1 Gbit/sec, if you look at the Jupiter paper, was the host speed in 2004. The Jupiter system works with 10G and 40G interfaces on the host.

What's important to recognize is you simply cannot buy Infiniband switches that let you contact a lot (10K+) of hosts together. The vendors won't sell you this, they won't do the R&D to make it, and it would cost infinite anyway.

This is a deliberate choice: for most Internet work, it's better to have really fat bisection bandwidth and non-blocking fabrics, and latency is ignored due to the high cost of building a crossbar that supports that with high radix.

Only if you have an algorithm that absolutely requires, and simply cannot be fixed, low latency, you are almost always better off building a cheaper, fatter fabric, and hiring engineers who know how to write applications that are latency tolerant.
It makes a great deal of sense to stress about it when you have a lot of long-term debt used to purchase your real estate assets, and have some control over the lease terms you offer. If you think the end of the boom part of the cycle is 6 months away, you want to lock people into the longest-term leases possible, so that they expire when the market is again, if not strong, at least not weak. If you think the end of the boom part of the cycle is 4 years away, you want to offer the shortest-term leases the tenant will accept, because they will then be forced to renew at a higher rate.

This is very similar to the dry-bulk market. It should be instructive to look at how companies like DryShips and Diana Shipping handled the enormous spike in the Baltic Dry Index several years ago, how they've fared since, and how they've managed their businesses afterward. The cyclical nature of markets cannot necessarily be controlled, but it can be harnessed to outperform one's peers, and if you are a REIT portfolio manager or smaller property manager, your job depends on doing just that.

Didn't they actually try to slow people down from upgrading release day? I mean what I read everywhere is that (paraphrasing), "when windows 10 is ready on your PC you'll see a pop up, but register now."

Then you could just go and force the upgrade if you are impatient (like me).

A non-trivial portion of Clojure (data structures, compiler) are written in Java. In ClojureScript these are written in Clojure or ClojureScript so there's really not as much to share as it would seem.
This keeps getting mentioned in various places, but it's nonsense. We're talking about a tiny number of obscure Java programs which do the insane thing of checking OS version by string rather than with numbers.

For the five people on Earth actually affected by this, there's always compatibility mode.
That book is such a masterpiece of technical writing I've recommended it to people who don't even own VWs. It deserves to be recognized in the same discussions as The C Programming Language, Advanced Programming in the UNIX Environment, and the 1st ed. of Tcl and the Tk Toolkit.

I'm not a big fan of reddit. But I would realistically be willing to pay for ad-free communities. I used to be an Imgur Pro member before they stopped accepting payments. I would gladly become one again.

They charged $3 a month or $24 a year. Considering I pay Amazon $80 a year for a service I barely use, I should be willing to pay a community about that much.
Yeah, both. In fairness, the last time I tried using the API was before the libav split, and I have no doubt that the situation has improved; the command line, while almost ludicrously powerful, retains a lot of terrible habits -- silent defaults, mutually contradictory options, &c.

I have somewhere a much more prescriptive python library that sits on top of the command line API, but I think it'd be really great if there were a "strict" mode for the CLI -- no more implicits, no more silent rejiggering of options. If you don't totally account for your input and output, it's an error. Then, there could be a much more forgiving and intelligent front end to the front end that allowed for things like "-i foo.avi ./foo.mp4", making best guesses at each stage of the pipeline.

Why does everyone complain about error reporting?

A former coworker of mine worked with one of the areas in Microsoft that dealt with error reporting. They actually analyze the data and provide feedback to the vendors of crash-happy programs. It's an important thing that helps generally improve quality of life.
I would think by now everybody knew that you had to wait at least one year before adopting a new Microsoft OS. OK, with the "new Microsoft"* you can probably shorten the delay to 6 months, but any shorter than that you're an early adopter and shouldn't complain.

I'd include the point releases in that. XP once it was patched was awesome, but I recall nothing but problems prior to SP1-2. There's also 8.1, which fixed a lot of people's W8 complaints.
Almost all of the author's complaints revolve around the Control Panel. Most users won't ever see the Control Panel, just the Settings app.

The Control Panel is a legacy piece they decided to keep around for the "enterprise"; just like Windows 10 also still includes the old Internet Explorer.
Did you evaluate Vulcand (https://github.com/mailgun/vulcand) and if so what were your thoughts? It sounds like Baker Street eliminates the spof. I've only used it to get a feel of it, never in production.
Don't both have their places? There are benefits to having a power source that is a) not dependent on a resource that is not available at all times and b) does not require a charging period.

It's sort of like people in the late 19th century saying you shouldn't support the development of automobiles, because boats are much more efficient way to move cargo. While true, it does nothing to address the fact that in some cases the use of a boat makes no sense, such as transporting to a land-locked location.
Thanks for the update! I really like your novel approach. Ray marching is pretty cool for scaling in procedural generated graphics so that you don't have to load entire geometries and cull most of it. Just render what you can see! :)

Nice trick with the objects.
Yes, it's fixed in SVN, supposedly.
What a nonsensical attitude. Ostensibly, any "bashing Windows for UI/Updates/Privacy/whatever reasons" (which is an extremely odd way to say "criticism of Windows") is now equivalent to a Slashdot polemic?

Programming is the only technical field I know where this anti-intellectual sentiment of shutting off criticism and resorting to slogans like "If you don't like it, don't use it!" and "I don't care about X, it works for me!" is somehow considered acceptable.

I have very mixed emotions about this. There were certainly some non-major-specific courses that I had to take that did have a positive effect on my thinking and reasoning ability. The majority, however, were a giant waste of time and money, and I still resent being forced to take them. May be just as much a reflection on my alma mater as on me.
Glad to hear you are happy with GitLab! If I'm not mistaken all three options on https://about.gitlab.com/applications/#scrum-boards offer a SaaS version, so you wouldn't have to self host it.
> weights dangling around at variable points between ceiling and floor sounds if anything even more of a liability than a lamp with a naked flame, which does at least stay where its put.

Fire stays where it's put? No. The problems with flames involve toxic gasses poisoning people and the occasional building on fire. That's really not consistent with the idea that "flame stays where its put"
Apple's obviously not just letting the technical debt pile up. They've put a lot of effort in to addressing it in a lot of areas. Some of it hasn't resulted in a usable replacement (ZFS, discoveryd), but other areas have been modernized (LLVM, launchd, Core whatever frameworks, Gatekeeper).
The node constructs the path it uses. As concentration in one area becomes a concern, those nodes can be identified as Amazon based on IP so clients know not to use more than 1 or 2 nodes there.

Part of me loves speculation like this, but the other part of me wonders if the speculators are aware that Tolkien (and authors in general) is/are "just another imperfect human".

Did Tolkien think of any of this? It's his world. Speculators creating their own fantasy around it aren't really speculating, but making up their own version.

It's like the "nerd at star trek convention" finding plot holes. The reality is a staff room filled with writers working under deadlines and restrictions. However there seem to be people who want/need (and speculate) that every possible detail can/should be nailed down into something that makes absolute sense.

Maybe someone just wasn't very creative one day, or wanted to move onto a bigger plot point.

Anyway, this is just one dude's (me) point of view, maybe the speculators are more imaginative and better at life, and I'm just a cynical old man.
I do in fact enjoy sleeping immensely. As alluded to in the post while I tend to do a lot of "driving" - this release was the result of a broader effort by the growing Clojure & ClojureScript communities.

They've been saying that from the begining. There are no real technical constraints, it's been done in all kinds of languages and it has been a well understood feature for 2+ decades. They just don't want to do the compromises needed, while letting the developers continue to deal with all of them...

Oh yea. Try this.

echo "found one";

}

}

Surprise! Never prints "found one".

> There are some realities of actually owning/running a business that are hard to understand if you have not done it before. ...

Having done it I don't agree. It's a widely used cover story, 'you can't understand X because you haven't done it', a way to avoid accountability or having to make a reasoned argument. We all have directly experienced only a tiny fraction of the world, yet we use our cognitive abilities to understand much more.

I also disagree with your view on taxes and regulation. Our taxes should be higher, certainly more fair (the wealthy sacrifice much less than poorer Americans), and some industries need much stronger regulation, including Wall Street and the medical industries. Finally, government, being a human institution, is flawed; but I have yet to see a business (over a certain size) that doesn't waste money, experience corruption and incompetence, etc. It's a weak argument to simply dismiss serious issues with the unsupported meme that government is somehow relatively incompetent.

Of course many agree with you. Some have good arguments, some are merely self-interested (who wants to pay more or have to follow rules?), many merely parrot what the read in the WSJ. You can identify the latter by the consistent use of the same talking points.

Finally, the condescension is unnecessary. If you have a good argument, people will be pursuaded. The condescension brands everything else you say as part of the same rant, not to be taken seriously.
Yeah, I was riffing on the idea of finding a favorable municipality for business reasons and actually running your company where you actually want to run it.

Although given the history of this sort of thing, I guess it'd be more appropriate to call it the Maryland Shuffle.
The .LY ccTLD is particularly problematic because many countries, including the US, have trade sanctions in place against Libya. Among other things, this makes it difficult to get an SSL certificate for a .ly domain.

I think the exact position of the dumping matters though. Unless the ocean is well mixed, the concentration will not be uniformly distributed. For instance, the entire stream might stay integrated as it travels along deep ocean currents (not saying that's actually the case by any means).

Welcome to toll roads. We've been doing this for 2,500 years. Take route A and get your employer to reimburse you. Or, find a new job that isn't going to fire you for taking route B. Or, pay someone else (the government) to get the "mugger" off of route A. Your analogies belie reality. These are choices made every day by millions of Americans. Very few people consider this theft. They'll bitch and moan and play NIMBY games, but I don't see people revolting over these "thefts".

I don't know where rights derive from, nor am I really interested in figuring that out in a discussion regarding rent control. I am a utilitarian, but I am also a firm believer that a completely free market can create inequality that is untenable in the long-term. Rent control in its current NYC might not be the answer, but, in general, housing programs ensure that all people in a relatively rich society (USA) have one of their basic needs met. People that don't have their basic needs met, whether those needs are met through their own action or through cooperation with others, tend to get violent.

To be equally extreme as you: please don't call the non-existent police when "the poors" storm your mansion due to their sub-par housing conditions, fifty years after the "theft" of rent control ends in your utopia.

I'd hate to be Uber right now. The early innovators always bear the full cost of discovery and paving the way for future entrants who will gladly waltz right in once Uber establishes itself in cities by lobbying and fighting regulation. The barrier to entry is not as high they make it seem and like Groupon, a focus on future potential earnings without facing realities, almost always ends up in favor of late market entrants. I recall Peter Thiel talking about this in more detail how you should never be the first at anything and that if you can't build a monopoly you will face the same fate that other first movers have met.

I had the same reaction, and I have severe reservations about availability-focused service location. The potential of firing traffic at the wrong nodes and having it dropped on the floor is a real red flag for me. A failure of a directory service due to a lack of consistency allows an application to, if not trivially, at least reliably cache requests to be pushed later when the health of the overall architecture can be established.

Seems odd that the CDC is so involved with gun violence. This seems to be a better fit for the ATF or some similarly-focused organization.

Also:

> Rivara and his team discovered that having a gun in the home is associated with a threefold increase in the risk of a homicide

Does this account for other factors (such as gun ownership correlating with an existing risk of violent crime)? Many Americans own guns to defend themselves, their families, and their property; it would seem like the elevated risk of homicide is the reason why guns are owned, rather than the other way around. Or perhaps it's a feedback loop. The article doesn't seem to go into much detail here about other possible factors.

> but the RAM usage has gone up when compared to 8.1. On a device with just 2 GB of RAM, this matters, but not nearly as much as what’s coming next…

In that entire article, increased RAM usage was the only thing that piqued my interest. The rest of the issues were styling inconsistencies and changes to how some settings are accessed, both of which are problems Windows has had since Vista.

At the same time, though, it's impressive that a modern operating system can operate on just 2GB of RAM. The last time I had that little RAM, I was running Windows 98.
All of the supposed reasons given in that post have been answered to death by multiple people (including PL experts), and none holds to much scrutiny.

I love this! It's a great way to 'not-stop' students' creativity and imagination. My college doesn't promote much of startup and new creative ideas. They're more focused on getting jobs and getting good salary packages from campus interviews. One of my professors literally asked me to focus on getting more marks and stop thinking of new ideas and startups till I complete college - not all professors help their students' in developing their ideas or startups. A student like me would definitely love this kind of college! :D
A lot of this is the context... You're not trying to prove something is mathematically perfect. You're trying to figure out if the variation is common cause [0] or a special cause. It's ok if you get this wrong from time to time because it's decision support, and it's better to act on imperfect information than to wait too long for perfection.

[0] https://en.wikipedia.org/wiki/Common_cause_and_special_cause... Common causes are addressed by fixing the system as a whole, while special causes are addressed by fixing one-offs. For example if you are addressing variations in delivery times, you address small delivery variance by improving the maps, which help every delivery. You address the one-off variation by firing the guy who takes 3 hour lunches mid-delivery every few weeks.
Your client constructs the whole path. You can take whatever route you desire.

Ask HN: Would you use a stable (1.0) fork of CocoaPods?
Recently the CocoaPods team has been working on a bunch of interesting but arguably unnecessary features (depending on your viewpoint.) Unfortunately, these new features have been causing a lot of breakage: in particular, chmodding the `Pods` directory, phoning home stats about used pods, and trying to keep UUIDs in the xcworkspace file stable have introduced some oft-reported crashers.

The project is getting fairly well-established to break with every new release, particularly when teams rely on it for builds. If you use CocoaPods, would you be happier with a stable fork with the current feature set frozen and only bugfixes from here out? Trying to gauge interest and whether this is pain unique to us or felt everywhere.
