgrade” yourself

@RosannaPansino I've had the same IP address for years. It's never watched a MrBeast video. One day I cleared cookies and loaded Youtube. Two or three MrBeast videos featured in the first few rows. Does he even need to buy views when Youtube feed him to us by default?

Had the team run some tests! Apparently, if you spend $1 Million (the amount MrBeast gives away in a video) you can buy nearly 600 MILLION views using YouTube Promote. This is a screenshot of YouTubes backend where you can put how many views you want to buy for your video. Turns out it’s pretty easy to inflate views and subs when you’re a billionaire with some extra cash to spend 💸📈

@val_nemo @kingofknowwhere How do you get that 5TB of data to your rented CPU? At 100Mbytes/sec it would take half a day to transfer.

Why does Aliexpress send me multiple detailed updates about movement of a package that is currently transiting another country and won't see my local airport for at least another week?

@0xSweep No one (as far as we know) has a way to see into the future. I was a relatively early adopter. If I'd HODL'd every Bitcoin I ever mined or purchased, I'd be a millionaire. Would life be nicer? Yeah. Do I beat myself up because I didn't predict the explosion of Bitcoin? Nah.

Everyone knows about the 10,000 Bitcoin pizza but nobody talks about the other 150,000 BTC he wasted after Before the famous pizza order, Laszlo Hanyecz invented GPU mining for Bitcoin Which made it possible for him to mine thousands of BTC per day Satoshi personally messaged him about it, and was worried it would break the network Laszlo's response: "I feel like I crapped up your project" He kept buying strangers dinner in Bitcoin until he couldn't mine fast enough to keep up His wallet has a total volume of 162,864 BTC That's $10.7 BILLION in today's value and $20.3 BILLION at the peak price of Bitcoin His balance now? 0.00018 BTC around $12 The guy who invented Bitcoin mining actually wasted BILLIONS Probably the biggest fumble in the history of Bitcoin

@AaronDodd @DailyMailAU She would have been trained and had it repeatedly drilled into her over her 14 years that patient records are private. The extra restricted access step means he's probably marked as a confidential patient, but that wasn't enough to make her reconsider!? "lolz everyone does it"

Point of order on this @DailyMailAU. The staff were sacked because they illegally accessed a patient's confidential health records *NOT* because they were Dan Andrews' records. That's actually incidental. #auspol mol.im/a/15583153

United States Colorado Sen. Matt Ball and Rep. Amy Paschal have authored bill SB26-051. SB26-051 would require Operating System, such as Windows or Linux, to perform age verification on users which then third party apps can leverage via API to ensure someone's age.
