I'm a software engineer based in the North Bay. I'm actively looking for remote work opportunities, whether short-term or long-term.

wtracy··on Landlord Tech Watch – What Is Landlord Tech?
I really wish this page did a better job explaining why "landlord tech" is problematic. It doesn't really go deeper than mentioning erosion of privacy (without concretely explaining how that happens) and making vague statements about racial inequity and evictions.

As it is now, it reads like an appeal to the general resentment of "big tech" and of landlords ("if it makes their jobs more efficient, it must be bad!") than an actual exploration of the problem.

I don't doubt that the articles linked at the end describe some horrifying real problems, but making the audience sift through a list of links is not an effective way of motivating people.

wtracy··on Zoom towns and the new housing market for the two Americas
This.

The FAANG crowd is used to pulling down $100k-$150k. Developer jobs that are advertised as remote from day one tend to be closer to $50k-$70k.

(These numbers are based on a combination of rumors and job board postings, so no, I don't have a source to cite.)

wtracy··on PayPal is currently blocking all transactions containing the word “tardigrade”
They have a whole department called "risk management" that is responsible for combatting fraud. (I worked for PayPal under that department in a past life.)

I'm sure there's a "security team" somewhere that responds to attempts to directly breach PayPal's infrastructure, though I never interacted with them. (Paypal has quite a bit of on-campus physical security, and I did interact with them almost every week.)

Circling back to the discussion at hand: PayPal probably doesn't have any digital/financial security staff at their call centers (why would they?) so as far as the call center reps are concerned, there is no "security team".

wtracy··on Tech firms face growing resentment of parent employees during Covid-19
> pretending nothing is wrong.

And there's out problem. The covid situation in the US is a trainwreck because we can't get everyone to follow basic hygiene guidelines and practice social distancing.

We could have basically whooped this thing months ago if people weren't violently resisting face masks and similar measures.

Actual mechanical pumping.

> It could only walk on flat ground. It was supposed to be able to cross a ditch, but that was manual.

Well, now I'm wondering what they needed eleven onboard minicomputers for. How much route planning intelligence do you really need if you're operating over identical terrain every time?

wtracy··on FBI examined Google records to see if anyone had knowledge of Guccifer persona
"Oh, your new office building looks nice. Did your construction firm get all the necessary permits? Are you sure? All of them? Oh, and I see you have a lot of new employees. A lot of them. I bet it would tie up your HR department for quite a while if the INS came by and requested documentation that all those employees are authorized to work in the US, wouldn't it?

"Anyway, I've come to ask whether you could do a favor for us."

Can you offer any advice or resources on what to ask or watch out for in this area?

wtracy··on Ask HN: What non-obvious tech/market may take off in the next few years?
This is what genetic recombination has made possible in tropical fish in just the last ten years:

https://www.glofish.com/

I don't doubt we will see CRISPR and friends applied to ornamental plants the way they are already applied to food crops.

wtracy··on Ask HN: What non-obvious tech/market may take off in the next few years?
IDK, high-speed rail doesn't seem to be taking off outside of Europe and a handful of Asian countries.

That leaves most of Asia outside India/China/Korea/Japan, and pretty much all of Australia/Oceania, Africa, the Middle East, and the entire New World.

I would love to see high-speed rail take over the world, but there's a lot of sparsely-populated places out there, and it makes sense to investigate technologies to support them.

wtracy··on Ask HN: What non-obvious tech/market may take off in the next few years?
In my mind, "the cloud" came into existence when it became practical to rent servers (virtual or physical) by the hour, rather than by the month.

It's one of those things where a difference in degree in implementation terms (leasing in smaller time increments) allowed a difference in kind in usage terms (on-demand server allocation over advance provisioning).

wtracy··on The software industry is going through the “disposable plastic” crisis
I think GP was complaining about "most apps that are built with Electron", not Electron itself.

The complaint supplies equally well to most mobile apps today.

I have a tablet I'm scared to mess with because it has a copy of the Android port of Frozen Synapse, and the game has since disappeared from the Play store.

I paid real money for that game, to boot.

wtracy··on Who to ignore – bullshit filters
I really feel like #3 really means "Do they take my field of expertise seriously?"

The author's field of expertise is software, therefore only people who take software seriously are worth listening to.

wtracy··on Who to ignore – bullshit filters
I can see this one backfiring if someone's livelihood depends on their past predictions being correct. Now they have a strong incentive to double down on those predictions, and dismiss contradictory evidence.

Anyone whose livelihood depends on providing a solution to Problem X will assure you that X will continue to be a problem well into the future. This is visible everywhere in both for-profit and non-profit organizations.

I don't doubt that the people who run MADD sincerely believe that drunk driving was a pressing problem when they joined. But are they ever really going to tell you that drunk driving has been successfully addressed and isn't a problem anymore? Or that they were wrong after all, and it never was a problem? (I just picked MADD randomly. Substitute the mission-driven organization of your choice.)

Snowpiercer is the inverse: People have to stay in sunlight to survive, so they build a nuclear-powered train that runs around the world's equator.
wtracy··on Rideshare operations are being suspended in California
Spitballing here:

Option 1: Deny any attempts to "clock in" whenever the number of drivers waiting in a region exceeds a certain density.

Option 2: Your shift starts when you pick up a passenger, and ends when you drop them off. (I have no idea whether this actually meets the state's requirements. I do suspect that there exists an equally clever solution that will work.)

Uber and friends built their entire businesses in working around existing laws. I'm sure they can figure out how to navigate the new laws.

wtracy··on Rideshare operations are being suspended in California
I've never seen a rideshare "pool" multiple riders. I'm sure it does happen, but it seems pretty rare from where I am.
wtracy··on University Endowment Sued for Under performing the S&P 500
Thank you. The fund manager's comments suggesting that the index funds are unnecessarily risky make sense now.

The original article kind of made it sound like the fund invested in stocks and still managed to underperform the stock market. If you draw that assumption, it makes this sound like an open-and-shut case of negligence.

wtracy··on Can't you just right click?
From Apple's documentation:

> There isn’t a specific identity requirement for this signature: a simple ad-hoc signature issued locally is sufficient, which includes signatures which are now generated automatically by the linker. This new behavior doesn’t change the long-established policy that our users and developers can run arbitrary code on their Macs

So, the sky isn't falling yet, but it is reasonable to be concerned.

wtracy··on If founders treated their investors the same way they treated their employees
> They might be the only shop in town offering a Haskell job

I learned this the hard way: Do not let the technology stack be the deciding factor in which job you take.

Skipping the Cobol job is reasonable. Picking the only Haskell job because it is the only Haskell job isn't.

wtracy··on If founders treated their investors the same way they treated their employees
In these situations, I think it's meaningful to differentiate between "investors" and "speculators".

If you're going to pitch an AWS service as "offline", then pitch Glacier.
wtracy··on Canon's cloud platform has lost users' files and can't restore them
By "raw" I think GP meant the files originally provided by the users, not actual RAW files.
wtracy··on Dependency
Both projects are moving fairly fast, and regularly adding new features that are not shared.

The last time I made heavy use of ImageMagick/GraphicsMagick, I was suprised how often I would find a feature present in one and not the other (often things like drawing gradients).

And it's not like one has a superset of the other's features: I once painted myself into a corner and created a project that depended on both ImageMagick and GraphicsMagick.

wtracy··on Dependency
Netpbm seems to have terrible support for modern image formats. Unless I'm missing something, I can't imagine using it to handle user-supplied images.

> Are you threatening people’s jobs?

Yes.

> Do you think you can reliably get away with that?

Robber barons did reliably get away with it throughout the nineteenth century. That's the whole reason that you don't get to take a copy of your ballot home today.

> It’s totally unrealistic

Well, somebody forgot to tell reality.

wtracy··on A guide to learning algorithms through LeetCode
FWIW, I've found that companies outside the valley, particularly those that don't see software as their primary product, are more interested in work samples than puzzle solutions.

Try broadening your search to things like aerospace and medical technology companies.

> Blackmail doesn’t scale.

If elections in my district are historically won by a 10-20% margin, and my corporation directly employs 20% of the people in the district, then I think I could make blackmail scale just fine.
