>The Government Accountability Office’s preliminary findings reveal a pattern of problems with turbine blades that pump fuel into rocket engines

>The crack-prone parts are considered a potentially major threat to rocket safety, the industry officials said, and may require redesign of what are commonly called the Falcon 9’s turbopumps.

>A SpaceX spokesman said “we have qualified our engines to be robust” to such cracks but are “modifying the design to avoid them altogether.” The pending changes “will be part of the final design” for the Falcon 9, he added, “in partnership with NASA to qualify engines for manned spaceflight.”
I'm always a little surprised about how naive HNers are about corporate sales (and BD).
We can bikeshed all day how many engineers they "really" need, but for $400m in annual revenue (plus that growth) they probably need a 400 person sales org minimum.

I have to say that I'm constantly impressed with the level and tone of discussion in purescript development. That thread is a pretty good example. It looks like your wish is being fulfilled :-)
As someone stuck with Windows Vista (no sarcasm intended, although I shall be upgrading later this year when patches stop coming) I beg to differ. There is a continued degree of improvement since the Windows 9x days and in the meantime Windows have displaced Mac OS and Linux in certain market segments because of its code quality not despite of it. It is impressive that they have maintained great legacy support alongside it.

The current tirade against Windows 10 is not really that different to the period after Windows XP came out just because it is radically different to its predecessor, yet the latter eventually became the most long lived MS product ever. A similar torrent of FUD did kill Vista's reputation, but as we all know Windows 7 is just minor upgrade but this rebranding is enough to pacify the most vocal critics. Make me wonder if Jobs was right that users really have no idea whats the best for them.
do we really want to get into this discussion?

I use to have a Firefox OS phone (the Flame), but since I broke it last july, I switched to Android and 7 month in I still miss my FFOS phone :/.

The original announcement that Netscape would release Mozilla as open source included some FAQs, including one question along the lines of "are you going to release your own operating system?"

"What else is new here" is you can't have any downtime, and you have to have a strategy for having your code work against the data in all of those transitional states during that process.

A lot of migrations would be pretty trivial if you could have even a couple hours of downtime, but in an expectation of 24/7 availability that is no longer acceptable in most situations.

I'm hoping that my home country Tunisia can replicate (at least somewhat) the Israeli success story.

I don't believe I'm the only one in Europe that has a special sympathy for your country. But trying to replicate Israel spirit? I don't think so. It's like when people over here talk about making an "european SV", not very realistic. I neither see my country doing anything similar if you find consollation in that :-)

There are two reasons. One that someone pointed in a downvoted comment nearby: funds from governments (Israel and USA). The other one is a ruthless killer instinct. Both are shared by SV. If you've been around here for long enough, you might remember a couple of references that show clearly both factors. For government backing there was an article about SV origins in WW2. The other one is a YC standard interview question about how founders "hacked the system" for their own profit.

Yesterday I got in a somewhat esoteric argument about how righteous people get very strict about abstract ideas like environment protection. This is the default actitude for many smart people. So the questions that matter are: are your government willing to put a lot of money to grow a sharp industry, and is "selfishness" taboo in your society? Otherwise, we're doomed :)
Watch out! Some of this code may be GPL-encumbered. The decoder for JSMpeg is based in part on "Java MPEG-1 Video Decoder and Player" [1], which is licensed under the GPLv2.

If that's true, then I'd recommend not using either .NET or VSCode if cross platform matters to you.

Alarm 7:15. Snooze. Snooze. Snooze. Snooze. Make espresso, add some milk, drink in bed while reading Facebook. Resolve to quit Facebook and contact friends directly instead. Shower. Pack rucksack, get dressed. Cycle to work, between 15 and 45 minutes depending on location. Check emails and flag those I should action that day. Change out of cycling clothes. Do something productive, then duck out for coffee and buttered toast at 10:30am.

Since digital content is close to free to distribute (distinction, not free to produce) there is an ever expanding amount of content available, approaching infinity. To stand out in an infinite sea of content, the upper bound of what you would need to spend is an infinite amount on ads and marketing.

This also works for products. The more a product or industry is commoditized, the more important marketing and branding becomes.

Another interesting bit:

>> As a database specialist not only will you work on the database, but also the application's usage of the database. As a result a significant amount of experience with both Ruby and PostgreSQL is a strict requirement.

This is a mistake. The number of DBAs who are good with postgres is very small compared to something like mysql. The truly talented pool for such a position is too small to expect them to also be a developer. The very mention of terms like "ruby" and "programming" should be removed from that job post. It's not a realistic expectation.

Most of the battery advances have been inside the realm of lithium ion, so that's no surprise. These price drops are a specific stage in technology/manufacturing advances, not something that will continue indefinitely.

You can be confident that lithium ion won't be replaced on that short of a time scale. Nothing's ready to do so.

Ultimately, the batteries will win, but into your calculations consider the time value of money: how long will a given usage take to reach 1000 cycles. On the flip side, gasoline prices are volatile, and electricity from solar keeps getting cheaper, too. In a steady, non-volatile price march.
In the long run, the probability of this being exploited is approximately 100%. I'm surprised they left in such an obvious loophole.
Yes, but roughly half of all papers will never even be page-loaded from the 'official' source (if you believe my recollection). I am not a CS researcher, but I would imagine that of 10 people that cite a paper, at least one will bother to download the original paper or look up the source. Hell, even 'vanity' page-views of your own work would have been counted in the paper that I mentioned, and that is with many authors on a single paper too.

I honestly don't know what to make of it really. I at least bother to look at my papers once, if only to show my family on the Holidays, and I have a lot of so-authors that may be doing the same. Are most researchers so fed-up with their own work as to not even bother looking at it again? What is going through their minds concerning their efforts? It's just ... heartbreaking. At least half of researchers don't seem to care at all, not even the people that put all that time and effort to get their research out there. Like, what are we doing with our lives?

The depreciation of a new car is, in large part, based on powertrain wear. If relatively inexpensive battery replacements/upgrades are available, that changes the value of a used car. It could reduce depreciation substantially.

I would be surprised if a well-maintained, crash-free electric vehicle in a climate without road salt wouldn't be worth battery replacement.

It's also not the correct economic consideration; you have to compare the value of a used EV vs. that same vehicle with a battery upgrade. If that value is greater than the cost of the battery, that's all you need. High depreciation of new cars makes the upgrade more attractive, actually, if you're considering resale value; upgrading an old car would allow you to avoid the 'off the lot' hit.

We tried raising money for 5 months last year and we talked to partners from about 20 European VC, but we were not successful. We got no or low-balling offers at best. I guess we were missing what people call "social proof".

This was our pitch deck by the way (not meant for marketing but for context): http://www.instaff.jobs/download/InStaff_Pitch_Deck.pdf

We don't need money, because we have been cashflow positive and growing for a while. And since fundraising was hyper time consuming we will not get back to fundraising again.

But I don't want to "rage" against the VC scene here. To each his own and I wish everybody who raises money successfully to grow his business all the best.

This is from the linked paper.

'From 2010 to 2016, battery pack prices fell roughly 80% from ~$1,000/kWh to ~$227/kWh (Exhibit 4).4 Despite that drop, battery costs continue to make EVs more costly than comparable ICE-powered variants. Current projections put EV battery pack prices below $190/kWh by the end of the decade, and suggest the potential for pack prices to fall
below $100/kWh by 2030'

So in 6 years the cost of battery packs has dropped 4 to 5 fold. And by 2030 may drop a total of 10 fold vs 2010 prices.

The downside to this approach is that you need to get copyright attributions for anyone who submits code to the project. This is often a fairly large barrier to entry for contributors and I suspect that the author will continue to have poor engagement for outside contributions.

Now, from a practical point of view, that may be perfectly fine for him. If he's not getting many contributions anyway and doesn't really care about it, funding the project through license sales can make sense. Sometimes I think people don't think about the trade off that's required, though. I've seen people get frustrated with the lack of outside participation.

However, I agree with you. In this case, it seems like a smart move.
100% solar? we are super far from that and we need anyway to produce energy even at night.
When a battery "can't" be replaced on a consumer device, that generally just means you need a soldering iron or to pry it open. Many car repairs are already vastly more difficult than that, so those barriers would be negligible. It's hard to think of an equivalent.

My manager of the last couple of years asks the same handful of questions every single time, a structure that I felt a little skepticism toward when he was detailing it in our first such meeting.

Hi Patrick. Thanks for the ongoing great info you provide. Do you have any thoughts on how a desktop/native deployment impacts these timeframes or figures?
My wife and I have a 2012 Nissan Leaf and a 1999 Toyota Camry. The Leaf gets driven every day. The Camry at least a couple times a week.

Before getting the Leaf I monitored my driving habits. The only days I ever drive more than ~20 miles are because I am going somewhere outside my daily routine. If you have access to a second vehicle, I would really recommend taking a second look at current EVs. Where else will you get heated seats, rear view camera, gps, alloy rims... all on a 3 year old car with 20k miles for less than 12k USD? It can be an amazing deal. Additionally if you have access to free charging at work it is a huge incentive.

It's not about uptime, it's about the service existing at all. Even if you are fine with an hour downtime per day; at the end of that hour, you'll still need to bring it back online. The "aaS" part is about taking that load off. The nines are a corollary.

Concretely: a dedicated server leaves you with a lot of extra work. A packaged, managed service doesn't. E.g.: s3 for static files vs an nginx server on a VM. Even if they cost the same, s3 would still be a better option for git-scm.org.

Plenty of states already have regulations. California has rules about how parties elect their boards and whatnot, for example, and officially recognizes parties.

I agree that we should reduce their influence. That would be the opposite of doubling down on our current system of treating them like pseudo-branches of government.

One way to accomplish that would be to ban official recognition of parties, require them to fund and run their own primary elections, and move to multi-member representation districts. All of these things can be done at the state level for state and local offices.
Not using image layers to begin with. You can't reasonably do that with Docker or other software that isn't aware of the dependency graphs of the software that it runs. Docker just runs some arbitrary commands and maintains an opaque set of disk images. Seems to be the best you can do there. However, if one were to use software that actually understood the full dependency graph, you wouldn't need disk images at all and you'd be able to share storage without involving special file systems. In GNU Guix, a functional package manager, we can make containers for arbitary software without any duplication because we know the full dependency graph of the application. Applications may share sub-graphs so they are only on disk once. If two programs depend on libpng, libpng and its dependencies are only on disk in one place. With a functional package management system in place, containers become a relatively simple matter of creating namespaces and bind mounting the dependencies. No image layering, no special file systems, just simple bind mounts.
