flippy_flops··on The Password Game
Amazing. I've always wanted a similar game card readers:

Remove your card before the clerk gets annoyed at you. The screen is flashes various messages like "PLEASE REMOVE YOUR CARD after the TRANSACTION IS COMPLETE". Push the card too hard and the reader falls off the table. Pull at an angle or too slow and it drags the reader.

Glad to hear there's a roadmap. In my PAAS thrashing I've got quite a few notes:

- no wildcard subdomain ssl - poor metrics, nothing per instance - poor dyno granularity - (jumps from 2.5GB RAM to 14, no cpu/storage control) - no transparency on what each dyno actually is - external postgres replication disabled (deal breaker) - no first class postgres metrics and access logs/alerts (kibana recommended, but not great) - no external postgres backups (e.g. S3) - no deletion locks on dynos and add-ons, esp databases!!! - no warning when add-ons like databases are being deleted as a result of apps being deleted - deleting an add-on also irreversibly deletes all replicas and backups - painfully inconsistent naming for databases through their connection str env - dyno types for build processes use Perf-M? Not configurable - No lambda or github action style computing - No scheduled scaling - Unable to choose aws-us regions - Hard 30s timeout limit - Limited to 1 api key per user. No labels, configurable permissions, usage logging - no http/2 - frustrating enterprise offering. massive over-sell, near zero value

Strongly disagree with this take and especially the tone.

"Is two years enough experience to create a curriculum?" is a good discussion prompt but it's hardly a silver bullet for dismissing the project. A counter argument is that being new to the field gives the OP a fresh perspective.

OP never claimed to be an expert and there is nothing disrespectful in this post. It's too bad it's the top comment. Best of luck to OP on pursuing a new way of engaging students.

I hate what Salesforce has done to Heroku but after a year of running our saas on aws, render, and fly - here I am, back on Heroku. It sucks, but slightly less than the alternatives.

Fly has potential, but they've changed/grown so much that most docs are out of date, everything is buggy, support is not very responsive, and their security posture leaves a lot to be desired. Not a fun place to be production issues pop up.

flippy_flops··on Google I/O 2023
5-10 years ago I’d agree they were very good. My suspicion is that the base spam filter is not very good but it trains on your email history and becomes better. So my “newer” gmail accounts have very poor filtering.

Like I get all caps subject lines with spammy content that my grandmother would recognize as spam, but it blocks some personally written emails from other gmail accounts.

I’ll be more interested in Google’s ML when they use it as a competent spam filter for Gmail. As it stands the false positives and false negatives are baffling. Maybe it’s unfair but to me that directly reflects their ML abilities

flippy_flops··on Ask HN: Buying a Premium Domain
If it’s listed on a marketplace, find their direct contact info and they’ll likely take a lower number since there are no fees.

If you’re emailing them, word your message to make it clear you’re not a bot. Persistence over time is often necessary.

One domain we actually wrote letters. The company didn’t even know they owned the domain. (They got it through an acquisition)

If their number is insanely high, see if they’ll consider a trade. That’s worked several times because they overvalue both domains.

Use some type of escrow service. We normally split the fees.

flippy_flops··on Ask HN: Next big thing in Computer Science or tech according to you?
IMHO Apple’s AR/VR device will be another incremental but major milestone for mainstream VR.

Stable Diffusion is already making waves in digital art. I expect more specialized models fairly soon.

Free data and services we used to take for granted like YouTube, farming software, and car seat heaters are becoming forcefully monetized. Will we someday refer to these as the good old days when search engines were “free”?

flippy_flops··on Is engineering management bullshit?
The best manager I've had described his job as "working for developers". Like a shared assistant that acts as the communication point for stakeholders, gladhands needy customers, completes rfps/security questionnaires/other paperwork, finds talent, etc. Seems like any other position - a great manager is priceless / a bad one is pernicious

flippy_flops··on Ask HN: What is the highest consulting rate that you have come across, in tech?
Several jobs ago we had an external hard drive that was plugged in under an IT guys desk. Despite having a high end server room 50 feet away, all of our companies main financial/etc files were stored exclusively on that hard drive. It crashed and brought the $80M company to its knees.

Basically the shared drive was much easier to use so everyone ended up using it over time.

Ended up paying a data recovery group $5k/hr to recover what they could.

flippy_flops··on Ask HN: What API would you pay for?
a dark sky clone

Apple bought Dark Sky and closed the api for new devs. Supposedly they'll shut down the api next year for existing customers. If that happens, there are a bunch of sites/apps that would love to swap out their connection string to a similar service.

flippy_flops··on Ask HN: Have you ever tried two PC development?
I’ve developed on two computers for about 6 years - an iMac at my office and MacBook Air for home and travel. All my projects are in a Dropbox folder but I also use Git. It works really well.

The biggest issues are when Dropbox detects conflicts and spits out conflict files. I wish I could turn that off. Checking out a different branch can be noisy because Dropbox will sync all the “changes” files.

The only major problem I’ve had is Dropbox bogs down with 500k+ files - even if they are very small. NPM will put you there fast.

flippy_flops··on How to brainstorm great business ideas
This is good advice, but I think the fundamental issue for many people is that they are looking for a formula to supplement their own brain.

In reality there are many classes of successful businesses. It’s hard to explain the success of a restaurant franchise and of flappy bird in the same formula except to over generalize it as, “decent idea with decent execution and decent timing in front of a decent audience.”

I do think posts like this are very helpful at eliminating dead end habits. I know I’m guilty of searching for a lock.
