Those same folks also do the math of 36*30 and decide that $1000+ is too much to commit to. It is not necessarily a problem of affordability as in, not having $1000 in the bank.
Hm, doesn't this violate the prime directive (or planetary protection guidelines)?
I'm not saying it was perfect, but it was far better than Outlook. And I have never once had to purchase recovery utils for Thunderbird, but to fix the fragile pst Outlook uses. I cant even count the number of times I had to do recovery for someone because IT was busy. Thunderbird never failed. At one point I just outright installed Thunderbird, changed the icon to Outlook and no one complained. I think I told them it was just the new interface.

Plus Outlook was a security nightmare anyways.
Polyrepos are the way to go:

- Semantic versions.

- Group components into reusable packages.

- Don't use git modules or other source cloning in builds, use native/platform package management.

- Access control is made much easier.

- Sign commits and tags.

- Code review either before- or after-the-fact, just do it(tm).

- Reproducible builds - strip out timestamps/random tokens/unsorted metadata.

- Create CHANGELOGs semi/automatically.

- Eliminate manual steps altogether.

- Distributed builds/build caching (distcc, ccache).

- TDD smoke tests should run automatically in dev on save with 10 seconds. Bonus points for running personal TDD sandbox on faster remote servers via rsync and trigger on file-save.

- Standardize on 1-3 languages.

- Services composed of simpler 12factor microservices, not monorepo megaservices. Deploy fuse switching, proxying, HA/redundancy, rate limiting, monitoring and performance stats collection just like macroservices.

You can't split monorepos after the fact, at least not without immense costs. You can always just put all your small repos into a big one.
No, he said "there IS NO dark side of the Moon, really; matter of fact, it's all dark."
The author talks about proponents of monorepos, but I thought when I read it: actually they are victims of monorepos trying to explain to themselves as much as anyone why they choose to suffer with them. (Actual reason: for $$$).

Nobody would choose to drag around every historical afterthought in the development sequence of long forgotten software going back three decades that no longer builds with current tools, just so they can work on a small library off in a corner. Software is getting written and added to these monorepos at a much faster rate than hardware and networks are able to hide the bloat-upon-bloat growth of them.
Space is like programming in that mistakes don't tend to be glorious, but just simple and mundane. The most famous example of this is almost certainly the Mars Climate Orbiter. [2] This probe was successfully launched and made it all the way to Mars. It was supposed to be an orbiter but ended up getting too close and most likely burnt up in Mars atmosphere. The culprit? Ostensibly some of the most qualified scientists with extensive oversight, regulations, and all that. And they were brought down by one operational system using imperial units, the other using metric.

A more recent failure has been on Curiosity. While it's been hailed a great success, it's had some major issues fulfilling with what was one if it's primary objectives - drilling into surface level targets and starting to measure things from the inside. It became inoperable after a few superficial utilizations. The most likely culprit? A piece of debris got caught in a drill feed mechanism. It could've been fixed by a man on the ground in a matter of minutes, but there is no man on the ground of course. NASA did manage to get a 2 inch drill without the stabilizers in the mid part of last year [1], thought there have been no updates since.

In many ways this is why I think people tend to rather overestimate the value of probes and remote robotics in general. Robotics, even to do relatively simple things, is incredibly hard. Trying to do not so simple things on planets tens to hundreds of millions of miles away in conditions unlike anything you can perfectly replicate on Earth? Well, you better send a few copies and just hope that what goes wrong on one probe/lander/etc (because something will go wrong) works out on one of the others!

I am thinking about going back to iOS because the general app quality on Android is horrid.
Except that in this case, if you think you have better ideas, you can code up your own fork, and try to drum up support for it. The open source ecosystem works far better than the political system, I find.
Does a lot of the pain from a monorepo come from trying to use a tool - Git - that is explicitly designed to support distributed repositories? Wouldn't things be easier if you used eg. Subversion instead? That is a tool that was designed around a client/server paradigm and had a single repository as its main use case.
Are you looking for a subset that adds up to X, or all subsets that add up to X?

Actually, thinking about it more, I'm not sure that matters. In either case, I think you could construct the power set[1] of the original set, and then just iterate over the results. For each subset with more than 1 element, sum the elements and if it equals X you have a candidate answer. You can stop at the first "hit" if you only want one answer, or just keeping going until you've exhausted the power set if you need them all. Implementing a power set generating algorithm is a solved problem[2], although you may have to stare at it a bit before you truly "get it". I did anyway.

There are, of course, pre-existing implementations of the power set algorithm. One I'm familiar with is in Guava[3].

[2]: https://stackoverflow.com/questions/24365954/how-to-generate...

[3]: https://google.github.io/guava/releases/21.0/api/docs/com/go...

Edit: I say "look at the subsets with more than one element" because otherwise, the one element set that sums to X, is just X and I'm assuming that's a trivial answer that you don't care about.
Simple Digital Analytics Hacks for Audience-Centric Marketing
1) There's no practical alternative to X.509 for PKI because the standards, tooling, and libraries simply don't exist and arguably never will given the momentum of X.509. A PKI infrastructure won't even make it out the gate if it can't interoperate with the existing X.509-based CA ecosystem.

2) Historically you never wrote ad hoc parsers. ASN.1 describes a grammar to be consumed by a compiler generator. The X.509 specification and extensions are almost entirely ASN.1 grammars with interspersed commentary. You can feed those grammars directly into the generator, and IIRC I've seen builds where the grammars were extracted directly from the RFCs. OpenSSL and other open source projects suffered from parsing exploits because historically all ASN.1 compiler generators were closed source, commercial products.

I don't disagree that it will likely be ugly. Open source options for properly working with ASN.1 are still poor, and these days even commercial vendors principally rely on open source toolchains. I've used the amazing asn1c which can be fed the official X.509 grammar and spit out a clean, strongly-typed BER, DER, or PER parser. But I've never seen it used by other open source projects. IIRC the mailing-list is mostly chatter from telecommunications contractors.

Bad ASN.1 support doesn't need to be the case. Hand rolling DER parsers is a choice. If we can write good generators for gRPC, we can write them for ASN.1. And from the perspective of C and C++ asn1c largely suffices.[1]

[1] My biggest grip with asn1c is that, IIRC, it still requires dynamic memory for grammars like X.509 with variably sized arrays and strings. It would be nice to see a compiler that supports generating statically sized fields and which simply errors out if an object doesn't fit within the field. Then you could use asn1c for really low-level, embedded firmware, and more importantly could greatly simplify application code traversing the data structures. ASN.1 supports specifying maximum sizes which could be used to size fields (and maybe are in asn1c) but that's a separate thing, and in any event X.509 doesn't make use of this (though I suppose it would be easy to amend the specification, formally or informally.)

I switched the other way around and was mostly surprised that iOs had barely an edge over Android. In a few places downright inferior to it (e.g. keyboard).

I can at least trust iOs to provide software updates for my device until 5 years of age. But I find it hard to see that many people value this remotely close to the price difference.

Grand Rapids is proof you can do it faster than 3% per decade.
People are already switching slower, and it is not because of the price (at least not in isolation.. the end of subsidized phones with phone plans did create a sticker shock across the board). Phones are now so powerful, especially iphones, that people have been holding onto them longer and longer for many years now. It is in response to that drop in sales that Apple had to raise revenue per sale or face a drop in overall revenues. Of course, they're postponing the inevitable, but in the meantime over the past few years Apple stockholders have benefited, and customers kept paying up.

Apple has a smash-hit already in the Watch, which is an amazing technological achievement and a sales success. But nothing they can do measures up against the explosive growth of smartphones, so all their innovation will be overlooked in any case. If the complaint is that smart watches are too small of a product for Apple (not what I'm saying, but a lot of eggheads out there) then "a luxury version of nintendo" won't sell nearly well enough to matter at all.
Fair point, guess when you have specs and failure rates to meet the effort/cost goes up dramatically.

Fair chance this rover can last a while though. Good luck to them.

Tuning a Typewriter
iPhone 5C is more than 5 years old at this point. Let's hear about your LG Zone4 experience in 5 years.
> The root issue is that batteries degrade over time, for everyone, not just apple.

What? No.

First of all, battery degradation is a design parameter. You can easily verify from apple own pages that iPads are rated for twice the charging cycles of iPhones. Apple intentionally included a low rated battery to limit the product life.

> iPhone’s did a good job hiding that away by degrading performance along with it.

And no.

Apple did an awful job, lets not forget the phone where crashing before apple introduced massive throttling killing the device performances. Neither of which sounds like a "good job".

Here's what a good job would have looked like (since apple sells top of the line devices at peak pricing): from the processor minimum voltage and battery degradation metrics figure out a voltage margin that would satisfy the processor constraints after one or even better two years of degradation.

Or, second best, start of with a throttled processor to begin with, but that would have ruined marketing precious "x times faster than previous generation", so they decided to do the shady thing: selling something as fast and killing it's performance six month after purchase.

And of all this what amuse me most is people defending it.
Inside out just means that the local equivalent of Earth's geologic plates seem to be subducting below the surface and fresh geologic plate equivalents are abducting back up. You can estimate how long a planetary surface has been exposed to the elements by the statistical distribution of number and size of craters. We have a reasonable idea of the likelihood of objects impacting Pluto, and it should have a lot of craters. Pluto's moon Charon has many more visible craters but Pluto has large areas with no large craters, so some sort of geologic process must be going on that's recycling areas of the landscape and covering or subducting the craters.

Given lack of fast erosion from liquid water or significant wind (in a very thin atmosphere), whatever geologic process is smoothing out Pluto is happening quickly compared to other points of reference we have.

I use the example of Earth's geologic plates, but that's only one possible explanation. There's also speculation about freeze/thaw cycles of the planetary material and atmosphere (since it has an irregular orbit), movement of water-ice mountains, cryovolcanos, and other theories.

Some examples:

Can this be used as short range SLAM
My understanding is the $29 is very much at- or below-cost. The all in cost is just not that cheap for anything involving a service that has labor, a warranty, etc. Not only is labor expensive, there's a chance that the customer's phone will be damaged in some way which they'd be on the hook to replace it, and it still costs money to ship to/from depot, operate the store where customers can drop it off, etc. Part cost /= total cost.

Also, a $7 battery from China is a gamble especially for something heavily used and physically next to your body a lot of the time. I'm sure you'd get a battery that had the same physical size and stated spec, but I'd be skeptical it'd have gone through the same QC. You could get one from a bum batch, or a relabeled one operating out of spec. You just don't know.

Same story here. The most talented engineers I know are either in their early 20s or in their late 40s/50s.

Of course it's for different reasons. Something many people don't want to admit is that a lot of talent comes from practice and experience, and someone in their 40s is much more likely to have 20+ years of experience than someone in their 20s.

The early-20s geniuses I know are talented for different reasons. The ones I am thinking about are people who pick up new things absurdly quickly; pick up on patterns very easily; have general experience in enough domains to make quick connections; etc. But some of them are extremely undisciplined (which may or may not be related).

Those same people with age, gain not only experience but also hopefully discipline. A combo like that yields you people like John Carmack and the like: Not just talented, but out-of-this-world "next level".

WP has good CS, but the quality of their offerings is lacking in my experience. The frames are nothing special, either in terms of design or construction. A lot of the frames are constructed from cheap plastic. And I don't think many WP frames offer features essential to durability like 5 barrel hinges instead of flimsy spring hinges.

I'd recommend Shuron over WP any day of the week. Made in the USA by a company that's been in business since 1865. Frames in acetate, and they offer real sizing to fit your head instead of a choice of "small" and "big" options. Barrel hinges, too:

http://www.shuron.com/

Shuron has great customer service, but they sure could use some help with their site which seems to be stuck in a 1998 web design paradigm. Quality frames at a good price, though!

Where WP has innovated is in online sales of "good enough" glasses for young people, as a taste proxy, and in fluffy content marketing like this article. But you can break out of the Luxottica eyeglass cartel of high prices and low quality by avoiding WP completely and going to Shuron and getting yourself a pair of Ronsir, Freeway, or Sidewinder frames. You'll save money, too.

How to Get Ideas for New Product Features
Noticed this is the same day as NASA got the Ultima-Thule photos. Was this announced today to overshadow it, like how Uber announced their IPO basically a day after Lyft's?

Want to avoid going off about conspiracy theories or who's more patriotic, just curious how the announcements actually lined up.

This (wikipedia-sourced) AP wire from Oct 22, 2015 when the Pluto flyby happened said they had re-pointed the probe for this flyby, scheduled for Jan 1, 2019, which it did exactly that. So we knew at least 3 years ago the exact date of Ultima-Thule -- spacework requires very good precision*. http://apnews.excite.com/article/20151022/us-sci--pluto-next...

The Chang'e 4 wikipedia page says it was launched Dec 7, 2018, only about a month ago.

So I get launches are well-planned in advance so wheels have been spinning a long time there too, but even so, they clearly must have known the two events would occur right around the same time, the Chinese one just a day or two after the American one.

Is this what a space race feels like?
