Ask HN: Animated sequence diagrams that help explain your tech stack better?
I've been looking around for sequence diagram software that's a lot like websequencediagrams.com (a tool that I really like) but that also accommodates the use case where you “visualize” the “movement” of data & request/response between services through simple “animation”. Think of the interaction model of different components in a specific tier of a technology stack (or even across tiers): You're showing the origin of a request, how it gets processed and passed on by a cluster of services that may conform to different architectures/design principles; the diagrams would help a user express parallel processing, asynchronously sending back messages/data, pubsub patterns, latency at each hop, and pretty much most things that could really speed up the distribution and understanding of system-architecture design. A basic animation would be the directional movement of an arrow/beam from service to service. A more elaborate one could be the shading of an entire component in a pulsating color suggesting a specific architecture/design-pattern.

Can we vary the speed of the "beams/arrows"? Sure. "Are we trying to ultimately generate a GIF image that can be circulated thus obviating excessive meetings?" Indeed. "Maybe create an applet that let's you tweak speed and other variables, and simultaneously generate the diagram in real time. THEN you export it to .GIF" That's definitely one way of doing it. "What's the level of abstraction presented here? Are we talking about large system components, or something like design principles that could be influenced by a programming language's runtime environment"? I haven't thought it through yet, but it seems interesting enough to discuss. I would love to hear HN’s opinion on this, and would like to invite anyone to help me build this as an open-source project if you think it's worth your time. Even if you're not interested in helping me, I'd like to hear whether or not you would use something like this.
This. Exactly.

As a resident of a neighboring town not technically on "lockdown", residents nevertheless acted that way. Streets were empty. Businesses closed. It was very very quiet.
This was obviously done by choice, not mandate. Yes, there was some fear driving this, as a police officer a few miles away was killed for being in the wrong place at the wrong time (cop killings do not occur often in the Boston-area suburbs). However, a large motivator was solidarity with other towns on lockdown. We really wanted to give the police every chance they could to catch this guy. The value judgement was made by private business owners and employers to support that effort.
This article is absolute garbage. It is horrendously long, and doesn't come to any startling conclusion whatsoever. It is orth noting that it's also out of date (2011).

Yes, there is quite a few MW style games - but there's lots of others. Counter-Strike and UT haven't gone anywhere. As for the console vs. keyboard debate, PC gaming is still a viable and growing market. You are free to choose whatever interface you want.
Thousands showed up in Dorchester on Monday night to mourn the death of one of their residents.
VC investors have prefer to have their investments close by, yet they tend to rely on the managers they backed and/or picked to lead these ventures, rarely intervening. If the non-interventionist approach is good, and it probably is, then finding and locating ventures all over the planet should result in discovering more talent, and holding down costs.
I'm not big on TL;DRs, but this post is screaming for one.
As digital "piracy" does not, in fact, kill music executives, I think we should stay with analogies a little closer to civil law. There's honest mistakes, then there's neglect, and then there is fraud.

Then there's conspiracy to commit fraud (I guess that is what happens when your lobbyists can't get your scam passed as law, but you try to get your way anyway? ;-)

Does anyone have any ideas about why the browser plugin for applets has so many security zero-days?

If competing products like Flash, JavaScript, or HTML 5 have fewer security issues, what are the engineering reasons they're better, and how can those lessons be ported to Java?

Alternatively, maybe Java applets are actually comparable to other technologies in this space in terms of security zero-days. Its bad reputation might be merely due to the fact that relatively few people actually use it, so a recommendation to get rid of it won't break nearly as much of the Web as removing Flash or disabling JS. Is this explanation plausible?

I suspect the police messed up, and she's looking ahead to the day when she might have to salvage her prosecution because of it. "National security" is just the straw she's grasping at.

And when everything becomes a national security issue, then national security means nothing. But that doesn't matter to one prosecutor trying to notch one more case.

The Boston Marathon is a high profile event, and when explosives are involved, the security response is elevated.
Explosives != pillows.

The "world renowned" aspect is just that. The world is watching how we respond to such incidents, and to attempt to marginalize this incident by comparing a mother smothering her children with pillows to bombs targeting a crowd is callous in the extreme.

Of course we'd prefer to catch all criminals, especially those who target high profile events with explosives.
Still, I think it's too easy to to write off injury statistics as probably not that bad. So, less than 1 in 10 people hospitalized ended up loosing a limb, but I know there was a lot of talk about shrapnel taking "chunks" out of people's legs. Many of the victims may suffer permanent disabilities. One guy lost an eye.

I used to assume that when I heard injury reports after an accident that I could safely round down to a smaller number of 'truly serious' injuries. But I haven't able to think about it the same way after reading an interview with a guy who does forensics in suicide bomber cases. He said something along the lines of "You hear '15 injured', and you think they probably needed stitches or something. But for most of them, 'injured' really means 'fucked for life'"

You mean a particular point of view on "The correct state of being." What if I don't necessarily agree. Am I not free because my POV is not "correct?"
While I think your point about cultural issues causing problems in other areas has truth to it, I think it's funny to call silicon valley the most diverse community in the US.

The valley exists on the doorstep of stanford - an incredibly highly selected (this year the most highly selective) university. In addition to that a large portion of the people I've met here come from fabulously wealthy backgrounds (dynasty money) where failure is largely irrelevant because there is always a near infinite supply of backup money.

I think part of the reason the valley does well is because the population is some of the most homogenous and highly selected in the world all living in the same place and there is enough wealth to try things.

Liquid Helium works through heuristiics. LHe is the symbol for Liquid Helium in science, and is the intitials for Language Heuristics Engine. (we are so clever we know)

http://www.youtube.com/watch?v=9pb_F1mwLCo explains it oversimplified.

Basically we create a very efficient set of classifiers using sieves.

Imagine you want to find a "How To".

What makes a great How To? It should be instructional. Have steps. It shouldn't have a lot of opinion. It should have good descriptions. It should be written as commands in the "you" form.

These are all language constructs we can identify. Then we score a document to see that it meets a minimum requirement to be a "how to".

When you do a search we filter and rank results based on what kind of search we think you were performing. We determine the type of search based on what other people have searched, what kinds of documents come back and we build an "ideal result profile" which we attempt to meet with the documents in our result set.

If you are looking for a review we try to find a balance of positive and negative.

If you are looking for a song we try to find lyrics and videos of that song.

We also summarize each result.

Some of these things happen only after someone has done a search for the first time. So if you are the first person to try a search you may have to wait 30 seconds and try again.

My experience with Microsoft is that they still fundamentally don't understand that everything has changed around them. They believe they are right because they are Microsoft and poor sales, poor reviews and poor stock performance is really just an unfair world set against them. What else could it be? We are Microsoft!

When I tried to engage Microsoft about better supporting indie game developers on Windows Mobile phone, the sense that I got was that XBox was successful brand and that adding Xbox-like services to Windows Phone could jeopardize this brand. How could they offer a free achievement system for indie developers and still justify charging $50K for similar services on Xbox? (source: I'm the creator of mogade.com)

You really get the sense that the comical org-chart representation of MS is accurate:
http://4.bp.blogspot.com/-1OeWV6O5BzM/TmjGWNGlO7I/AAAAAAAAAA...

How does this relate? I'm not surprised to see that the Azure team is attempting this whereas the Windows Phone team never did. It's obvious now, looking back at it, but I should have engaged the Azure team, not the Windows Phone team, for any truly progressive thoughts on mobile development.

I suggest using a Window Manager, such as DWM, instead of a full Desktop Environment like GNOME/KDE/etc.
Surprised? If you look in the iTunes store, MSFT has a number of apps, a number well reviewed. Much of the commentary after MSFT released numbers last week was about the diversity of their offerings -- yes Windows and Office are still the big fish, but diversity can be a good thing.

MS Office for Mac and an investment in Apple when it was in a tough spot show a history for the company having a broader view than just the Windows ecosystem (that's not saying, that isn't the MAIN focus).

Isohunt is the intermediary. If they don't like a takedown notice then they can just not execute it; they don't need any redress from the courts. The plaintiffs with standing should be the end users who posted the material that was removed.

>But they'd be sitting on top of a mountain of potential claims, which would prove lucrative if even a tiny percentage resulted in damages.

Setting aside that Isohunt is the wrong party, yes, there are a mountain of take downs from which some small percentage should result in damages. But you can identify those cases ahead of time -- you know perfectly well you aren't going to win a case where you posted Fast & Furious 6 to Isohunt and Universal Studios issued a take down for it, there is no point in even trying. And if you do try then you're effectively admitting your own liability for copyright infringement when you have to assert you posted that material in order to get standing to sue.

The cases lawyers will want to take are the ones they think they can win -- and as long as they're right, that's what they're supposed to do. That's the whole idea.

Are you arguing that the situations where the take down is in a grey area (e.g. fair use) will create too much litigation? I don't really see that happening. On the one hand, the existence of penalties would create a disincentive for copyright holders to wantonly issue take downs in questionable cases, and if there was no take down then there is nothing to litigate. Then, in the consequently much reduced number of edge cases, in order to claim a take down was fraudulent a plaintiff would have to admit in court to posting the material and thus to liability for copyright infringement if the take down was legitimate.
I know a little birdie or three who would have interesting comments to make on that figure but they wouldn't appreciate the publicity. All of them run real honest-to-God businesses which just happen to resemble a blog in form-factor when you squint a bit.

Incidentally: blogging is still a terrible way to make money for the vast majority of bloggers. The really successful ones generally use it as a friendcatcher for related business. It isn't even the most efficient friendcatcher, either.

> There isn’t yet much written about cognitive overhead in our field

Couldn't disagree more. Cognitive load is a major element of information architecture and even has an explicit representation in flow charts. Any book on information architecture or UX is half about it.

Many if not most decisions in interface design and IA are based on estimating (and reducing) cognitive load - how many options/buttons to present, how deep navigation should go, how to group things, splitting up an action flow in order to reduce the memory/choices needed...

The example given for QR codes is also wrong - "So it’s a barcode? No? ..." - it is a barcode and you need a barcode scanner/app, everyone knows how barcodes work. QR codes are not the best thing around, but IMO they didn't catch on for a lack of interest from manufacturers (no native support), not because it's overly complex.
There are a couple of packages in Haskell that let you do this, including unittyped[1]. It lets you write code like:

*Main> 2 meter + (1 meter / second) * 5 second
7.0 m

A really cute feature is that prefixes like centi and deci are functions:

*Main> gallon `as` (cubic (deci meter))
4.546089999999999 dm⋅dm⋅dm⋅#

It gives you an error if the dimensions don't match, but unfortunately the error messages are hideous.

Anybody can define new units just by giving a conversion factor and a string to display. These new units immediately work with other units. You can probably define new "dimensions" as well, but that's bound to be more involved.

All the units are represented as empty types, so it should have no overhead at runtime.

So it is very nice syntactically, with the only real problem being the error messages and the fact that it uses a whole bunch of extensions and only supports very new versions of GHC. I think it's pretty cool.
I think it's hard to argue that San Francisco is not the major city most open to cultural diversity in the country. The Bay Area is very diverse ethnically. New York perhaps but its economy is dominated by finance which sucks the air out. The Bay Area's openness is key to the success of Silicon Valley. Stanford certainly has a lot of positive influence, sure, but there's more to the Bay Area than Palo Alto.

EDIT: To clarify not just ethnic diversity, but diversity of opinion and openness to all kinds of cultural diversity. For example I see a non-trivial number of non-straight people in startups, and it's pretty easy to argue many parts of the world claiming they want to create a new Silicon Valley are not as embracing as the Bay Area when it comes to sexual identity.
Do you think people would pay to rent mining equipment?

I'm not sure how the pricing model would work, but it would allow more people to contribute that can't afford to spend thousands upfront. Maybe some sort of pooling of funds, buy equipment, split profits.
So wrong answers (assuming they're wrong) and speculation are now speech that can legally be suppressed? You can't say anything that's wrong or a guess?

> Congress is a black box to us. I've read the text of CISPA, and I don't think it's unreasonable, but you have to trust the people using it, and we don't. That pretty much ends the conversation.

Then you're totally and utterly screwed. Ordered civilization is built on trusting our civil institutions. Not necessarily individual people, but the institutions as a whole. Once that trust is evaporated, the civilization is done for. You become Bangladesh instead of America.

I don't think we're there yet. I think the impression is built more on fearing what you don't understand. But if you think we are there, that you can't trust our institutions in their capacity as institutions, then it's time to move because there is no coming back from that.
I can't speak for the parent, but this is my reasoning: They make close to a hundred billion dollars a year by selling hardware, so they don't need to sell my private information for some quick cash.

It's stupid, I know. But the same couldn't be said about advertising-driven companies (like Google and Facebook).

In other words, being mindful of user privacy is a luxury they can have right now, and it's good for their business (i.e., they're not doing it because they're "good", or others that do are "bad" or "evil" - it's just that they're now in a position that respecting user privacy is better for their bottom line than not being respectful)
