An Algorithm to End the Lines for Ice at Burning Man

Posted by timothy in Science • View
Any gathering of 65,000 people in the dessert is going to require some major infrastructure to maintain health and sanity. At Burning Man, some of that infrastructure is devoted to a supply chain for ice. Writes Bennett Haselton, The lines for ice bags at Burning Man could be cut from an hour long at peak times, to about five minutes, by making one small... Well, read the description below of how they do things now, and see if the same suggested change occurs to you. I'm curious whether it's the kind of idea that is more obvious to students of computer science who think algorithmically, or if it's something that could occur to anyone. Read on for the rest; Bennett's idea for better triage may bring to mind a lot of other queuing situations and ways that time spent waiting in line could be more efficiently employed.

Agner Krarup Erlang - The telephone in 1909!

By SirDrinksAlot • Score: 5, Informative • Thread

A guy named Agner Erlang solved most of this already, and we can thank the telephone. He took his work on how to figure out the optimal number of trunk lines for a town and used that to model cash register lines. Erlang worked out that one line into many registers is the fastest and most efficient, so if one line backs up but another one moves quickly, people don't bunch up at the register that was slow. You can see this system at work at Walmart of all places, their express checkout section where they tell you what register to go to is based on this model. If there's a bottleneck beyond the register, say the ice truck, then have a second queue where individuals are provided with something like a receipt for them to obtain the ice directly from the truck. This also has the benefit of individuals being able to buy more than one bag of ice and can come back and enter the ice truck queue to fill the remainder of the order later rather than requeue in the register line. Obviously there are risks to that but ultimately the risk would be the consumers. Both of these methods are in use today and even at the same time in some cases, I saw it just last summer at a beer festival. We went through one queue to get beer tokens, and then there were multiple vendors who accepted those tokens for you to redeem it. Then the vendors redeemed their tokens from the festival operators.

Developers, IT Still Racking Up (Mostly) High Salaries

Posted by timothy in Developers • View
Nerval's Lobster (2598977) writes Software development and IT remain common jobs among those in the higher brackets, although not the topmost one, according to a new study (with graph) commissioned by NPR. Among those earning between $58,000 and $72,000, IT was the sixth-most-popular job, while software developers came in tenth place. In the next bracket up (earning between $72,000 and $103,000), IT rose to third, with software development just behind in fourth place. As incomes increased another level ($103,000 to $207,000), software developers did even better, coming in second behind managers, although IT dropped off the list entirely. In the top percentile ($207,000 and above), neither software developers nor IT staff managed to place; this is a segment chiefly occupied by physicians (in first place), managers, chief executives, lawyers, and salespeople who are really good at their jobs. In other words, it seems like a good time to be in IT, provided you have a particular skillset. If those high salaries are in Silicon Valley or New York, though, they might not seem as high as half the same rate would in Omaha, or Houston, or Raleigh.

Google Changes 'To Fight Piracy' By Highlighting Legal Sites

mrspoonsi writes Google has announced changes to its search engine in an attempt to curb online piracy. The company has long been criticised for enabling people to find sites to download entertainment illegally. The entertainment industry has argued that illegal sites should be "demoted" in search results. The new measures, mostly welcomed by music trade group the BPI, will instead point users towards legal alternatives such as Spotify and Google Play. Google will now list these legal services in a box at the top of the search results, as well as in a box on the right-hand side of the page. Crucially, however, these will be adverts — meaning if legal sites want to appear there, they will need to pay Google for the placement.

When "piracy" became hijacked from meaning the naval context, copying was rampant. In the 80's as kids we couldn't afford all the games so we (illegally) shared them. Hell, I got into computers simply because it was a fun challenge to "krack" software. In the 90's In college/university we used BBS's, FSP (how many know about _that_ protocol!!), FTP with hidden directories containing control characters, IRC with XDCC, binary newsgroup with split .RARs., in 2000's we used Torrents and/or P2P such as Emule, etc. It wasn't until years later did we learn that piracy = lack of respect for the author's distribution. As adults we buy things because we want to support the author(s) to produce more. And if it is crap we vote with our wallet -- and tell others to not buy it.

What is kind of ironic and completely counter-intuitive is that those who pirate tend to spend more but that is a discussion for another day. (Part of the problem is that certain "assets" are not even available to be legally purchased, etc.)

IMHO Piracy begins AND ends with education. Futurama's Bender made fun of this "archaic philosophy" that "Sharing is illegal" by joking "You wouldn't steal X, right? Or would I !" meme along with the popular "You wouldn't download car?" Because most people are able to separate the issue from money vs freedom. i.e. Artists want to share their creations. Consumers want to share those same creations -- that is what culture does -- preserves "popular" art in whatever medium. Unfortunately the context behind those same reason's don't always sync up. You have bands like The Who who don't care about "bootlegging"; other sellout bands like Metallica that only care about the money and could care less if fans help "market" the band.

Kids these day's aren't stupid. They are questing the status quo that: "Why is illegal sharing illegal? Because of arbitrary financial reasons??" id software created the shareware model -- give part of the game away for free, customers can spend money to buy the rest. These days Humble Bundles let people pay what they want. IMHO this is the correct way to do things. Compromise between 2 conflicting ideals. Open Source or Creative Commons is another approach.

Google making it harder to find digital goods is not going to change a dam thing. Google wasn't around when we were kids and piracy was rampant. Removing a search engine will only drive the process back underground when it peaked with The Pirate Bay in the mid 2000's.

Piracy has existed since the beginning of the network. Any technological means to try to remove it is like pissing in the ocean. Yeah good luck with that !

How Lobby Groups Rejected the Canadian Government's Plan To Combat Patent Trolls

By meustrus • Score: 5, Interesting • Thread
The anti-troll measures described in TFA don't sounds to me like they would be particularly effective for most cases. Patent trolls seek out people for whom legal representation is likely to cost as much as a settlement, since those people don't have lawyers on staff and patents are a complicated and specialized field. What the measures would do is provide more opportunities for a lawyer to contest the patent letter. Since the typical targets tend to settle solely to avoid having to pay a lawyer, this will not help. What needs to happen instead is a mandatory notification in the demand letter of certain pieces of evidence which will automatically avoid patent fees if produced. I'm talking known prior art or existing license agreements, as well as other categories of potentially more complicated evidence to be created. Patent trolls thrive on the over-complication in the law, so the solution to them is to create short circuits to their lawsuits that protect 80% of the innocent without retaining a lawyer.

The problem is, what is prior art? It's highly subjective and as such, the law is complicated.

There is no reforming the current system. We need an entirely new system. As is, an inventor has basically no change to win. If he invents something, lawyers find a way to subtly change it to produce it without permission. Likewise, if they have something patented they again get lawyers to find a way to change it and extend that patent into perpetuity.

Patents should be rare. Almost everything should be covered by short term copyright and trade secrets. Patents should only cover truly new and innovative tech. Smartphones are battery powered computers... there shouldn't be anything in them that's patentable. A new form of Fusion reactor? Ok... that's patent. I'd even propose that someone applying for a patent should have to get a court to approve the patent before it being granted.

Any change will have good and bad consequences, and Canada doesn't need much good consequences.

Universities were given as an example of institutions which do real, valuable research and development, but don't manufacture products. They license their technology, so they are non-practicing entities. How do you legally distinguish a research institution and a company who licenses the results of that work vs a troll?

I happen to know that the vast majority of trolling is done by four companies. Hundreds of thousands of people have patents. The challenge is to target those four needles in a very large haystack.

People don't give Launchpad enough credit: for the first time, we have an integrated build/test/deploy process for the whole operating system. It takes the solid Debian root and adds a layer of modern quality assurance that we've never seen before. There's still a ways to go, and I'm sure people will complain about one or other package being broken, but the fact is that Ubuntu raised the bar of what we've come to expect.

Slashdotters and others also love to complain about one particular package or another. Obviously, the desktop environment (or just the shell) is the first thing that most people see. But it's also a small project in the larger scope of Ubuntu. Don't like Unity or GNOME 3 or KDE or Xfce or LXDE or Enlightenment? You have lots of options. Don't like systemd? Well, Ubuntu devoted a lot of time and effort to Upstart, but made the mature decision to abide by Debian's decision to go with systemd (for now). Don't like either? Yeah, well, life these days must be truly hell for poor little you.

And now, Ubuntu may do for mobile what it did for the desktop. In 10 years, I hope we can celebrate the existence of truly free devices, onto which we can install any package we want -- including alternative UIs for those who will undoubtedly not like Unity.

Heck, you could even make it an e-ink background to a nice analog watch for that matter (although that'd probably up the total price). This sort of thing wouldn't need the processing power (i.e. more battery drain) as the current giant glossy types either. Perhaps I'm being naive, but I don't get the high-end luxury approach.

I can't speak for any of IBM's other decisions, but in this case I have to strongly disagree with you. The IBM semiconductor business has been losing money hand over fist recently. They can't compete with Samsung or TSMC on price and volume, and there's not enough interest in specialty chips or POWER to make up the slack. It costs at minimum $5 billion to build a new fab, and IBM would have to build at least one, maybe two new fabs, not to mention updating their existing fabs, in order to be competitive with the big guys.

So, IBM could spend $5 billion - $10 billion just to catch up to their competitors, and still be at a very serious risk of the division being unprofitable, or they could spend $1.3 billion knowing for certain that the bleeding will stop. I only wonder what took them so long.

Also, for what it's worth, IBM is allegedly doing this deal in part so that it can focus more money into design research. They've announced a $3 billion investment into their semiconductor research division, which they aren't getting rid of. The implication is that the manufacturing division was crowding out any other R&D spending, and that IBM can now focus on high margin ARM-style licensing instead of getting dragged further into a war with TSMC et al. that they would inevitably lose.

The Largest Ship In the World Is Being Built In Korea

Posted by timothy in Technology • View writes Alastair Philip Wiper writes that at 194 feet wide and 1,312 feet long, the Matz Maersk Triple E is the largest ship ever built, capable of carrying 18,000 20-foot containers. Its propellers weigh 70 tons apiece and it is too big for the Panama Canal, though it can shimmy through the Suez. A U-shaped hull design allows more room below deck, providing capacity for 18,000 shipping containers arranged in 23 rows – enough space to transport 864 million bananas. The Triple-E is constructed from 425 pre-fabricated segments, making up 21 giant "megablock" cross sections. Most of the 955,250 liters of paint used on each ship is in the form of an anti- corrosive epoxy, pre-applied to each block. Finally, a polyurethane topcoat of the proprietary Maersk brand color "Hardtop AS-Blue 504" is sprayed on.

Twenty Triple-E class container ships have been commissioned by Danish shipping company Maersk Lines for delivery by 2015. The ships are being built at the Daewoo Shipbuilding and Marine Engineering factory in the South Korean port of Opko. The shipyard, about an hour from Busan in the south of the country, employs about 46,000 people, and "could reasonably be described as the worlds biggest Legoland," writes Wiper. "Smiling workers cycle around the huge shipyard as massive, abstractly over proportioned chunks of ships are craned around and set into place." The Triple E is just one small part of the output of the shipyard, as around 100 other vessels including oil rigs are in various stages of completion at the any time." The vessels will serve ports along the northern-Europe-to-Asia route, many of which have had to expand to cope with the ships' size. "You don't feel like you're inside a boat, it's more like a cathedral," Wiper says. "Imagine this space being full of consumer goods, and think about how many there are on just one ship. Then think about how many are sailing round the world every day. It's like trying to think about infinity."

No, when you are working on such a massive scale they really aren't simpler, the engineering and sheer weights alone are astronomical.

Not really, the numbers are larger but the math is very well understood. This is a very mature industry, perhaps the oldest manufacturing industry in the world. People have been building boats for thousands of years. Ship's aren't redesigned every time one is built either. The bulk of a ship is the exact same "U" profile. Design it once, copy it all down the length of the ship. The bow and the stern are the only complex parts, but contribute little to strength. The bow and stern are generally proven designs which are taken "off the shelf" and adapted to the application with only slight changes. Chopping off the back end of a ship (accommodation, engineering, and propulsion area), refurbishing it, and welding it to a brand new ship hull is not uncommon. Unlike with pleasure craft and cars, "style" has approximately 0 design influence in large ships. Everyone is honing in on the most hydrodynamic designs and you can't copyright the math which describes the curves on a ship.

I'm onboard the Tolteca right now, built in 1954/1955. When we were in drydock, the only difference between this ship and ships built much more recently is the distinct lack of a bulbous bow, and the use of diesel propulsion engines instead of a steam turbine.

When I am home or at work, I would be within range of regular WiFi and not need to eat into the data plan or battery life of the hotspot.

Has anyone done something similar? Did the setup work well? Which devices and VoIP services did you end up using? How about software for automatic WiFi handoffs between the hotspot and regular home/work networks?

Re:Battery life

By Mr D from 63 • Score: 4, Interesting • Thread
Good points on battery life. Having the hotspot and the device constantly connected to each other, and monitoring the internet for incoming calls probably will run the batteries down quickly on both devices. Mobile hotspots (I've used a Huawei 3G with great results) will often 'sleep' when not used for a certain period as well, so that should be considered.

As for VOIP service, Vonage ($$) has a nice feature that allows you to share your number between your home phone and mobile devices, and voicemail email alerts, which might be handy in such a setup.

You can stop auto updates on Android devices for the most part, but switching back and forth to auto/manual or manually implementing updates is a bit inconvenient.

In all seriousness: if you don't have an unlimited data plan, you're probably going to blow your data allowance, unless by some miracle you've found a provider that values 1 GB of LTE at an order of magnitude (or more) less than $10 per GB.

If you had an unlimited data plan, you would ideally be able to use the Hotspot feature that's built into nearly every smartphone these days, and forego the hotspot. On Verizon it's an extra $30/mo for hotspot tethering on a stock firmware for phones that aren't rooted, but totally worth it for the benefit you get. This is my primary (only) Internet connection. You could make yours the same if you had unlimited data. It's not new or far-fetched at all.

In fact, if the carriers *did* reduce the amortized cost of 1 GB of data transfer on LTE by a factor of 10 or more, I'd be willing to bet that we would see many millions of people signing up for *limited* data plans on the order of 100 - 150 GB and tethering through their phones or using a hotspot as their primary internet connection. Right now it's simply too much money to get "limited" data plans -- on Verizon XLTE with the MORE plan, you can get like 100 GB for $700/month. It's still way too much money for too little data. Until and unless the prices become somewhat reasonable, so it "only" costs you $2 to watch that Netflix video instead of $20, we will mostly see unlimited data plans as the only users of LTE as their primary connection.

I've had a Verizon 4G LTE hotspot as my sole home internet for the last year. It is the only type of service available where I currently live.

It is expensive and unreliable.

I live in a rural area. I am using an external LTE antenna on the device. I can see that the LTE signal is moderate to good where I am; the problems I am having do not seem to be LTE signal related.

The device itself is about as reliable as other consumer level networking gear -- meaning you need to power cycle it now and then to make it start working again. It has a remote web admin interface, with no way to remotely reboot it. You have to physically touch the thing to power cycle it.

I don't know what's available where you are, but here, Verizon charges me for every byte that goes through that LTE connection, in both directions. I think they're overcharging me, but I have no realistic power to do anything about that, because they are Verizon and I am not. Overages are excessively expensive. My bill for last month was $250. We watch no streaming videos at my house -- not even youtube.

The device stops responding to pings from certain nodes on my internal network, causing all kinds of networking fun. DNS queries randomly fail during logical browsing sessions. I've investigated all of this thoroughly with tcpdump and other tools. This happens on clients of multiple types - OSX, WinRT, Windows, OpenBSD.

So near as I can tell, the box itself is just shit. There have been 2 or 3 firmware updates for it in the year that I've depended on it for my internet. None of them have improved the symptoms I describe.

It's a Pantech MHS291LVW

The entire time I've had it, I've been researching how to replace it with something that isn't Verizon. I'm nearly done with that plan; I'll be backhauling a nearby DSL service back to my site using a 3.5 mile p2p wireless link. I'm paying to upgrade the site infrastructure and wiring at both ends of the link. I am spending thousands of dollars to do this.

My neighbors also have Verizon LTE service. They have the VZN Home Broadband service, where Verizon will mount an antenna at your site and do the install themselves, and the CPE has 4 switched Ethernet ports in addition to WiFi. They haven't complained about the reliability as much, but the price is still too high.

You can only get that hardware from Verizon in my area if you agree to a 3 year contract. I didn't and won't ever agree to any contract with any US mobile operator, so, I couldn't get the VZN home broadband hardware, which may be more reliable than the Hotspot hardware.

They are not power users; they are a young family with ipads for their kids. They recently shared with me that they just had an $800 monthly bill.

I just moved into a new house and haven't yet started Internet service because I have lots of construction going on and am not sure where the cable modem will eventually go (part of the construction is networking the house, and I haven't decided where the network cabinet will go). So in the meantime I'm using the hotspot feature on my Nexus 5 for LTE internet. I get about 5-10 Mbps down, 3-5 Mbps up at this location (500 feet further uphill at the sandwich shop it's 30/9 Mbps, sigh).

My service is with Sprint which typically has spotty LTE service, but fortunately my new home is well covered. Sprint also teamed up with Google so my Sprint number is also my Google Voice number. This means I can make Google Voice calls over LTE via the Hangouts app (Google moved Voice to Hangouts a couple months ago). The app still needs a lot of work (e.g. doesn't integrate with the contacts directory yet) but call quality has been stellar - nearly indistinguishable from when I'm on wifi. I'm actually surprised how well it works considering it's going over a cellular data connection. I mention all this because Sprint is the network most MVNOs use by a huge margin. Since their LTE network is certainly capable of VoIP, any problems you encounter with it are likely to be due to the MVNO blocking VoIP.

Latency has been pretty good too. reports my ping times between 40-45 ms. I occasionally play GW2 over this connection, and generally I haven't noticed any more lag than on a wired connection. Occasionally there's a hiccup like you'll sometimes get over wifi, but its infrequent enough that it hasn't degraded the gaming experience. Overall it's been pretty indistinguishable from FIOS (what I had before the move), and better than the cable internet (I had Time Warner before FIOS, with 150-250 ms ping times).

I'm on an unlimited data plan, so conceivably I could go on doing this forever. The main issue I'm running into (one you shouldn't encounter with a dedicated hotspot) is that my LTE disconnects when there's an incoming call. There's some obscure reason I don't recall at the moment for Sprint and Verizon's phones not being able to do voice calls and LTE simultaneously, even though they could do it in theory. Voice calls go over the CDMA radio while LTE goes over the LTE radio. Unfortunately since my phone is designed to be, well, a phone, I haven't figured out a way to disable CDMA so I can receive the incoming calls over Google Voice. The regular phone dialier and Hangouts both ring when I get an incoming call, but the regular phone dialer locks out the phone preventing me from switching to answer the call via Hangouts (I'm not even sure that would work since it seems to disconnect LTE the moment the phone rings).

If you plan to do this with a hotspot, make sure you can cancel the contract if there's poor service at your house. A tenant at the building I manage opted for LTE Internet (because Verizon DSL there sucks). The building is within their LTE coverage area, and I get a good LTE signal from the roof. But at ground level his hotspot defaults back to 3G and he gets terrible Internet speeds. Unfortunately he got excited and ordered this a month before he moved in, so was outside the cancellation period by the time he moved in and discovered this problem. But I would check first to see if you can use your phone as a hotspot and just beef up the data on your plan.

You're correct. The wavelength of Ka-band frequencies (26-40 GHz) happens to line up nicely with the size of a raindrop in flight. That leads to more atmospheric signal attenuation, but isn't necessarily a deal-breaker; it just means you need a bigger dish to receive it and a more powerful transmitter for the return channel. (The new generation of high-speed satellite Internet services all use Ka band, despite the "rain fade" issues, because the higher frequency enables higher data rates.) In the past, the satellite industry tended to rely on lower frequency bands (such as Ku and C) to save costs on dish/transmitter size because of this concern.

For a cellular service where you're looking laterally at a tower instead of straight up into the sky, the weather issue should be less of a big deal. However, you should note that any frequency that high up will have a very very hard time penetrating indoors through anything thicker than a single-pane window. So expect that this will be used for fixed home Internet applications where a receiver can be permanently mounted outdoors or near a window, rather than traditional cellphone usage that can happen anywhere you go indoors or outdoors.

Sucrose has to be cleaved first into glucose and only starts triggering insulin production after cleavage by other enzymes. This means, qat the very least, that Sucrose gets farther into the intestine before triggering insulin production, and that the rate of production is limited by the rate at which the sucrose is split and not the much faster rate at which glucose enters the bloodstream. I really don't see how you can call those two processes identical.

For example Ketogenic diets have been studied for almost a 100 years by modern medicine, and is used very effectively to control epilepsy. A general public version is known as the Atkins Diet.

There are even some studies that suggest that such diets can protect against Alzheimers:

The ketogenic diet is a high-fat content diet in which carbohydrates are nearly eliminated so that the body has minimal dietary sources of glucose. Fatty acids are thus an obligatory source of cellular energy production by peripheral tissues and also the brain.

In the absence of glucose, the preferred source of energy (particularly of the brain), the ketone bodies are used as fuel in extrahepatic tissues.

there is evidence from uncontrolled clinical trials and studies in animal models that the ketogenic diet can provide symptomatic and disease-modifying activity in a broad range of neurodegenerative disorders including Alzheimer’s disease and Parkinson’s disease, and may also be protective in traumatic brain injury and stroke

I don't have any specific citations but some believe that Alzheimers is like a form of brains diabetes, where the brain cells are no longer able to absorb sugars, which might be caused by modern high sugar diets. Switching to a Ketogenic diet, bypass the brain inability to feed on sugars and is fed ketone bodies instead, potentially reversing the symptoms.
