lexandstuff··on Detecting the use of “curl | bash” server side (2016)
Before SSL certs were as ubiquitous as they are now, we used to warn about the danger of curl to bash for unsecured URLs, as it's a vector for a DNS spoofing attack.

Now that nearly all URLs are HTTPS with valid certificates, the remaining risk seems to be that the host could be intentionally or unintentionally doing something destructive.

Sure it would be great to review the code of every install script before you run it, but as you allude to, it isn't practical.

Maybe something like ChatGPT could help us here?

lexandstuff··on Ask HN: 90s kids happily less connected?
I'm not observing this at all. Most of my Millennial family and friends are on Instagram, regularly posting Stories about their family or travel. Many 30-year-olds+ are as hooked on short-form content (TikTok, YouTube shorts, Reels etc.) as the younger generation, but the latter are more likely to contribute rather than passively consume.

Messenger apps are very popular, with WhatsApp still being the number one choice.

I don't know anyone outside of tech who regularly posts on Twitter. Most ignore it completely.

lexandstuff··on George Hotz: Resigned from Twitter Today
Unbelievable. George appears to have deluded himself into thinking he was an order of magnitude smarter than all his predecessors at Twitter. It's incredible what social media popularity can do to a person's ego.

I'll bet Musk wishes he didn't haphazardly fire so much of Twitter's talent. He could use the help right now.

lexandstuff··on Twitter has re-suspended ElonJet account
I find the tabs on the Explore page return errors about 20% of the time. Also, yesterday Trending was offline for an hour or so, and random keywords like Telegram were blocked and then unblocked [1]. It's about as broken as you'd expect for a company that just lost ~70% of its headcount.

lexandstuff··on Disputing a Parking Fine with ChatGPT
Yes. Rereading it, I think my prompt wasn't quite correct. I should have said: "write a letter to dispute" instead of "requesting to dispute."

Although it went through 2 layers of bureaucracy, so it may be correct if you consider I was requesting the Regulatory Admin pass the dispute to the Appeals Officer.

lexandstuff··on Wickr Me is shutting down December 31, 2023
In Australia, the majority of drug deals are organised on Wickr. It's so popular amongst criminals, drill rappers mention it in their bars [1]

This is going to be a huge loss (or gain if you're in law enforcement, I guess).

lexandstuff··on A configuration management system for computers that are pets, not cattle
You mean Cattle, not Pets is the general mantra, right? Or have things changed a lot since I was last doing Ops?
lexandstuff··on Tesla engineers were on-site to evaluate the Twitter staff’s code, workers said
It seems almost inevitable it will go the way of Tumblr, Friendster, Hi5, Bebo, MySpace, Orkut, Google+ and soon Facebook.

Social networks don't have a particularly long life expectancy.

lexandstuff··on Since becoming Meta, Facebook’s parent company has lost $650B in market value
The metaverse is already here. Roblox has 24 million daily active users. The question really is: can Meta get in on some of that action?
lexandstuff··on Ask HN: Am I the only one not caring about GitHub Copilot?
I trialled it. I found that most of the code it wrote was wrong so I didn't bother paying for a subscription. It was like pairing with a super enthusiastic developer that is eager to write code at every opportunity but doesn't understand what we're doing.
lexandstuff··on Google has most of my email because it has all of yours (2014)
Sounds like an insane inconvenience. Sorry, what was the point of doing all this again? Just to prove you can?
lexandstuff··on Meta Quest Pro
I'm the opposite. I find it very difficult to communicate with someone who doesn't turn on video. It's tough to gauge whether the other person understands what I'm saying or if we're still connected as I talk. I can never get in the flow.

I never liked phone calls and always preferred face-to-face communication, maybe that's related.

lexandstuff··on Xonsh: I don't remember how to write a for loop in Bash [video]
Conditional statements are even harder to remember. How many square brackets do I need? 1 or 2? Do I use == or -eq? Where does the semicolon go again?
lexandstuff··on Why aren't there C conferences? (2018)
I've been to plenty of conferences, and I agree with you. A talk seems a poor way to consume information compared to a blog or a video. Combine that with seeing multiple talks on the same day, you basically retain nothing.

The best you can do is note which talks seemed interesting and then do more research on the topic later on.

People say they're good for networking, but I find it has the same problem: you end up meeting a firehose of people for moments at a time, and it becomes near impossible to remember which to follow up.

lexandstuff··on Ask HN: In 2022, what is the proper way to get into machine/deep learning?
Fast.ai [1] would still be my course of choice, especially for a strong programmer.

After completing that, I think Kaggle competitions are a great way to master your skills.

lexandstuff··on Stranger Things is being edited retroactively by Netflix?
Texas had 1,586 books banned from high school libraries [1] in the last year. Is that the kind of "woke crusade" you're referring to?

lexandstuff··on I'm an addict
Great. Another popup to dismiss!
lexandstuff··on Ask HN: Do you find it challenging to talk to your users?
Some people are willing to give product feedback others aren't (like me). Recognise the latter quickly and don't bother them.
lexandstuff··on Ask HN: Do you find it challenging to talk to your users?
If you do this, please please please include an unsubscribe option on the email that doesn't require a login to "manage email preferences".

As a user, I do not want to receive an email like this at all, but I will forgive one if I can permanently opt-out with a single-click.

lexandstuff··on If Google sucks then why is everyone still using it?
I agree.

People have forgotten that Google searches for tech stuff 10 years ago used to exclusively returns results from sites like Experts Exchange with solutions behind paywalls. I'm glad Google did something about that. And, of course, thankful that sites like Stack Overflow came along.

lexandstuff··on Germany: Data retention to be abolished
So you'd like Dropbox to "protect your data" by deleting it?

I'd rather see my family photos leaked to hackers than see them purged from existence forever because I forgot to log in enough.

lexandstuff··on Roblox has been down for over 24 hours
Seems surprising that it would cause 24+ hours of downtime. My guess is they're recovering data from backup.
lexandstuff··on Roblox Service Disruption
Yes, but Roblox has managed to capture a younger audience (6-13ish). There's lots of money to be made in every other age group
lexandstuff··on Australia’s new mass surveillance mandate
Melbourne has been in lock down for over 200 days. Sydney is not that far behind.

Massive amounts of people are unable to work, and a lot of us haven't seen our interstate family in almost 2 years.

A few months before Covid started, 180,000 km2 of Australia was burned to the ground, enshrouding our capital and major cities in smoke, making breathing outdoors almost impossible, causing a mass shortage of P2 masks. Many people died. Many more lost their houses.

What sort of additional hardships do you want to prescribe for Australians exactly?

lexandstuff··on Risk Assessment of GitHub Copilot
Preach. This is what chasing 100% test coverage looks like.
lexandstuff··on Ask HN: Predictions for 2021?
Interesting. I predict the exact opposite: birth rates will decline dramatically. I'm not alone in that prediction. According to this article, birth rates have already started to decline in the US: https://www.theatlantic.com/family/archive/2020/11/covid-19-...
lexandstuff··on Regular cannabis use were associated with poorer cognitive performance
Don't want to create a new thread for this, but my suggested title is: "Moderate adolescent cannabis use may have adverse effects on cognitive functioning"
lexandstuff··on Fast.ai releases new deep learning course, libraries, and book
Yes. I would recommend the fast.ai course linked above. It covers all the essentials of deep learning and some classical machine learning. You'll have enough breadth of knowledge to know which areas you'd like to explore in more depth and all the skills you need to build practical projects.
lexandstuff··on Ask HN: What’s a big trend we should all be following?
2 decades old now. Wiley and Dizzee Rascal have tracks dating back to the year 2000.
lexandstuff··on You can fool some of the people, all of the time
Getting a vote instead of a bullet to the head seems like a pretty significant upgrade to me.
