I second this. We do this for our retail locations. We have two ns-208 models running in Active/Passive mode and install either Netopia 3386 or Netscreen-5gt models in our stores.
The total cost on the concentrator side was 30K but it's redundant and the cost of the remote routers are $250/$400 respectively.
Right now the parallelism is killing us. It does us no good to move to a bigger box because our warehouse loads have to be ordered a certain way. About the only thing more CPUs buys is the one rougue query done by a stupid user who thinks they know SQL.
I'm actually really interested in the stuff Greenplum is doing.
One thing we're really looking at from 8.1 is the bitmapped indices and the table partitioning.
Interestingly enough, you'll have the same results when putting out an ad for a DB2 UDB dba. These people get somewhere and stay there or they're all consultants. We search 6 months for a full-time DB2 DBA and just hired one a month ago.
In our environment, we've basically broken it down to DB2 DBA and SQL DBA (which is the dumbest thing I've heard of).
The DB2 dba handles all the DB2 servers and the SQL dba handles EVERYTHING else (mssql, postgresql and mssql).
Example: Our ETL vendor, Informatica, doesn't support PostgreSQL or MySQL and refuse to even help with the issues. Our BI vendor, Actuate, rebuilt our environment and provided a custom build of the package to make it work with PostgreSQL.
Interestingly enough, Informatica costs a fortune compared to Actuate.
There are also SEVERAL support companies who CAN understand the code (many of whom are PGSQL contributers) and fix it for you.
If this is really an issue (to the GP), they should purchase a support contract and/or buy one of the commercial builds of PGSQL (Greenplum, Pervasive, Mammoth).
I honestly don't know many DBAs myself who could fix the actual source itself.
I feel your pain. The next project I have in our DR process is getting our warehouse PGSQL replicated offsite. Right now I think the easiest way to do this is going to be to use drbd and mirror the disks over the WAN. I don't like it but I just don't feel comfortable with Slony-I yet.
IIRC, they are trying to get Slony integrated into the mainline build. The nice thing about MySQL replication is that it doesn't require any schema changes and replicates objects as well as data.
Actually I didn't want to agree totally simply because I've not had time to read up on anarcho-capitalism. I'm a free market guy and capitalist "pig" dyed to the wool but I think some areas I would disagree probably relate to environmental issues.
Example, in Georgia right now, we have a developer (land not software) who is in the state senate. He's introduced legislation regarding land use that basically says a land owner should be able to put whatever he wants into a waterway (of any size) because it's on his land.
The problem with this is that things like water and air are not self contained. Sure you can build a dome and pollute the air in that dome all you want but ground water and watersheds don't just exist on your property. Some of those ideas would go against some pure capitalist's ideas of government intervention. I also believe that in several areas, we should err on the side of caution because some things don't present themselves until 40 years down the road.
Sure Mr. Plant owner, dump all the mercury you want in the river. There's no problem with that.
I'm facing an issue at my house right now with air quality. My new neighbor smokes like a chimey. Now I've got no problem with people smoking even though I think it's stupid and self-destructive but the problem is that he smokes on his side porch which puts his fumes right into my upstairs bedroom window.
Now this is his property he's smoking on but it's coming on to MY property and costing me money (can't keep the windows open during the mild temperature days because the smoke irritates me and my wife so we have to run the AC instead).
I'm all for property rights as long as you can keep it on your property.
So in that sense, I probably deviate from most pure capitalists because I have no problem with the government telling this guy he can't smoke outside. I also wouldn't a have a problem with the government telling me I can't grow X/Y/Z plant on my property if the chemicals I used to keep the critters off the plants was getting into the groundwater.
I agree for the most part. I appreciate the attitude Fluery has. It's the same model as RHAT and any number of open source companies. I can't stand this ideal that "making money" or "getting rich" is wrong somehow. Sure you can blast JBoss for not being entirely his invention but you can't deny the visibility he's brought to it.
Why a mouse? A mouse is not a home theater device. Why another input device at all? Do you know how many freaking remotes I have right now? I'm in the process of ripping my dvd collection so I can just use my Show Center remote and be done with all the others. Besides, when you start adding the storage you will need for the Mac Mini and the redundancy so you don't have to rip your stuff all over again, your little Mac Mini is a full blown setup better suited for an office not a living room.
Easy. Anything based on the SigmaTel chipsets. Pinnacle Showcenter (pretty cheap for an unopened model 1000 on ebay) is what I use but every vendor has a device based on it now. Here's the short list:
Here's the thing people. Most users already have computers in the home office somewhere. To tell them they have to buy a $500 or $1000 dollar media center pc that is louder than any of the other components and larger to boot kills most purchases.
I've had been debating a media center pc for over a year. Finally I heard about the devices based around the SigmaTel media chipset. I bought a Pinnacle Showcenter 1000 for about $100. IT handles all the movie files I have (excluding the DRM ones which I don't have any of). All you have to do is install the media server software on your PC.
Now that's the typical end user. My rig is actually different. I run Oxyl Box for the streaming server portion on a my Linux server that has a 800GB RAID 5 under it for storing all of my media. What happens the first time the Media center PC has a drive failure from cooling issues? Now you have to have a redundant setup on the media center which increases heat and noise. Joe Blow isn't going to rerip his ENTIRE DVD and CD collection the second time around.
The Showcenter even includes wireless. Now what's easier for the "typical" home user? Installing a media center PC with all its warts or being able to move 2 devices and have your media in any room you want? All you need is a power outlet. You don't even need a cable connection. Your PC can do all the recording and streaming of live TV (with a TV tuner of course) and you need your streaming appliance and an output.
I imagine that some smart vendor will eventually integrate these into the TV itself. I can see my next TV being one with either Wireless or Ethernet out the back and software installed on the PC I already have.
I would gather the reason you see that is that Joker is the cheapest on the block. Unfortunately I had to move two of my domains this weekend because of this. I just took a site live for my inlaws rental property and couldn't have it down.
What really annoys me is that Joker didn't post anything until two days later. When I COULD get to joker.com, I found nothing at all about the attack. It wasn't until Saturday that I finally got some information. The attack had been going on since Thursday that I know of.
I've had over 20 domains registered with Joker and I've always liked the proccess. Unfortunately, I couldn't afford them to be down.
I'm just curious if the attack was directed at joker or a domain they're the registrar for?
We use fanout to run wsadmin.sh and deploy apps across our WebSphere App servers. We were using the NDM but found custom scripts to be much more reliable. It's really handy for JspBatchCompile.sh as well.
Fanterm is just FUN. run fanterm against a list of servers and see how much.
Perfect example. We *WE'RE* running DB2 UDB on RHAS 2.1. Every so often there would be a spike in load average where all activity on the system would be blocked. It would only last a few seconds but the backlog would take 5 or 10 minutes to clear up. After speaking with IBM AND Redhat on the issue, it came down to a vm flushing issue. The VM would flush and in the process block ALL system activity WHILE it was doing this. It only happened under VERY high loads and only on large systems (ours was an 8-way 16GB x445 server)
Should I have been expected to fix it? I'm not a kernel developer and I don't even play one on TV. I'm a Systems and Network Administrator. I called Redhat and they provided us with a fix for the problem. It never FULLY went away since the problem was all in the algo that handled the vm was redesigned in the middle of the 2.4 series. Upgrading the kernel wasn't an option because we had to have a specific redhat kernel for our SAN drivers to stay supported.
I was glad I had Redhat AND IBM to call that day because it meant that I didn't look like an idiot when explaining to my boss what the problem was. The intermediate kernel fix was enough to get us stable again until we could upgrade RHEL to version 3. We've since migrated that server to AIX but even there we run into issues that IBM has to provide the same kind of fixes (this is to remind anti-linux people that even commercial OS' have bugs).
Or maybe it's good for people like us who buy RHEL for commercial products that require it for support but want to keep the same distro across all our other servers.
I have to have RHEL for Websphere but I don't have to for apache or for samba where we aren't installing a commercially supported product or need a support contract.
My wife and I both own copies of Lux. It's probably one of the coolest "simple" games we've played in a while. It was really nice to finally have a Windows version when I built her system.
This is probably my biggest concern when interviewing people for System Admin positions. Ethics that is.
We end up having power over everything. We have the ability to read everyone's email, look at everyone's personal files and in some cases screw the company out of millions of dollars. And we know the ways to cover our tracks because we know the environment better than anyone.
I know that I would never abuse that position but it's tough trying to decide based on interviews if someone else would. It's the thing that keeps me up at night when we bring a new person on board.
Considering I work in a highly regulated industry (lending), our developers learned from the previously design system in terms of rule-based systems.
In our case we call it a "product". Each product has an associated set of rules such as interest rates, loan term and more. When we face regulatory changes, we modify the "product" but the original loan terms are stored at the time the were done so we can always go back and show you the state of a loan at any point and time.
It also helps that we actually have a data warehouse that contains the same information.
"I'm sorry, but if every politician's entry would be "factual" and simply lists "Signed X into law on X/XX" type of information then what's the point of an encyclopedia?"
That's EXACTLY what an encyclopedia is...a fact book. At least in my opinion.
*YOU* as the informed citizen need to aggregate all the facts and determine yourself what was in the law and who was affected. That's your social responsibility. It honestly sounds like you need someone to provide "glamour" and "spice" for you. No offense.

Actually, it's interesting but IBM just certified DB2 UDB to run on Ubuntu:
http://www.ubuntu.com/news/db2cert
Someone's been reading Darwin's Radio.
If you haven't, maybe you should. He extrapolates the idea of sudden mutations into two whole books.
Geronimo wasn't certified until IBM got in the mix. JBoss was there first.

The problem is that it WASN'T functional until Saturday. And you still need to have a DNS server to use. If you don't have one you're screwed.

Diskpools and very large ones at that. Doesn't address the offsite issue but it's still a nearline backup.
