gargarplex··on Show HN: DontBeEvil.rip: Search, for developers (API, expressions, CLI)
I guess blogs that are linked-to in non-killed HN comments should probably be crawled a bit. Have you considered using social user karma (this could be a 1-10 score uniquely calculated for users of each of HN, Twitter, Reddit as long as it's built in a modular way) as a weight in a PageRank style schema?

Here's how I am going to evaluate your search engine. Yesterday I searched Google for "get dynamodb table row count" and found this URL, https://bobbyhadz.com/blog/aws-dynamodb-count-items, which provides a terrible recommendation involving a full table scan.

With DontBeEvil, I didn't find the correct answer, to use the describe-table API.

If you really plan to dedicate a year to this, I would strongly encourage you to re-post again as soon as you have a strong update. Right now this has potential to provide value but really does not. So update us when you have confidence that you might be providing value! But we think you're on to a great opportunity.

gargarplex··on Ask HN: What can I do with 48GB of RAM?
This is the kind of blog post that just ignites a passion for serious software engineering.
gargarplex··on Ask HN: What can I do with 48GB of RAM?
Can you please describe an example of where an application might be memory bandwidth bound, and what engineering techniques might be used to circumvent this restriction?
gargarplex··on Ask HN: What can I do with 48GB of RAM?
Whoa. Super interesting! Maybe even useful for compiling during development ... develop in workspace, use unison to copy over to the ramdisk, then do all builds from the ramdisk dir?

Would you agree with this article's recommendations regarding ramdisk setup? https://www.linuxbabe.com/command-line/create-ramdisk-linux There seems to be controversy in the comments as to whether tmpfs is a proper ramdisk - although no clear tutorial as to a better method. Interested to learn more!

I am mostly concerned about the mutations coming out of the Omicron contagion than the Omicron variant itself.
gargarplex··on Ask HN: How to know if you should stop doing startups?
You are clearly modestly competent at entrepreneurship and to the point where it's worth pursuing because of the high opportunity cost. I think it would be wise to take some time as a salaried employee while identifying and correcting the gaps in your skillset.

gargarplex··on 8 year girl found a way to avoid online lesson by exploiting Zoom password block
> willing-to-experiment-by-pushing-all-the-buttons

This is a great way of putting it and something I haven't thought of before. Mostly, I have been guarding my 2yo from pushing-all-the-buttons because I'm scared of her breaking something expensive (air purifier) or hurting herself (elevator). But I want to foster this sense of creative exploration.

She has taken a lot of interest in my Macbook (lots of keys to press, and she sees me using it) but zero interest in the cheapo tablet I bought her.

Any advice?

gargarplex··on 5 years of leetcode with no progress. I'm giving up
Strong +1 to this. I passed the FAANG interview after solving 100 leetcodes, mostly medium.

Being able to show up and do the work is table stakes –– and yes, I actually write efficient algorithms in my day-to-day because we process massive amounts of data. But the algos I write were invented 50, 60 years ago. My leetcode study process was to look up the solution and then memorize it through rote practice. Why reinvent the wheel? I'm not trying to win a Turing prize here.

But your intellectual mettle and day to day happiness in the company is tested by your ability to deal with people.

Zuckerberg wasn't a mediocre programmer. He was an accomplished programmer who had shipped industry-level code by the time he was in high school. Adam D'Angelo was a USACO gold medalist.

gargarplex··on I Hacked into Facebook's Legal Department Admin Panel
I macro agree with your point about leverage although I'd like a bit more insight here...

"You can give them a hint as to what it is, to vouch for the legitimacy of your finding, but Facebook has one of the better-resourced security teams in the industry, and they're just going to find it themselves and shut it down without paying you anything."

Wouldn't that cost Facebook much more than $7,000?

gargarplex··on PG and Jessica
On the one hand, you have a renaissance man (RISD-trained painter and Harvard-minted CS PhD) who authored On Lisp and started up and exited successfully with some of the most respected technologists as partners (Trevor Blackwell, Robert Morris). On the other hand, you have the author of Founders at Work, someone who not only thoroughly interviewed tons of successful founders (& bootstraped a pattern-matching capacity) but also has a reputation for a world-class EQ that built community and kept bad apples away.

So, yeah, the DNA of the founding team matters a lot. Seems like for scaling companies (like Y Combinator, itself, is a company – and by Sam's definition of creating more value for others than itself, has become a platform) – traits are extremely heritable (not so much the case with children!)

I'm with you on this analysis. CAFO or factory farms have made meat much cheaper; likewise with globalized supply chain. Abundant Florida waterfront real estate – and low cost of air travel – has contributed to a comparably increase in supply of seaside villa substitutes.
gargarplex··on GitHub Is Down
Of course, ideally it would be a Terraform (or similar open source stack) script so it's not dependent on AWS as a vendor... I have experienced the real pains of vendor lock-in, even with cross-region there is opportunity to improve robustness
gargarplex··on GitHub Is Down
I'm also thinking that it would be easier to use git-hooks to push to AWS CodeCommit (in a random region that GitHub is unlikely to use) paired with CloudWatch events to invoke service backup to Keybase
gargarplex··on GitHub Is Down
Wouldn't replacing the github hook with a git-hooks script incrementally improve the solution as it currently exists?

Then, combine that with a git-hook script that designate all non-release branches push to team's Keybase repo as well? Maybe including a custom prefix in the branch name to avoid need for conflict resolution?

gargarplex··on GitHub Is Down
It does, but it would've mirrored your latest commit before it went down.

Anyway, here's how you connect Keybase to GitHub:

https://github.com/codeforcash/github-to-keybase-mirror

Note: this was a v1, and I'm sure there are more resilient ways to do this. Critical feedback strongly encouraged (ideally along with suggestions).
