Ask HN: Created LaunchRock page for my project, now what?
Hi all,

I have created few days ago a landing page with LaunchRock for my new side project (http://cv-rocks.launchrock.com).

Now what? What could be the best ways to advertise it in addition to the standard social sharing?

And how do you think I might improve it?

Thanks!

We updated from Rails 3 to 4 ~1 month and a half ago. Our Gemfile has 138 lines and we have ~70 models. We updated everything and did a full regression testing to fix all the new bugs within a sprint (2 weeks) while also working on a bunch of other tasks.

> They don't follow a trajectory. They might just travel straight down from a geostationary orbit

That's not how orbiting works. If you want your projectile to travel straight down, you need to cancel all it's orbital velocity. For geostationary orbit, that's 3km/s of delta V needed.

Obviously, you can de-orbit with less delta-V, but then guidance starts becoming necessary.

There is going to be some kind of burn to start de-orbit, you could simply monitor for that.

In some cultures, "overuse" of personal transport (if we want to put it this way) is a vicious circle of context and individual; it's not simply a fault of the latter.

Public transport underdeveloped -> more people use personal transport -> public transport develops even less, city develops around personal transport -> vicious circle.

Of course the individual it's a purely not victim, but in certain contexts, using the car is a necessity. In such cases, a strong collective effort should be made to reverse the situation.

Quest-driven OpenStreetMap editing for Android
The German government, the traffic minister in particular, are disgracefully downplaying the problem and working hard to water down any new regulations to the point where they don't threaten the status quo.

However, cities may well reverse the government's efforts, because they have a duty to limit the (real, measured) inner city pollution. So cheating on the dyno won't help car makers.

The downside is that the cities' only regulatory approach is more heavy-handed: things like banning all diesel vehicles on particularly bad days, etc.

But it might sour diesels for citizens, so all the lobbying efforts may well have been for naught.
PHP Performance: More CPU Cores vs. Faster CPU Cores
after a certain size not every person can be answerable to the big boss, you need an actually structure.

you don't need to create a middle management structure from the get go, just have a chain of command.
Taxing by weight and emissions and cost are a more pragmatic version of this.

Cars, and houses, are to a degree used for status signalling. With products like that, heavy taxes increase total utility since you can still have a nicer car/house than your poorer neighbour, it's just that all cars/houses have been bumped up a rung of show-offiness. Compare Europe to the USA for example. Even the American electric cars are comically large by euro standards.

(Other co-benefits are improved safety, an analysis of CARB regulations suggested that they paid for themselves just by reducing death and injury by encouraging lighter cars, even if you ignore air quality issues)

1) You don't get citizenship, but your kid(s) likely will, after they study and get a job there.

2) There are many native Chinese property managers in these markets (coastal US, Vancouver, Sydney) specializing in supplying info and property management services to mainland Chinese looking to invest/speculate.

3) Expensive is relative. Seattle property is about half the price of property in Beijing or Shanghai (while the average income is about 3 to 4 times as high)

4) As others have noted, stocks are a lot more regulated. And in China they're perceived as much more speculative than property.

I think it would be silly to prepare for long-term unemployment in the Bay Area. I can move to within a few blocks of my parents' house and live almost the same lifestyle for ~50% of the cost, or a lifestyle befitting a long-term unemployed person for ~25% of the cost.

Moving costs something, but would pay for itself very quickly. If I leave my furniture to the Craigslist scavengers, just the lease-break fee of 1 month's rent and a plane ticket with a couple of checked bags.

At some point it becomes important to start the ball rolling on that sweet compound interest, pick up the preferential tax treatment (saving the max of $18k to a 401k would only cost me about $10k), pay down student debt early for a guaranteed 4.5% return, and (yes) travel and enjoy being young.

Effectively, the fund I'm working on will be worth even more than a year, as long as I relocate.
Since a few are mentioning pirate books.

My favorite ones are the books written by Ambroise Louis Garneray, which also served under Surcouf, before eventually becoming a painter after his life as pirate.

However even back in his lifetime some would state he colored his memories a bit, so that they were more interesting to read.

Of course, only he knew how much that was actually so.

I've been working with German OEMs for years. It was a well-known secret that the regulatory emission tests were a sham and would routinely be circumvented.

I personally wasn't aware they actively tried to cheat on the dyno -- the European regulatory tests were so obviously, deliberately weak I didn't expect it was necessary.

But, yeah, a lot of people would have had to know (or at least have heard the rumors) about this. Combustion process engineers, requirements engineers, programmers, testers.

Fire Phone definitely had it (see https://www.wired.com/2014/06/amazon-fire-phone/ for example), GT5 called the feature "Head Tracking" but, since it is played on a fixed display it was essentially tracking the direction of gaze in that setup, from the POV of gameplay I don't see much difference between that and true eye tracking.
> Solar and wind power are picking up steam (pun intendend :p).

Yes, we produce more solar and wind power, but the level of electricity consumption has also increased. Are we outputting less CO2 for electricity, or does all the solar and wind just come on top of what we already had?
They probably just underestimated the gullability of the average American voter.

Imagine if some nerd had spoke up at a Shell meeting and said his analysis of the American voter suggested that they could just claim it was a Chinese hoax and that would be accepted. Most intelligent people would find it hard to take that seriously, so they only found out by continually pushing the boundaries of what they thought the public would accept.

Unfortunately for the world, there was a certain group of Republican voters that were very susceptible to their propaganda and so they could keep pushing into the absurd.

I don't believe religion taints of devalues marriage. I'm trying to understand, based on the comments, it seems like they are only still married because of their religious beliefs. This sounds like they do not love who they are married to which to me is wrong.

I'm trying to understand why they say that they continue to be married because of their religious beliefs.

Plenty of religious people, and plenty of non-religious people, stay married for life.

But I have literally never heard someone say they strive to stay married because of religion.
This smacks more of "I am married with kids, a full-time job and a severe lack of time".

If that is the case then you just need to grab time as and when you can. You will find you can find half an hour a day at least. The limited time will help you focus. I find I get up early or stay up late to make time for this.
Hi, Alex

great thought about travel , i enjoyed your post
Not really !! But it would personally motivate me to know how many people, older than me are still great at programming !
Depends on where you are.

That's not true in California; there's a lot of flexibility in deciding that here. For example, if the separation will mean that one of the two parties will have to reduce their standard of living below that of what was enjoyed during the marriage, that can result in alimony payments.

A fascinating article. There are similar parallels with the smugglers and poachers of my area of the UK - rural Dorset. Characters like https://en.wikipedia.org/wiki/Isaac_Gulliver managed to become respectable, but at the same time are subjects of a lot of folklore and tales.
Citation needed.

This is clearly subjective. There are many aspects of games and many games implementing these aspects. Some pre-1990 games excel at some of them and some newer games excel at others. Apples and oranges. For example, as a medium for interactive storytelling, in my own opinion, only very recently have games managed it in a way that I found more engaging than non-interactive mediums in terms of storytelling impact. Part of this, for me, is that decisions actually impact the gameplay and continuing story and things like lifelike facial animation. When engaging visuals are combined with rock solid storytelling, you've got a great movie, but when you add solid interactivity and gameplay, it really becomes something else. This just wasn't possible pre-1990.

You're obviously talking about the simple "small number of mechanics" pure gameplay games (the tetrises, bombermans, pacmans, space invaders etc), sure, there are some great and long-lasting games, but there are plenty of amazing modern games too in terms of gameplay (eg Rocket league).

Obvious troll is obvious but for the sake of facts:

a) The Islands were uninhabited when the British settled there.

b) Argentina didn't even exist as an independent country when the British claimed the Falklands.

> It's not like they're anywhere close to London, are they?

It's not like Argentina is anywhere close to Madrid, but there seems to be a lot of people of Spanish descent living there.
What a beautiful and well-articulated comment! The issue of value-compatibility (cultural, social, psychological) for successful communication/relationship is immensely underestimated and there is therefore a huge lack of guidance and sensible warnings for a human starting their mating lives outside of circles perpetuating traditions. Many of us get eaten in that jungle and wake up mamed a couple of decades later... I hope your comment helps someone out there realize how important it is to spend energy on "finding your tribe" in order to "date your species" as Reid Mihalko puts it.

I'm unmarried, so I'm not in the situation yet, but I would be very uncomfortable uttering the standard "till death do us part" lines during my future wedding ceremony. I think it's unreasonable to expect anyone to promise that, at any point in their lives.

I would certainly promise to remain faithful to my partner, and to do my best to support them (emotionally, financially, etc.), and to make them my #1 priority in life, but I would never make a promise that precludes the possibility of divorce. I take promises very seriously, and I wouldn't make one that it's impossible to know if I'd be able -- or even want -- to keep.

I can't find a source for global emissions, but for the EU the emissions are actually lower than in 1990: https://www.eea.europa.eu/highlights/eu-greenhouse-gas-emiss...

I expect China's emissions to be through the roof compared to 1990, on the other hand they've noticed the problem and unlike Trump's head in the sand approach, the vast majority of their energy investments are in renewables.

So things are bad but they're looking up.

Making an invading force pay reparations isn't admitting their sovereignty. By that argument Germany has bought & paid for much of Europe via WWII reparations.
>> they just don't have enough else in common (beyond their initial emotional attachment) to forge a lasting relationship

This is the fallacy. That somehow there is a magical formula that determines "compatibility". I'm of the opinion that nearly any two people, put together, should be capable of making a lifelong relationship work. Outside of one of the people being completely hopeless, such that they would be incapable of ever maintaining any meaningful relationship.

The way you get to grow old with a partner is obtained by the very simple means of having a committed partner. And therein lies the secret sauce. You don't look for the "perfect match". You match with anyone willing to have a go at life together, and you ride out the long and hard journey. The way to win is to realize that life is mostly made up of shit circumstances, and that life is too short to be lonely. You're better off having someone, anyone, rather than having nobody.
As long as I can have multiple clients working on the same set of files, I don't care how it's implemented. :-)
Committing to sticking through things doesn't automatically mean there's no pain, or that the pain experienced by staying together won't exceed the pain of ending the relationship. The idea that marriage is for life is just a social and religious idea, and then a fairly recent one. There's no natural law that states that it is, or even should be, for life. If you're not happy in a relationship, whatever its stage, and have little belief that anything can be done to make you happy, then end it. Not saying it's easy, but I daresay it'll be worthwhile in the long run.
For this kind of tool that doesn't seem such a big problem. The presentation screenshots could have done without the Motif theme, though :)
It's probably off-topic and I'd hate to derail the discussion, but could you outline what you mean with a "Day 2 company"?

Techops at WMF here: the TL;DR is "no", but I can get into details.

MediaWiki accounts for the lion's share of the servers we run (between MW itself and the databases and the object storage for files/images, I think around 60%), but it's not really that inefficient, also because we aggressively cache content on our own CDN.

Given the amount of traffic we handle, I don't think any sgnificant change could reduce the hosting burden much - and it's already a very small footprint at 2M/year. To give you some context, we have currently less than 2000 physical nodes across all of our datacenters; it's pretty hard to reduce that number further while guaranteeing stability and performance of the sites.

I'm not saying we couldn't improve things - there is always room for it - but I doubt we could do something that reduces our hardware footprint by a significant amount. As a benchmark, moving from PHP 5.x to HHVM gave us more capacity and over two years we reduced by 15% the number of MediaWiki application servers, but that does not result in a huge change in the hosting bill.
Ask HN: How to Transition from Buildings Engineering to Software Development?
I've been working for a large engineering consulting company for the past 4 years as a graduate and I'm looking to jump to software engineering or similar.

I have degrees in Aerospace Engineering and Mathematical and Computer Science, majoring in statistics and applied maths. I'm proficient in Python and Java, I've worked on a number of smaller side projects.

The biggest obstacle for me is finding an entry level job that accepts non-recent graduates. I've been knocked back by a number of companies for not being a recent (<2yr) graduate.

Does HN have any advice?
Is it really ? I have multiplied my income by 10 in the last two years and it hasn't made a huge difference in my lifestyle. I can afford nicer versions of everything, but the improvement is marginal. Like going from pressing my own fruit to pushing a button on a Juicero.

since it is played on a fixed display it was essentially tracking the direction of gaze in that setup, from the POV of gameplay I don't see much difference between that and true eye tracking.

Absolutely not. Head and eye movements might complement each other, but they are completely different in execution. And you can't reliably track gaze from head movements alone.

Focusing on distinct objects by looking at them, for example, is something you can only do with eye tracking (except for the most extremely coarse cases where there's only one object in the general direction of the head).

BTW: Head tracking in games is nothing new, TrackIR e.g. has been around and a staple in sim racers for ~15 years now.
In case of files primarily composed of redundant data, making 2 or more copies on the fly would still save a lot of space. Might be also useful for working in mixed SSD+HDD environments where less data would be written to the SSD and the HDD would hold copies of the files for safety.
It goes further than that.

First, that 7% figure is the whole Android (with play services) user base, numbers are pretty different on the dashboard of our general public app.

Secondly, we will start by compiling for O : the supports libraries are only tested for their corresponding compile version. That way we will be able to use new support lib features on all Android versions.

Then, we will target O (probably in the same release of the app). It should be pretty trivial : this is not marshmallow with the new permission system, system level changes in O are manageable.

For clarification, the build script of an android app separates compile version (= binary compatibility) and target version (= you handle the new behaviors of the system like granular permission in M)

By targeting O ASAP we :

- are potentially able to ship some features based on this release, like shortcuts for N. Sure, we are not going to spend a lot of dev time on an O-only feature right now but there are some easy wins. And of course the install base does not stay small for very long.

-are able to detect potential problems before OEMs start launching flagships with that Android version and we get millions of crashes / day.

There is really no good reason to stay behind.
