it makes good sense to charge specific tolls on such roads. the problem is that government rarely agrees to cut one tax in exchange for another. The motorists that pay that specific toll are also still going to be paying the same taxes for other roads via vehicle registration and state and city fuel taxes. I doubt that any state that puts toll into place will reduct those taxes as a result of not having to maintain the tollway, rather they will just absorb the additional revenue.
on the same note, i see the value of conjenstion fees is cities like London. If the state government must only cover the costs of roads in residential areas and rural roads and let congestion fees and tollways pay for themselves then the people outside the city can pay less for roads, which is ideal as they typically make significantly less salary and put less burden on the roads (typically).
I would also expect to see polorized license plate covers that block light from reflecting at angles so the cameras have trouble pulling the plate number. I know that there was some of this going on in the UK but I dont know if the city found a way around it. I was speaking to a guy there and he said that the fines for having the cover were only about a months worth of conjestion fees and you would likely only get busted once a year making it 1/12 as expensive.
I think that this is more likely. some sort of co-processor to sit on graphics board. They may find ways around a number of patent issues if they are just building the x86 logic and using the graphics core for the number crunching. seems to me that this is likely a way to get into the mobile market with a GPU that powers the whole thing and an x86 add-on that makes the GPU look like a standard desktop CPU.
kinda of transmetta think except with GPU hardware and an FPGA or something for the x86 work instead of pure software
i argue that the location of the school should not effect the curriculum or the specific tools of the curriculum. Funds should instead go to making the school safer than the environment it is in, programs encouraging kids to be at the school. This may include better computer labs and more programs but the classroom itself should be similar across the school system. I guess i would also contridict myself a little bit in saying that the teachers and the headmaster/principal should have some active role in this and that all school do not need to be identical, only equal.
This should be decided school by school, because each school may have a different demographic, and that could quite possibly change the type and quantity of technology used.
wow, demographics in school. is this seriously something you consider to be acceptable? demographics in school creates a division in the education level. demographics are something that is learned about in school but should not be applied to school for the purpose of learning. maybe for security, but not for learning.
1) Teacher workstation in each room, with projector and an "Elmo."
2) Computer labs, with thin or fat clients, depending on your needs.
3) Laptop carts, so individual classes can use a set of laptops if needed.
I find that having a desktop scanner/elmo scanner and a workstation at the teacher's desk with a projector is sufficient. A lot of classroom teaching requires or benefits little from the student having access to a laptop. but giving the teacher the ability to throw some document up on the projector is very very handy. even better is if the teacher has a touchscreen computer so that they can draw directly on the document and then print the thing when done. This is a modest investment for each classroom and has tangible benefits.
I am a big fan of the LTSP. I can get referb HP or Dell workstations with 2Ghz CPUs and 1GB RAM for under $100 plus a $100 monitor. These make great Thin clients and simplify administration and security. You can put together a computer lab with 40 workstations for $8,000-$10,000 with some volunteer work from the local LUG. Additionally you can run many windows products on WINE or via a Terminal Server and the RDP client or better yet, use open sources apps.
You wrote them on your paper. You own the notes and this is theft. Did you sign any contract at the beginning of the class that would require you to release your notes?
Though *MOST* of my tasks are not I/O bound, the ones that I wait on the most ARE I/O bound.
Seems that the controller here needs a clock speed boost. there is no reason this thing shouldnt be able to crack 550MB/s over 2 SATA300 interface other than a slow controller.
This review should have also included a software RAMDISK running off system memory. It would be interesting to see what the chipset's capabilities are vs this thing.
true enough. but I do about 99% of my typing in english. Qwerty is a romance language specific layout geared towards english. It is adapted to other languages pretty well but a dvorak for danish could also be made where qwerty for danish is a bit lacking.
Remember that qwerty was also designed to make it easy to type english words. Other romance languages have different letter combinations that are not ideal for qwerty.
I learned to type on a dvorak layout keyboard years ago and do find that there is a lot less hand fatigue and improved typing speed for me.
Just like many things, I am sure that dvorak is better for some than qwerty and equal or worse for others. I have average guy hands and dvorak is nice for me.
That said, I type exclusively on qwerty now because I dont want to veer off the standard layout.
All you people up there in City Hall, You're fuckin' it up for the people that's in the streets. This is a song for the people in the streets, Not the people City Hall. All you motherfuckers in the streets it's time to rise up, up up up Come along children and fuckin' rise!
Lots of times when me and KG are watchin' All the fuckin' shit that goes down at City Hall, We get the feeling we should fuck shit up, Yeah we should fuckin' start a riot. A Riot!
We have 'em screaming in the streets, we have 'em tippin' over shit and breakin' fuckin' windows of small businesses, and settin' fuckin' fires! and settin' fuckin' fires! and settin' fuckin' fires!
I also spent some time in Europe and came to love the public transit systems they have built.
Our distances are greater between major cities but there are already rail lines running between all major us cities, they are just not used for passenger rail.
Some infrastructure improvements would open these lines up for public transport.
Some people seem to think that Europe's population density enables their public transit but never take a second to look at population density in urban areas. We have similar population density in urban areas, it is the rural areas that are sparsly populated. We could have similar public transport here in urban areas but we dont. Some cities have ok setups but the vast majority do not.
We also tend to try to sprawl our cities out over large plots of land and reject multilevel cities unlike europe. Most US cities are average 1-2 stories for residences while European cities tend to average 3 or so.
I'm not saying we should become clones of europe, but we should learn by their good and bad examples.
man has been living with artificial light on the yellow side for the better part of 20,000 years. 6K artificial light 'feels' unnatural while more yellow light feels better.
except that his routers are on the internet. Because of that, he may be able to setup ipsec tunnels between remote branches allowing bittorrent to be usable.
His clients would all still be locked away inside his private network, but that network would have a mesh layout where each site can see some or all of the other sites.
I think you need to complicate this logic a bit by taking into account added electricity required to power the extra servers, run the servers at a higher load, or run the clients at a higher load as well as the air conditioning cost increase as well.
also, time is money. If a program takes more time, there is more time for users to be idle which will also have a cost.
best practice? program as efficiently as possible. Programming expenses are only spent once which the power bill lasts forever.
I personally get nauseous from any perceivable flicker and am very sensitive too it. I only last about 5 minutes in regular florescent lighting.
I know that I am ultra sensitive but there are many people with various degrees of sensitivity to such flicker.
I also dislike pure white light. It is uncomfortable to look at anything in pure white light.
LED is a great technology but despirately needs to develop natural light replacements and/or incandescent replacements. A couple million years of evolution has tuned my preference of lighting.
get a small pc case such as one of the many small cube cases that come as a barebones. Put a dual core chip and 2GB ram. The you can install something like openfiler which will give you a nice web interface and the ability to do nfs,cifs,ftp,and iscsi. Alternatively, install solaris or opensolaris and use ZFS and have the ability to compress the files at the filesystem level and also do a raidz with 3 drives for reliability and speed.
either way you can bond two ethernet interfaces together for 2Gbit which should get you 80-100MB/s realworld bandwidth.
agreed. Have you been watching the economy? well-funded shouldnt imply retarded.
If you maintain a culture of appropriate thriftiness at every level of your organizations, you will likely never get to the point of having 1 executive riding a private jet that can move 20 people for a dinner meeting.
That being said, bandwidth can be pretty cheap and at most places around the country you can get 20Mb of fiber for $500-$700/m.
Remeber the key word in the phrase, "appropriate" thriftiness.
I also assumed that this was hub and spoke and that the "to each other" statement was just routing. Depending on the number of remote sites, and that he did not mention a specific hardware supplier, I would assume that a meshed ipsec VPN setup would be a task to maintain as it would likely be all manual.
I am all for open source systems but find that Cisco 8xx series routers are well priced(under $500) and easily managed for easy mesh vpn setups for up to 20 links. I run this setup with a ASA5510 at the center and each site connected to the ASA and 4 other sites for remote administration office and any other connections are just routed. Basically a hybrid hub&spoke + appropriate meshing.
consider scripting the process of creating a torrent file of the data that needs replication. At each remote site, run some linux or bsd system and setup ssh keys so the central server can run a script on each remote machine.
setup a local bittorrent tracker.
On the main server, script building the torrent file and run an upload script against a list of remote sites that would download the torrent file via scp and run it until it has seeded out a given amount OR has run for x days.
The only issue here that I see is that you said that you are using ipsec over DSL which implies that all of your bandwidth goes through the central site anyway. You would need to build ipsec tunnels between sites and make sure that you have routes in place to use the secondary tunnels for appropriate IP addresses.
With zfs and dtrace, you can build a nice small business storage box.
Keys are ECC ram, quality components from trusted vendors, and a good spindle count to catch bad drives.
Many SATA drives in a 16 drive array with a few hot spares and the ability to swap in drives as need running on Solaris with ZFS is a good setup. You dont need to spend $12,000 on this, you can spend half or 1/3 that in a small business environment.
Operating System is more than the kernel. All varients of ubuntu essentially use the same kernel, though some are slightly tuned. The 'OS' part is the combination of a kernel and supporting programs to create a completed system.
A server OS is a kernel plus programs that server content of some form or support the programs that serve content.
A desktop OS is a kernel plus programs that create the desktop analogy that allows users to interact with client programs.
Windows server 2008 and Windows Vista share a common kernel and a few (ok a 'few' might be the wrong term in microsoft land) programs but differ in the types of programs that come installed and therefor differ in the 'system' that they provide.
RHEL5 and Fendora 10 share the same kernel (or very similar) and some programs but Fendora comes loaded with compiz and a number of desktop programs while RHEL5 comes with many server programs and some graphical interfaces to configure them. RHEL5 is a server system 'server OS' and fedora is a 'desktop OS' by virtue of the installed packages and the configuration of the system.
They can be made into some sort of hybrid where a desktop OS has server software installed but the core set of applications that made it a desktop in the first place are still there, with the function of being a desktop and without the function of being a highly secure, server system. If you pare down the Desktop to make it server-level secure(only services necessary to provide the service and the interface to configure the service), then you have modified the system to the point that it is a server OS.
I am a forward thinking, progressive sysadmin. I admin a dozen DEC Alpha ES45 systems on tru64 5.1b, A web cluster on ubuntu 7.04 being updated to 8.04 with 10 nodes, 120 remote sites over vpn tunnels on cisco hardware, a growning SAN with over 30TB, and a 8 node, 32cpu xenserver cluster with a varienty of single function vms running linux, windows, and freebsd.
I have some experience in servers and desktops and related security. The lines do not cross in a secure environment. Ask any admin that follows best practices and tell them to stop smoking that bullshit and you will promply be geekslapped.
despite the differences between linux and the unixs the model is similar enough to windows to be true. The point may be easier to make in the windows world considering the common base of vista and server 2008 but they can easily be seen as 2 distinct OS. linux and unix do have a much finer line.
Sterling engines gain efficiency when the delta temperature increases. They are also better at producing a steady "static" power source rather than "dynamic" power source like an auto engine. They should be a efficient way to boost power by converting excess heat for any mechanical system into electrical power.
If the fluid medium is chosen correctly, then the difference between outside air and the engine in a car could be an extra boost to a hybrid system with a small expense in weight because many plastics can handle these temperature ranges and the fluid medium is a near-zero weight gas.
So in conclusion, a sterling engine can suplement an existing cars power but certainly cannot be the primary power source short of a nuclear heat source.
Many of these services only listen on 'trusted' interfaces or the loopback interface. Also, as long as each port the server listens on is known and secured this makes sense.
The point is that if you netstat and cant explain each port that is open and be confident that it is secure then this is acceptable. In a desktop variant, the user did not select the open ports and often cannot explain why they are open. Many programs on the desktop that are insecure listen on public ip addresses.
