danjayh··on NASA proposes new propulsion to cut Mars voyage to 3 days
As much as I love the idea, it is fairly impractical for the reasons that other commentors have noted. Call me greedy, but within the constraints of a balanced budget, I would like to see an increased portion dedicated to science (be it a 'cancer moonshot' or an actual marsshot) vs social programs ... maybe we could find some real solutions to these issues. In my own life I have a tendency to skimp on the 'now' in the name of investing in the future, so this is probably just me applying my own financial philosophies at a larger scale.

I would actually strongly recommend that he not list google on his resume. Unless Google has a policy against sharing whether a candidate was fired or left on good terms, it might not be beneficial for him to have potential employers calling Google for prior employment verification.

Also, for a throwaway account, you're pretty active here on HN :).

danjayh··on Samsung’s Galaxy S7 and S7 Edge
Being off contract, you save the most money by the fact that you aren't forced to continually upgrade your phone to get your subsidy. I'm on a ~$25 USD/month plan with unlimited talk/text + 2.5GB LTE, and I typically keep my phones ~3 years. Having said that, as you stated, even if I needed to have new phones every year, it'd still be cheaper than a contract :).
danjayh··on Samsung’s Galaxy S7 and S7 Edge
Your battery life is great now, but what about 3 years from now? The current ~2 year phone refresh cycle should not last forever, and I think that both the S7 and the nexus have it wrong when it comes to batteries. Even at a gentle 50% Depth of Discharge, a typical li-ion is at only 70% capacity after ~1200 cycles. Bump that to near 100% DoD, and you're at 70% after only 300-500 cycles. Sealed-in batteries in a phone are, IMHO, even a bigger deal than the lack of expandable storage.

danjayh··on Yahoo Said to Start Approaching Possible Bidders Soon As Monday
Marissa Mayer's been at the top for 2012, and really is responsible for the direction that Yahoo has taken in the past four years. I have to wonder -- will Yahoo's sale (and inevitable downsizing) play out worse for her, or the people who were merely following her direction?
danjayh··on Yahoo Said to Start Approaching Possible Bidders Soon As Monday
Even though Alibaba is Chinese owned, and based in a country whose attitude toward free speech is not something I'd like to spread, somehow I'm more comfortable with them as a suitor for Yahoo than I am with Comcast or Verizon (shudder).
danjayh··on Reverse engineering Android from binary to source
This article is fascinating, and having done board bringup work, I understand the challenges that the author faced. He did absolutely top-notch work. Getting a board that does nothing, has no debugger, no output of any kind going is really hard. However, to me the most important quote in the story is this:

> As per the GPL (under which the Linux kernel is licensed), the manufacturer had to have provided a written offer of sources. Needless to say that a random chinese company (SmartQ, currently owned by Huami) does not care even a little about this sort of thing. I checked theit site every which way I could, and found no sources. Emaling them produced no reply, of course. Of course, why would it? I tried to find some people on LinkedIn who might help, but I was told in no uncertain terms to go away.

With increasing amounts of SW development moving to low-cost countries, this sort of attitude may well eventually destroy the availability of the 'free' software that these manufacturers rely on (besides hurting the GPL + homebrew firmware communities).

danjayh··on The Unsuitability of English (2015)
As a native English speaker who has never learned another language beyond high school Spanish, I often feel sympathy for the plight of those who are forced to learn English later in life. I see many native English speakers with a tenuous grasp on the language, and from that and anecdotal evidence I know that it's a hard language. I remember how difficult Spanish, ostensibly an 'easy' language, was for me to learn. I'm glad I'm not in a position where I need to learn English late in life, and I'm sorry for what we've done to you, world :).
danjayh··on LG G5 modular phone: Hi-Fi DAC, battery slide out, connection interface
I realized the irony of complaining about Engadget going inappropriately off-topic and then doing so myself, and edited that out. Trying my best to stay on the rails :). I do stand by my opinion that even their tech-focused articles are horrible these days, including this one. To anybody reading this now -- klausa is not just writing crazy replies, I did previously have a blurb about a graphically explicit non-tech Engadget article in the parent comment.
danjayh··on LG G5 modular phone: Hi-Fi DAC, battery slide out, connection interface
Interesting phone, horrible article. Typical of the modern Engadget, the article is light on facts and heavy on superlatives. For instance, I had to head over to some random Android website (androidHeadlines) to find out that yes, it does have Micro SD card support, and that it has 32GB of built-in storage (pathetic, Engadget). I do really like the idea of extensive expandability, but I wish it could be standardized somehow (admittedly difficult in a mobile form factor). I think this would encourage the creation of interesting devices by interesting startups, which is something that would probably get everybody here excited.

If you want a decent article by a respectable pub, check out the Ars version (linked below). It has all of the technical info that Engadget missed, minus the comments on how 'fantastic' the device feels.

100% agree. It's incomplete & disorganized, a very sad state of affairs. They need to assign someone to go through and fix it.
danjayh··on Evidence that fish have feelings
I can tell you with great certainty that the cat presently sitting in my lap has feelings. When she's angry, she turns into a total bitch and knows just how to press my wife's buttons :) Example - after getting upset about being put on a diet a while back, she relieved herself in my wife's shoes. My wife handles the feeding.

We have 4 cats, two horses, a goat, and a dog. All exhibit behavior that is inexplicable without emotion. I realize that all of these creatures are pretty close to one another in terms of classification, but it wouldn't surprise me a bit if these behaviors existed in creatures more distantly related to our cadre of quadrupeds.

danjayh··on ARM Mbed IoT Device Platform
Every time I see Linux used in a project like this, it feels like hitting a trim nail with a sledgehammer. I hadn't seen mbed OS prior to this article, and after perusing the documentation and checking license (apache), I have to say I'm pretty stoked about it. mbed os seems to be far better suited for tiny / lightweight devices than Linux ... anybody used it in an actual project? Have any thoughts to share?
danjayh··on ARM Mbed IoT Device Platform
I took a look at the mbed os socket API, and it supports opening a socket in 'listen' mode. With a few lines of code, you should be able to build this into a basic server. What functionality is missing that would be required for the use cases you mention?

danjayh··on Secondary shops flooded with unicorn sellers
Agreed. I've done that in the past and done quite well, but when I got married I dumped all my non-retirement portfolio. 6% guaranteed return paying down student debt (plus getting rid of payments, which hadn't been something I'd dealt with before) beats playing games in the stock market for me. Plus, I like to make my bets while the market is already on the way down ... during the last recession I started buying on the way down (after prices had already dropped quite a way), and stopped when the market got back to where I'd started, which worked out quite well. I did most of this in my 401k and IRAs (to the limits allowed by the contribution rules), so I also scored tax benefits :). Biggest non-retirement bet was buying a house in early 2011, which also turned out to be a decent thing to have done in my market ... although I think that there is a significant possibility that the gains in value due to the market will be wiped out in the future.

Assuming continuous inflation, the absolute price of housing will always increase. However, affordability decreases as the ratio of housing price : income increases. There is a limit above which a vast swath of the population can't afford houses, and somewhere just beneath that limit lies another at which the price of housing collapses. That's assuming that the effect of speculation never becomes large enough to outweigh a collapse of real demand.

EDIT: I am specifically referring to the "Price to Income" chart in my comment below, not the one that shows up by default. Sorry for the confusion.

--

Uncheck everything but the 'US' graph. Different data sources give different ratios, but they all show that it's still well above historical norms & headed up. Some data sources say that it's already approximately back to where it was in the peak (see a link further down, that chart is up-to-date), others like this one only show it ~1/2 way there (note tat this chart is two years out of date), but either way we're above what has been stable in the past.

danjayh··on Secondary shops flooded with unicorn sellers
I was referring specifically to the cheap debt. Yes, the much of the spent money under Bush went to the Iraq war, and under Obama much of it went to 'stimulus', and both items hurt us all (through inefficient use of resources) while benefiting large enterprises.
danjayh··on Secondary shops flooded with unicorn sellers
I'll nail it down a little for you. I think it's going to be within two years, based purely on asset valuation : income ... which isn't a particularly sophisticated way to analyze it, but when people can't afford things anymore, they stop buying them, and that has predictable effects.
danjayh··on Secondary shops flooded with unicorn sellers
Yes and no. With regard to spreading, just prior observation that adjustments tend to spread. With regard to housing, the observation that the median home price : median income ratio is now above 5.2x, while at the last peak it was only at ~5x. The rate of growth is lower this time, but I don't think it matters because the ratio is still really bad.

danjayh··on Secondary shops flooded with unicorn sellers
I think that this is just the beginning. In my opinion, we're heading for a tech bust that's going to spread to the rest of the economy, and deflate additional bubbles (housing, for one). The government has been pushing cheap money for the better part of a decade in the name of creating the appearance of a 'recovery', but what they've really done is build a new house of cards. Make no mistake: the 'free' money that's been gushing into major institutions under the current administration is just as distortive and will be just as disastrous as the 'free' money that the last administration encouraged banks to put into the hands of sub-prime individuals.

Maintaining a near-zero interest rate creates artificial demand, and encourages investment of capital in inefficient enterprises. The thought process is "hey, I lose value with money in the bank. I'd be better off if I found something -- anything -- else to do with it!"

I think that once things take a turn, housing will also turn again, because in many areas the median house now costs enough that it's beyond the reach of the median person. That environment is unsustainable over a large time scale. Ultimately, we'll need a correction that sticks if we want to avoid repeating these events, and for that to happen we'd need a government willing to tolerate a politically unpalatable permanent reduction in asset prices.

(edit/note: I do find it odd that under a Democratic president, the major flows of borrowed cash (debt) have been directed to the big guys, while under a Republican president, they were directed to the little guys. Both were a terrible idea, but it seems backwards for what one would expect.)

danjayh··on Why Don't People Manage Debt Better?
Protip: The note 4 has a wonderful camera and quite often goes on bargain basement sales. If you're OK with used, you can pick them up for a song on Swappa. Personally I wanted a note 4 since it came out, and I waited until after the Note 5 was out to buy it. I love it just as much as if I'd bought it when it was fresh (plus the new phones don't have removable batteries or microSD, and who wants that?)
danjayh··on Why Don't People Manage Debt Better?
I find myself a bit bemused that the article specifically mentions student debt as an example of something that people can refinance but don't. I hadn't ever had any student debt until marriage, but since then (and until recently) my wife and I have been working through a great deal of it together.

As someone who has worked through paying down a large amount of student debt, I can tell you that student debt is very difficult to refinance. Our student debt balance was much higher than the median, but I believe that our experience with refinancing was very typical: we couldn't refinance our student debt at an interest rate that was even remotely attractive.

We reacted to the dearth of refinancing options by deciding to eliminate our debt as quickly as possible, and when we first got married we dumped about $35k into debt reduction. We chose to go after the high interest rate first, which was also the largest loan. Had we gone after the smallest loans first we could have paid off several of them instead of merely making a (significant) dent in the higher rate loans, and this is where the psychology comes in.

Dumping a ton of money into a debt without changing anything but your principle balance is discouraging. It was for us, and it is for nearly everyone else too. Personal finance counselors like Dave Ramsey actually instruct people to intentionally pursue the smallest debts first because the feeling of momentum helps most people to maintain dedication to getting out of debt, which in many cases will more than offset the difference in interest rates (paying down faster due to more resolve = less interest overall). We sold stuff and skimped like crazy people and we killed our debt, but it's a very common thing for people to run out of determination before they run out of debt. Since that's such a common problem, I'd say that it's not necessarily a bad thing that people pay debt in a financially non-optimal way if the method is at least psychologically optimized.

I haven't done any VHDL in about 9 years. Anyone know of a good site/tutorial to run through that starts out relatively basic and goes through to advanced topics? (bonus points if it has step-by-step instructions for a low cost / free for noncommercial dev environment).
danjayh··on Gig Work That Works
He says it works, but I say that at a pay rate of 1.5-5.0c/word, you'd have to be crazy to do it. Take this with a grain of salt; I'm probably a bit biased because the pay per "word" for software development is so much higher.
danjayh··on Negative income tax
Quite to the contrary - I feel that we should strive to provide excellent opportunities to all. I feel no need to provide a comfortable life straight-away, though - if we've provided the opportunity, the walk between being poor and living comfortably is something that I'm fine with leaving to individuals.

And the fact that you think my friends are living 'just above the breadline' is somewhat interesting to me; I would disagree. The own, not rent, a home. They have and cashflow a child (a very expensive thing these days, and considering the cost to society and the planet, it should be a privilege). Not only do they have food, but they never want for it (granted, they can't spend $15 on fast food for the family whenever they don't feel like cooking). They have a car. If that's 'on or slightly above the breadline', then we might not even be using a common vocabulary.

danjayh··on Negative income tax
I don't think that inequality in itself is a problem - it really doesn't matter how rich the super-rich are, as long as the vast majority of the people can afford basic housing, food, and transportation with an entry level job. Currently, the standard of living for the poor in the US is still much higher than the vast majority of the world. If that changes in a significant way, we'll have to become more competitive with the rest of the world, and that's not something we should do until we absolutely have to: although the relatively regulation-free manufacturing environment that exists in places like China has worked wonders for creating jobs and increasing wages, Chinese cities are not pleasant places to be. I DO think there is room to relax a lot of regulations (across the board - environmental, employment, and financial ... sarbox comes to mind), and I do think that this would help to bring back jobs, I just don't think that we should go as far as allowing the kinds of things that folks in 3rd and 2nd world economies get away with.

As an anecdotal example, I live in the midwest and have a couple of friends who have bottom-of-the-barrel jobs, making maybe $10/hr (which is what you get at McD's around here). That's enough that with careful management of their funds they were able to buy a very small house, eat modestly, drive a car, and cover the expenses for their child (we don't have smog laws here, so you can get a serviceable car for < $1k). They're not particularly motivated people, and haven't put any effort into getting better jobs, but they're also OK with living in the bad part of town in a postage stamp house. Nonetheless, their standard of living is dramatically higher than that of the vast majority of the rest of the world, and even though they're by far on the bottom end of the income scale, they're doing just fine.

We have fairly permissive zoning laws and building codes here, and people pop up houses like it's going out of style, so housing is very cheap compared to other parts of the country (the downside being that we have huge neighborhoods of small, cheaply built houses). Even though I don't particularly enjoy the look of these neighborhoods, they do serve a purpose, and I'm glad that we let people build them because they enable people like my friends to live on a very tight budget (and quite honestly, what somebody wants to build on their private property isn't anybody else's business, unless it's dangerous to people outside of the property in some way). True story: I needed a hay barn and I needed it to be extremely cheap, so I bought the ass-end of a cube van and plopped it on the back of my property. No flak from the township :). The chassis of the cube van is now living a happy life as a septic pumping truck.

danjayh··on Negative income tax
"the idea of a negative income tax is to treat people who are poor the same way we treat people who are rich"

... BS ...

There is nothing the same about taking a significant amount of money from one group and giving a significant amount of money to another group, even if you use a unified mechanism to accomplish it. Regardless of how you feel about the issue, let's at least keep the discourse honest.

I'll be honest: although most people around here are fans of basic income, negative income tax, etc., I am not for one simple reason: the second that more than 50% of the population is on the 'receiving' end of things and not on the 'paying' end, the motivation of society as a whole to enforce responsible governance and efficient use of government funds diminishes significantly. The pain of waste just doesn't sting so badly when it's not "your" money being wasted.

As a nation, we already pay a disgusting portion of our total income tax revenue toward interest (over 25% if you exclude FICA income). As painful as it may be, at some point our country is going to have to own up to the credit binge we've been on and either significantly raise taxes & keep spending the same, or keep taxes the same & significantly reduce spending to keep our debt problem from getting further out of control. Alternatively, the federal government could reclaim control of the money supply from the federal reserve and inflate its way out, but this is also really a form of tax; if the assets & income you had yesterday are worth less today because the government printed itself some funds ... you have been taxed, my friend.

All of these things, however, would be political suicide and I don't expect to see it happen any time soon.

danjayh··on Why Stack Overflow Doesn’t Care About Ad Blockers
Um ... it doesn't work exactly like that. If you leave your phone's WiFi turned on, you and your friends will be using Nomi sometime soon (so exciting, amiright?)! You see, the store/eatery/prison/airline/casino/whatever just puts the Nomi WiFi access point on their premises, and when you come in your phone tries to connect to it, and BLAMO, it harvests your MAC address. Now they have a unique identifier for 'you' (your phone's MAC), and they can keep track of how many times you go into the place, where else you like to go, what sections you like to browse (just a few more of the gadgets scattered in the store), if you've been to their marketing events, etc. etc. etc. Oh hey, since it harvests your MAC address, they can also tell who manufactured your phone. 'you' have an apple phone? Sweet! We've got ourselves a (probably) high-end customer.

Welcome to the future :(

danjayh··on Who Goes Nazi? (1941)
I just cannot believe what's on some of those slides. Here are some snippets -- imagine if you were to swap the races around, and replace every 'white' with 'people of color', every 'asian' with 'white', and every 'people of color' with 'asian'. If you do these mental gymnastics, some of these slides will seem incredibly offensive -- so how is it that they're acceptable at all, regardless of what the races are. Here are some juicy quotes:

"This is not work for white folks to lead"

"We need solidarity with our asian friends and colleagues"

"Some of the biggest barriers to progress are white women"
