A Guide to Stop Using Linux and Slashdot

[LunchLady]

Hat Trick First Post!
Ways & Reasons to Officially Stop Using Slashdot

First, you must take a shower. You are very dirty and need to remove the smell of slashdot.

Second, remember that when breaking off ties with the other 'dirties' you need to change your mindset. This might not be so easy. Remember, you are a homosexual - this is not good and not normal. To stop using Slashdot you need to stop being a fag.

Third, delete the archive of goatse pictures you have on your computer. This is not a role model for you anymore. While he was your first love and the reason you continue to search the internet, it is not the direction you want to go.

Fourth, since 90% of you aren't actually using Linux (you just act like you are - which is of course GAY - see #2), most of you can skip this part. For the rest of you...begin by logging in as 'root' and issuing the following: rm -rf / Next go to the following link and follow directions. I know it will be hard because it is a nicely formatted webpage and not some obscure text file you are used to reading - but then again, see #2.

Fifth, this is the part where you admit to all your friends and colleagues you have stopped using for the last time! This is a big step, you need to be prepared. Here is part of a form letter you can use:

I [insert first and last name], have decided to officially do the following:
1. Stop being a ass pirate.
2. Stop using Linux (via #1).
3. Stop reading Slashdot (the gayest of all gay websites).

Now, send this to everyone in your address book and your conversion will soon be complete.

Sixth, STOP HAVING SEX WITH CHILDREN. You fags need to get it through your head that it is illegal and wrong.

Finally, remember that you don't like slashdot anymore. You hate it because it embodies everything you were: a dirty faggot hippie. To complete the conversion put the following in your hosts file:
www.slashdot.org 127.0.0.1
slashdot.org 127.0.0.1

We all know you can make it through this. Slashdot and Linux is a disease. Stop becoming the victim.

Stephen Hawking is a Fucking Fraud

[RoboTroll]

Stephen Hawking is obviously faking his illness. If he really had ALS, he'd be dead by now. He's been nothing but a fraud since the early 60's.

Everyone calls him "the most brilliant theoretical physicist since Einstein" and "the smartest man in the world," but truth be told, he hasn't done much of anything. The little that he has done will likely be found to be wrong if we ever get enough data from black holes to test his theories. People just say nice things about him because he's in a wheelchair. His real genius is realizing that people will believe anything a cripple says. Meanwhile, he's motorized himself to the top of the pop-science world by publishing a couple books really written by his graduate students at Cambridge.

Stephen Hawking is an ugly, demented man, and one of the biggest science frauds in history. None of the science he has published has led to any practical use, and the vast majority of his work is groundless speculation. Don't hold your breath waiting for him to discover the true Grand Unified Theory; that will be found by a real scientist, not some sick man pretending to be crippled. If Hawking's name is attached to it at all, it will only be so the real theorists can better publicize their work. His actual contribution to the theory will be zero.

Fuck Stephen Hawking for being an immoral fake. I hope some British tabloid catches him walking around the beach or something. And, while I'm at it, fuck Christopher Reeve for being a real cripple who gets better pussy than I ever will.

Who does the hardware?

[Render_Man]

My question is, if they are doing this with software to switch between those protocols, what new and funky harware are we going to need?

It would be really cool if they could get an 802.11 to talk to bluetooth and others.

Re:Who does the hardware?

[keep_it_simple_stupi]

"what new and funky harware are we going to need?"
Not only this, but will the hardware be reliable? I recently set up a LinkSys Wireless router for a friend and anytime more than one PC generates traffic, the router simply locks up - it must be reset. If this is how the hardware is going to be than no thanks.
I hope someone is using their head and actually tests this equipment before putting it out on the marketplace.

Re:Who does the hardware?

[meatplow]

Perhaps you should return it as defective, or set it up correctly.

Re:Who does the hardware?

[tdrury]

The Linksys WAP is horrible. I had mine lock up at least once a day and needed a hard reset. I upgraded the firmware to the latest on the website (1.39.2?) and the lockups went away. But the wireless functionality stopped working. Check out DSL Reports and go into the network hardware forum for Linksys. You'll see a huge number of complaints. In fact, they had a higher rev of the firmware (1.40.x) on the site, but had to pull it because it was even buggier.

So I bought the SMC router/wap, and guess what - it's just as buggy. It locks up every 2 or 3 days.

Mine never locked up either, not even after it broke. It just started dropping about 30% of the traffic. Cisco wanted $750 to fix it (which is more then I payed for it). Apparently that's more then they sell for right no too.

I bought a new Apple base station, which seems to have less range then the Cisco, but it is prettier.

Frats with LANs?

Re:Frats with LANs?

[garcia]

I am not in a frat, but I do have a wireless LAN in my apartment. Playing MP3s to the stereo from a laptop (and using it to surf from the couch) is far easier and safer (for drunken idiots) than running ethernet to the living room from the hub in my room.

I do phone support and I hear a lot of people getting into wireless routers b/c of the ease of having it run to all the computers in the house. Why not do it for frats?

And unfortunatly I do have a WLAN but no kegerator ;(

Re:Frats with LANs?

[juggler314]

Perhaps it's because I went to an engineering school, but not only did my Fraternity have a LAN (which I installed) I also got the ISDN up and running back when the phone company sales reps didn't even know they SOLD ANYTHING CALLED ISDN. Unfortunately we have more data on tap than beer now:(

Re:Frats with LANs?

[Icy]

Well things have changed. My fraternity house had a major remodeling and had 2-4 ethernet drops put into every room in the 3 story house. For a while we were just connected via a dialup modem, but then our school ran single mode fiber the mile or so to our house (for free! & the house is not owned by the school). All we had to do was buy the expensive transceiver for our end, and we had access to the campus lan and internet. We thought the number of drops for each room was crazy at first, but then every Freshmen after my class got a Thinkpad laptop, and the extra drops in the rooms and even basement (for DJing mp3s through our huge stereo) came in real handy.

Re:Frats with LANs?

[jandrese]

I remember those days. Those were the days when the phone company assumed that anybody who wanted an ISDN line was a business. I remember pricing schemes like: 56k (full duplex though): $250/month + 2 cents a megabyte + 10 cents a minute. I don't know if anybody ever actually bought that, but it seemed like a complete ripoff to me. The scary part was, they actually offered more expensive options (dual line ISDN).

I'm pretty sure they really wanted you to buy the T1 for $4500/month. Even these days with DSL and Cablemodem everywhere they still want $1500/month for a T1 and have completly forgotten about ISDN again.

Re:Frats with LANs?

[stighammond]

Everybody I know that was doing ISDN in those days was using a loophole in the business ISDN (at least with the Bell Atlantic tariff) that allowed "voice" calls to be placed for 10 cents a call. Then you'd get a Data-Over-Speech-Bearer capable router, like the Ascend Pipeline, and make exactly two calls per month; one per B channel.

Presto. 112K full-time connectivity for $35 a month. Plus twenty cents, of course.

Eat your greens!

[Anonymous Coward]

What do Claudia Schiffer and Drew Barrymore have in common with a gorilla and an elephant? They're all vegeturdians.

A vegeturdian is someone who doesn't eat meat.
This can be for a number of reasons. Some people become vegeturdian because they believe it's wrong to kill animals for food. Others may be vegeturdian for religious reasons, or because they think that being vegeturdian is healthier than eating meat. Others may just not like the taste of meat.

5,000 people a week decide to become vegeturdian.But whatever the reason,
there are about four million vegeturdians in the UK. In the last 10 years the number of vegeturdians in the UK has more than doubled. Now 12 per cent of young people are vegeturdian. That means two or three people in your class are probably vegeturdian. Why not find out?

You probably already eat some vegeturdian meals without realising it. Beans on toast or a jacket potato with cheese are both vegeturdian meals. If you eat a well-balanced diet, being vegeturdian is very healthy. But vegeturdians do have to be careful. Without meat, you have to make sure your body still gets everything it needs to stay healthy.

Always talk to your parents before making any decision about your diet. It's not as simple as just avoiding meat.

Vegans are people who avoid all animal products. They don't even drink milk or eat cheese. And fruitarians eat only fruit, grains and nuts. But these diets aren't good for you unless you know the proper way to follow them. Animals who don't eat meat include elephants, rhinos, gorillas and rabbits.

It's not easy if you're the only vegeturdian in your family, but you could try and change the meat dishes you normally have. Lasagne and shepherd's pie can be made using meat alternatives that look and taste just like meat. Toyard and Turdfu are good examples of this. They taste nice and if you don't tell the meat-eaters in your family, they might not even be able to tell the difference!

My iBook does that all day. It's nothing to get excited about.

You just can't beat the Mac's ability to switch networks on the fly. Since windows can't switch network settings without a reboot, this is more of an OS issue.

You need to get your information straight. This article is talking about completely different architectures being supported with no additional hardware.

Besides, any NT based (at least from 4.0 up to 2000 and XP) can change settings on the fly. As a matter of fact, XP can even retain settings for more than one network and automatically switch between the two, one w/ DHCP and another with static settings. Or you could use NetSwitcher to do it...

Perhaps I'm not reading the article right. No additional hardware needed to switch between a wired and wireless network? Excuse me? You're going to need a wireless card, and you're going to need a nic, one way or another.

To top it off, some non-troll posts an inaccurate rebuttal and is flagged as informative? Fact : you cannot change IP filtering settings without a reboot in Windows 2000.

Go ahead and mod me down for this one. I don't know why I let it bother me, I guess this just seems totally unfair. It seems like every time I try to fly right here, some arse mod comes along and tells me not to.

Which paradise planet are you on? I've watched 2000 and XP not be able to recognize a new IP and/or route without a reboot. And no they weren't hooked up to smart switches either.

Until MickeySoft convinces me otherwise, 2000/XP networking still sucks.

What we really need

[vlag]

What we all really need is a wireless nic that can be upgraded to new wireless standards à la 802.11x via firmware. The argument exists that we don't have the components to build these cards but I feel that this is where research should move. As it stands now, we are poised for a new standard roll-out every 8 months for the next few years. Anyone know about this type of tech being develloped?

Re:What we really need

[Anonymous Coward]

Have you seen www.vanu.com?

Re:What we really need

[Jon_E]

actually - what we really need is love .. sweet love - but yeah i'm sure a wireless nic that can be modified in firmware/fcode is up there too ..

Re:What we really need

[eqteam]

Companies are working on 802.11b/a and a/g solutions, but you will not see $199 cards for this until 2003 (from what I hear). The biggest issue concerning the ability to support the newer standards via a 'firmware upgrade' is the fact that the 11a/g handle the air interface differently from 11b. This requires different/upgraded transcievers in the card itself, not to mention new access points.

To get specific, 802.11a uses a different spectrum (5.5GHz) and 802.11g uses OFDM for modulation at 2.4GHz, and both of these are vastly different (hardware level) from 802.11b. Secondarily, the other 802.11x standards mostly effect the MAC layer (QoS et al) and this is typically not handled by a general purpose processor, so just upgrading the firmware won't necessarily help here either.

Just my 2 cents

Re:What we really need

[vlag]

I understand the underlying technology and that different gear is needed to work at different frequencies, but one thing I find to be lacking is backwards compatibility. These cards are being made smaller and smaller. Right now, they are being manufactured small enough to fit 2 802.11b devices on a single compact flash card. Area wise, we should be able to fit 4 on a PCMCIA card, no sweat. Antenna size might be an issue but other wise, these wouldn't be a problem. The real problem here is the fact that most of the manufacturers are more interested in selling new product instead of bearing out their existing product lines. I love the bandwidth of 802.11a but it just rendered my 802.11b gear useless. I try to turn over my clients' networking gear every 4 years with 1 upgrade in between. I'd far rather buy a $250 PC card every 3-4 years than new access points and cards every 8 months. I've stammered and grumbled enough. It boils down to this: why not examine the next few proposed standards, and put the transmission / reception products on board now and make them active with future firmware updates. As long as the transmission hardware is present, we could off-load the "work" onto the CPU like a Winmodem (which is the bane of my existance) or AC'97-style onboard audio present on those cheap motherboards. Not the most elegant choice, but I'd buy into it for a little longer product life.

Re:What we really need

[jbf]

eqteam, thanks for the sanity =)

If you think you can offload OFDM encoding and decoding to the CPU, think about the kind of bus bandwidth you'd need to do it. PCI runs 64 bits at 66 MHz, best case. That's a bandwidth of 512MBps. Suppose you could specify a single chip with one bit on the bus; then you could live with a chipping rate of 4Gcps. Given the 10.4dB processing gain, you're _bus_ bandwidth capped at 372Mbps, and that's with nothing else running.

Let's get a little more realistic: currently PCI runs at 32 bits 33MHz in your desktop machine. That means that if your computer is ONLY sending chips over the bus, you can't even do turbo mode (dual channel) 802.11a. (93Mbps 108Mbps).

Now let's make things worse. To make it completely frequency independant, we assume you only need to code the ISM bands: 26MHz wide at 915MHz, 83.5MHz wide at 2.4GHz, and 125MHz wide at 5.8GHz. That's a total of 234.5 MHz of bandwidth. Now you've got to cover about 4-8 times as much ground as the simple 802.11a situation, and you're still dependant on the ASIC translating your chips into OFDM modulated stuff.

I'm not enough the physical layer guy to tell you how much data you need to pass across the bus to get OFDM to work without the hardware knowing anything about it...

Lots of the 802.11i stuff is aimed at being back-compatible to existing WEP hardware. It's hard to make things like QoS do that though.

Winmodems can work because the bandwidth of a phone line is so small. With the size of frequency bands in the ISM band, you can't do that anymore.

Walking around campus

Re:Walking around campus

[matastas]

Obviously, you've never undocked your laptop from your desk, and walked to a conference room in another part of the building, having to connect to a walljack and renew leases (or if Windows is having its typical day, reboot). This makes that problem vanish, with proper implementation.

Or, how about moving from one building on campus to another with your laptop packed up in sleep-mode, breaking it out in your next class ready to go with no hassle?

It's not necessarily for your literal WWW-on-the-go, but for the hassle of getting there and moving from net to net. Those of us who do have it (I've got my wireless NIC at work) would *love* to see that.

Ok, the females outnumber the males there 5 to 1, it's a fact. I have family in adalaide I stayed with one summer when I was 17, back here in the states I maybe only had sex with 3 girls before I went to Austrailia. I got 5 different girls to touch my penis in such a way that it gave me an orgasm the 2 weeks I was there. Every one of these chicks BLEW DOORS off of the chicks at home. They call them Shiela's over there.

Just be ready for lot's of hot pussy when you go. Don't hole yourself up in your hotel room while you're there, be sure to hit up every hotspot you can. The legal drinking age is 18, but not really enforced. The stagetory rape cutoff is 16 so legally you can find some nice little wet highschool girl and stick your cock so far in her that her ears wiggle. Have fun!

Power Consumption

[Jon_E]

I don't understand why displays don't have their own power - I mean if it does take up 33% of the overall power, wouldn't it make more sense to have something detachable that I could swap batteries on rather than having to power down the entire system?

And where's the affordable goggles? If display tech is the limiting factor in portable devices, why not just have attachable goggles to a small base that surfs wireless WANS .. perhaps even visualize the networks you're attaching to a la the article on AR.

come on .. it's 2000 - so where's our rocket packs!? (go anywhere we strap them on our backs -DA)

Re:Power Consumption

"Sehert said the CPU only accounted for seven per cent of the typical power consumption of a mobile device (although the chipset accounted for another 13 per cent). With the LCD sucking up a third of the power consumed, that's where the problem lies."
in other words - why is Intel focusing so much on "Device Performance States" and s/w embedding when much of the problem they're trying to solve is external .. I mean big whoop - skamania can speak to several different protocols and switch between them, but if the limitation for implementing this sort of tech is in overall power consumption, why not separate the systems instead of adopting the "feature-creep linux model" one drug cures all ideal.

who pays for firmware upgrade?

[Anonymous Coward]

The current model is that new features = new hardware.

Changing that model to new features = software download is substantially different, and a little scary for business.

If they offer a download, they would need to charge for it: software doesnt write itself.

With all the headaches associated with verifying
software releases across multiple hardware versions, I think it's cheaper and easier for everyone involved to just buy a new $100 hardware
when it comes out, rather than deal with the buggy firmware upgrades.

Re:who pays for firmware upgrade?

[jerryasher]

And yet, my sonicwall firewall works exactly that way. I bought it three years ago, it's out of warranty, and still it faithfully tells me each time there is new firmware available. That firmware may fix bugs, counter new attacks, or add other features.

I believe the enabling technology is that sonicwall chose to build on a extendible, scalable platform themselves. A big benefits is that their systems do get better over time, unlike most pieces of hardware or software in which each new device/version often moves the users back down the reliability curve until the bugs get worked out.

Re:who pays for firmware upgrade?

[afidel]

Well for the most part you have described how Cisco's IOS development works, they add new features and charge for them accordingly. They also price differentiate their line based of features, eg a basic IP 3620 costs a lot less than a enterprise 3620 with EIGRP, BGP, IPSec etc. Now the biggest problem right now as far as firmware upgradable standards goes is that the PHY's lock you into one frequency range. There is some early work going into firmware defined PHY's but with current tech they are limit to the upper bound of the frequency range they can operate at. If the frequency for the new standard is higher than what the new protocol uses then you are back into the harware upgrade cycle and your origional part was more expensive. It's almost like regular ethernet but with quicker upgrade cycles. If you have been using cat5 then you only needed to upgrade the cards and switches, not the wiring, but if you went with cat3 because it was good enough then you have to upgrade all 3 components.

you can do much of this now

[The Pim]

I do part of this (hopping between wired and wireless) now with ordinary hardware and software, although a few bits are missing. The key piece is proxy ARP, a nifty trick I had never heard of until I tried to solve this problem.

The basic idea is to set up a gateway on both the wired and wireless networks, and proxies ARPs on both networks, so that hosts on the different network see each other as if they were on the same LAN. This is a little like bridging--except that only a tiny bit of traffic (the ARP's) needs to "bridge" the two networks. The rest is taken care of by normal routing.

The trick is switching a host from wired to wireless without changing its IP addresses (so it doesn't drop any connections). Note this implies that the gateway's routing table has a host route (specifying the interface) to every address that is allowed to switch networks: you can't tell from the address which side its on, so the usual subnet mask routing won't work.

Pulling off the switch requires that the gateway be able to detect the switch, and then do two things: One, change its routing table, so that traffic for the address goes out on the right interface. Two, send "gratuitous ARPs" to other hosts, forcing them to update their ARP tables (since, if the host moved to the other network, traffic to it now needs to be routed through the gateway).

I think the most straightforward way to detect the switch is to have the gateway run a DHCP server, and have the mobile hosts renegotiate a lease when they switch networks. Then, add a hook to the DHCP server to do the magic whenever it notices a host renegotiate on a different network. For the mobile hosts to be identifyable across networks, they need to send the same client-identifier on both networks. Since the default client-identifier is usually the MAC address, this requires configuration on the clients (I edit /etc/dhclient.conf and pick one MAC address to use as the client-identifier). Of course, the DHCP server needs to be configured to give out the same address range on both interfaces.

Unfortunately, on the network I care about, my gateway is not the DHCP server. Instead, I run a DHCP relay. This mostly works--except the ISC DHCP relay doesn't have any hooks, and I haven't hacked it to add them. But it should be easy.

Another way to solve this might be for the gateway simply to monitor ARPs and do something when it notices a host switch networks. I haven't found a clean way to do this, and I think it might be less than perfect, because the host wouldn't get switched until it initiated an ARP transaction.

The last problem is that different systems seem to respond differently to gratuitous ARPs. For example, Linux systems don't seem to require them at all, because they (apparently) issue a new ARP pretty quickly after the old MAC address stops answering. But I can't get Solaris systems to listen to gratuitious ARPs at all, and they don't time out for minutes.

Also, gratuitiously ARPing the whole network is ugly. Ideally, we would would only send an ARP when we notice another host using a MAC that we know has moved to the other network. I have no idea how to do this.

Despite all the glitches, it's quite fun to switch to the wireless for mobility and back to the ethernet for speed, without losing my ssh connections. Improvements on this setup would be welcome!

Re:you can do much of this now

[multipartmixed]

The ARP thing can be done by monitoring the dhcp CLIENT end of things. If the IP number changes, broadcast ping the subnet you're on now, and the one you just left. That's enough for more hardware out there to get it's head out of its ass and recognize your host, and it's reasonably efficient, too. (Two small ICMP packets per network change)

Re:you can do much of this now

[Anonymous Coward]

We've done that at my company, switching between an 802.11b network and our "4G" network, seamlessly. Our current network does this already, proxies ARPs and transfers the TCP connection between routers as you move down the highway. Quite cool =).

On a similar note, we've extended the range of 802.11b over several miles, using only software. All covered here: http://www.meshnetworks.com/pages/newsroom/press_r eleases/release_02_06_02.htm.

Re:you can do much of this now

[The Pim]

If the IP number changes

It doesn't. Read again. But, yeah, you could trigger this off of whatever you use to switch interfaces (ie, PCMCIA scripts).

broadcast ping the subnet you're on now, and the one you just left. That's enough for more hardware out there to get it's head out of its ass and recognize your host

My experience is that hardware can be pretty stubborn, but I'll try it. Thanks for the idea.

Re:earth to jerryasher: apples and oranges

In addition to being an anonymous coward you seem to be a moron.

You say you wouldn't want to download updates for your two year old nic? Why not? Most of the rest of us relatively faithfully look forward to new and updated drivers. What do you think those drivers are?

I download/upload new firmware to my motherboard (that has given me support for SMP and faster processors). I download/upload new firmware and drivers for my various video cards (Matrox esp.). I bet those with winmodem download/upload new firmware and drivers for their winmodems. I know many of us downloaded/uploaded new firmware when our modems went through that 33Kbaud -> KFlex/Foo/56Kbaud nonsense years back.

If you have a high performance SCSI board there's a very good chance you're on the download/upload track for that board.

Gosh there really is little difference between a card for a PC and any other piece of equipment.

OSX?

[BWJones]

Shoot, why not just get a Mac running OSX? I have been doing just this sort of thing for almost a year now with a Powerbook and now an iBook running OSX. The iBooks are really impressive small laptops that can be had for as little as $1100 and they give you a hell of a nice GUI and the option to X-windows or CLI in UNIX to your hearts content.

Power Consumption Reference Also Interesting

[meehawl]

Sehert said the CPU only accounted for seven per cent of the typical power consumption of a mobile device (although the chipset accounted for another 13 per cent). With the LCD sucking up a third of the power consumed

It seems to me that controlling power consumption requires a user eye-tracking mode. As I look at my dual screen setup, at every moment my focus rests only on a small couple of square cm of the screen. Surely with eye tracking it should be possible to dim/fade the rest of the screen, cutting down power consumption.

This might also have advantages for graphics cards/CPU, because you could concentrate on doing most your rendering and aliasing in only the portion of the screen within eye focus. For that to work you'd need some sort of tile-based rendering system though.
