jpwright··on Inside the Incubator – Silicon Valley is satire, but feels like a documentary.
You can watch HBO on any computer/tablet/smartphone plus Roku and Apple TV using HBO Go. (I hate to sound like an advertisement here. I'm not a customer of HBO Go, but it's worth noting that they were actually one of the fastest cable TV companies to put their content online.)
jpwright··on Show HN: I built this notifying device – electronics, code, design, marketing
Looks great! Out of curiosity, why go with the hub/node approach using ZigBee for sending such a small amount of data? There are WiFi modules like TI's CC3000 (http://www.ti.com/product/cc3000) available for very low cost that would make separate hub hardware unnecessary. This is the product used in Spark Core (https://www.spark.io/), for example. I imagine there are a few different reasons why you might spring for a hub-based solution despite the higher cost, but just wondering what your thinking is.
jpwright··on Apple's Cyclone Microarchitecture Detailed
I say "can" because most Cortex-A15 design implementations don't actually run that fast. Mostly 1.6-2 GHz. Of course, we are comparing a design that's licensed out from ARM to a fixed product from Apple, so it's not a totally fair comparison.

jpwright··on Intel unveils tiny $99 MinnowBoard Max open single-board computer
The Galileo actually only emulates a subset of the Arduino libraries. The AVR libraries themselves are, for the most part, not supported. This makes many popular libraries unusable even when hardware is not an issue.
jpwright··on Apple's Cyclone Microarchitecture Detailed
Cortex A-15 can also run at nearly double the clock rate though: 2.5 GHz vs 1.4 GHz.
jpwright··on Microsoft Should Have Acquired Oculus Rift, Not Facebook
To be honest, I was in a bad mood when I wrote that and made a negative assumption about what you wrote. I'm sorry. I wish HN would let me take that one back.
jpwright··on Python Maze Generator
This is awesome, thanks for sharing! The rainbow coloring is an interesting technique for visualizing the structure of mazes.

For those interested, I wrote a similar maze generation tool in Python which includes implementations of Kruskal's algorithm, Prim's algorithm, and recursive backtracking, and can output similar images. https://github.com/jpwright/maze.py

jpwright··on Microsoft Should Have Acquired Oculus Rift, Not Facebook
> maybe even nab a few dudes

Hate to nitpick, but let's not forget about the awesome women engineers and designers out there, including at Oculus.

jpwright··on Minecraft creator says he’s canceled talks for Oculus Rift version
You're leaving out Glass, Fiber, Nest, Chromebook, and the 8 robotics companies they just acquired, among other things.
jpwright··on Minecraft creator says he’s canceled talks for Oculus Rift version
A consumer product like the Rift is an entirely different proposition with an entirely different set of challenges. The Open Compute project was essentially Facebook giving away some of their data center designs and specifications (mostly things like server racks and power management), with a few other companies joining the initiative but with none of the designs actually being used on a significant scale.

Also worth noting, the head of OCP left Facebook today. http://www.pcworld.com/article/2111680/open-compute-project-...

jpwright··on New RFS – Breakthrough Technologies
I agree. There are other incubators with domain expertise for hardware products (Bolt, Haxlr8r, Highway1, RGA), robotics (Grishin), biotech (Harlem Biospace). These places can also offer shared facilities and lab space, which is hugely important as YC's $20k investment would barely cover, for example, an electronics lab, which could also take months to set up.

This is a noble goal and I'm glad that YC wants to invest in these sort of companies, but they need to do a lot more work to convince startups of this sort that the value proposition makes sense for them.

jpwright··on Fluke owns trademark on multimeters with "contrasting yellow border"
In that case your computer is a death trap certain to cause fatal electrical shock the next time you connect your printer, flash drive, or USB nerf missile launcher. Your expensive multimeter probably won't save you in time (seriously though, do you test the grounding of your computer case every time you use it?)
jpwright··on Fluke owns trademark on multimeters with "contrasting yellow border"
That has nothing to do with the trademark issue at hand, and no one is cheering for the demise of Fluke (the post is actually very complimentary of Fluke products).

For people working with 5V circuits (e.g. Arduinos), you don't need to worry about AC power killing you or your multimeter exploding. A cheap multimeter is OK in a pinch.

jpwright··on Prominent GitHub Engineer Quits, Alleging Gender-Based Harassment
I think you are jumping to conclusions. The situation could have changed during the time she was there. It's also quite likely that she put a positive spin on things when describing GitHub publicly because it was part of her job, and she wasn't willing to go public with her accusations until it reached a certain level.
jpwright··on Prominent GitHub Engineer Quits, Alleging Gender-Based Harassment
Having a speaker series featuring women in tech is not "anti-male discrimination". Maybe it would be if there weren't 1000+ other tech conferences where the majority of speakers are men. How someone can say stuff like this in 2014 honestly baffles me.
jpwright··on Prominent GitHub Engineer Quits, Alleging Gender-Based Harassment
Yes, thank you!

It seems like every time this sort of issue comes up, a large number of men both (a) take it as a personal attack, and (b) decide that the best way to handle this attack is to counter-attack someone's character with random accusations (like that they weren't a good enough engineer to talk about harassment in the workplace).

Really, really shameful to see it unfold every time.

jpwright··on Amtrak Residency
I love the idea, and since Amtrak started the writers program after a tweet, I sent it to them on Twitter. Please RT or add more...

jpwright··on The Bay Area
> There is no institutional racism, what exists is a black latino culture that looks down upon education.

I'll bite my tongue here for what I really want to say, but dear god was this an extremely ignorant and offensive thing to say.

jpwright··on A birthday present from Broadcom
They are a UK-registered charity organization, and the Raspberry Pi is much more than just the Broadcom SoC.
jpwright··on The incredible stock-picking ability of SEC employees
But then you have conflict of interest if you're asking SEC employees to investigate companies they hold stock in. The incentive would be to not investigate or impose milder penalties.

jpwright··on Women Outnumber Men For The First Time In Berkeley’s Intro To Computer Science
I'm not inhibiting any progress by pointing out the fallacy of "more jobs = less inequality". That, by the way, is a classic example of syllogistic reasoning. We need more women to get CS jobs to increase equality, and i'm suggesting we don't need to focus on just getting them CS jobs, so I must be advocating women should have less equality.

That's not what I said, and your logic is also a poor example of syllogistic reasoning, which just refers to deducing a conclusion from two premises and is not fallacious by nature. I'm criticizing the part where you assume an indicator of progress (more women in CS courses) is unimportant or negative because of structural problems elsewhere. This is a defeatist attitude that's used over and over again to shut down social progress (we shouldn't help advance the careers of women in CS because there's sexism elsewhere!). Note that I am criticizing the logic of your post and not claiming that your singular comment has affected anyone anywhere.

...about gender diversity. Is it useful in general? Sure. Will it help you understand an algorithm's efficiency? Probably not.

So? That's not the issue at stake (although there is plenty of evidence that gender-diverse workplaces are more effective[1]).

There's a lot of different kinds of diversity we could be pushing for, like political, religious, economic, cultural, and racial diversity, but nobody's pushing for them.

People are absolutely pushing for those things as well[2,3]. I have not heard much about political or religious discrimination in the tech world. I would be curious to see any evidence on the extent of those problems.

I suspect it's less that tech workers are inherently more sensitive to the needs of women, and more likely that lonely male nerds want women to gawk at in the workplace. This could be why none of them are actually discussing the issues that cause inequality and seemingly just want to get them to work in nearby cubicles. But that might be a big leap.

That is a mightily limited assumption (which also seems to imply that none of the people fighting for gender diversity in tech companies are women!) that I strongly disagree with. Think about how the current situation came about -- male-dominated cultures emerged at tech companies because the employees were almost all men. A workforce with a more balanced gender ratio would help bring about a more welcoming and equal culture, but since the culture discourages women from joining in the first place, it's necessary to have proactive measures to improve the balance. There are other factors in play, but it's really not too much more complicated than that.

So pushing women into more tech jobs without working on the more important issues (inequality) just subjects them to more abuse, for example the misogynist kind.

This, to me, epitomizes what I find so very wrong with your attitude, which screams "keep women out for their own good, because we're too hopelessly misogynistic to create a good culture for them." Punishing women by keeping them out of tech companies isn't a recompense for misogyny, it is an expression of misogyny. Tech companies ought to actively change their cultures by recruiting and hiring more women, not give up and use their own sexism as an excuse for keeping women away.

jpwright··on Women Outnumber Men For The First Time In Berkeley’s Intro To Computer Science
No interest in debating philosophy in a HN comment thread, but saying that gender diversity has intrinsic value (and I'd argue it does, especially from a deontological/Rawlsian perspective which considers fairness an intrinsically moral good) does not negate its extrinsic value (positive social/interpersonal benefits). Either way, I don't care. My point is that the previous comment reduces the value of gender diversity in the workplace only to the degree it can solve sexism globally. Which is a textbook example of "moving the goalposts".

P.S., gender balance is "nice" for reasons that don't involve you as well. Really more about equal opportunity for women in this case, who face constant discrimination in CS, among many other fields.

jpwright··on Women Outnumber Men For The First Time In Berkeley’s Intro To Computer Science
On sites other than HN, which has nothing to do with welding?

I'm sure it's very easy to say that gender inequality in the workplace doesn't matter at all when you are not the one affected by it.

jpwright··on Women Outnumber Men For The First Time In Berkeley’s Intro To Computer Science
No one is saying that more women in CS courses will eliminate sexism everywhere. There is intrinsic value to having gender diversity in any field, and CS is one with a notable lack of it.

This is a classic example of "moving the goalposts". By claiming that incremental progress doesn't matter (or is somehow detrimental[1]) because of sexism elsewhere, you inhibit progress everywhere. By relying on strawman arguments and a false comparison to the election of Barack Obama, you implicitly frame any incremental achievement for women in CS as a failure.

[1] Referring to your, frankly, bizarre comment about a misogynist saying "you can have a computer in the kitchen". No idea what this is supposed to imply, or who exactly is saying it.

jpwright··on New Jersey slaps MIT Bitcoin hackers with subpoena
The article explains the case pretty well:

> ...the language in the subpoena reads much like the state’s computer fraud act, which carries some stiff penalties. Last year, New Jersey alleged that E-Sports Entertainment (ESEA) hijacked their [subscribers'] computing power to mine Bitcoins... the state believes Tidbit may similarly violate consumers’ rights.

According to the EFF:

> the New Jersey Division of Consumer Affairs issued a subpoena to Rubin, requesting he turn over Tidbit's past and current source code, as well as other documents and agreements with any third parties. It also issued 27 interrogatories -- formal written questions -- requesting additional documents and ordering Rubin to turn over information like the names and identities of all Bitcoin wallet addresses associated with Tidbit, a list of all websites running Tidbit's code and the name of anybody whose computer mined for Bitcoins through the use of Tidbit, although Tidbit's code was not configured to mine for Bitcoins.

jpwright··on NFL claims $600M in Super Bowl economic impact. Economists say it's closer to $0
> The NFL has revenues exceeding $4B which are nearly all "profit" (that is, revenues>opex). This cash flows through the league and then is distributed to the teams, who all of which run on essentially zero taxable profits. In other words, the revenues of the teams are the "profits" of the NFL non-profit. That is why there is no need for profits--because they distribute the cash out as 'expenditures'. The level of expednitures is aribitrary[1]...it is just set to maximize the flow of funds from the tax-exempt body with the least amount of tax.

Well, at one level the NFL mysteriously making $4B despite doing mostly organizational/marketing/legal work would seem to support the argument that the teams/games are the product. The NFL makes that money from giant TV contracts, licensing deals, and merchandise that are only popular because the sport is popular. The revenue distribution is somewhat unique -- and granted, opaque -- but not necessarily a tax-avoidance scheme. One relevant example is the MLB giving up its tax-exempt status in 2007, which had no impact on its annual taxes.

> At the lower level, the Teams are structured to run on nearly zero profits. This is why they can-not "afford" to build stadiums of pay taxes etc. This of course is also a highly-structure tax-avoidance setup, where inflated costs ("sweetheart" deals) are made with affiliate entities, which shelters the teams from paying taxes. The locations and corporate business structures of the "related entities" are likewise set up to be both opaque and tax-optimized in legal structure and jurisdicion.

If you don't consider the money they receive from the NFL, then each team runs at a huge loss. Of course, they have gigantic payrolls to their athletes and operating expenses for a stadium (this does vary by team, although the NY Jets & NY Giants funded the construction of MetLife stadium using zero public funding, for example). If you take into account the NFL's revenue distribution, then most teams make millions each year[1]. I am not sure what other tax-avoidance setups you're referring to and would be curious to read about that. Optimizing your business structure to minimize taxes doesn't seem particularly criminal.

> There is no "true sale" of the NFL non-profit's product; they take no risk in holding inventory. Their main purpose is to shield the teams from 2 things: (1) anti-trust; and (2) tax. To wit: a tax-exempt monopoly that makes no profits? Something should immediately trigger your sense of the non-obvious being present.

Of course they take risk. It's not particularly likely the NFL would go out of business anytime soon, but every investment they make carries risk. I think the one questionable aspect of the NFL's setup is that each team writes off its NFL membership dues (~$6m/year) as a business expenditure while the NFL's operating expenses (Goodell's salary, marketing, etc) are untaxed.

jpwright··on NFL claims $600M in Super Bowl economic impact. Economists say it's closer to $0
Do you have a source about how much the NFL itself spends on hotels/etc for the Super Bowl? Because I don't think that's where their claim to economic activity from the game comes from.

It also wouldn't matter very much whether the teams or the NFL itself organized the game (and part of the reason for the existence of the non-profit umbrella organization is to overcome the logistical nightmare of coordinating 32 separate entities). A condition for every Super Bowl in the past few years has been some form of sales tax relief for NFL activity. For example, New Jersey gave about $8 million in tax breaks for the game this year: http://www.nj.com/super-bowl/index.ssf/2014/02/nj_gave_nfl_8...

I also don't think it's fair to say the NFL runs the product. The teams (and the games between the teams) are the product. The NFL's tasks are: (1) Decide on a consistent set of rules, fines, etc. (2) Train and provide impartial referees. (3) Organize the Super Bowl/Pro Bowl/Draft. (4) Provide marketing/merchandise/legal stuff for the NFL in general.

Everything else (including organizing the 266 other games, the hundreds of employees for each team, and operating the stadiums) are up to the teams themselves. A "cloud services association" doesn't sound too ridiculous to me, but I don't think there's a proper analogy in the tech industry (and U.S. law recognizes this by providing some specific rules for professional sports leagues: http://en.wikipedia.org/wiki/United_States_antitrust_law#Sco...)

jpwright··on Salesforce CEO Benioff on How to Fix San Francisco
I don't believe I stated a position, and I didn't want to elaborate more without knowing the context of the previous comment. I would be pretty appalled if s/he seriously thinks Benioff is an asshole (over the one bus comment perhaps?) despite this being 95% about some totally reasonable views on philanthropy (especially relative to the stuff Perkins said)
