Communications of the ACM has changed a lot over the last few years. They're trying to make it a lot more relevant and also raise the impact. This means that the Practitioners section is now managed by the team behind ACM Queue and contains stuff that people doing exciting things in industry are doing and the rest has a higher standard of peer review. The Research Highlights section often points to papers that I want to read. Most of the top-tier conferences and journals for computer science are ACM-sponsored.

... where your data disappears and your apps stop working the moment the company goes under.


Last night I went to a panel in SF on the "House of the Future", which all participants interpreted to mean "hooking your appliances up to the Cloud for access via phone apps". When your cloud-based home control provider goes bust, (or just discontinues the "obsolete" interface your devices used) your gadgets will stop working.

People with cloud-based garage door openers, you have been warned.

Fabrication costs eat you alive if you try to approximate a fractal too closely; but that is essentially where the later generations of solid metal heatsinks were heading before heatpipes hit the scene.

In the cheapest and simplest incarnation is just a beefy heat spreader plate on the bottom to ensure that each fin gets a reasonable connection to the heat source. In fancier versions, the spreader also extends vertically to help transfer heat to the more distant parts of the fins.

Recent AMD retail heatsinks use a clever design (cheap, because it's an aluminum extrusion with just a couple of cuts for the retention clip; but a combination of fins for surface area and bulkier conductive struts to feed the fins): image. The central slug is about the same size as the CPU heat spreader, and is solid throughout except for the slits for the retention clip. The longest fins are the ones directly attached to it. The four thicker struts on each corner support shorter fins(longer close to the base, shortest at the edges where there will be the least heat available for dissipation).

Heatpipes are superior enough to just about any solid material(with the possible exception of diamonds and carbon nanotubes; but those aren't really options) that most of the more expensive coolers have moved to 'heatpipes as close to the CPU as possible, loads of sheet metal fins with the heatpipes running through them' design; but you can definitely see the tradeoffs between surface area and conductive cross section in today's cheaper extrusion designs and the last generation or two of pre-heatpipe enthusiast gear.

The ACM is pretty good about open access. Every author can use their 'author-izer' service to create links that check the referrer but give free access to the papers, so if you can't get free access to an ACM-published paper from the author's web site, then complain to them, not to the ACM.

Yeah, lets compare a 40 year old monopoly company (making money w large contracts) to a bunch of small upstart developers (making money $0.99 at a time) and laugh.

Let's not. Let's compare the mobile app market to one company. The mobile app market has a number of small upstart developers making $0.99 at a time, but it also includes companies like IBM, Microsoft, Apple, Adobe, and a large number of software houses that are 20-40 years old, several of which have been on the receiving end of antitrust lawsuits.

is the electron ACTUALLY doing that, or was that simply a mathematical/logical proof that correlates highly with what we see?

Ummm. physics has been all about testing for discrepancies between the two for at least a century now. There's a nobel prize waiting for anyone who can show an electron not behaving itself in accordance with the standard model.

This is, unfortunately, the case with a number of funding bodies in academia. For example, DARPA won't pay for my membership, but will pay for the conference. My institution decided to pay for membership out of a different pot of money that doesn't have these restrictions, which ends up with a saving of a few hundred dollars on one account and a cost of a hundred dollars on another.

Ah, you're in the USA? Here, most people have pre-pay plans (being locked into a contract is generally seen as negative, unless it comes with some really good deals) and so get the phone that they bought along with their SIM and then hang onto it until it breaks or someone gives them a new one. I don't think I know anyone who pays close to $40/month on a phone bill (a fifth to a tenth of that is common and it's hard for a contract that comes with a new phone to be that cheap). At that price, I'd probably do without a mobile.

Amazon's app store is a bit better, because they're good at correlating things you've bought with things you might want to buy, so have recommendations that don't totally suck. The only reason I actually have it installed though is their free app of the day (which isn't necessarily a good thing - there are a couple of games that it's given me that have wasted a lot of my time...)

$13b is a big-sounding number. But it's not that big in comparison to some other numbers. For example, there were 75b downloads from the Apple App Store last month, so even if that $13b were just for the last month, not for the lifetime of the App Store, it would amount to less than 20 for each download. There are 1.2m apps available, so $13b means just over $10K per app. That's quite a lot for a week's work, but it's a pittance compared to the cost of developing a typical program, especially when you consider the earnings per year.

Oh, and for reference, Microsoft's revenue for the last quarter was about $20b. Which makes $13b spread between 1.2m apps seem very, very small. (I'm assuming that your $13b number is just for developers selling through the Apple App Store. If it also includes Android then it's an even more laughable number).

Finally, I never see ACM articles linked from Google. You'd imagine searches for things like "reduction of inter block artifacts in discrete wavelet transforms" should nail 5 ACM articles on the first page. Instead, I see mailing lists.

They'll show up if you use Google Scholar. If you're using the main search engine to find papers, then you're probably doing it wrong...

There is as an academic. Apparently being a member of the ACM has a negative value, because in exchange for the $99/year membership fee I typically get a $100-150 discount on attending ACM conferences. If you go to a couple of conferences a year then that's a good deal. For people outside academia, there's less relevance. ACM Queue, which provides material for 'practitioners' section of Communications of the ACM, generally has some good material, but it's all free whether your an ACM member or not.

I like the ACM as an organisation, but they're hard pressed to justify the cost of membership.

"One Architecture, One OS" also translates as "One Egg, One Basket".
