akjetma··on Ask HN: Can the “Who is Hiring?” post include a bit about the interview process?
Maybe it's because they aren't as focused on software as the others
akjetma··on The mobile games industry is kept afloat by less than 1% of users
> "... the report looked at over 40 free-to-play games through February 2016, analyzing the uses of more than 20 million players."

If they're looking at 40 games with 20 million players during one month, they're looking at a specific class of mobile games, not mobile games at large.

Also,

> "A new report is highlighting that risk, showing that almost half of all the revenue generated in mobile gaming comes from just 0.19 percent of users. That means the other 99.81 percent of users aren’t worth anything money-wise to the creators."

Uh, aren't they worth 'half'?

edit: anecdotally, I've probably spent about $100 in the past year on random puzzle games that probably don't end up on the top of lists. Not sure how weird/errant I am though.

akjetma··on We only hire the trendiest
I think we're starting to see the need for 'laborer' programmers. There's a lot of relatively unskilled glue/laborious coding that needs to be done. When you need someone to hammer a bunch of code out for you, you don't need an experienced and flexible software engineer as much as you need a kid with a well-trodden neural pathway that lights up when they write code in your tech stack.

I think code schools are effectively training programs for this kind of work at the companies that use them as hiring pools. I would be surprised if these companies didn't influence the schools' curricula in some way. If they aren't doing this explicitly, they should, and they should absorb some of the cost that is currently being levied against the students. Right now, we're at this weird point where students are paying for their own training at these 3rd party facilities that more or less kind of guarantee them maybe a job at this list of very specific companies but no guarantee... Something feels a bit sleazy about it. I don't know how transferrable the education you received at a code school will be once you leave the company that hired you from it.

I think the field of software engineering/programming/whatever has broadened so much that you have to have some distinguishing, domain-specific feature to get a job somewhere--the distinguishing feature of the 'trendy' programmers is usually the tech stack alignment. Maybe general knowledge of writing good, maintainable software is moot in the face of an efficiently trainable workforce, short-lived code, and a diaspora of tech stacks.

akjetma··on bar.foo
Not sure if this is what you're looking for but I've been working on a collaborative coding environment for clojurescript lately and am implementing the algorithm from this (incredibly readable) paper https://neil.fraser.name/writing/sync/
akjetma··on The Lisp Curse (2011)
I'm curious why you say that Clojure(script) is not for browsers? The only time I've really had a problem with Clojurescript is when I'm doing something that heavily interacts with an imperative browser api (like webGL). And even then I just create an interface for that part in JS.
akjetma··on State of Clojure 2015: Survey Results
'Lack' of frameworks. I always think it's kind of funny when starting a new Clojure web project, I have to explicitly insert a middleware for parsing parameter strings into a Clojure data structure, and then another middleware for transforming the string keys in that structure into keywords. There are just a bunch of things that don't magically work for you. That said, I really enjoy Clojure and appreciate/understand the high configurability.
akjetma··on Company survival does not imply job survival
I don't mean to single you out, but I just think it's bizarre that people cease to be humans when they go to work and have an ultimate duty to their organization above human dignity. Or that there is this bifurcation of work reality and 'life' reality. It really commoditizes the idea of being a good person.
akjetma··on Privilege and Inequality in Silicon Valley
A rich person can throw money at this problem or at least has the financial and temporal capacity to research it and gain an academic understanding. I know the conventional wisdom is to build something that you would use yourself, but towards the later stages of most b2b companies--especially ones that deal with enterprise customers--the customer is just as alien to anyone as poor people are to you. This is such a tiny issue compared to being poor.
akjetma··on Glamorous tech startups can be brutal places for workers
> Facebook paid $1 billion for Instagram, mainly to hire its 13 employees.

I don't usually like to nitpick, but this just seems totally incorrect.

akjetma··on Ask HN: Where are all the non-web jobs?
I think it's because it has historically been low-status work and stigma about working on the front-end persists. The majority of people I've worked with are eager to throw up their hands and commiserate with others about their lack of understanding about CSS (which, for some reason, indicates you are of higher status) rather than learning about how it works and doing a bit of memorization.

I personally have no problem doing front-end work when I have to and I think the fact that I don't drag my feet or complain about CSS has allowed me to learn it to a degree that has made it reasonable and quick to do.

Also most of the shitty parts of front-end development have been abstracted away with things like CSS vendor auto-prefixing and tools like ClojureScript and reagent. One of my favorite parts of the stack now, actually (when I can use those tools).

akjetma··on Conway's game of life computed in WebGL
Oh you're an opera user. That explains the anger. Anyways, it's fixed now!

edit: also want to clarify that I don't blindly use the user-agent string for browser detection and this was a bug in my app code. Nothing to do with my browser detection function which was working properly.

akjetma··on Conway's game of life computed in WebGL
what browser are you using? well aware of the mess that is browser detection. the function i am using is horrible voodoo cargo-culted magic: https://github.com/akjetma/akjetma.github.io/blob/master/src...

akjetma··on What photos of Facebook’s new headquarters say about work
Frank Gehry definitely doesn't have to make a name for himself. I'm surprised by how unattractive this is. Though, come to think of it, I can't picture the interior of any Frank Gehry buildings while I can see lots of exteriors.
akjetma··on Self-Driving Cars: A Coming Congestion Disaster?
I bet after awhile it would be considered bad behavior to do that.
akjetma··on Self-Driving Cars: A Coming Congestion Disaster?
Driverless cars have the unique ability to move without requiring an operator to be present. They could be allowed to park in regular spots, loading zones, tow-away spots, etc., for "free" if they provided a mechanism that enables anyone to tell it to screw off and find another place. A button on the side of the car for pedestrians and an rf receiver for people in vehicles.

I think there should probably be a tax leveraged against the owners for the increase in congestion and the reduction of the number of spots available to people without the device that tells driverless cars to scamper away, but I don't see the apocalyptic 'circling-the-block' scenario happening here. It would be cheaper for the owner to put the car into this non-imposing parking mode than the circling mode, so they would choose the former.

akjetma··on Psychedelics Could Trigger A 'Paradigm Shift' In Mental Health Care
Triggering psychosis != causing longterm mental illness. I think parties on both sides of the debate over the safety of psychedelics would agree that they can and often do trigger psychosis. And both parties probably agree, at this point, that they do not cause mental illness.
akjetma··on What people in 1900 thought the year 2000 would look like
This is tangential, but...

We had a futurist from Intel visit our small startup about two years ago for a future planning/predicting exercise. I think we were not the correct audience for these exercises though, due to the small size of our company.

What I learned from the exercise was that companies as large and influential as Intel don't have to follow market trends or predict "how things will be" because they are not subjects of some natural market--they _define_ the market.

It seemed crazy to me to have exercises planning 20+ years into the future, but Intel necessarily has to do this due to the size of the ship they're piloting.

akjetma··on Reactive Animation with SVG, ClojureScript and Om

akjetma··on Microwave Oven Diagnostics with Indian Snack Food
All these microwaves just need a more complex 'plate spinner' that actually translates the rotating plate across field lines. Kind of like a spirograph... http://i1216.photobucket.com/albums/dd371/benice_chen/hypo_h...

edit: nevermind, didn't realize they kept the 'plate spinners' on during the experiment. The rings in the appalam are artifacts from rotating an anti-node through the food. would have to do something different to get equal heating using ~two points vs. a line

akjetma··on Doctor in New York City Is Sick with Ebola
Do location-based services work in the NYC subway? I suppose you could also infer locations and transfers based on train schedules and tower handoff times upon emerging from stations. I mean, if there is a 21-day gestation period between infection time and the ability to retransmit the disease, it seems like it would be worthwhile/possible to look into.

akjetma··on “Complete Acquiesence”: How the Pontiac Aztek Happened
I'm surprised nobody has mentioned the tent-and-inflatable-mattress-and-removable-cooler-in-the-rear-center-console package. As I recall, these quirky features were simultaneously the advertised selling points and what made it unappealing, more so than its appearance. Like buying a car out of a SkyMall catalogue.

From Wikipedia[1]:

"The Aztek was able to carry within its interior a standard 4 feet (1.2 m) by 8 feet (2.4 m) sheet of plywood and was available with two rear cargo area options: a pull-out cargo tray that held up to 400 pounds (180 kg) that rolled on built-in wheels when removed from the vehicle, or a versatile cargo net system that held up to 200 pounds (91 kg) and could be configured (a claimed) 22 different ways. Options included a center console that doubled as a removable cooler and a tent/inflatable mattress package that, along with a built-in air compressor, allowed the Aztek to double as a camper. Extending this image was a seat-back mounted backpack, and a number of specialty racks for bicycles, canoes, snowboards, and other such items. An optional 10 speaker Pioneer stereo system provided a set of controls located at the rear of the vehicle for tail-gate parties as well as an unusual 2-piece tailgate with built-in cup-holders and contoured seating area for added comfort."

Most of these features are more fun than useful. Yes, I use backpacks. No, I don't need my car to have a backpack. It's like they started with a concept for a 'lifestyle' commercial with young, beautiful people having parties and campfires and looking at the stars, and then worked backwards towards a vehicle from there. Like they literally glued on symbols of vitality to a vehicle.

akjetma··on LED Inventor and Employer Settle for $8.1M (2005)
I don't think many people on HN would say "He deserves exactly what he got because he didn't negotiate for equity" or "That sucks. I'm glad I'm not a scientist!"

edit: I think I may have just been proven wrong, nevermind...

akjetma··on A New Theory of Time – Lee Smolin (2013) [video]
If a law changes, predictions made prior to the change are invalidated. Any meta-laws describing how laws change would be susceptible to this as well.

I think the idea is that, were we to have the state of everything at a moment, the laws we would use to predict the state at the next moment would be embedded within the state we had captured initially and so the prediction for the next state would have to include the state-change for the laws, for which we would need meta-laws to describe that change, which themselves would need to be embedded in the initial state, ad infinitum.

I think the only interesting idea to draw from this is that if laws change over space and time, all predictions are, at best, only probabilistic if the changes are continuous over space/time.

akjetma··on Study: Half of black males, 40% of white males arrested by age 23
I just skimmed the article and found no (re-?)definition of 'arrest'. If it's 40% for the general population and the arrest rate is a function of economic class, the rate for the lower class would have to account for the significantly smaller rate that I perceive in my middle-class peer group.

Either that or my peers are statistical outliers. I don't think there's any other form of selection going on that would prevent them from being a representative sample of their economic class, though.

The article possibly indicated a loose definition of 'arrest' here, though:

> ...arrested or taken into custody for a nontraffic offense by age 23.

For my definitions of 'arrest' and 'custody', being arrested implies being taken into custody.
