ksml··on Past Time to Tell the Public:It Will Probably Go Pandemic, We Should Prepare Now
Unless you are doing work that involves lots of tiny particulate matter (and even if you do), I think 50 n95 masks is pretty darn excessive. Most people don't even wear them correctly.
ksml··on Apple engineer killed in Tesla crash had previously complained about autopilot
Yikes. Not sure where you are located, but that sounds pretty frightening. Best wishes!
ksml··on Apple engineer killed in Tesla crash had previously complained about autopilot
You almost crash at least 4 times a day?? I have no stats but I don't think that's normal. You should be driving much more defensively if that's the case.
ksml··on Britain knows it’s selling out its national security to Huawei
I feel like this is some slippery slope logic. Just because human rights violations exist elsewhere doesn't mean we should ignore human rights violations in one place.
ksml··on De-Anonymization via Clickjacking in 2019
I think the captcha box is the Facebook comments box restyled. I'm guessing uBlock or Firefox containers are protecting you.
ksml··on Indiana manipulated report on Amazon worker’s death, investigation says
This article feels a little fishy to me. The title says an "investigation says" "Indiana manipulated a report," but there's no evidence to suggest this besides one person's claims and it doesn't seem there was any official investigation into whether the report was manipulated. Also, all the figures appear to be an order of magnitude off... All this fuss over only $28,000? And a single $1,000 donation? That's a drop in the pond. I wouldn't be surprised if there was indeed a lot of corruption in bidding for Amazon's HQ, but something doesn't add up here for me.
ksml··on Slack’s new WYSIWYG input box is terrible
I want to chime in with one editor that I think nailed a markdown WYSIWYG: https://www.typora.io/

It's hard to explain the concept with just words, but I will try: While you're typing, markdown is fully exposed, but when you move the cursor away, the formatting characters disappear and you just see pretty formatted text. As soon as you move the cursor back to the formatted text, the markdown reappears so you can edit the plain markdown syntax.

I've been using this editor for two years and I think the developers were really clever in this implementation; I've never experienced any unexpected issues. Slack, on the other hand, has been driving me absolutely crazy. (Try changing an inline code block after you've created it. Easy in Typora, a nightmare in slack.)

ksml··on Local-first software: you own your data, in spite of the cloud
> If it's used by let's say 100users, It means one user has only 0.16core + 0.64GB memory. So an average laptop(4cores/4GB) or phone(4cores/1GB) is way faster.

This is overly simplistic. You're pretending that cores/memory are "allocated" to users, but really, a user might only make a few tens of requests, and the server only needs to spend a second or two servicing each request. On a server with only 100 users, it could very well be the case that a user has all 16 cores + 64gb available at the time they make a request. Also, as another commenter pointed out, you could use a large chunk of that memory for shared resources, and then each request might only need a few mb of memory to service a request.

ksml··on A $1.2B law to boost US quantum tech
Do you have any sources for these statements?
ksml··on Stanford CS9: Problem-Solving for the CS Technical Interview
This is a _single_ pass/no pass unit out of 180 required to graduate. Stanford absolutely focuses on creating great engineers (or computer scientists, for those more interested in the math or theory sides), but it still helps to have a small course pointing out tips and things to look for in the interviewing process.
ksml··on Stanford CS9: Problem-Solving for the CS Technical Interview
Oh, come on. I think you are exaggerating quite a bit here. This is a single pass/no pass unit out of 180 units required for graduation, and, as a Stanford CS student, I can assure you the other classes are extremely rigorous. I don't see a problem with a one-unit class designed to help build confidence and demonstrate your skills to an interviewer. If you think that such a class shouldn't be necessary, then blame the current interview system, not all of higher education. Higher education has its problems, but this is hardly grounds to claim it's in "steep decline."
ksml··on To Stay in Love, Sign on the Dotted Line
This is terribly unhelpful. Can you at least elaborate on what you mean?
ksml··on Oscilloscope pong for 1 or 2 players
If someone could explain how this works to someone who only understands basic circuits, that would be much appreciated. How does it maintain state and draw shapes on the oscilloscope and trigger sounds with such basic components? Amazing!
ksml··on How to find size of an array in C without sizeof
I would be extremely interested to hear how you found this bug. Sounds like a difficult bug to track down, and I always learn from good debugging stories.
ksml··on Computer Vision Syndrome
I looked into break timers a while back, but I wanted something really simple that I didn't need to install. I wrote a blog post about how to make a simple break timer with OS X notifications and AppleScript: https://reberhardt.com/blog/2016/02/09/a-dead-simple-break-t...
ksml··on Music theory for nerds
I don't think the author was necessarily proclaiming that it's absurd, only that it seems absurd from his/her beginner perspective. He/she was very up front about not having much experience, so I think this is totally reasonable (and expected)
ksml··on Mozilla Thimble
I'm confused. Why would you make a switch if you have been satisfied? Also, this doesn't seem like it's in the same category as Brackets; this seems more in the educational space.
ksml··on Show HN: A minimalistic cloud provider
It's a dollar or two cheaper than DigitalOcean, with hybrid drives instead of SSDs. I don't really see any appeal; DigitalOcean already pitched this years ago (and has done very well)
ksml··on Microsoft Pix
Ooh, they mention it includes Hyperlapse! I haven't looked into Pix too much so I don't know if this is a full implementation (someone commented on an unnatural-looking stabilization demo, but I think it was just a poor choice of an example), but Hyperlapse is one of the coolest research projects I've come across:

http://research.microsoft.com/en-us/um/redmond/projects/hype...

The video demo there is worth checking out.

ksml··on With the iPhone 7, Apple Changed the Camera Industry
I don't doubt that the iPhone will shrink the market for DSLRs eventually, but I don't think it's going to do it to a significant extent just yet (not much more than it already has been). I'm skeptical that people buy DSLRs just for the bokeh, and anyways the samples that they showed look nowhere near as good as real bokeh from a nice lens. I think non-photographers buy DSLRs because they still take better pictures than smartphones in certain situations, particularly when an optical zoom would be desired (e.g. A kid's performance or graduation). The new iPhone comes a step closer to potentially addressing some of those situations, but it's still limited; 56mm full-frame equivalent is not really all that zoomed in, and AFAIK there isn't yet any way to zoom between the 28mm lens and 56mm lens any better than traditional digital zoom (i.e. cropping and rescaling).
ksml··on With the iPhone 7, Apple Changed the Camera Industry
I agree that the smartphone killed the point and shoot industry, but I think it's pretty far overboard to say that Apple is revolutionizing the camera industry with the iPhone 7. They added another lens, which is certainly nice but not revolutionary, and they added some depth of field effects, which are nice but look pretty bad compared to actual shallow depth of field.

Edit: Also, you definitely don't need to fire up Lightroom to share photos from your DSLR; I think practically any DSLR can shoot JPG. Many DSLRs can also share photos to phones via wifi or Bluetooth these days. Mine didn't come with such a feature, but Nikon sells a $20-30 adapter that adds that capability.

ksml··on iPhone 7
This is happening to me on Android (Chrome); the page completely freezes and can't be scrolled for 3-5 seconds. I assumed it was my phone reflowing or something, but I feel like it shouldn't be that bad, and if it's also happening on MBA, it really shouldn't be that bad
ksml··on iPhone 7
I don't know about you, but to me, 2013 is relatively recent. Plenty of cars don't have that capability.
ksml··on Ask HN: Best place to learn GPU programing?
I found Wen Mei Hwu's "Heterogeneous Parallel Programming" course on Coursera to be an excellent class: https://www.coursera.org/course/hetero
ksml··on End to End Learning for Self-Driving Cars [pdf]
This is a great point. Reminds me of how airplanes have redundant flight computers and compare the outputs of the computers to determine if one might be faulty. https://en.wikipedia.org/wiki/Fly-by-wire#Redundancy The output of different self driving models could be compared to handle more difficult driving situations -- I never thought of that.
ksml··on How the Apocalypse Will Bring Out the Best in People
The accounts are worth reading. It sounds like people band together when facing a man-made disaster as well. He notes that prepping was useless since the preparation didn't last and everyone depended on each other anyways
ksml··on Aphantasia: How It Feels to Be Blind in Your Mind
This is slightly off-topic, but I just wanted to say thank you for writing this article! I never knew people thought/imagined in so many different ways.

Personally, like codingdave, my "milk voice" is my own voice. I can "hear" my voice, with texture, inflection, and everything, as if I were reading my thoughts out loud. The milk voice doesn't have to be my own; I can vividly imagine the voice of anyone else I've heard. I have often wondered about that; how is it that with so little sample data (hearing someone talk for only a few seconds) I'm able to imagine them saying _anything_, with any inflection?

ksml··on Aphantasia: How It Feels to Be Blind in Your Mind
> For example: I'm sure you can imagine what it felt like when something really funny happened to you, right? And you could probably also remember listening to a song you heard on the radio. Now - recall what it felt like when you were on a beach (or a snowy mountain), and recall what it sounded like. If you cannot remember, imagine the feeling of the sun, sound and imagine the sound you might hear.

Did you read the whole article? I'm pretty sure he cannot do these things. He mentions he can't really imagine music or sound either and has a hard time recalling experiences in general.

ksml··on Aphantasia: How It Feels to Be Blind in Your Mind
> There was a (possible hoax) story a while back about a guy who could only remember the previous 15 or so hours of his life. He kept journals and had to jog his memory daily.

This is probably not the same condition, but those with anterograde amnesia cannot form new memories and will forget things within minutes. The movie Memento was about this, and Oliver Sacks wrote about a man with it in "The Lost Mariner." I could definitely believe that story... Strange and awful things can happen to the brain :-/

ksml··on Namecheap live chat social engineering leads to loss of 2 VPS
One option is to look at when the user last logged in. I would be a lot less pissed if an account that I've never touched in 10 years got compromised... I'm probably going to remember my info for recent accounts and want it to be difficult to social engineering those
