  • Memory safety for one. C is very memory unsafe and that has been the source of a great, great number of software vulnerabilities over the years. Basically, in many C programs it has been possible to force them to execute arbitrary code, and if a program is running with root privileges, an attacker can gain full control over a system by injecting the right input.

    I have very limited knowledge of rust, but from what I remember writing memory unsafe programs is nigh impossible as the code won’t really even compile. Someone else with more knowledge can probably give more detail.


  • I don’t think they are running inefficiently. I do think they have more than enough money to keep themselves going for many years to come. Also, the lack of inclusiveness in the editing is the reason I don’t donate. Nothing like making an article contribution only to have it quickly reverted by some control freak editor from the inner circle. Wikipedia is not actually what it claims to be. It’s slightly more open than a real encyclopedia, but not much.



  • There were signs it was coming, but I didn’t really accept it. When it did happen it was pretty distressing, but I had been planning to leave anyway. It ended up working out because I got to leave with some extra runway. They gave us 60 days notice, during which time we collected paychecks. I didn’t work at all during this time though. Instead I searched for a job. At the end of the 60 days we got about 6 weeks worth of pay, a prorated bonus, and our vacation days. I ended up finding a job that paid 3x as much before my 60 days were up and was able to pocket the severance money rather than live off it.



  • Yeah, there shouldn’t be health insurance, just health care. Some things are uncertain like whether you get in a car accident, or whether a weather event causes damage to your house. Health problems are not uncertain. People will all have them. Just spend the money on training and hiring doctors and nurses to treat these issues in a large enough quantity that the care is sufficient.





  • If you watch WWDC, they shared how it works. They have a private cloud that does not persist data on it, only processes it. Also, it’s audited by a third party and there is a cryptographic mechanism that will not allow your request to be accepted unless the server software has been publicly signed by the auditor. At least, this is my best understanding of it from what I remember.

    Also, in the same presentation they announced that you can now lock your Apps and hide them, which will keep its data out of the OS search results. I am fairly certain this also means it’s opted out of ML/AI processing given that any LLM would rely on the same search index.



  • Look up the model number. There are some that maintain 100% capacity down to negative temps, and there are some that lose capacity as the temperature outside drops. You can look up something called a “submittal data sheet” to find out the output capacity at different temperatures.

    Capacity is measured in BTUs. So, if the heat pump is a 30,000 BTU model and it’s 47 degrees outside, it may produce 30,000 BTUs. However, at 17 degrees outside, it may only produce 20,000 BTUs. At -5 F, it may only do 10,000 BTU. Other models will keep 30,000 BTUs all the way down to -15F. The trade off is they use more electricity. Checking the data sheet can help you figure out what your model is capable of.

    Mitsubishi is generally regarded as the best brand and they sell a line called “hyper heat.” These maintain capacity in low temps. Other brands have similar.


  • What new ideas exist that some “programmer” can build themselves with a laptop and an energy drink? CRUD web app ideas are largely exhausted and their functionality has been absorbed into 5 major companies. If an idea is truly new and shows promise one of those companies will quickly clone it and integrate it with their platform, so their existing users have minimal effort to start using it. They won’t use your new app. Signing up for services is a pain.

    Starting a tech company these days is going to be more and more complex. You can’t get by with a web app you hacked together in an afternoon. And, it will likely need to involve AI to attract investors. You also need to have plenty of capital to procure users via marketing.






  • I mean, it’s more than that though. You could sell the property at a loss or have it foreclosed on. Selling incurs fees of roughly 6-8% of the selling price… so, even if you sell it for what you bought it for, you could still be in the red. You might walk away $100ks in debt.

    You can be jealous of people in that position of having multiple properties all you want, but ask yourself if you were in their position whether you would somehow respond differently to the incentives and risks?

    If you had enough money to buy multiple properties what would you do?
