ranman··on Rent going up? One company’s algorithm could be why
You can't reasonably compare a housing vacancy tax with a hyperbolic straw man argument of a theater. It's not a similar phenomena at all, because it doesn't happen.
ranman··on Google loses EU appeal and is fined a record $4B
EU regulations + individual country restrictions are written in a way that's allergic to running a profitable business (with a few notable exceptions).
ranman··on Shopify lets staff decide cash-stock pay mix as shares dive
Do you know if this creates significant administrative overhead?
ranman··on WebKit on GitHub
FWIW not all of those outages were the core git/web product. A lot of those were GitHub actions or other associated functionality... but yeah it goes down disturbingly often given how much we all depend on it.
ranman··on After years of setbacks, NASA’s SLS moon rocket is ready to fly
> NASA is not incompetent or corrupt and neither are its contractors.

Corruption is one thing I don't feel qualified to comment on but having worked for both NASA and for a few contractors... yes they're absolutely incompetent.

They have expertise in small pockets but the overall organization is surrounded by giant cushions of bloat. NASA could drop ~50% of their staff and nothing would materially change. ULA could drop ~20% of their staff and nothing would materially change.

ranman··on CEO Shadow Program
FWIW there's a lot of politics in this process. Existing talent in SEA is far more likely to get selected for these roles rather than offering global top talent a 2 year stint in SEA to see if it fits. The people that receive these TA positions are purposefully selected and groomed for future exec roles. The program does have a good track record of success but they made a few bad bets as well.
ranman··on How I write React after 8 years
> don't use (almost) any libraries

Proceeds to recommend several libraries.

Unfortunately the opinions in this post are an odd mix of correct, incorrect, or irrelevant.

ranman··on Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid
Yeah so if you can math.round or math.floor them a bit the paths are a lot cleaner - if you're dynamically creating them anyway though then I don't know that it gains you much performance. It might gain some performance on render for larger maps? Not sure.

Didn't get a chance to look at your source.

ranman··on Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid
Why are the SVG tiles specified to 599.99999999 instead of 600 or something? I think a SVGO optimizations run would reduce the size of the assets a tad.
ranman··on Ask HN: What are some cool but obscure data structures you know about?
t-digest is used by AWS X-ray to render their charts
ranman··on FedEx to close data centers, retire mainframes
Why would one have to hire a whole new cadre of technical talent? Wouldn't it just be taking existing talent and/or ops teams and having them work with the autoscaling APIs as opposed to working with the data center teams. If the skillsets don't match then you can either train existing talent or, yes, hire new folks.

I agree the occasional phone call removed from your workflow isn't reason enough to justify a giant cloud migration... but it is one of many reasons.

ranman··on Paige Thompson convicted over data theft from AWS user accounts
1) I think your opinion here is 3-4 years out of date. Check out the modern interfaces.

2) at a bank's scale it should not be using the console for anything in production.

ranman··on Apple’s macOS Ventura – New Security Changes
nodejs has joined the conversation
ranman··on Ford CEO says EVs will be sold 100% online with nonnegotiable price
Wait didn't they lobby against this like... 10 years ago?
ranman··on Graviton 3: First Impressions
One key call out re: power from that paper - "Most OpEx cost is for provisioning power and not for electricity use [2], so saving power already provisioned for doesn’t improve TCO as much as one might hope."
ranman··on Graviton 3: First Impressions
I'd peg it closer to 75%. There's some significant opex on the endpoint connectivity side as well. That's why a lot of these providers are buying stakes in some of the transoceanic cable projects (and some terrestrial ones as well). Or they're agreeing not to charge each other (kind of sort of- see open bandwidth alliance).
ranman··on We lost 54k GitHub stars
1) probably not the desired experience

2) probably part of the currently required setup on their database side (triggers)

Features tend to evolve evolutionarily and certain data patterns are hard to invent around for security/privacy constraints. So err on the side of deleting rather than potential privacy/security bug.

Definitely fixable with some decent investigation, coding, etc. - but hard to prioritize.

ranman··on Elon Musk to join Twitter’s board of directors
I worked at SpaceX. I was well compensated. It was a good time.
ranman··on Elon Musk to join Twitter’s board of directors
because the stock grew like crazy and everyone got rich?
ranman··on What's my place in the world population?
Cool idea... not the best architecture. Tell me you don't know how to optimize webapps without telling me you don't know how to optimize webapps. Anyway just poking fun, hope the owner can figure out how to make things work.
ranman··on AWS's us-east-1 region is experiencing issues
STS will let you use regional endpoints now, right?
ranman··on Ask HN: Who wants to be hired? (December 2021)

ranman··on Ask HN: I’d like to hire a personal/executive assistant – any tips or advice?
Whoever you go with I'd advise against going with someone who is an existing friend or family member. It creates a hierarchical relationship where there should only be an adjacency.

The least reliable cloud service provider … relative to what?

A comparison of historical downtime amongst DNS and CDN providers shows this to be an illogical consideration.

I’ve been using cloudflare for years at both small and very large scales.

They have had outages yes, but again, relative to the rest of the cloud providers they’re doing just fine.

ranman··on Nerds don't respond to marketing; try technical documentation instead
Developers are consumers like everyone else and they absolutely respond to marketing. Large cloud providers employee entire teams of developer marketing staff. Just like every other kind of marketing it’s about tailoring your message to your target market.
ranman··on Blue Origin first human flight
Blue Origin technically started before SpaceX and has an increasing delta in accomplishments... They're easily a decade plus behind and SpaceX doesn't seem to be slowing down.

Bezos is smart and talented... but it's hard to overcome a lead like that.

ranman··on Amazon.com product pages are down
This is incorrect.

ranman··on Ask HN: Most Useful Cloud Certifications ( Azure, AWS, GCE, ... )
I haven’t seen the Azure or GCP certs as a strong hiring signal.

The AWS associate certs are similarly low signal, anyone with some skill at multiple choice can pass those.

The AWS professional certs and AWS specialty certs (big data, ml, networking) are all a solid hiring signal, to me. You can’t pass those exams without handson experience. Memorization isn’t enough. The networking cert in particular has a lot of content that most struggle with in the cloud.

ranman··on Launch HN: Explo (YC W20) – Customer-facing dashboards and reports
I’m excited about the possibility here but as a dev I’m waiting for that self-serve functionality. I would have paid a modest fee for a month or so to try it out and maybe converted to a prod customer if it met my needs.

There was a great thread recently on developer marketing here: https://twitter.com/nickwritesit/status/1402318187299934212?...

You should post again here and on producthunt when there’s self-serve signup and live demos.

The videos look good!
