How To

When it comes to home computers, k.i.s.s. and forget it

I’ve been learning a hard lesson these past few weeks, as my parents go through a time of computer trouble, and since I’m the one who purchased their computer equipment and set up their network, it’s up to me to get things right again.

What’s the lesson, you ask? As encapsulated in the title of this post, and as I’ve been yelling it at myself in quiet moments, it’s: keep it simple. 

Here’s how their setup looks:

  1. Cable internet connection
  2. Wireless router
  3. Vonage box hooked up to router, in turn hooked up to phone w/ answering machine, and multi-function printer/fax/copier/scanner
  4. Same multi-function printer/fax/copier/scanner also hooked up to router because it’s networkable
  5. Older desktop hooked up to router, another printer through parallel port, and to the multi-function machine through the network
  6. Laptop with wireless card, using the wireless router, configured to the networkable multi-function machine through the network

Where should I begin? Gee, let me start with WPA. Why? Because that’s how I had their wireless router set up. And every time something happened with the connection, they either couldn’t find the passphrase, or for some reason the laptop’s card didn’t feel like connecting to the router. Lesson learned: ditch encryption, just set up MAC filtering. That way, they can connect on the go, and don’t have to bother with WEP or WPA, which is a real hassle unles you’re a geek. Plus, with MAC filtering, unless someone can spoof a MAC address, they can’t connect to the network. And if they can spoof a MAC address, there’s a good chance they know how to get in even if encryption is enabled. Yes, I know the traffic can be sniffed if the encryption isn’t enabled, but who cares? Even WPA encryption can be sniffed and decrypted with readily available utilities. So why bother with it?

As I banged my head against the wall, I rued the day I set up their multi-function machine through the network. Why? Because if you have to delete it and re-install the printers, or you have to re-format the OS (Thanks, Windows, for the crappy OS, and thanks, driver manufacturers, for the horrible, latrine-worthy job you do writing those drivers – for all devices, not just printers!) you can never find the machine on the network so you can re-configure it, and you spend hours re-setting it to factory defaults through the printer’s LCD menu, then hunting for it on the network. Have you ever tried to walk someone through a printer’s LCD menu when you can’t remember the options, and they’re not familiar with it? It’s not fun. Lesson learned: install through USB, and set up local printers.

Quick question: if you unplug your printer’s or computer’s network cables from the wireless router, can you plug them into the IP telephony router? I guarantee you your parents or friends won’t know the difference, and they’ll plug them into it, then wonder why they can’t get on the Internet or connect to their printer. Lesson learned: forget IP telephony devices like Vonage. It may be cool for us youngsters to brag about how we slashed our phone bill by switching to Vonage or just using Skype, but it’s not cool for your parents when they can’t receive phone calls or faxes. (Yes, I’m talking to you, Vonage, with your awkward and arcane programming steps (or rather, button dances) so I can get my printer to send/receive faxes through your connection! Forget that!) Just set your parents up with a dedicated fax machine, plugged into a wall phone outlet, then sit back and relax, because they won’t call about it! And it’s the same with the phone! Leave it plugged into the wall! Forget saving $5 or $10 a month just for IP telephony. It’ll cost you and your parents much more in stress when their phone doesn’t work.

When my parents lost data because their laptop crashed and had to be reformatted, I realized the value of setting them up with automatic, regular data backup, the kind that just works. You know, you don’t think twice about setting up backups in the server room, but somehow you think the data on your laptop or desktop will take care of itself… Unfortunately, Windows doesn’t come with an easy backup program. Lesson learned: buy a big external hard drive, and set up automatic, regular backup jobs to it. It’s preferable to get a drive that comes bundled with a backup utility. Have any of you used the Windows Backup utility? What a stinker! How do you edit scheduled jobs? First, you can’t edit their every aspect after you’ve created them, and second, who’d think to look under a completely different app, called Scheduled Tasks, to find them there? Really, would anyone other than a geek know that? Why in the world aren’t the jobs available for editing within the Backup utility? It’s just plain dumb design.

As I had to re-educate my parents about the various ways of doing things on the computer, I came to realize (duh!) that I should have spent more time training them at the outset. Yeah, it seems like a no-brainer now, but back when you’ve just spent a couple of days transferring all their stuff and settings from the old computer onto the new one, do you really feel like spending another half day training them on the new machine? No, you just sit them down in front of it, point out the highlights, and tell them to enjoy it! Well, you pay for it later. Lesson learned: spend time training the user at the outset – you’ll avoid problems down the road. And define simple pathways for them, stuff like:

  1. This is where you save your documents.
  2. This is where your email archive gets stored.
  3. This is how your email account is set up. Make sure the settings stay this way!
  4. This is how to back up your bookmarks.
  5. These are the passwords and simple access instructions for the firewall, router, computer accounts, etc.
  6. This is where the photos get stored. Use this application to manage them. Download the photos from your digital camera this way…
  7. This is where the music gets stored. Use this application to manage it. This is how to sync the iPod…
  8. This is where the videos get stored. Use this application to download the videos from your camcorder to the computer. Here’s a simple way to make a DVD from a video…

It’s stuff like this that saves you countless headaches. If you need to, make screen-capture movies and put them on a “how to” DVD for them. Or write instructions, with screenshots. But make it simple, or you’ll pay for it!

Finally, as I troubleshooted why the laptop kept crashing because of obscure driver errors (everything was up to date, and the latest driver versions were installed), I learned the following three things:

  1. Buy a good brand. Don’t get a cheap brand. My parents have an Averatec laptop. That thing clonked out from the start. It was supposed to be able to output video to a TV through an S-video port, and it wasn’t even able to do that. When I called Averatec support, their advice, right off the bat, was to reformat the laptop. Great, the panacea fix used by all lazy tech support people! Then, after the 1-year warranty expired, it started to crash unexpectedly, even though there were no viruses and no spyware on the computer. It didn’t have any weird applications installed, either, just mass apps like Office, Firefox, iTunes, Picasa. So, don’t buy Averatec.
  2. Get an extended support plan. Don’t get cheap when you shouldn’t! Get that support plan, and make sure it includes accidental damage coverage, as well. You’ll be thanking yourself when you have someone to call if the hardware goes bad, or you need help with the system.
  3. Don’t buy Windows. Sounds harsh, doesn’t it? But it’s true. People who aren’t geeks need a simple operating system that’s not fragile – one that doesn’t crash or is susceptible to hundreds of thousands of viruses and malware. Windows may be good for developers who are shackled to it by the work they do (like me), and it may work fine at the office, (where you have a Help Desk department, and you’ve got an industrial-strength firewall and anti-virus thin clients pushed out to all the client computers, with the latest virus definitions,) but it’s not good at home – not for people who are at a loss when they need to tell a bad file apart from a good file. The choice becomes pretty simple: Mac OS! Just get a Mac for your parents, or tell your non-geek friends to get one. Then, when they don’t call you to complain that it keeps crashing, you’ll get some time to pat yourself on the back.

I hope this helps you streamline your work as you set up your parents’ or your friends’ machines. I sure wish someone shoved this under my nose when I started to set up my parents with new computer equipment.

Part 3 of the RIP Act coming soon for the UK

The UK Home Office has decided to put through the 3rd part of the Regulation of Investigatory Powers Act. Originally introduced in 2000, the first two parts have already been implemented. This particular part would introduce penalties of up to 2 years in jail for companies or individuals who wouldn’t disclose their encryption keys at the government’s request. The final language may be amended, since the Home Office is involved in a consultation process on this matter, and results have yet to be reached.

As usual, the Slashdot people are having a field day with this bit of news. Even the language used by reputable news organizations is sensationalistic. I have to admit I was concerned, but I had a look at the wording of the act, and it says, clearly, that organizations or individuals would only need to release their encryption keys at the specific request of Her Majesty’s forces, for a pending investigation. It’s not as if the government’s asking everyone to hand over their keys, en masse. They’re also going to reimburse them for their expenses of retrieving and reproducing that data.

To me, this is no different than the powers of search and seizure police have here in the States. They can obtain a warrant to search your property, and you can be sure they’ll go through with a fine tooth comb, looking for anything important. On top of that, they won’t reimburse you for the trouble.

Well, now they’ll be able to do the same to someone’s data in the UK. Until now, encrypted data was above the law, so to speak – if it was well encrypted. If RIPA-3 gets going, the police might have a chance to take a look at it. I say “might”, because encryption can use constantly changing keys, and if you forget or misplace the original key, good luck getting that data back…

Service remotely encrypts or deletes data

A new service called Everdream allows you to encrypt or delete computer data if it’s stolen. The computer will contact the Everdream site the first chance it gets, and it will get its directives from there. It’ll also store the internet connection information for law enforcement purposes. Cool! Unfortunately, if the hard drive is reformatted before it’s connected to the Internet, Everdream is useless. See, this is why flash memory storage should be standard on motherboards, in addition to the hard drive. The OS should be loaded onto the flash memory, and data stored on the drive. There should be permanent storage sections on the flash memory where programs like Everdream could be installed, for just such occasions. Here is the link.
