I recently put a lot of thought into how I perform my computer backups. I’m one of those people that, while I would only be mildly pissed off by the failure of a hard drive, would be quite angry at myself if I lost even the merest hint of data that I wanted to keep. I used to perform my backups manually, using the Windows backup utility to back data up onto an external hard drive. It worked fine most of the time, but it definitely had process defects… the largest of which being, I had to remember to do it. It required my interaction to succeed (because I had to plug the drive in) and this meant there was always a human element involved. And humans are lazy.

So I set about designing myself the ultimate foolproof backup system. There would be multiple storage media, there would be encryption, there would be checks and validations and several custom-written applications. Then I started thinking, “what exactly am I protecting myself against?” It’s a good question. Here’s the list I came up with:

1. I need my data to be safe from storage media failure. This may mean a single backup DVD being unreadable, or maybe my primary hard disk drives it’s head into the sand.
2. I need my data to be safe from the failure of every drive of a particular type, simultaneously. It happens more than you would think, and the consequences usually aren’t pretty (whole RAID arrays failing, with all their ‘safe’ data, usually makes people a bit upset).
3. I need to make sure my data can’t be stolen. If it is stolen (or people I don’t want reading my data try to do so) then it should appear as meaningless gibberish.
4. I need my data to be safe from being corrupted while in storage, or while being transferred between storage devices.
5. My data needs to be safe from theft or fire, which could mean every storage device in a particular location is unusable.
6. My data needs to be safe from natural disasters, which could take out an entire city or state. Unlikely, but it’s the kind of thing most people don’t plan for.
7. I need to be able to search for data that I’ve accidentally deleted, and I need back.
8. If my data is anywhere not under my direct control, I need to be able to trust the people who do control them.
9. I have to assume that if my backup hasn’t been tested (i.e. I haven’t tried to restore from it) then the backup isn’t any good.
10. Finally, I shouldn’t have to do anything… computers should be smart enough these days to back themselves up.

That was all I could think of, though I’m sure there are additional points (leave a comment or email me, please!). Then I figured out what I had to do in order to prevent these situations from happening.

• Points one and two are the easiest to solve, and are really what most people think of when they think of “backup” plans. The solution is simple: keep your data on multiple storage media, and those different storage media should be different types.
• Point three is pretty simple to solve: encrypt everything you can possibly encrypt. This also partially side-steps point eight, because if your data is encrypted, you don’t have to trust them to not read it, you only have to trust them to not delete it. And you don’t need to trust them to not delete it if you’ve got the data in multiple locations (i.e. somewhere not under their control).
• Point four can be partially solved by taking checksums of the data (which can be done at the same time it is encrypted). If a checksum doesn’t match, something has gone wrong and should be tried again or looked at by a human. There is the issue of what happens if the original data is corrupted. I put this in the too-hard basket for now, though the use of a RAID array can reduce the likelihood of this.
• Points five and six are closely related, and also solved together. Every good backup plan should make use of off-site backups, where a copy of data is kept away from the original. Point five might mean keeping a copy in another building (or in my case, at my parent’s house a few kilometres away). Point six means I might consider going further. Ideally I’d like to store a copy of my data on another continent, just in case of nuclear war. If I survive, my data should too.
• Point seven means I should be creating archives of data, so that copies of old files are kept so that I can go back in time. I would like to be able to choose copies from every day for a week, then every week for a year. After a year, I’m probably not going to remember that I once had a file.
• Points nine and ten are quite possibly the trickiest. To solve them, I have to write automatic scripts to do all these backup tasks, then write automatic scripts to try recovering from the data and make sure it’s in perfect state. I also need to do this manually, just in case my scripts stop working (it is a computer, after all).

So there was my analysis of the backup problem done. Now for the design stage. My current working computer systems consist of a laptop (running Windows 7), a desktop (dual-booting Windows 7 and Debian GNU/Linux), and my home server (which runs Debian GNU/Linux). So I chose to do the following:

• I decided that, since it was turned on all the time, my home server would be the primary location for all my treasured data. Every other location for my data would feed off that. My laptop and my desktop will be synchronised to my server using software such as rsync running on a very frequent schedule. Ideally I will code a switch into the script on my laptop that does syncs less often when I’m not at home, to avoid wasting bandwidth. This will give me three or four working copies of my data, depending on how implementation goes.
• My server has two hard drives, and I’m going to use this to my advantage. The first hard drive has my primary working copy of data, and the second drive is where the backups go. So I’ll write another script that will take my working copies from my first hard drive, perform archival on them (using tar), encrypt them and checksum them (using encryption that money can’t buy) and copy them to my second hard drive. This gives me the ability to go back in time through my data, if need be. At this stage there are some things I won’t backup, either for legal reasons (I’m fairly sure the MP3 backups of my music collection shouldn’t be stored off-site under Australian law) or for practical reasons (videos are just too large to transfer off-site over the Internet).
• I still haven’t solved the problem of off-site backups. To solve this, I’m planning to make use of Amazon S3, which is a cloud backup solution offered by everybody’s favourite friendly forgettable online book store, Amazon. Because my data has now been encrypted, I don’t have to trust them at all. I can just copy it across, mark it as being invisible to the wider world, and forget about it. I will also take up an offer from my friend Jamie to store my data on his NAS, which gives me another off-site backup location. I’m in Tasmania, Jamie is in Queensland, Amazon is in the U.S.A., and my data is safe.
• I’m also planning to fit my server with a DVD burner and write a script that backs up my most crucial data (such as financial information and treasured memories) onto a DVD every week or so. Encrypted, of course. The only problem is that I need to remember to go and change the DVD over every week.
• Finally, I have to write scripts to occasionally check the consistency of my data, so that nothing suffers from bit rot.

I haven’t completed the process of implementation yet (in fact I’ve hardly started). Already though, I feel safer knowing that I’ve thought about the process of storing my data, and that makes me feel a lot safer. Most people don’t think about backups until it’s too late, and perhaps maybe they should.

Over the last few years I’ve been in a similar process, getting rid of my Google account and hosting my own email. I’ve attempted to get rid of Facebook, and learned a lot about myself, my friends, and Facebook in the process. I now no longer have twitter (again) and I’m just generally being a lot more careful with my data.

I think everybody will benefit from thinking just a little more about where their information goes, so I highly recommend you read this article.

Naturally, I prefer to communicate with other humans in person. Every other form of communication leaves something to be desired (and usually, that something is something big).

I’m quite sure that I’m not the only person in the world who has trouble picking up on the subtle cues found in all human communications. The hints of sarcasm (or, in my case, the never-ending stream of it), the smiles, the hand movements, the stances, the tones of voice. A lot of it falls under the umbrella term of body language. Body language is just something the Internet cannot do at all. The telephone, surprisingly, does it even worse (at least in my experience). So I like talking in person the best, because it gives me the best chance to pick up on all these cues.

So, my preferences as far as communications goes:

1. Human contact one on one or in a small group.
2. Human contact in a large group conversation (there’s a large gap between 1 and 2).
3. Instant Messaging (I use MSN and Facebook chat the most). Simply because I can log it.
4. Internet Relay Chat (IRC). If you don’t know what this is, just think chatrooms.
5. Text messages (SMS).
6. And, right down the bottom, in a dusty box underneath the staircase, talking on the telephone.

I think the reason I hate the phone so much is because the person who gets called (usually me) has no choice about when the conversation happens. I could be in the middle of something requiring a lot of concentration (such as programming or web scripting, which requires juggling dozens of variables and logical statements in your head) and the phone rings. Concentration lost.

Of course, if I like you enough, I’ll be happy to shelve whatever I’m doing to talk to you. It’s just that this category isn’t large enough for my boss to be part of it.

One of the most interesting things about WMS, and certainly the thing that caught my eye, was the on-demand pricing they have available, making it very much like cloud computing (as far as the user is concerned, anyway). It’s an interesting concept, and certainly a move that I support (I hardly ever use 100% of my servers’ resources, let alone 100% all month). The only problem is that it makes comparisons with traditional VPS providers who charge a fixed price per month a bit of a pain, and I haven’t quite figured out how to do it exactly.

The other issue I notice is that bandwidth out of New Zealand is very expensive, but this being a function of New Zealand and not Where’s My Server, I don’t think that’s cause for complaint.

Silentflame Web Hosting

During the time I was with Silentflame during 2007-2008, I was very happy. Although the service was a bit slow for me, I suspect that this was purely because I was on the other side of the world. The novel thing about this service is the fact that it gives away all it’s profits to charity. It’s a great idea, and one that I think we should see in more businesses (perhaps a tithe would be better though). No native IPv6 on their services yet, unfortunately.

DirectSpace Networks

I only had a VPS with DirectSpace for about a month or two, before I switched to a different provider. I was fairly happy with these guys, never had any issues that weren’t resolved promptly. The biggest criticism I had with my service was that the CPU allocation was too low. I had severe speed issues from the lack of time my processes had to run. No native IPv6 either.

ServerPronto

I had a dedicated server with ServerPronto for around six months this year, and although I no longer have it, this server performed very well for me over the time I was with them. They do have a somewhat convoluted exit process (it involves filling out a paper form and sending it to them snail mail along with a copy of some ID) but this is no problem to navigate, and unlike what others are saying on the Internet, does not result in your identity being stolen and your credit card being abused. The main selling point of ServerPronto is the price, they are extremely cheap dedicated servers. That said, quality does not appear to be an issue. No unexpected restarts, hardware never failed, and the network is very fast. No native IPv6 here either.

The only reason I got rid of this server was that it was costing more than an equivalent VPS and I wasn’t really using it. I’ve since turned the money over to other VPS services, increasing the number of services I can test.

Nullshells Networks

I’ve used Nullshells Networks’ web hosting for a few years now, and I am extremely happy with the service. All the services I had with them (web and email hosting) have always worked flawlessly, and if I’ve had any queries, the owner of the business has been more than happy to help out. I have only two nitpicks; one is the lack of IPv6, and the other is the fact they use a self-signed SSL certificate. While the lack of signing of an SSL certificate is no technical problem, and while I’m savvy enough to check the certificate and add an exception, it is a bit unprofessional. I’m still using Nullshells for my web and email hosting.

Mammoth VPS

Overall I’ve been very pleased with Mammoth VPS, which is an Australian-owned company with servers located in Sydney’s CBD. While they are more expensive than other offerings, this is simply because the bandwidth in Australia is much more expensive than it is in Europe or the USA, so this is no fault of Mammoth. I have had a few issues with unexpected reboots, but apart from messing with my uptime statistics, this is no real problem. It’s always nice to support local businesses, too. No native IPv6 yet, but almost nowhere does.

BuildYourVPS

I’ve only had a BuildYourVPS (actually TOCICI) VPS for a couple of days now, but I wouldn’t recommend them, based on what I’ve experienced so far. When I first signed up, it took 4 rebuilds of the VPS before I could even log in via SSH. I’m assured this is not a regular thing, but I’d take care. After it was set up, the VPS did work very well. No CPU cloggage issues like on most other VPS providers. The network was extremely fast (as you’d expect from having the servers located in a US west-coast Internet exchange). One thing I did notice is that the server is behind a NAT. Fine, I guess, except that it makes some network configuration tasks a bit more confusing, and that the gateway IP they use is actually a special-use IP reserved for testing. Ouch! Zero marks for that one. On the up side, they do support native IPv6, albeit on request.

Edit 8/10/2010: After playing around a bit more with BuildYourVPS services, I’m happy to report that the issue with server builds has been fixed. All my other complaints were simply OpenVZ issues. Pending a few more weeks with the server, I’d be happy to give them a thumbs-up.

I’m getting really sick of news outlets calling Facebook pages ‘websites’. It’s really demoralising to the people who actually own websites and put effort into maintaining them. I mean, it even costs money! I bet you don’t get the people who create pages spending money on them.

So, Southern Cross News, WIN News, and even ABC News (this one, I admit, surprised me), please just stop confusing pages and websites. If you really want to get pedantic, a Facebook page is indeed a webpage, but it’s not a website. Facebook as a whole is a website.

It also alarms me that the easier it gets to create content on the web, the stupider the content gets (I’m talking about this and this). Which makes me wonder: were the book publishers and the newspaper publishers right? Has the quality of published work suffered because of the Internet? The fact that they might just be right… well, that scares me.

1. The public transport system. It sucks badly. If you want to go anywhere by bus after 6pm or on a weekend, forget it.
2. People complaining about the public transport system. People love complaining about Metro (I’m one of them). It smells. It’s always late. It goes nowhere near where you want to go. All this complaining is really bad; what we need to do is all get on the busses and give them the money they need to fix it. At the moment I can (and regularly do) catch a bus and be the only person on it.
3. Bogans. Individually Bogans are fine. I know quite a few, and they’re lovely people (mostly). It’s just when they get into groups; you start to get the feeling deep inside you that it’s no longer safe and you should leave. It’s not a good thing that The Powers That Be decided to build entire suburbs of public housing, which have now become ghettos.
4. There’s not very much to do. Assuming you don’t drink alcohol (which I don’t), there’s very few things of great excitement in Hobart (if you have ideas, leave comments please!).
5. Rubbish TV stations. People on the mainland get Channel 7, Channel 9 and Channel 10, as well as digital radio. We get Southern Cross, WIN TV, and TDT, which are bad impersonations of the mainland stations. I know Tasmania is a small market, but wouldn’t it be cheaper then to copy the stations over exactly as they are on the mainland and just change the evening news bulletin?
6. Badly surfaced roads. I know this is a complaint pretty much everywhere in the world, but in Hobart’s suburbs it’s getting pretty ridiculous. Neither of the two electorates that Hobart covers (Denison and Franklin) are marginal seats (in fact pretty solidly Labor) so there’s not a lot of money spent pork-barrelling here.
7. Slow Internet. We’re at the end of the world and there’s only a few Internet cables coming into the state. Add to that the high prices charged by ISPs in Australia generally, and it’s a pretty bad situation. The National Broadband Network (NBN) promises to fix the speeds, but at what cost?
8. The jokes about two-headed Tasmanians when you travel to the mainland. It’s getting old guys, seriously.

The USB connector was broken, WiFi only worked half the time, I was starting to get jealous of the iPhone; a number of reasons contributed to the need for a new phone.

I did however love HTC. The phones seemed rock-solid and well designed, especially compared to some of the other manufacturers on the market. Other HTC owners I have met over the years agree; I am yet to hear an HTC owner complain about anything but the price.

I considered a few phones. The Apple iPhone was high on the list, as were a number of Nokia phones, most notably the N79. I will admit at this point to being a brand junkie; there was no way was buying a cheap iPhone clone.

What drew me in to buying the HTC Touch Pro2 was the full QWERTY keyboard and large 3.6″ WVGA screen. I know from owning a decent desktop computer that the most important parts from a productivity point of view are the monitor and the keyboard. They are the parts your body has to interact with, and they should be comfortable.

I bought my phone new in the retail box for $887 AUD from a shop in town. I have seen them as low as $650 on eBay, though I didn’t go this route because I wanted a solid warranty. It is a mobile phone with a hinge, after all.

Now onto the device itself.

It’s far and away the largest and heaviest mobile phone I’ve ever had, or ever seen, or even heard of (apart from the old analogue brick phones). It’s 17mm thick, 116mm long, and 59mm wide. Looking at it another way though, it’s the smallest laptop computer I’ve ever seen. It has a 480×800 pixel screen, as well as a 5-row QWERTY keyboard. Although it is on the small side (naturally) the keyboard is very nice to type with, using both thumbs with the hands wrapped around the back of the device. The screen is also nice, not suffering from glare problems as much as other phones I’ve used (older Nokia phones were particularly bad). If you look closely you can see the individual pixels, but you have to look very closely. It is a very high quality screen.

The screen is a touchscreen, and this is one area where they might have done better. The level of touch required to activate a ‘click’ is in my opinion excessive. It’s far more than on my old phone, or the Apple iPhone. It’s still usable however.

Battery life, as expected for a smart phone with all the bells and whistles, is miserable. I have to charge mine every day, otherwise the battery does run flat. However, being human, I have to sleep sometime, and it’s convenient to charge it every night.

In the box comes a screen protector (very useful, it’s a large otherwise unprotected screen waiting to be scratched), a spare stylus, a USB cable, a wall adapter for charging without a computer, a pair of earphones, and a very nice leather case. The headphones that come with the device serve a dual purpose. The first is as a headset for using the phone, and for listening to music. The second is an antenna for the device’s FM radio. I have to say here that the shape of the headphones is abysmal. They do not fit in my ear at all, and the cable is far too short. If it wasn’t for the fact that they are required for FM radio, I would have just chucked them away.

Inside the device is a Qualcomm MSM7200A chipset running at 528MHz. It’s fast. There’s 512MB of storage onboard, of which around half is available to the user to store settings, documents, and optional applications. Program memory (RAM) is 288MB. More would have been nice, but I’m yet to run out of it.

HTC has gone to great lengths to ensure every piece of software you could desire is on the device, and they’ve managed well, with a few exceptions.

The operating system is Windows Mobile 6.1, upgradeable to Windows Mobile 6.5 some time in the future depending on which carrier you are with. It’s nice, though I notice no huge usability or performance increases compared to Windows Mobile 6.0.

HTC also put their custom TouchFlo 3D software on the device as an alternative user interface. If you’re not used to the Windows Mobile interface, you’ll probably find it nice. I just turned it off and used Windows Mobile as Microsoft designed it. The alternative interface does have a few cool features, mostly related to quickly turning communications on and off as well as turning emails into phone calls near instantly. I get the feeling it’s designed for the jetset business executive. As you may have noticed, I’m not one of them.

The device is also jammed with other software. A YouTube player is there, as is a choice of two browsers (Internet Explorer and Opera Mobile), Google Maps (with support for the GPS built into the device), and Microsoft Office Mobile. As well as a lot more. I loved the fact that Google Maps and YouTube were installed by default, saving me some download time. One application that is missing is Facebook, although given two browsers and a huge screen, it’s not so much of a problem. Opera Mobile even supports tabs, though having more than 2 or 3 tabs open at one time does slow down the device quite a lot, especially when multitasking with other applications as well. I would have liked a few more games installed by default, although I guess I can’t complain – this is a business phone.

Overall, I love this phone, and I’m very glad I bought it. Assuming you have the the money to spare, I would definitely recommend it.

Good:

• Huge 3.6″ screen.
• QWERTY keyboard.
• WiFi, GPS, Bluetooth, HSPA, it’s all there.

Bad:

• Opera slows down when multitasking.
• Battery life is short.
• Included headphones are awful, and using your own requires an adaptor.

Overall: 4.5 stars.

I’m only a light caller (we’re talking a couple of sub-minute calls a week, tops), and only a couple of SMS’ a day. On the other hand, I use a significant amount of data. Every month I use at least 100MiB, and sometimes I go up to a gigabyte. For various personal reasons, I’m expecting to use even more than this over the Australian summer.

So I went through the options, with the goal of paying less (a good thing) or getting more for my money (also a good thing). I currently pay somewhere between $30 and $50 AUD a month.

Telstra - I like Telstra a lot. Signal can be found pretty much everywhere in Australia, and a 3G signal can be found in all the major towns and cities. Call quality is very good also. However, they are very expensive. The Telstra plans I looked at (in particular the Mobile Member Plan) confirmed this, being even worse value for me than my prepaid plan. Data usage (most important for me) is charged at $59 for 1GB, then 25c/MB after that (more info). This is HUGELY expensive. Even with a low-cost $20 plan though, I do get a new phone (but no data).

It’s worth mentioning that I’ve also had a Telstra Prepaid Wireless Broadband dongle in the past. I liked it a lot and found it very functional, but the prices were very high. This is still the case, and the prices are about the same as they were 6 months to a year ago. I’d prefer not to have to have a seperate plan for data, but it is an option.

TPG – TPG have one of the cheapest post-paid plans on the market. It’s $9.99, includes $150 of cap value, with call charges being very reasonable rates. However, at this cheap price, data suffers. Data usage is $5/MB, which is much more expensive than Optus, Virgin, or even Telstra!

TPG’s more expensive plans ($49.99 and $79.99) do include data (500MB and 2GB respectively) as well as free calls to other TPG users in off-peak hours. However, at this price, other providers are cheaper anyway. In addition, none of TPG’s plans include a new phone (although for that price, you can’t blame them).

3 - After a friend’s experience with their accounts department, I’ll never go to them in my life. I haven’t even looked what the prices are, let alone care.

Virgin - Virgin Movile was one of the providers I looked at very closely. For $25 on their Rollover Caps Plus plan, I get more calls and texts than I’ll ever use in a month, as well as 300MB data, which is more than I use in an average month. Also included is a new phone, free voicemail, and free calls and texts to other Virgin Mobile customers (though this is nobody I know, making it a dud offer). It goes straight on the shortlist. If I do use over the 300MB in a month, I can buy a data pack which gives me 1GB (up to a total of 1300MB) for an extra $15 a month. There’s also the Velocity points I earn, but they amount to two parts of nothing.

Also worth consideration is the Beancounter prepaid plan. This has the benefit of really cheap calls and texts to everybody (10c SMS’ to anybody in Australia is very tempting), but falls down in the data department; I have to buy a seperate data pack ($10 for 300MB) seperately.

Optus – The ‘yes’ Cap plans have similar value to Virgin’s post-paid offerings, but without the possible bonus of free calls to other customers of the same telco. With regards to data, Optus is slightly more expensive than Virgin at $19.95 for 1GB. Virgin uses the Optus network (in fact, Virgin is owned fully by Optus, not by the Virgin Group as you would expect) so reception and signal quality should be very similar, at about 96% of the continent’s population at the present date.

Vodafone - Last but not least is Vodafone. They have two series of plans. The first is the SIM Only Contract Caps, starting at $20. This has quite reasonable value at $150, but my research indicates it comes with no data. A data pack can be added, $9.95 for 200MB. This would cover my needs most months, but leave me high and dry in a few.

Their other line of plans is the Contract Caps, starting at $29. These include a new mobile, and for the more expensive plans, some data as well (quite a lot of it, in fact). However, for the cheaper plans it’s the same $9.95 for 200MB as the SIM Only plans.

Another thing to be mentioned about Vodafone is that their network in Tasmania, from experience, sucks. It’s getting better all the time, and in other states is probably quite fine, but is still lagging behind the other networks in Tasmania.

Conclusion

So which one to choose? It’s a hard choice to make. Most of my friends are with Telstra, and would either kill me or not message me anymore if I moved away to another provider. On the other hand, being with Telstra is definitely the most expensive option for me (except for possibly TPG). I won’t go Optus, since I may as well go Virgin. I also won’t go Vodafone, since I like my phone to work around the places I live. 3 is ruled out for being incompetent. That leaves staying with Telstra or moving to TPG or Virgin.

I have no idea what I’ll do yet. I’ll let you know when I decide.

According to Wikipedia, Play School is the longest-running childrens television show in Australia, and more than 80% of young children watch it at least once a week. I’d say that’s been true for the entire running of the series too. Every person I’ve talked to on the matter has watched Play School as a child. Even though they’ve taken the Ning Nang Nong off the regular programming, it does occasionally get a run. And boy does it deserve it.

The Ning Nang Nong has so much pure win in it. It’s hilariously funny, completely insane, horribly addictive, and it impregnates itself in your brain forever. Very few Internet memes can pull as much win. From one comment on YouTube:

GreenCristina: [...] The amount of win it contains cannot even be articulated.

So after a bit of thought, I came to the decision that more Australians would be able to recite more of the Ning Nang Nong than they would of the Australian national anthem (Advance Australia Fair), without listening to either song before hand. I know that I know more Ning Nang Nong, for certain.

So tell me (in the comments), have you seen the Ning Nang Nong? Is it the highlight of your childhood? Can you recite more it than Advance Australia Fair? And is it the biggest pre-Internet win ever?
