Unfortunately MS-Access is (ab)used in so many other way. Data entry forms, reports, labels, etc. It is not about the database only stuff. Not every company has time to update all their legacy systems. Trends change, things come and go. If you were starting fresh today, you would make very different choices than 15 years ago.
Thank you for a reasonable sentiment. slashdot is driving me crazy.
The real world is messy. You can't always update everything. You understand this, but other do not.
I have to maintain a Frankenstein PC that interfaces to a multi-million dollar piece of manufacturing equipment. So backups of the hard drives, spare motherboards, CPUs, memory, IDE Hard drives, and other things. This computer is 8 years old, with an expected life of another 7. Yuck! Thankfully its network connection goes to 1 thing and 1 thing only! The PLC. Am I worried about a virus? No. My concern is hardware failing. If someone plugged a malicious USB drive in, then the machine will just be restored to a known good point.
You're getting old. There is so many things in life that are more important. Spend time with your kids and family. For tasks that will run for a while, go do something else while it runs. I'm guessing by your UID, that you have seen IT cycle once or twice by now.
I've done this with m0n0wall. http://m0n0.ch/wall/ A computer with 2 network card. One network card plugs into your network. The other network card goes to your guest wireless AP. In order to block access from the guest wifi to your internal network, you can put in a Firewall ACL to block access to your internal network. For example, if your internal network is 10.10.1.0/24: Setup the second interface as 192.168.1.0/24 (or take your pick). On that interface set a block Firewall rule for all traffic with a destination of 10.10.1.0/24. The guest Wireless can still get to the internet, but not to anything on your internal network.
Because smart meters are probably using some sort of zigbee or other 802.15.4. It makes sense for smart meters to run in a mesh. That way they do not have to have direct connection to the data collection unit. They can use the mesh network to hop over multiple nodes to get the data to where it needs to go.
I will second both points of this. Using buildroot for multiple types of boards/chips. buildroot helps in creating a reproducible toolchain, kernel, apps, and filesystem images. You can add your own application (The main thing to run) as a custom package. http://buildroot.uclibc.org/
The Atmel at91sam9 series runs fine. Both in graphical and non-graphical environment. I use this for quick proto type testing/dev: http://www.mini-box.com/pico-SAM9G45-X (however, I add NAND Flash for os/apps)
As others have stated, Angstrom is also good for building the OS/applications. The build system takes a little bit more care to setup than buildroot. http://www.angstrom-distribution.org/
How are we supposed to kill it if it's self-healing? Now it will never die!
Make sure the halon system is not computer controlled. Kill internet connections to all sites at the same time, so they cant send out an SOS Then kill the power
In Theory... So if 1 million people manually send an email no more than 100Kbytes in size, that is 100 MBytes. Seriously? A single email account at a company has less than a 100 MB mailbox (or even free space)?
This has created a unstoppable force with one exception. the test unit of 12 team members were highly effective until their DSL connection at the pentagon was DDOS attacked. The Government is asking for Congressional funding to get more DSL lines installed but the current Tea-Party members are claiming that it is an un-needed expense.
Of course DSL lines are an un-needed expense. Each solder needs their own array of fiber optic links to each country.
I forgot to mention, if you are in the U.S.A, then is is also quicker chipping wise to go with dorkbotpdx mentioned above. Simply for shipping times alone. Seeedstudio's fusion service only e-tests 50% of the boards by default. Even then, I have still had boars that pass e-test, but where the copper meets the pad, it is too thin. This will break the connection. Yes, plated through holes are a little bit harder to re-wrok, but with a little flux and the heat turned down, it is do-able. I have ordered from Seeedstudio's fusion service over 10 times. Although they are cheaper, I ended up spending more time repairing bad boards. I have switch to dorkbotpdx and have not looked back.
There is also batchpcb, but their prices are higher. Also last time I check batchpcb only had green silkscreen and a minimum of 8 mil traces.
I have a few of DPs products. The webplatform is cheaper and more useful to me than an arduino/ethernet shield or even the new EthernetPro http://www.sparkfun.com/products/10536
Seeedstudio's fusion service is good price wise, but I will not have PCBs made through them again. Too many bad traces. Pads lift if you try to re-work them.
Arduino is a great starting point for micro controllers. You can put in raw AVR C++ code into the ide if you want. Personally, Arduino helped me get going quickly. Then if you outgrow it, you can use the same hardware and program without the IDE and all the libraries if you want. From there, it is easy to move to other ATMega/ATTiny chips if you need to.
Arduino is more than make an LED blink. There are libraries for LCDs, Ethernet, read/write SD Cards, and examples for many sensors. (and much much more)
I am not a programmer, but with the available libraries, I was able to accomplish many projects quickly. In less than a year of using arduino in spare time, I learned enough to move on to other AVR micros. GCC supports AVR micros. The TI Launchpad is highly restricted to windows.
No comment on PIC. Have not had time to try programming with PIC.
Agreed. I've been using linux since Slackware 96. xorg.conf was a bear to get working. As you get older and get a life, it's nice to have ubuntu. I'm glad for having a slackware background for many years. It taught me all about the internals of linux. It taught me to appreciate a package manager that handles dependencies. (I enjoyed compiling software by hand. I didn't mind having to grab multiple libraries to install software. I remember the summer of 1998 compiling KDE 1.0 took all day with a ton of dependencies.)
It is nice having Ubuntu on a laptop, and all my devices are recognized. That allow me to focus on getting work done. It gives me more time with my family.
What about the very last switch before the thin clients? Sure, it can have a connection to two different switches. That doesn't help if that switch dies or a misconfiguration. That could be 20 or more thin clients without a connection. The thin clients don't have redundant network connections. Most of the ones I've seen only have one ethernet port.
being able to stream all those movies and music thats stored on your computer. (you know your house is already networked) you dont even have to have a computer in the living room anymore. plus you can run linux and turn it into a X console or anything else you can dream up.
I have a tiny tiny screen built into a osborne computer that runs CP/M. I dont use it too often anymore, but it still works. now im sure the rest of you have real monitors.

With either m0n0wall or pfsense, you can setup captive portal. This will block outgoing connections until the user registers or logs in.

Slightly more expensive, http://dorkbotpdx.org/wiki/pcb_order , but I have never had a bad board and the quality is much much better.
