computerdork··on DOOM CAPTCHA
Another thing that makes it "easier" is this actually does support strafe, using Option + left and right arrow keys. Still not easy, but more doable:)
computerdork··on Cognitive load is what matters
Also good for having default activities performed on object or subsystem. For instance, by default, always having an object have security checks to make sure it has permission to perform the tasks it should be (have seen this, and sounds like a good idea at least). And also, to have some basic logging performed to show when you've entered and left function calls. It's easy to forget to add these to a function, especially with large codebase with lots of developers
computerdork··on Cognitive load is what matters
Hmm, thinking back, think most companies I worked (from the small to the very large tech companies) had on average pretty good code and automated tests, pretty good processes, pretty good cultures and pretty good architectures. Some were very weak with one aspect, but made up for it others. But maybe I got lucky?
computerdork··on Rosetta 2 creator leaves Apple to work on Lean full-time
Yeah, higher-level math is got to be one of the hardest subjects a person can study. I find it quite a challenging too:)
computerdork··on One surprising psychosis treatment that works: Learning to live with the voices
I thought of the same film, and in the film (if I remember correctly) the John Nash character in the end even uses the same strategy to deal with the hallucinations. To paraphrase, he says something like, he sees them but he knows they are not real, and choses not to listen.

(Oh, and of course, am not saying this is the only strategy for dealing with psychosis, but it is just that it was also the first thing that came to mind when I read this article:)

computerdork··on Rosetta 2 creator leaves Apple to work on Lean full-time
Don't think I have ever heard of the SICP book as my school split all these different subjects it covers into different courses. But looked it up and wow, it goes into a lot of advanced subjects! (recursion, trees, Big O and computational complexity, Data abstractions, Objects, and ends with compilers). That is some survey and it's amazing you were able to work through this in middle school - I was just learning Algebra and the history of the early Americans back then - Incredible

This now makes sense you were able to work on Rosetta 2 mainly on your own!

computerdork··on Rosetta 2 creator leaves Apple to work on Lean full-time
Btw, followup question, and don't take this the wrong way at all, but what is impressive is someone with a mathematical background worked on something that seems to be one of the pinnacles of software engineering: a translator working at the binary level that creates executables interacting directly with the OS. Did you also double in CS back in school? Or did you pick up the knowledge afterwards? Yeah, it seems like a long list: operating systems, compilers, computer architecture, UNIX/MacOS systems-calls and internals...

... not to mention all the performance considerations and optimizations, also requiring a strong sense of algorithms and computational complexity. Wow!

Yeah, seems like most mathematicians (and physicists) I know who go into tech don't get past learning a couple of programming languages and don't have an interest in learning the depths of a how a computer works. Very impressive!

computerdork··on Humans are unreliable models of mouse disease
Hmm, interesting. If this is the case, isn't the article title misleading? It implies that the mice where the problem in the study, when it was the environmental conditions of the tests that the mice that caused the allergies not to show up. Seems like the title should be "Lab conditions are an unreliable model for human diseases."

snorting coke probably gives them asthma:)

Does anyone have a link to the non-paywalled full-text?
computerdork··on Pat Gelsinger was wrong for Intel
Yeah, that is why some outsiders say this is more like an 8 year strategy, it takes time to convert customers.

IMHO, if you have a great product and a market with significant demand, seems like eventually the customers will come - and it seems like this is possible if Intel can retain manufacturing leadership for a few years and build out a better ecosystem to support external chip development by foundry customers, but this of course take time.

computerdork··on Pat Gelsinger was wrong for Intel
This forum is full of engineers and they talk about 18A (I myself am only a software engineer but who took hardware design classes waay back in college, so can understand 60% what they're are saying but am no expert).

https://semiwiki.com/forum/index.php?threads/intel-18a-too-g...

And obviously, many of these posters are like me and have a bias towards Intel succeeding. Still, it sounds like 18A seems like it's on track in terms of the technologies (at least for now)

computerdork··on Pat Gelsinger was wrong for Intel
it is pretty scary. they just need to hold things together for a while longer. hopefully it works out.
computerdork··on Pat Gelsinger was wrong for Intel
Yeah, I worry myself - actually invested some of my portfolio in Intel too, my original belief was so high - But, at least by the forums I checked out, the people who know the technology say it still is really good and on track:

https://semiwiki.com/forum/index.php?threads/intel-18a-too-g...

But of course, the sources may be biased/overly-optimistic/hiding-info.

computerdork··on Why Gelsinger was wrong for Intel
agreed, 18A is supposed to be amazing according to insiders.
computerdork··on Pat Gelsinger was wrong for Intel
Think you're not wrong about these, but think this was the price of 5 nodes in 4 years (these stepping stone nodes are going to be pretty shaky). Yeah, think overall, Gelsinger's done a really good job where it's important, the technology.

Becausefrom what I've read on forums, by all accounts from the insiders, the technology behind 18A is incredible (gate all around transistors, backside power delivery, 3d Chip stacking...) and that in a year or two ,it should put Intel manufacturing a little ahead of TSMC.

Although, have also read that the one problem is that even 18A won't be profitable for a couple years. Yeah, that the problem with Gelsinger's original plan is that 3 years wasn't enough time to get to profitability, but 5-8 (but that it still is a good plan).

computerdork··on Pat Gelsinger was wrong for Intel
Kind of disagree. Have read on forums that by all accounts, the tech in the 18A process is amazing (Gate-all-around transistors, backside power-delivery, 3d packaging tech...), and that they are on the path to catchup/pass TSMC in terms of chip-fabrication performance/power-expenditure in a year or two. Yeah, this is an amazing achievement for such a large company.

But have also ready that to make this profitable is like a 5-8 year plan, not something that is profitable in 3. To me, this is his biggest mistake, he needed to keep the ship sailing at least somewhat smoothly while waiting for this big gamble to pay off.

And eventhough I do agree with you that he made a lot of mistakes, still he got the the most important issue right, regaining manufacturing leadership.

computerdork··on Ask HN: What were the best books you read this year?
Looking forward to it!
computerdork··on Ask HN: What were the best books you read this year?
Catch 22 is one of the funniest (while still having depth) books ever! Have never looked into his other books, will have to check it out
computerdork··on Ask HN: What were the best books you read this year?
when I first read it, felt like it was written in the modern era. Was surprised to find afterwards that it was written in the victorian period.
computerdork··on What were the best books you read this year?
Liftoff was super interesting. The start of SpaceX and the Falcon 1 is an incredible story. Didn't know about "Reentry", will have to check it out!
computerdork··on Ask HN: What were the best books you read this year?
Grendel by Gardner (so playful and creative), Jane Eyre (a classic with wonderful language and intense story), Sapiens (extraordinarily interesting survey of human history)
computerdork··on Agile Is Dead
Yeah, kind of disagree with this. Compared to waterfall, agile is definitely an improvement.

And most teams get the core ideas right in my opinion: small, tight knit teams working closely together, with a "reduced amount" of process (yeah, think the number of meetings in agile is bad, in waterfall, meetings seem like crush you like a tsunami).

Does anyone on HN have a understanding how close this achievement brings us to useful quantum computers?
computerdork··on How I ship projects at big tech companies
Think a lot of comments here (in my humble opinion) have taken the wrong interpretation of this article. Don't think this is a project-manager role, but is, as stated, typically a "tech lead or a DRI role." This means this person is still technical - would like to think this is how I approach my projects at a company and it is super effective.

Specifically then, as a technical person, this means you don't ignore the requirements and just think about the code. Instead, you need to communicate with both your higher-ups and your end-users, in order to make sure the code you're writing matches their needs - in my opinion, requirements is the part that most developers are weakest in, but if they strengthen would make the biggest difference. Get it as close as possible to being right on the first time (it's very rare that this happens but focusing on doing really good requirements increases your chances that you don't create the wrong system).

computerdork··on Wait Until 8th
Just took a look at the app limit features in parental controls, seems really useful:)
computerdork··on Wait Until 8th
No worries that you deleted it, can understand that you want to be cautious with your child:)

Btw, I actually don't have a child so haven't used parental controls, but just found out that they do have an app time-limit setting: https://support.apple.com/guide/iphone/set-up-screen-time-ip....

yeah, I have an app blocker on my iphone to block news websites/apps called Freedom. Essential these days to staying productive - although, don't think this app would work for your child, because it is not very reliable and needs to be restarted every few days.

computerdork··on Wait Until 8th
Very interesting. Was wondering, are there any differences in how independent they are at the same age? Have read that there is a possibility that the smartphone may be contributing to the development of children to be delayed by a year or two. For instance, are your younger children less interested in driving at the same age and doing things on their own.

... although, even if this is true, this could just be that kids seem to be more attached to their parents then they used to be (have read this as well).

computerdork··on Wait Until 8th
Out of curiosity, what are her phone habits like? And, as others have mentioned, you can turn on parental controls to limit what apps she can have on it. Have you done this already?
