Someone beat the guy over the head with a clue-stick and stop the PR spin-wheel from being so absolute obvious. Just about EVERY enterprise level backup tape system supports built-in hardware encryption! You don't even need your software level stack to do it. The hardware itself encrypts the tape as it writes the data based on the firmware settings you configure on the device. It then automatically de-crypts it when it reads that tape later as it uses the same access keys/settings you gave it originally. So I call complete BS on "it's very hard to encrypt a backup tape" answer...
We have all know it was security theater from day one. It was much more about the perception of security than actual security. I am sorry to say it, but what we needed to do is what the majority of the middle east has done in terms of airport and public space security. It has been fairly well proven effective and not unduly intrusive or burdensome. But profiling is just seen as too much of a PR and PC disaster to do it in the USA. That is part of the approaches used in those countries. You give scrutiny to the people who are most likely to be the threat, not the 4 year old child who is screamming at the top of their lungs "BAD TOUCH!!!!!" "BAD TOUCH, DADDY!!!!!!"
I can not stress this enough. As good as 10gb ethernet is, the latency is still horrible compared to infiniband.
As for distributions, really, that depends on what you are doing and how your current applications are built/designed. Rocks cluster is fairly nice. Unfortunately we have not been able to deploy that due to our FOSS policies, which have really been hurting this project. So we have a mixed Red Hat and Solaris cluster using Grid Engine.
Just wondering if his plan fixes and replaces the 2 different power grids Japan has. They have a 50Hz grid and a 60Hz grid, with several power converts between the grids, but they can only handle about 1GW of power transferred between the two grids (which is why when the earthquake/tsunami caused many of the nuclear plants to shutdown, even though they had the capacity on the other grid to handle the losses, they didn't have the ability to transfer the power to the other grid, and had to have rolling blackouts in Tokyo since it was located in the same grid affected by the shutdowns).
No, he owned the North America distribution rights, not the copyrights I believe. Apple Corps Ltd., (no not Apple Computers) owns or owned the copyrights.
As the subject says, small, quiet, and performance, choose 2. You can easily make a passive cooled (quiet), high performance system to do emulation, it won't be small. You can build a small, high performance system, it won't be quiet. You can build a small and quiet system, it won't have the performance needed. Pick your poison.
Personally I am of the quiet and high performance kind of person. Go get a nice Antec Fusion Remote MAX case, slap together a nice Intel i5 system, put in a big massive Noctua NH-D14 heatsink on it, along with a passive AMD/ATI HD5750, and be done with it. You can try and get by with one of the 35W TDP Intel's in a mATX case, but it might not be enough for you to do some of the trickier emulation. Heck, some SNES stuff still can't be done right on the fastest CPU's under emulation, let alone anything past the 16bit era....
Actually, look at that patent and the drawing. Remind anyone of the Power Glove? Sensor on the top of the TV, and one on the side of the TV.... Detects as the device moves up/down/left/right.... Sure the Power Glove wasn't completely wireless, but the concept on how it's movements were tracked certainly were.
Hey Microsoft welcome back to 1992. You know that time when the OS ran the computer and a desktop environment ran on top of the OS, like DOS and Windows 1.0, and Unix and Motif or CDE or...
There was a reason why Unix and Linux never stopped operating in that mode. Glad MS finally joined the club again.
We irradiate meat after the animal is DEAD! At that point, there is no problem with DAMAGING THE DNA, RNA, and mRNA, because THEY AREN'T BEING USED ANYMORE!
I and many EVE players will agree 100% with what you said. However, the reason there is an in-game to real life money conversion in EVE is because you can buy game time with real money, convert that game time into an in-game item which can then be sold for in-game money to another player, who can then convert that item back to game time on his account (or a few other services such as character transfers/portrait changes, etc). But the overall idea is simply that some people will have real money but not time, and others have time but no real money. This allows both those groups to enjoy EVE as many people will happily buy game time for the current rate of in-game money since they have good in-game income sources and/or play time dedicated to earning it.
There was recently (end of July) a pretty large revolt in the game based on leaked emails and internal communications from the developers/management at CCP (the makers/runners of EVE) about allowing other items to be purchased with "micro-transactions". That was all about what you are talking about. Most a perfectly fine about the current system of simply trading items which can be redeemed for game time. It is when you can start buying ships, equipment, stat boosts, etc., ( and in this case "gold ammo") that everyone has a problem. CCP is in a bad spot financially right now because they have bitten off more than they can chew. They are developing 2 other games at the moment in conjunction with continuing to run EVE, with their only income stream being EVE. And they took out a lot of loans to develop these 2 other games which are due up in September/October, but those games are not out yet, and are not generating income. Thus their only income stream is EVE, so they were trying to find ways to take advantage of the whole free-2-play model that some new games are using by introducing micro-transactions. The problem is the game isn't free-2-play and the player base didn't like the fact that they were seeing a their in-game market possibly get destroyed by having CCP add an additional way to buy items (i.e. direct purchase and not thru the current in-game systems which are controlled by the players themselves, who mine the minerals, refine the minerals, research the blue-prints, manufacturer the components, manufacture the item, haul the items to market hubs, and sell the items on the market, all of which takes time, required significant investment in both skills and assets to perform. And now CCP was just going to update the database and "poof" add magic items into the game). This would destroy the game market as there multiple prices for the same item would not be tolerated, and would get correct via market forces, but the only market force that is able to change is the one run by players, as CCP's prices would be whatever they decide worked best for their quarterly statements, which means that it would drive a lot of players out of the market, people who have invested billions and even trillions of in game money to make the items they are selling and have certain fixed in-game costs in creating the item, while CCP just updates a database.... Thus the revolt.
Look it up. These things will give you a more focused connection, but you will need setup the antenna correctly for the space you are using. I am assuming you have your wireless router/access point hardwired in your kiosk space. You need to setup 1 or 2 directional antenna and point them (preferably from above) at the area that you have your equipment/devices/demo space. The antenna you use will be dependent on the wireless connection frequency you use (802.11 a/b/g/n 2.4GHz, or 802.11n 5GHz). It will also depend on what kind of access point/router you have. Obviously this only works on routers which support different antenna, like the infamous Linksys WRT54GL.
Personally I have a 19dbi panel antenna which I use on emergency, which I carry in my laptop backpack along with the said WRT54GL. I have been able to pickup and connect to networks 2 miles away (with line of sight) in bridged mode to allow my laptop to get on the net in a pinch (this was before phones had data/internet access). Worked out great for a school project once where the class was held at a remote location and we then had to write a team report/paper on about it. The professor gave bonus points to the first team to complete the assignment and sent it to him via email. We were already working on laptops, and I simply broke out the router, aimed the antenna back at our campus, spoofed my laptop's wireless mac address for the router's (since my laptop was on the approved wireless access list), and we sent the report. We also let our professor connect his laptop so he could receive it:D
There has been an extensive road upgrade project in New Jersey to remove all the "roundabouts" (called "circles" here). Why? Because they only work under light traffic volume. Under heavier traffic conditions, you get either long backups leading into the "roundabout" or have lots of vehicle accidents going into/out of the them. I know of 6 that have been completely removed with another 3 that are in the planning stages of being removed. They are all being replaced via traffic lighted intersections (in some cases 3 or 4 due to how many roads connected with the original circle, since many of these have been here since the 20's when cars first started appearing in quantity).
You can't patent numbers or algorithms, which is exactly what software is. Their bids were their tongue-in-cheek way of trying to point that out yet again. Software under no circumstances should be protected under patent law, and instead should fall purely under copyright law. Maybe one day when someone appoints a Judge that has experience there will be someone who "gets" it.
I really don't think so this time. There is a thread on the eve forums where everyone is posting their cancel subscriptions. I cancelled both of my accounts. While they don't actually expire for another few months, unless the major questions are answered, that will be it for me an EVE.
To recap for those that don't know, the major questions are as follows:
1) Will there be microtransactions for in-game items or services which affect actual game play or offer advantages (basically anything but cosmetic changes)?
1a) If so, how are you going to keep the market in check when you have 2 main currency items which will have different trade rates depending on how you purchase (i.e. currently people can buy a (G)ame (T)ime (C)ard (GTC) and convert that into a (P)ilot's (L)icense (Ex)tension (PLEX) which can be traded sold or traded to other characters on the market. This current trade is well established with supply/demand with the going game price of a PLEX fluctuating between 300-400million. Now if you add microtransations, which are based on a new currency based on PLEX (1 PLEX = 2500 AUR), are you going to fluctuate the AUR price of items as the in game market conversion rate on PLEX to ISK and the current market prices (ISK to item) change on a minute-by-minute basis?
Basically what everyone is protesting is the how this will break EVE's market system as you can not have 2 conversion rates for the same item, with CCP setting hard rates on an item via their store, how can in-game players compete with that market when CCP can simply change a number in a database and suddenly have 1 million of the item? The market is the driving force of the game, and by manipulating it like this, they will destroy every segment of the market by either pricing the items out of the range that in-game players can compete with (i.e. you have to pay the miners who mine the ores, the security forces who keep the miners safe, the haulers who move the ore to processing stations, the protection details on the haulers, the people who refine the ore to minerals, the researchers who research the blueprints/purchase blueprints for the items, the manufacturers who provide the manufacturing lines to produce the items, the haulers who move the items from the manufacturers to the trade hubs, the protection details who fly security for the haulers, and finally the traders who put and manage the items on the market.... That is a lot of effort that occurs in the game right now to make anything from ammo, to ships, to space stations. And the prices in the market fluctuate depending on how much effort was needed, how efficiently they could make the item, the raw material costs/value, etc.. Anything that circumvents that process, will cause the market prices to change possibly to the point that in-game players can not compete against the store, which means they need to figure out something else to do to make money in the game, and their possible 2-3 years of investment in skills required to do what they were currently doing was completely wasted and pointless. And in EVE, the skills are the investment. You can't simply remap your existing trained skill points to switch from being a miner to a combat pilot, or a researcher to an explorer, or a hauler to a manufacturer. It takes years in some cases to learn the skills required for a particular job (last check it was 177 days just to fly a titan, but that is without any equipment, approximately 3 years to fly and fit it properly).
Yes as having power generated at the site of usage removes the transmission loss from the equation thus improving overall energy usage efficiency.
No because most all solar power used at residences are silicone panel collectors, which use a lot more raw materials for the energy output they produce compared to concentrating arrays (which use lots of space with mirrors which are much cheaper to produce (both in costs and energy/waste usage) than panels for the same energy output, but require more physical space.
So like everything there are pros and cons. Since most people don't own enough space where motorized mirrors can be placed, you don't see many concentrating solor power installed at residences.
Just wondering what the definition of "mobile device" was, since many cars have been collecting location data now that many have GPS systems in them for a while.
If it works as described with the PCB generating heat to change the substance from a crystal to a liquid, once that heat is removed via loss of power, all would change back to a crystal, and you would lose all your data. This may be fine for RAM, but not for storage.
You then havn't been looking at the more prominent certs then. My Solaris 10 System Administrator certification has a website where I can request that Oracle (the certificating body) send verification of my certifications to someone (for jobs/contracts/interviews etc).
For anyone working at a place like this, they know that the real data is on a separate network which has no physical connection to the internet. The only data that could possibly have been compromised would be unclassified, business trade secrets, and/or proprietary information.
As the one official said (which was almost completely ignored by the article's authors), there should be little risk to actual projects. Really, what they got was access to "TPS reports", and other such documents. Now, there may be an issue with "Export Control" as even if some documents are unclassified, they may not be allowed to be transmitted to certain countries. But all the real information is on that other network which you need physical access to hack, which is one of the easiest things to secure.
As an admin of a cluster that has evolved and changed over the last 7 years, I think I can help a bit. That being said, you truly failed at defining your real needs. I understand liking to stay with what people know, but from an end user point of view with interactions with a cluster, the only interface that they use is the only thing that needs to stay similar, and you can almost certainly use the same interface on any other linux distribution. So that said, what are you currently using to submit, queue, and schedule jobs? There are a few proprietary solutions out there and several open ones. There is Grid Engine (or Sun/Oracle Grid Engine), PBS, Maui, Torque, and several others out there. That should be the only real interface that an end user should have to the cluster.
Now comes the second question I have. Why do they need to be running X? I can understand having the X server installed and all the libraries, but you absolutely should only be running your servers at run level 3 (i.e. command line). You can still run applications if you set your display to a remote X server as the output device, in this case one that you run on windows desktop like Cygwin, or Xming. All you do by running X.org on the cluster nodes is waste about 1 gig of memory and 5-10% CPU resources, which could be utilized by your end users' jobs/applications.
Third, what kind of applications are your end users running? Are they real parallel environment applications using some sort of MPI (LamMIP/OpenMPI), or off the shelf products like Clustered Matlab (which actually uses MPI, but it is built into the product already, you just need to configure it properly)? Or are you really just running lots of batch jobs which may or may not be multithreaded applications, but do not do any intra-node communication?
Fourthly, how are you monitoring your existing cluster? Are you using something like Ganglia?
Finally, what kinds of third party software do you need to be able run/use? Is there anything that is commercial which may have limited support to specific linux distributions?
All of those things are questions that you need to really answer in order to recommend a distro.
All things being equal, personally, I would deploy a cluster using "Rocks Cluster" distro. It is designed from the ground up to be a easy to maintain and deploy cluster distribution. There are plenty of HPC specific packages/application/libraries available to be deployed on the nodes. "Rolls" are available, which basically contain a group of packages/applications/tools which are typically used together, or otherwise easily configure/install software that is required on each system, possibly with some complex interactions (for instance there is a "Ganglia" roll, which easily installs the Ganglia cluster monitoring software and automatically sets it up based on your Rocks installation. There is a "BIO" roll, which contains many open source tools and librarys which are useful in doing biological research clusters, like ClustalW, Glimmer, NCBI BLAST, just to name a few. Then there is the HPC roll, which is just some basic things like MPICH, MPICH2, OpenMPI, iozone, iperf. There is also a roll for PVFS for setting up a quick Parallel Virtual File System cluster).
It is designed from the ground up to be a cluster, not just a bunch of nodes running linux with high speed interconnects. It has management utilities to deploy applications across all nodes at once, quickly install OS on all your cluster nodes via PXE booting the compute nodes. Flash/upgrade the BIOS of computer nodes remotely via PXE boot. Basically it is designed to be managed and maintained as a cluster, not "x" number of individual systems. Seriously consider something like it.
The problem is that in Estonia, you only need a network that can handle 2 million people (which gives room for 30-35% population increase/tourists over total population in the country). Just covering Chicago alone has more than double the population of your entire country....
Like you, I saw the same thing. That said, I also configured my system to respond as though it was a Windows 2000 server, when in reality it was a linux box, so it could try guessing "administrator" all it wants....
That said, I also wrote a script and cron job to parse all the access logs, keep counts of failed login attempts by IP address, subnet, and ISP block, and when they hit certain thresholds, update my firewall rules to reject all connections to that address, subnet, and ISP. I saw a lot of stuff coming out of China and Hong Kong for a long time there (probably other compromised systems), but I am not too worried.

For anyone working at a place like this, they know that the real data is on a separate network which has no physical connection to the internet. The only data that could possibly have been compromised would be unclassified, business trade secrets, and/or proprietary information.
As the one official said (which was almost completely ignored by the article's authors), there should be little risk to actual projects. Really, what they got was access to "TPS reports", and other such documents. Now, there may be an issue with "Export Control" as even if some documents are unclassified, they may not be allowed to be transmitted to certain countries. But all the real information is on that other network which you need physical access to hack, which is one of the easiest things to secure.
As an admin of a cluster that has evolved and changed over the last 7 years, I think I can help a bit. That being said, you truly failed at defining your real needs. I understand liking to stay with what people know, but from an end user point of view with interactions with a cluster, the only interface that they use is the only thing that needs to stay similar, and you can almost certainly use the same interface on any other linux distribution. So that said, what are you currently using to submit, queue, and schedule jobs? There are a few proprietary solutions out there and several open ones. There is Grid Engine (or Sun/Oracle Grid Engine), PBS, Maui, Torque, and several others out there. That should be the only real interface that an end user should have to the cluster.
Now comes the second question I have. Why do they need to be running X? I can understand having the X server installed and all the libraries, but you absolutely should only be running your servers at run level 3 (i.e. command line). You can still run applications if you set your display to a remote X server as the output device, in this case one that you run on windows desktop like Cygwin, or Xming. All you do by running X.org on the cluster nodes is waste about 1 gig of memory and 5-10% CPU resources, which could be utilized by your end users' jobs/applications.
Third, what kind of applications are your end users running? Are they real parallel environment applications using some sort of MPI (LamMIP/OpenMPI), or off the shelf products like Clustered Matlab (which actually uses MPI, but it is built into the product already, you just need to configure it properly)? Or are you really just running lots of batch jobs which may or may not be multithreaded applications, but do not do any intra-node communication?
Fourthly, how are you monitoring your existing cluster? Are you using something like Ganglia?
Finally, what kinds of third party software do you need to be able run/use? Is there anything that is commercial which may have limited support to specific linux distributions?
All of those things are questions that you need to really answer in order to recommend a distro.
All things being equal, personally, I would deploy a cluster using "Rocks Cluster" distro. It is designed from the ground up to be a easy to maintain and deploy cluster distribution. There are plenty of HPC specific packages/application/libraries available to be deployed on the nodes. "Rolls" are available, which basically contain a group of packages/applications/tools which are typically used together, or otherwise easily configure/install software that is required on each system, possibly with some complex interactions (for instance there is a "Ganglia" roll, which easily installs the Ganglia cluster monitoring software and automatically sets it up based on your Rocks installation. There is a "BIO" roll, which contains many open source tools and librarys which are useful in doing biological research clusters, like ClustalW, Glimmer, NCBI BLAST, just to name a few. Then there is the HPC roll, which is just some basic things like MPICH, MPICH2, OpenMPI, iozone, iperf. There is also a roll for PVFS for setting up a quick Parallel Virtual File System cluster).
It is designed from the ground up to be a cluster, not just a bunch of nodes running linux with high speed interconnects. It has management utilities to deploy applications across all nodes at once, quickly install OS on all your cluster nodes via PXE booting the compute nodes. Flash/upgrade the BIOS of computer nodes remotely via PXE boot. Basically it is designed to be managed and maintained as a cluster, not "x" number of individual systems. Seriously consider something like it.

The problem is that in Estonia, you only need a network that can handle 2 million people (which gives room for 30-35% population increase/tourists over total population in the country). Just covering Chicago alone has more than double the population of your entire country....
Like you, I saw the same thing. That said, I also configured my system to respond as though it was a Windows 2000 server, when in reality it was a linux box, so it could try guessing "administrator" all it wants.... That said, I also wrote a script and cron job to parse all the access logs, keep counts of failed login attempts by IP address, subnet, and ISP block, and when they hit certain thresholds, update my firewall rules to reject all connections to that address, subnet, and ISP. I saw a lot of stuff coming out of China and Hong Kong for a long time there (probably other compromised systems), but I am not too worried.
