Wouldn't DNS blacklists be something for you? It would certainly solve your load problem. There are a couple of providers who can provide the lists commercially for heavy load mailservers.
The combination of 8 DNS blacklists, Amavis and Spamassassin works very well. I used to get more than 300 spam mails per day (intercepted by Spamassassin), due to the use of DNS blacklists I now only receive about 15 spam mails per day wich are intercepted by Spamassassin. Only about 3 spam e-mails per day actually make it into my mailbox, with zero false positives.
The good thing about DNS blacklists is that the spam e-mails are actually rejected in the mail protocol, therefore it will hit spammers directly and renders their spam bots useless. The blacklists also reject dynamic ip addresses, which are all virus infected home computers.
The most effective blacklists I use: spamcop.net uceprotect.net (L1, L2, L3) spamhaus.org (sbl-xbl)
Why don't they just sell it commercially as a generic device with a healthy profit margin and a one month warranty? I can see numerous applications for these kind of low cost devices, you could use it as a navigational device, router/firewall, reading books etc.
If they'd just make it look decent without the weird colours, drop the power handle and sell optional car power adapters etc..
The good part for them is that the profit can be used to deliver them to the 3rd world countries. Also, a lot of additional software would be developed for the device. If it's any good I would buy it for 200 Euro's just for experimenting with it and doing fun stuff.
I think they are aiming much to high at this point.. Also by marketing it purely as a 3rd world equiptment, generates the feeling that it doesn't live up to the 1st world standards.
Quote: "they'll pay 0.01c per kilobyte" That's 10 dollar per gigabyte! And who is going to pay apple for delivering the service? You are! 1GB costs less than 1 dollar right now, can you see the increase in costs? If you want no redunction in service when streaming a movie, you should get a decent internet connection. I promise you, it will be MUCH cheaper in the long run.
Net-neutrality needs to be guarded, or internet providers will implement a pay-per-type-of-usage system. In which case you will get charged extra for making a VPN connection to your work, because you're using it for business purposes.
Next thing, the RIAA will stalk the internet providers, forcing them to pay up for all bittorrent traffic. Also, google video will get so expensive that they'll have to cancel it or switch to a subscription based system.
Please remember that the end-user (you!) is going to have to pay for this all! After all, there is no such thing as a free lunch.
Next thing you know, you will be telling to your grand children how great the internet used to be! Back in the days, it didn't matter what you did on the internet, all traffic cost the same and you had only 1 fixed amount you had to pay!
Why will it turn out this way? Because company's will always maximize their proffits, given the chance.
Also, there are enough possibilities to get faster/guaranteed data transfers between certain points as it is, i.e. leased lines. Do you remember how -EXPENSIVE- they were?
The EU should force them to mention it in their advertising when they shout it out for having such a reliable OS. Since the advertising is in great conflict with the EULA. Just like the "Smoking can cause cancer": "Using this or other Microsoft products can cause critical data loss, system instability and significant loss of profit for any reason, Microsoft accepts absolutely no responsibility."
That's the reason I also mentioned another example.
While the big ERP systems support Linux as a client, our ERP system only supports Linux as the server.
I am sure that they could make a Linux client application without too much effort, but you need to be quite a large customer to be able to force them to.
And Linux migration on the workstation would need to be high on the management's list in order to do so, which it isn't.
Also, even if the ERP problem is solved, there are plenty of other applications to migrate: Autocad, digital catalogues for vehicle repair, banking applications, etc etc.
But if you're saying it's all so easy, I guess your company is already using Linux on the desktop?
You can make the entire discussion as complex as you want, but there is only one reason why Linux doesn't succeed on the desktop market:
Most commercial application are written for Windows, among them are a lot of specialist applications like ERP systems and to name another example "analysis software which interoperates with an advanced metal detector to detect explosives in the ground".
With these kind of applications you can't just switch to an alternative, because there are just too few that match your needs and often NONE of them support Linux.
The only way for Linux to succeed in these kind of settings is to make Wine work flawlessly.
While Linux suits my home needs and server needs -very well-, it's useless on the desktop at the company I work for.
Quote: "Maybe in user interaction. Perhaps, once IPv6 is used now and then, that second dns query will cause an extra 100 ms delay on top of the first 100 ms delay for the first dns query.. causing a human-noticeable slowdown after clicking a link."
I am using IPV6 here at home with Firefox on Linux. I have not once noticed a slowdown, also because everything gets cached.
Having used "host -v -t aaaa www.sixxs.nl" I can see that a DNS lookup takes 53ms when it's not cached (first page), and it only takes 2ms when it's cached (following pages).
Quote: "For example, if a lookup takes 1/10 second, it will continue to take 1/10 second until there are 10 requests per cpu per second."
The amount of time a DNS lookup will take, is just a few nano seconds. Almost all of the delay in a DNS lookup is in the round trip (the time it takes to transfer the UDP package over the internet forth and back). An average home computer can process thousands of lookups in 1 second (if it would be a DNS server).
So in contrast to what you are saying, DNS servers usually have a very small load. For every web page you view (100KB), generates as much bandwidth as 500 DNS lookups. And since DNS zones are often not that large, this is a very simple task for even the oldest server.
Even if the DNS loads would double, this would only cause problems in VERY RARE cases.
Also, take in mind that the typical user does not have an IPV6 router, in which case Windows will not do the extra lookup. And for the root DNS servers it doesn't even matter! Since all of the information is cached anyway with the first request. While the DNS server responsible for the domainname ns1.slashdot.org (example) is only very lightly loaded anyway (see calculation above).
Therefore there isn't a real issue anyway, since the DNS load will only increase with a *very small* fraction of the total DNS server capacity.
KDE is actually quite fast and snappy.
I am running in on a Athlon XP 2600+ with 1GB for almost three years now.
Maybe it's your PC? (memory, graphics card, processor)
Who cares, I could always throw knoppix in the CD drive, chroot and change the password and PAM settings.
Dare to take a chance once in a while!;)
Anyway, it's very easy to make a passwd fallback for root. Point is, since you seldom/never need this fallback password, there is no need to change it.
Been working with Linux for 7 years now, upgrading live servers during office hours. It has never bitten me, although it's not recommended practice either, so please don't call me an idiot. I know what *could* go wrong, but usually doesn't.:) And it beats having to go back to work in the weekends, which I never need to do this way! Weekends are for fun stuff!
Quote: "Besides geek points, why would one want to do this? There is an old saying....If it ain't broke, don't fix it."
Try changing your root password on 10 different servers on a regular basis. Then issue accounts for 55 people on a combination of those servers, depending on which kind of job they do. Also, each of those servers run different services, which some people need to have access to.
This leads to the situation where it is very common for people to have 6 different passwords, and this is the situation I find myself in right now. The situation also leads to a lot of support calls with requests to reset a password, since people find it hard to keep track of their passwords.
I've actually been looking for a solution that is described in the article, but I've failed to find it all out myself within a reasonable timeframe. It's best to start out with a step-by-step tutorial like the article, and then expand the solution yourself over time. So I am very happy with this article!
Depends on what you call "mission critical", if the company relies so much on the data (Telecom and banks) that they will actually go bankrupt if the system is down for a day. Then I would go for the expensive and proven solution. A golden rule is: When you want the best, you got to pay the bill.
But for a smaller company, cost savings are significant if you dare to take a chance. The biggest difference between SCSI and PATA configuration is throughput performance. A PATA RAID 5 is very likely to save your data in the event of a disk failure, just like a SCSI RAID will. And since the disks are very cheap and you can afford a hot spare, why not just replace a drive once in a while? Also remember that there have been rare and unusual cases with SCSI drives dying almost simultaneously and therefore trashing the RAID configuration, so a SCSI configuration is not a guarantee to success.
But obviously, with a 15K RPM rotation for SCSI, throughput is higher. However, SCSI disk space is more than 6 times more expensive. So a PATA raid might be a good solution if you require a bit less performance and higher capacity.
I believe that the most important thing in any storage solution is the controller, since this is the technology that will actually need handle the any kind of failure correctly.
The numpad make numerous tasks so much more efficient you wouldn't believe it: - Doing calculations on the calculator - Working with spreadsheets - Entering IP addresses (This is the only point where IPV6 is going to suck) - Entering any decimal number
People doing finances or network engineers are handicapped without the numpad! Try entering 192.168.1.1 with your right hand, I have just entered without looking at the keyboard in 1.5 seconds.
I believe you should just learn to work more efficiently on your keyboard;)
looks like someone has actually written something usefull about it. Remember the usual thousands of pages of garbage company's often hand in to stall the courts?
Your computer parts are often interconnected in serial, which makes it sensitive to fraud. In my suggestion, the modules are independent and connected in parallel to the buttons.
Isn't the most safe option to have 3 separate company's develop -one- machine?
- One company develops the casing and only uses old fashioned electronic push buttons. - The other two other company's each develop a counter module which are both connected to the same buttons.
This way, the final results should match. If they do not match, the device is broken, or one of the two company's are attempting fraud. By keeping the push button system simple, the connections to the counter modules can easily be veryfied by looking at them.
If the whole thing would be sealed and shielded by a glass plate and the wires would be clearly marked, everyone could in theory check the correctness of the machine.
This way, for fraud to be commited, the three company's would have to work together which is more unlikely. Also, it is possible to prevent the company's from getting in touch with eachother.
A very important point here is: Keep it stupid simple.
IMHO is it very sad that something like this gets modded insightful. I believe that if everyone would just act more professional, it would create a better/more attractive atmosphere for women to work in.
If you want to find a nice girl, go to a bar, lose the obsession and act normal.
So Mr. LinuxDon, I hope you are full, because I just fed a Troll.
I think this statement is more of a troll then my entire message, but I'm going to respond.
Free/busy schedule -- let it run on an external server (perhaps even to show which members in a company group/team are away/busy at once).
Which is a huge overkill if you just want to let people know you are not availiable on mondays for example!
Also, how can someone find that information without receiving the exact URL from you?
business card --? Its called a website, no phone required.
So, I've actually have to use google to find your website when I merely have your phone number. Then I will have to download the vcard file from you website which most people don't have and then I have to transfer it to my phone by bluetooth.
Also, setting up such a full bloated website takes you a day to create it since it's just an overkill for the particular purpose I was talking about.
All in all, it's not nearly as usefull as the integrated solution I was talking about.
Why do i run my own webserver? Simple, I don't want the advertisments that free websites usually have. I will never run a webserver on my phone.
This sentence makes clear that you are also seeing the mobile webserver as a replacement for your current server, which makes no sense as you have already stated.
Also, you are talking about push technology while running the webserver directly on the phone is about pull technology which introduces new possibilities.
All in all I think your point is pretty weak and a Troll.
It's a shame that everyone instantly thinks about running full blown websites on a cellphone when reading this article.
This technology has many uses: - Having a free/busy schedule accessible to others. - Publishing a business card. - Publishing location information. - Publishing a general description about yourself. - Publishing a form so people can send text messages to you directly. - Instant messaging.
Imagine this: Someone would just have to enter your phone number in his phone, the phone automatically retrieves your complete contact information from your mobile webserver and adds you to their contact list. And, as a plus, they will never forget your birthday because it's automatically added.
In terms of bandwidth costs, this application is very cheap since it would only cost about 400 bytes for the above example. Also the webserver wouldn't get too much hits, since only people who know you will be downloading this information, and limits could be set to prevent huge IP traffic.
At this time, the major roadblocks are: - Lack of a dedicated IP address. (We need to wait for IPv6 to become mainstream) - Cell phone number to IPv6 translation.
If there would be no Network Neutrality anymore, the following could (and probably will) happen: - Netcache has to pay to the user's provider as well as for it's own upload costs it already has. - The user still pays the same amount of money he does now. - There is no incentive anymore to upgrade those main pipes, the company's that want good network performance to the end-user will just have to pay up extra. - PROFIT (For big providers like AOL).
In the end, there will be no (speed) advantage to anyone. Everything will just get more expensive! This is what history should have taught us by now. Network neutrality should be guarded!
I think Bram Cohen is just making a BIG mistake here! (Or he is simple misquoted)
I consider your comment a troll, opening a 342 page document in OOo will still only take seconds, not minutes! Your comment make it very clear that you have never actually used OOo in a serious situation. Also the OpenOffice recovery feature works really well, meaning you will not lose the contents of your 342 page document when things unexpectedly goes wrong. (In contrast to MS Word, which both crashes more often as well as making a mess of your document.)
I can also assume that, if you work with 21 million dollar contracts, you will not be editing the document on a 400Mhz computer which renders your point totally invalid.
Further, while I support both applications (word and OOo) to end-users in the company I work for, I am about 3 times more efficient in OpenOffice. All-in-all this means that you will win the few extra seconds OOo takes longer to load the document, back in ten-fold.
