xerxesaa··on The radical moral implications of luck in human life (2020)
Sounds like someone read Sam Harris' essay on free will.
xerxesaa··on GitHub Sunsetting Subversion Support
In the many years I've used github, I honestly never even realized they supported svn.
xerxesaa··on Mercedes-Benz workforce to receive record profit-sharing bonus
Supervisory boards are super common in Germany. I am not sure if there is some legal requirement that makes this the case, but you see it at many large companies.
xerxesaa··on Why is Amazon selling fake 16TB portable SSD drives?
While you may be right, I can tell you from experience that what seems simple can sometimes be embarrassingly complicated at Amazon. I previously worked there and my team once spent 2 months adding a new option in a dropdown box. This was on one of the seller-facing pages.

There are parts of Amazon that have a ton of legacy code and ownership between those systems can be a real mess.

xerxesaa··on Ask HN: Are ICs at tech companies usually so concerned about job performance?
Can you share some of those companies?
xerxesaa··on NYC schools block ChatGPT, fearing negative impact on learning
For all the talk of equity, this seems to be potentially a very inequitable policy. You can't block access at home, so this would most affect those who don't have internet at home or don't have a comfortable environment at home to do their schoolwork.
xerxesaa··on Ask HN: How do you manage your passwords in 2023?
You don't have to get an online one. There are offline ones like KeePassXC which are a lot more convenient to use than a file.
xerxesaa··on 72-year-old Congressman pursues a Master's in AI
If this same person was deciding to spend 3-4 hours a day watching Netflix or playing basketball, this would not even be a question. He has a life outside of Congress and I see nothing wrong with using it to further his education.
xerxesaa··on Ask HN: What would you learn if you would have three to six months free time?
Thank you for your service. Out of curiosity, are you doing software stuff in the military or is this just a side hobby? If the former, I'm curious to learn about what kind of work you do. If the latter, why did you not go full time into software?
xerxesaa··on America Should Once Again Become a Manufacturing Superpower
I'm curious what you mean by stable here. Which other country would you consider stable and suitable to set up your manufacturing in?
xerxesaa··on Wild mammals are making a comeback in Europe
Haha, indeed. The "other" Lagos in Portugal.
xerxesaa··on Wild mammals are making a comeback in Europe
Seeing storks with their giant nests atop utility poles on the drive from Lisbon to Lagos was one of the most unique and memorable aspects of my recent trip to Portugal.
xerxesaa··on ElonJet Is Now Suspended
Elon bought the company and took it public. Can't really buy traditional shorts on it anymore as it's a private company.
xerxesaa··on Tell HN: HP printers force you into agreement
I bought a Canon Maxify GX7020 a year ago and I've been quite happy with it. Ticks all the boxes of having printer, scanner, fax, and full duplex on both scanning and printing.

Most importantly it uses ink tanks. They don't last as long as laser toner, but if you want an ink jet, it's great because there is no cartridge. You just fill it up with ink. I also stopped buying HP after I noticed all the scams they pull with their ink cartridges.

As others have mentioned, a simple Brother printer is also a great option.

xerxesaa··on Amazon layoffs now expected to mount to 20k, including top managers
Might still be correct. Levels 1 to 7 are before reaching director. Once you get to director, I believe the performance expectations change. For example, I don't think directors need to be managed out as part of the quotas. I am guessing a lot of these layoffs are going to be done as part of the forced attrition quotas.
xerxesaa··on Jeff Bezos' 127M sailing yacht has completed construction
I can only assume this is sarcasm.
xerxesaa··on Jeff Bezos' 127M sailing yacht has completed construction
Though somehow I still find it unsatisfying that these laborors rely on a single person's decision to buy a luxury item for these wages.

I'm not anti-capitalism by any means, but despite the average person becoming better off, I find it deeply unsatisfying that we have very few mechanisms to control the insane broadening of the wealth gap.

I don't want to rely on Jeff trickling down his wealth through purchases of yachts and random donations to Van Jones. I want us to collectively agree that there must be some ceiling to wealth for individuals. Not putting a ceiling on wealth is effectively not putting a ceiling on power - and we've already realized that power needs to have checks and balances.

xerxesaa··on Artist feeds childhood diary into GPT-3 to have a chat with herself
This sort of reminds me of the Black Mirror episode "Be Right Back"
xerxesaa··on Elizabeth Holmes is sentenced to more than 11 years for fraud
She did get into Stanford. Not sure if that's a great proxy for talent, but I'm guessing she was somewhat strong academically.
xerxesaa··on Mohammed bin Salman: Saudi leader given US immunity over Khashoggi killing
While I think I get the point you're trying to make, one is a murder of a single individual in their embassy. The other is an all out war across a border. Not sure how they are really comparable.
xerxesaa··on Crypto trading firm Alameda Research might be insolvent
Given the recent events of the last 24 hours, what's your updated view on this?
xerxesaa··on Ask HN: Comment here about whatever you're passionate about at the moment
I lost my father to murder several years ago and have been waking up thinking of him a lot this week. Somehow I really found your post comforting. Thank you.

That's fine, but it's one thing to say "I don't know, and therefore I assume it's insecure" vs saying "it's not end-to-end encrypted"

I'm just humbly asking people to be clear about what they know vs what they assume.

xerxesaa··on Communities Now Available
All fair points.
xerxesaa··on Communities Now Available
That's fair. Signal is open source and that certainly helps.

I worked in tech, not legal. I have no idea about what is or isn't shared with law enforcement or anyone else. That's why I didn't address that part.

The frustrating part is people making claims about issues where they don't actually have datapoints to back it up. I try to avoid doing that.

> well, you are wrong.

For someone who is "not following whatsbook closely lately" that is again a bold claim to make.

But anyway, business messages are also encrypted. Businesses are allowed to designate other accounts to receive messages, in which case those other accounts are sent copies of those messages using a different key. It's similar to sending messages to multiple devices. This is disclosed [1] and needed to support things like auto responders.

Group chats are also encrypted using a shared sender key and this is described in the whitepaper starting page 10 [2]

100% agree.

Sure, that's a fair point. Backups were initially not encrypted, but as you mentioned, this option is now available.

Without going into too much detail, I can tell you a huge challenge with encrypted backups is compliance - many people simply do not opt-in to using encrypted backups. It's a difficult line to walk because ultimately you don't want to pester users too much about using encrypted backups either. In case it's not clear, the reason it requires opt-in is because you (i.e., the user) control the encryption keys and therefore you must take some action to write down a key or passphrase. As you may imagine, the average messaging app user is not as tech savvy as the average Hacker News user and many simply don't want to go through this extra step. Even worse, if they opt-in to encrypted backups and lose their keys, they will end up blaming Meta for not giving them a way to restore their message history when their phone gets lost (it's not easy to explain that it's your responsibility as the user to keep your keys safely stored).

Message contents are end-to-end encrypted (but not all metadata is). And no, they are not sent through an unencrypted side channel to Meta. I've worked at Meta on a team that does end-to-end encryption. The company is also very clear about this publicly [1][2]

It's super frustrating that every single time WhatsApp is mentioned on Hacker News, someone boldly makes a claim that it's not encrypted based on hearsay or hunches.
