There is some evidence that appears to support the idea that there is a difference between calorie restriction and complete fasting. You sound like the type of person that likes to dig into the studies. Dr. Jason Fung does a good job of writing in plain English while linked to and referring to the supporting studies: https://www.dietdoctor.com/fasting-muscle-mass

The studies may not have been conducted among athletes so, testing your own body's response (by measuring lean body mass before and after a fast) seems like the best way forward.

I have read that people on keto diets or fasting have less "explosive" energy for workouts. I am not concerned that my body is going to cannibalise my biceps if I don't eat for a day or two. There is a lot more energy kicking around that is less important.

For me, it's worth it for the HGH boost: https://www.dietdoctor.com/fasting-and-growth-hormone
Yeah, killing inbox moved me away from google for mail entirely, and after that the dominos started falling. The only google product I use regularly at this point is YouTube, which I pay for to avoid ads.
In my experience, if you are a better-than-average software engineer at Google or Facebook, and you have an average or better manager, and you don’t have any ambition to get into management, the job is pretty unstressful.
Since you are responding to someone comparing US domestic (in town) shipping prices to international shipping price, I don't see how you are not talking about "terminal dues".

International freight costs could explain why international shipping is more expensive than domestic shipping, but even if international freight prices are 0, they can't explain why domestic shipping is more expensive than international shipping.
Panda's discouragement of "row-by-row" is a feature and not a bug.

Many operations are drastically faster (10x or more) when done over columns instead of over rows.

This is a big part of the Hadoop -> SQL revolution we have had in recent years; people have realized that columnar SQL implementations are just insanely fast.
Not even sure how its a "follow up" as it has nothing to do with the Iron-Ion battery. Lithium is lighter & more energy dense and will take more chance.

I think where you're coming from is likely something like this Lithium battery steals the press thunder from the Iron ion battery. It's likely the Lithium battery will be used in portable, vehicle applications and if it actually has any benefit the Iron would could be used to store surplus electricity for the grid.

They are detention centers. Normal process by most countries upon illegal entry is to send you back. We actually grant people the option to stay and take their chances on appeal rather than just send them back. They can choose to go back. A gulag does not allow the option to return whence you came.

What do you think would happen if I took a boat into Japan, China, S Korea, South Africa, Romania, Ghana, etc., and as a foreigner got stopped asked for passport and didn’t have a stamp? I’d get sent back. No chance to stay in a tent and appeal.
I have been waiting for essentially this, but with racing games onscreen. Does anyone know if they allow, or plan on allowing third party apps and games?

I can see a game like Mario Kart being very popular.
I don’t mean to be disrespectful but I find this view weird. The pentagram is on the slides for this technical presentation. Millions of regular folks won’t be watching this video I would think. Maybe I find it weird because I don’t place any significance on that symbol, but you’re talking about slides on a pretty obscure talk.
Well one thing is that here there's a full 12 months of sunsetting going on, compared to a lot of "we're killing the product and you have a month to export your data"

A year is a pretty long time!

I am curious about usage numbers on some of these though.... like if these products were actually really successful I don't think Google would actually kill them.
Wouldn't that also have sales tax and product liability consequences?
Angering China Can Now Get You Fired
I was no particular fan of children or parenting before, but eventually I decided that raising children is such a significant part of the human experience, I'd be opting out on a huge chunk of what this life has to offer. Sure, it has major downsides and risks, but is also unmatched in its potential emotional and existential rewards. Going without may be perfectly rational for a given person, but for me, the opportunity cost tradeoff weighed in favor. That said, I became a father in my 40s after having had a pretty good run already, and that's definitely not something I would do any differently.

TL;DR: YOLO/FOMO.
> Have you worked much with evolutionary algorithms?

Not really, like I said, there's usually better algorithms than genetic algorithms. They're fun to play around with, though.

> It also seems you think that evolutionary algorithms are somehow analogous to biological evolution. To what degree do you think that is true?

The general principle - selection and random mutation - is the same.
Oh I know, me neither. But I've been denied headcount several times. I don't want 2000, but envy the magical ability to get at least a bigger number.

Unfortunately, time and again I've seen that the person who grows that big team, etc, is an unqualified idiot asshole. Good guys don't frequently win.
Google has largely failed to diversify. In contrast with Amazon, or Microsoft they only have two closely coupled revenue lines ( search and ads ). Overall this makes them vulnerable to a shift in the marketplace such as increased demand for privacy.
That is so catastrophically false I can't even. Capitalism has empirically been, by several orders of magnitude, the most powerful force in the world for eradication of poverty.

But hey, when you define poverty by relative income levels instead of absolute levels of depravation, you can say what you said. But you are forgetting the tragic suffering of the historical poor and those under socialism, feudalism, and pretty much all of history for all time.

Today's $10k/yr poor live way, way, way better than the hanseatic merchants of yore.

There is no enforced policy that keeps people down. People just look far down from above, even if the tide is actually, in reality, lifting all extraordinarily rapidly.

Abd startups/kickstarters/people set prices "which should allow them to scale" - but they are always based on assumptions which sometimes turn out to be incorrect is that scale happens to be several orders of magnitude larger that the people who made those assumptions.

We don't want government departments to be setting fees based on worst case upper bounds of processes with poor Big O performance. Nobody wants to fund through fees or taxes, say, a DMV who are perfectly set up to reissue every single driver's license every day. There's a very reasonable assumption that driver's licenses are lost/stolen at a fairly consistent rate and to size the department and processes to perform "well enough" at that replacement rate. If a startup found a way to monetise revoked driver's licences, and started offering to buy them off people for $50 resulting in thousands of extra license replacement requests - the DMV would be perfectly entitled to change their rules and say "you only get one inexpensive license replacement every 3 years. Additional replacement license will now cost $1500 each". (Not a _super great example, because there's presumably laws against selling your driver's license, but ignoring that - I think this argument stands...)
The book Range: Why Generalists Triumph in a Specialized World
by David Epstein https://www.goodreads.com/book/show/41795733-range argues a lot for this as well, and goes on to discuss numerous examples where generalists have made the breakthroughs and/or excelled in some way, due to synergy, overlap and inspiration.
Hi! I work at Abl and this is related to what we do. Take a look at our site, ablschools.com. You can shoot me a note if you’d like: ishwar@ablschools.com
Very odd study. The usual reason why people introduce sentiment analysis into a model is that they don't have enough data or aren't comfortable enough with NLP to train a classifier against their own labels. Instead they grab pre-trained sentiment analysis model off the shelf (e.g. Vader) and now the have the much simpler problem of determining if a binary variable (sentiment positive/negative) is related some response variable which can be tackled with statistics 101. This can also be seen as an attempt to leverage transfer learning because such models are trained on a very large corpus with gold-standard labels; this can be beneficial when your corpus is too small to be a representative sample of the entire english language.

But in this study, they manually label and train 8,000 sentences taken from their 10-K dataset. (A terribly small corpus, but the unsupervised word embedding step should help with that, at least a little.) Not great, not terrible. But they label them with sentiment and only later look for an association with the real variable of interest (abnormal return!) Why the extra step? If you're training your own model anyway, why not label the data with the real variable of interest from the start?

I also don't see any attempt to control for the obvious confounding variables, such as the actual numbers in the 10-K. This leaves open the question of whether the effect is mediated by the other, more structured information in the filing. It's entirely possible for sentiment to have some mutual information with the variable of interest but for its benefit to entirely disappear once these are taken into account (a phenomenon known as mediation.) I would prefer to see this a single end-to-end model which is fed both the unstructured text data and the structured financial information as input features and the actual performance change as the output. The actual contribution of the unstructured text data could then be assessed with a tool like LIME (Local Interpretable Model-Agnostic Explanations.)
Perhaps. How do road bikes on trainers handle out of saddle riding? Many spinning classes involve out of saddle riding.
From the sibling link:

> This massive shipment was noteworthy not only for its size, but also because it destroyed one of the Uintah Railway Company's trucks. The truck's brakes failed and it started coasting backwards after breaking a drive chain while struggling uphill, loaded with several thousand bricks. The truck then turned over and caught fire. The driver was not injured, but most of the bricks were lost.

I imagine USPS pricing didn't account for that incident!
It's dangerous to throw extra sensors into a Kalman filter, because if the sensor goes bad it'll corrupt the output.

Angular rate sensors are extremely accurate, far more accurate than a thrust sensor could be, so it probably wouldn't improve the overall accuracy anyway.
Except now your readers have to click out of the RSS reader, rather than stay in there and read. I find it jarring and obtrusive to do that, and prefer just to visit the site instead if they RSS did this.
> I think Raptor might be the first Methane-based rocket engine as well.

If I remember correctly, John Carmack's Armadillo Aerospace tried burning methane in an engine. Though I don't think they were the only team - or even the first one.
Wikipedia lists a few methane/LOX engines that have been used in test flights. For example, NASA's experimental Morpheus lander had fifteen or so test flights -- all low altitude, but some higher and longer lasting than StarHopper's hop today. It's also being developed simultaneously with Blue Origin's BE-4 engine, which hasn't flown yet, but has been through an extensive ground test program, and will be used on both Blue's own New Glenn orbital rocket and on ULA's Vulcan. So depending on how quickly the relevant test programs go, Raptor may or may not wind up being the first to be part of an orbital vehicle. (But as neither Vulcan nor New Glenn is currently slated to use it for the second stage, Raptor will very likely be the first to go all the way to orbit.)
What a bummer. By far the best candidate management software I've used. I guess it's not too crazy complicated where another company couldn't ape all the features.

Being "on the verge of a recession" means nothing. There have been people constantly predicting the next recession since 2011. And there was zero talk of an economic downturn in 2007.
I still use Hangouts for SMS, but the product is half assed at best. I wonder when Google will kill Hangouts for good.
I can tell from the goals he scored as well.
Yeah I know, but from the perspective of a customer it sounds absurd.

Personally I'm fed up with single entities such as Microsoft using TLDs for every damned thing, it makes it very hard to identify what is and isn't legitimate traffic. It also makes it borderline impossible to configure "whitelisting" firewalls or proxy servers.

I got to wonder what fraction of this is incompetence ("we can't use our own domain because of bureaucracy") and what fraction is deliberate ("everyone has blocked microsoft.com so we used something else")...

“Made-up language” is a bit harsh. The Mathematica company has hundreds of millions of dollars of revenue, right? It makes sense for his public communications to use it, just like you’d expect to see the guy who wrote Haskell to give examples in Haskell.
I'm just saying, if your rule is going to be "eat whatever you want during your window", that's never going to work for a food addict. Ultimately you will have to count calories regardless.
Agree that that is an awesome article.

Suggest you include the posting date on that page, as reading it, I wasn't sure how recent the info was. I was then shocked to find that these vulnerabilities were identified late last year. Some of these are security 101!
Almost every successful Google product over the last 15 years has been the result of acquiring an already-built product and marketing + distributing it well: Youtube, Nest, Waze, Doubleclick, Android.

Products that are organically created within Google (even Google Hire, created via acquihire) have a pretty awful track record.
If you're an end user, the only relevant perspective is noticing that the company is unreliable. That they're maximizing their own interests is something you can take for granted, but it's of little comfort or interest.

This is so awesome. I’m really interested to hear how you progress, build out more solutions, etc.
I don't think their marginal costs increase the same way as a gym. People using their bikes more just means somewhat higher load on their servers for users using the workouts (and I suppose more demand for new content). There is a cost, but I'm guessing it's much lower than the cost of the added wear on gym equipment and the need for extra staff and other costs associated with a gym.
IMO, YouTube is their only killer product at this point. Runner up might be Maps, which I occasionally use for Street View, but I've been able to get away with MapQuest most of the time for directions. Otherwise, I've completely replaced everything in the Google ecosystem and have been very happy. Sure, Google's got all the algorithms, but that's not something I want in the first place.

> only have two closely coupled revenue lines ( search and ads )

There is (practically) no "search" revenue that is not "ads" revenue. Ads is close to 90% of all Google's revenue. The remainder is not broken down in the earnings report, although I suspect it's largely their cloud computing business. Thus, Google's two revenue lines are really ads and cloud, with the latter much smaller than the former, and probably with a lower margin too.

Are you comparing Linux reliability to Windows?

I have a Linux desktop and a laptop (Linux preinstalled) and resume from sleep works about 50% of the time (usually GPU driver crashed during resume).

I've run normal updates that have broken the boot, or cause X to stop starting up. I get more nervous running updates on Linux than Windows.

At work a guy changed the password on his LUKS volume and it hosed his entire encrypted partition and he lost all his days.

Linux is very easy to break and very hard to fix.

Windows is definitely more reliable as a daily driver than Linux, in my experience.

In the short term you’ll move less bricks for sure.

But in the long term, I wonder if you as a group will be able to discover movable bricks that you wouldn’t have seen or cared about on your own.

And maybe those bricks are both more valuable to move and more likely to successfully get to their destination, because you’re doing so as a group not as an individual.

Not sure.
In this context you're not spending enough time on it to become an "expert beginner". You're not getting the same three months of experience a dozen times, you're getting them once.
Ask HN: Developer Focused Podcast Suggestions?
Hi folks,

Looking for some great developer focused podcasts. Tech focused or general software development.

Searched HN and there was a post about four years ago, but haven't seen anything recently.

Ones I know about already:

Software Engineering Radio

Reboot.io

Authority Issues
Now let's argue over which one.
None of these people should be deciding the status quo tbh, neither should SV
Very few sites have the full content in the RSS feed. Some even just have the titles. It doesn’t really effect ad views.
Not sure what the HN rules are for self-promotion but my team and I recently launched an ATS/CRM called TalentAdmin. We're currently more geared towards smaller businesses but slowly growing into larger customers. We're not a perfect fit for everyone but we're very strong in structured interviews / scorecards, support, and at a price competitive with Google Hire.

I definitely feel like I'm more effective coming back to something with more world experience than I was when I only knew that thing. Technically adept? Maybe not quite as much (after all, I'll be rusty and the state of the art will have moved on). Able to make better things? Certainly.
How delightfully smug to look down on people who like different things than you do.
Thanks for your insights. Although my question sounds a bit sarcastic, I wasn't really sure what made them different. Looks like they got something there with the flexibility and quality.
>it’s absolutely useless if you want to go and browse some shelves and borrow some books

Libraries cannot survive by catering to a smaller and smaller subset of people who are habituated to using a mostly obsolete technology. On a cost-per-loan basis, most libraries would save money by closing their doors forever and simply buying books from Amazon whenever someone asks for one. Local governments look at the lending data and quite rightly wonder whether the money could be better spent on a thousand other things.

To secure their future, libraries are becoming a sort of egalitarian third space. They provide internet access for people who don't have it and training for people who have been left behind by technology. They provide a place to relax and socialise for people who can't afford a $4 coffee. They provide a venue for community events. They provide young people with opportunities to engage in the kind of self-guided learning that actually matters today.
"Brogrammer" is just a term that means "male programmer I don't like."
To the issues raised in the article? Unfortunately I don't have one to present to others. Everyone is different and my only advice is to find a professional that can talk through specifics and provide the right approach.

If you're asking more personally, I identify with a lot of the same struggles as outlined in the article and here in the comments, but I stop short of feeling the excessive anxiety. Instead I'm just paralyzed by inaction and have low energy for pursuing any ambition.

I'm currently in the process of ruling out all other possible health factors first (ADHD, hormonal imbalances, sleep deficiencies, metabolic issues), but if those end up being exhausted I'll probably explore Cognitive Behavioral Therapy.

Training myself to have healthier mappings between emotions <-> thoughts <-> behaviors seems to me like the best approach. And then maybe I'll be capable of applying the sort of "just do what you feel like" advice you provided above.
