There are loads of possible ways to increase sensitivity, but none of them are easy or cheap given that the low hanging fruit was all picked off in previous generation detectors.

Increasing arm length is the "easiest" but definitely the most expensive option. Try finding a 40km L-shaped area that's seismically stable and free from significant anthropogenic activity. There may only be a handful of places in North America. However, 4km is already on the cusp of being long enough that gravity misaligns the two mirrors are each end of each arm due to the curvature of the Earth. Going to 40km would prompt the need for static corrections to mirror alignment, which will increase the amount of seismic noise that couples into the longitudinal direction in which gravitational waves are sensed. There are other problems such as the need to either refocus light at points along the arms (very susceptible to alignment and thermal noise) or use much, much bigger mirrors. The Advanced LIGO mirrors are already ~40kg, ~30 x 15cm cylinders of the purest fused silica known to man circa ~2012. There is talk of increasing the mirrors to 200kg and ~50 x 25 cm, and no facility is currently capable of producing pure enough fused silica at that size.

An "easier" option is to increase the laser power. This gives diminishing returns, and leads to an increase in high frequency sensitivity at the expense of low frequency sensitivity (due to photon pressure pushing the mirrors around noisily). However, the challenges are to make stable lasers that are also powerful - very tricky - and to mitigate the effect that laser absorption has on the mirrors within the interferometer - as you increase laser power, things heat up. Hot mirrors can lens the light, misaligning it and creating extra loss (i.e. reducing sensitivity). It's trickly to mitigate. Another effect of higher laser power is the introduction of parametric instabilities, where the mechanical body modes of the mirrors are amplified by the high laser power, leading to huge spikes of noise at narrow frequencies which are difficult to damp out.

Another is to use a different interferometer topology: instead of an L-shaped Michelson interferometer, suggestions have been made for Sagnac interferometers which possess an interesting property called quantum non-demolition, which can potentially reduce the limiting noise source in Advanced LIGO which directly increases sensitivity. Research into this is at a very early stage and will not be seen in detector facilities for decades, if ever.

So, the short answer is: there are lots of potential methods to increase sensitivity, but all of them are challenging and require significant R&D and money.

A clue that could tell the non-tech-savy audience that something was off with Vista was its laughable "wow" advertisement campaign: invariably depicting a starry-eyed person looking at an unseen and undescribed thing off-screen, and expressing "wow". No product features. No aesthetics. Basically just an industrial ad with a soundtrack. The only thing that was crystal-clear was the subtext: "we have no idea why we're selling this thing so we'll just say wow".

I think this book is better suited to people that have already written a few games.

It mostly talks about common patterns that arise during gamedev and how to work with them. IIRC, it shows trade-offs of different approaches.

I suggest starting out with Love2d [1]. Docs are good, community is great, lots of tutorials online.

There's this guy writing a tutorial series [2] on creating a game with Love2D. Not finished yet, but it is awesome! I think that would be a good place to start.

I hope this helps.

I agree per capita/ per country is not the best way. Ultimately it comes to each individual don't you think ? . What does each every one of us directly or indirectly contribute . Any other grouping like country is always going to be arbitrary.. we need to each individually, in local, regional, national government, vote for the people who care and do the best we can irrespective what any one is doing or not. We need make them reduce too yes, but getting our shit together should be the priority

You are correct environment is not reason we should be worried . it is about the people, not the planet. 99% of the all species are already extinct one more large scale extinction event while terrible is not the end of life on this planet and the planet has seen far worse, life will survive long after we are gone. Sea level raise will adversely 60 % of the human population who live in the coast many of whom are poor. Changing weather patterns and climate change will affect the developing countries far more than first world countries who will have the resources to manage the effects . There are whole island countries that will disappear within the turn of the century. This is why developing countries are in very touch spot, they will need to balance both development of basic services and also find a meaningful solution to the problem.
Cool, I realized you could get 4 not just 2 faces to 7 with summitry. And you could increase the interior volumes if the three bases of the triangular pyramid extending to the edge of the cube. But, I had yet to work out you could get five volumes on the final two sides that way.
The power (energy per unit time) emitted in the creation of gravitational waves by the source observed by LIGO was briefly greater than the light power emitted by all of the stars in the known universe. Basically, if the gravitational waves were in fact light (they're not), then they would have briefly outshone everything else in the universe put together.
Our grant application was leaked to a competitor, who is now planning to sue
A bit of background first: we are a young startup who has started getting visibility and traction in a small but very competitive market. In an effort to expand towards a new direction, we applied for a government R&D grant which, somehow, found its way to one of our competitors. As of now, it is unclear how this happened. The most likely scenario is that a founder of the competitor company was selected as the reviewer for our grant application.

As you can imagine, this document contains extremely sensitive information on our technology, market, collaborations and our future plans. Even worse, we have been informed that the company is intending to sue for patent infringement. Now, we are fairly certain that the claims of patent infringement are bogus. The real danger is that engaging a legal battle would drain our resources in a way we can ill afford right now - and our competitor knows it.

At this point, I would like to ask the HackerNews community for your advice and experience. Have you ever encountered such a situation before? How did you react? Any specific do's/don'ts we should keep in mind throughout this process?

My heartfelt thanks for reading this. It's one thing to read about horror stories of legal battles, but it's quite another to have one of them happening to you.

has always been code completion.

I disagree. Code completion is overrated and only of marginal importance in the production of high-quality code. The key advantages of types are:

- Enabling ahead-of-time compilation resulting in efficient code.

- Guarantees on	the absence of specific	classes	of bugs. (This requires soundness.)

- Aiding verification. Types provide a rough classification of program behaviour which drastically simplifies verification. If you don't have types, your program logic needs to make typing information explicit in assertions.
Very early android (I bought 2 G1's the first day they were available) there weren't many apps. One popular app would show you where you were, where the tower you were connected to was, a bunch of related metadata, and a link to the FCC database for the tower. Not sure if that data is still available though.

Seaglass seems like basically the same thing, but they track the metadata across carriers, cities, and of course over time. That way they can track changes in the tower, unusual towers, or unusual signal strengths.

GNU Bash segfaults for me whenever I type ~[tab]. Thankfully this only happens on the small few systems I had to manually patch after the epic Bash vulnerability a couple of years ago - older internal systems that are still in use for historic reasons rather than regularly relied upon in production. So it's never been annoying enough to fix.
The quotes are what other people have said. Jokes need to have a punchline and evoke a humour response in the audience; the references to base-1 in the ancestor comments do neither, so describing them as a 'joke' is inaccurate (hence the quotes to mark it as verbatim).

I certainly agree that overuse of quotes makes a comment pretentious!
> The kernel really needs to provide new syscalls for these features that operate at the process / thread-group level.

Or it could provide another clone flag that indicates that threads spawned that way should share privileges and similar things, then runtimes that need threads to all behave the same way can opt into that. I suspect that some tools do advanced privilege kung-fu that relies on those per-thread properties.
No filtering is applied to data containing such anthropogenic/geological noise after it is measured to remove such effects. In fact, such data is usually junked and not used for analysis. The sites have thousands of witness channels which listen for things like trucks, ground motion, magnetic storms, etc. that could possibly influence the mirrors in the way a gravitational wave would. If the same signal appears in both the gravitational wave channel and some auxiliary sensor, it's thrown away.

Instead, the mirrors are highly isolated from the ground (suspended from pendulums, motion damped by actuators, that sort of thing) so that such effects do not have significant impact on the motion of the mirrors.

In any case, seismic noise can't be fully isolated and creates a sensitivity wall below around 10Hz. To get sensitivity much below 10Hz, you have to go to space (look up LISA).

Well, banks have tremendous restrictions on what they can do, in collusion, or unilaterally.

One very good reason for this high level of regulation is that banks are a primary component of the money supply system. Having a functional monetary system is a great thing, for the society as a whole.

It has aspects of being a public good. (Some people argue that banking should be made a government supplied service, for this reason.)

Almost every aspect of modern life is subject to laws and regulations, by a sovereign entity of some sort.

Such an entity has very valid reasons for regulating the use of bitcoin.

The "core developers" not only deserves to be attacked but should face fraud, DDoS and CFAA indictments for criminally handcappig and limiting bitcoin while pushing for SegWit, a proposal that discounts smart contracts they write (Lightning, Sidechains) by 75% while engaging in astrosurfing, censorship, DDoS attacks against those who actually want bitcoin to prevail instead of becoming Blockstream's pet project.

Blockstream, armed with venture funding tried (and is still trying) to "embrace, extend, extinguish" bitcoin to their own "open in name only" system. Just look at their attacks (including DDoS attacks against nodes, and reckless security disclosure motivated by sabotage) against Bitcoin XT, Classic, and Unlimited.

Dissecting Marissa Mayer’s Yahoo Compensation
Great book. I recommend buying a paper/ebook version to support the author. His writing style is very concise and funny so it's easy to follow and it reads very fast. The only thing I didn't like is that for code examples he uses C++ with unnecessary classes where vanilla C functions would've been sufficient, but I understand his reasoning for doing so ("It is the lingua franca of the industry").

Does anyone have any recommendations for other books about game engine design?

> You don't understand why someone would complain that a mega-rich corporation is increasing its own wealth by refusing to pay a living wage, which then requires everyone else - not profiting on this person's labor - to make up the difference?

It seems like you've completely failed to understand any of my comment. I'm taking issue with the entire construction of the claim you're making. If I buy a guy's used car from him on Craigslist, and he doesn't have a job and that was his only income that year, am I "increasing my own wealth by refusing to pay him enough to live, which then requires everyone else to make up the difference"? No, and your claim makes as little sense as that one does.

My whole point is that I've never heard an argument for loading the purchase of labor with the responsibility for arbitrary parts of the seller's life. The only arguments I've ever heard in support of it (like yours) are just a poor excuse to shrug off the responsibility that society owes to its citizens.

> The only other alternative would be to drastically increase social services and tax people - like the Waltons - a LOT more.

Well _duh_. That's entirely my point. And it makes infinitely more sense to target governmental revenue intentionally (ie through a progressive tax code) than to resort to the current messy workaround and all the distortions of the labor market that it implies.
About leaving (a startup, a role, a team)
If you are sued, then post details here (it is public then) and the community may be able to assist. Adding to your patent portfolio as a defence is also a good idea. Your enemy is also going to do this.
You can also sue because the grant process that involves external reviewers probably makes these reviewers sign an NDA. This competing company may be fraudulently volunteering to review cases to get advance warning of up and coming competitors - more chicanery.

In my case it was initially just being extremely dissatisfied with my life and deciding to do a startup. Which is kind of like realizing your car is out of gas and deciding to push it across the desert for fun.

Eventually I found something which grew into pure unwavering passion. Unfortunately that doesn't automatically translate into being able to execute successfully.

The other reason was a desire for massive amounts of wealth. Not for the sake of it, but because I'd love to be able to spin up large projects left and right. Paraphrasing another comment: the deep desire to do things better. And of course, make the world a better place.™

Funny enough, I spent about an hour writing a fairly heartfelt ten paragraph reply to this question, until Firefox mobile crashed and lost it all.

Then I realized that reply was an explanation of what keeps me going, not what motivated the decision to start in the first place.

It's a psychological minefield: career and personal life opportunity cost, sunk cost fallacy, people depending on you. Much more messy than the simple why of starting.
