telchar··on A Million-Dollar Cancer Treatment: Who Will Pay?
Well it's a concept, but it's applied very hypocritically. It seems mostly about social status. "All lives matter more than anything else but some lives don't matter very much at all" would be more accurate. Some people get millions of dollars in treatment (they're wealthy or have employment with a company with good insurance) while others die slowly for lack of a few bucks for a prescription (they already lost their jobs due to previous illness, mental illness or addiction, or just got unlucky with timing).

Politicians in certain states and in the federal government are doing their best to make sure people without jobs can't get help with affording treatment as well. Frankly to claim that we in the US care more about lives than those in other developed nations with rational disbursement of healthcare funding is just wrong.

Sorry if you weren't implying that, but I think you were.

telchar··on Relative's DNA from genealogy websites cracked East Area Rapist case
Actually all of that, together, make him a suspect. Any of it might not, but all of it does. Each piece of evidence reduces the likelihood of coincidence. Now that they have the suspect in custody they should be able to do a one-on-one test with the old DNA and confirm their suspicions to a reasonable degree of certainty, assuming they do their jobs well.

But yes, good luck explaining that math to a jury.

telchar··on VC Tim Draper has revived his proposal to carve California into smaller parts
I don't know, but I can only assume. Who else would want to split up California and has a thing for busting unions?
telchar··on Google’s new Chat service shows contempt for Android users’ privacy
They're the oil-rich nation of companies. They can afford vanity projects and woeful mismanagement as long as that sweet sweet advertising money keeps coming in. The sectors of the company that keep that running are run well, but side projects like this seem to come and go with little rhyme or reason as far as I can tell. Much like how the militaries of some countries are well-run and competent (and control the oil) while the rest of the government is a clown show.
telchar··on Why people have trouble reading neutral faces
I know you're joking, but I think the former has to do more with facial features/structure and the latter is more a case of demeanor (not that it actually involves attempts to cause death through eye contact, just that it's different and unsettling to some). Probably the overlap is when the death glare is more noticeable.
telchar··on Instagram launches “Data Download” tool to let you leave
You're making this argument as if the whole FB/Cambridge Analytica thing hadn't happened. There is power in these systems and when they're affecting our governmental structures we have a vested interest in regulating them.

This is perfectly analogous to the real world where e.g. pollution has tangible negative externalities. It will always be the case that when responsive governments exist, and a thing comes into existence that people perceive as a threat, people will leverage the government to mitigate that threat.

If your home were perched on a cliff above a school playground, to use a contrived example, the townspeople would have a keen interest in the integrity of your home including the kitchen and bathroom.

We could also join together Kansas, Nebraska, Oklahoma and maybe a few other plains states into a single state. They always vote together and most people can't tell them apart anyway, plus there's the efficiencies of reducing redundant government functions to think about. And the naked partisan interest is just gravy.
telchar··on VC Tim Draper has revived his proposal to carve California into smaller parts
The senate is two votes per state... though the ratio works out the same. Clearly the new states would vote more heavily Republican on average than California currently does, else he wouldn't be proposing this. I suspect the big win (for him) electorally would be peeling off votes in the Electoral College. The article mentions union-busting as another motive, which squares with the right-wing motivation.
telchar··on Show HN: Intuitive Linear Algebra and 3D Geometry
I appreciate any effort to make mathematical explanations more intuitive. A couple of thoughts:

1. There are a few grammatical errors (missing word, missing comma) that are forgivable but I find that any imprecision in language is a big detriment for a student trying to understand an explanation. I tend to get hung up on those since, not knowing the material, I can't resolve ambiguities with context. Since subtleties are important in math it would be worthwhile to go over the explanations again with a fine-toothed comb to ensure there are no typos or amphiboly.

2. The visuals aren't always clear. For example, volumes don't show edges so it's hard to make out that you're seeing a volume rather than an irregular area (and which volume you're seeing). Also I think a caption to each image could be useful, to describe how the shape demonstrates the concept. Something like "this visual represents a shear transformation of the matrix described above", just to be really explicit and clear.

Would you care to share the server auction site? I've thought about doing something like that.

An extremely left leaning organization run by a huge multinational for-profit conglomerate? Perhaps you should look up characteristics of far left organizations. I don't think you know what that term means.
telchar··on Finland is scrapping plans to extend its basic income project
Of course that's not just a basic income, that's a full cushy income. A better example with be Alaska which uses ok revenues to give a subsidy to residents of the state.
telchar··on California Opens Investigation into Tesla Workplace Conditions
BMW's market cap exceeds GM's today, so that all seems to check out. Tesla's valuation assumed high future value; their stock could stay stagnant as they grow to BMW production numbers and they'd be doing great. Just growing into their shoes.
telchar··on The IRS Really Needs Some New Computers
You have that backward, underfunding the IRS to cause dysfunction is the strategy that is used to gin up support for simple easily-gameable tax schemes like "flat tax".
telchar··on OLPC’s $100 laptop was going to change the world
Your mention of the poor touchpad accuracy really brought the frustration back to me. That may have been the single biggest issue that drove me to stop using mine. It's a shame, the XO had so much potential, but the problems you mention doomed it. Much like the Aptera electric car around the same time (off topic, but that was a similarly bold product that ultimately failed by a death of 1000 bad design decisions despite a lot of good ones).
telchar··on OLPC’s $100 laptop was going to change the world
I was very bummed that h g1g1 xo didn't come with a pullcord generator. I thought it was a great idea.
telchar··on OLPC’s $100 laptop was going to change the world
Yep, I had both an XO and an EEE in that order. The look on the university help desk tech's face when I brought the XO (running puppy Linux at the time) in to get a network cert install was fun. I recall moving from the XO to the EEE mainly because the latter was faster and more pleasant to type on. There were few other competing net books at the time.
telchar··on You Can’t Do Data Science in a GUI
That's a good point. In a block of 10,000 cells that should all have the same formula (offset by 1, say) how do you know that they all actually have that same formula? I'm not aware of a way to check that that doesn't involve writing custom VBA.
telchar··on You Can’t Do Data Science in a GUI
I have used Knime for a few months, enough to get comfortable with it, and while some of what you say is true I have to disagree about it standing up to command line tools. Especially after having tried to go through some code written by others in it.

The main problem I have with it is in many cases the upstream data has to be available to a node in order to be allowed to open the node up and see the configuration. This has resulted in my spending a day or two updating and tweaking database queries on an old connection and fixing the resulting configuration errors just to get to one node and read the configuration. In this case I didn't care about the data itself, I just needed the config of that one node.

This would not have been necessary with a text-based tool, where I could just scroll down and read. Knime can be a powerful tool but for sharing work I think it's unnecessarily painful.

telchar··on H&R Block and Intuit Lobbying Against Simpler Tax Filing (2017)
That's an interesting point you bring up. By holding their cards to their chest, the IRS ensures there is significant risk in tax evasion. If they were to send out a pre-prepared return, any mistake the IRS made there in a filer's favor would be much less likely to be caught as long as the filer went along with it. By not revealing in advance what they know they incentivize the filer to be honest and thorough.
telchar··on Why Entrepreneurs Start Companies Rather Than Join Them
That's why replacing corporate income tax with personal income tax, which many here advocate, won't work. However that issue can be mitigated by taxing companies on the value of perks
telchar··on Portugal electricity generation temporarily reaches 100% renewable
I think you may still be a little confused. Power density is the rate at which energy can be added to or drawn from the the cell per unit mass. So faster charging and discharging means high power density. Energy density is the total amount of energy that can be stored per unit mass. Supercapacitors are typically higher in power density and lower in energy density than batteries[1].

You're right that it makes sense to put supercapacitors in front of the battery banks for the reasons you said.

telchar··on Portugal electricity generation temporarily reaches 100% renewable
If you're going to be mentioning this again in the future please correct your usage of power/energy density. Power density is measured in W/kg, energy density is measured in Wh/kg. Supercapacitors tend to excel in the former but be poor in the latter. You mentioned power density but used units for energy density. This happens so often in media that I feel the need to correct it even in a comment.
telchar··on Breaches of Unsecured Protected Health Information
I wonder how many of these are encrypted systems. I see a lot of "theft" and "loss" on that list. I know if I were to lose a system that had PHI on it I would be required to report the breach even if the system had full disk encryption. I'd bet many or most of these are similar.
telchar··on Facebook was in talks with hospitals about a proposal to share data
The situation regarding Facebook and privacy is very much unresolved. How can you call it a dead horse? Facebook is very much a large, living, dangerous horse. I think we shouldn't let up until the horse changes its spots or dies.
telchar··on Berkeley offers its data science course online for free
As someone in data science this isn't a trend I particularly like. I suppose to some extent these jobs can be filtered out by requiring a salary that they're not willing to pay for that work.

You chose a funny example. A lawyer can make captain in the military just by signing on the dotted line, same with a doctor.
telchar··on Tesla crash victim had complained about auto-pilot in same location
That's entirely speculation at this point. Tesla are the only ones who could confirm or deny that and it's possible that they will never be able to determine it depending on the condition of the computer hard ware.
telchar··on Tesla crash victim had complained about auto-pilot in same location
It's too early to draw that conclusion. Note that the claims in the article are coming from the family and haven't been corroborated by Tesla yet. It's possible they are incorrect about aspects of the story they're telling for various reasons.
telchar··on U.S. To Seek Social Media Details from All Visa Applicants
The huge growth of fake news/misinformation and punditry-as-news in the last couple years, which really has been on the rise for decades, seems analogous to trolling. It's very difficult to have a good discussion with nuance and mutual respect when trolls are involved in a thread. Likewise it seems the general public conversation is being disrupted and dumbed down. I see the same effect you do and I think on at least some parts it's intentional.
