Pondering storage options

The combination of curiosity and a little spare time had me browsing online computing technology stores recently. A spot of CD and DVD burning brought on by a flurry of Linux distribution testing reminded me of the possibility. Because I have built up a sizeable library of digital photos, ensuring that I have backups of them is something that needs doing. A 2 GB Samsung external hard drive is brought to life every now and again for that purpose but the prospect of using Blu-Ray discs has appealed to me. After all capacities of 25 GB for single layer discs and 50 GB for dual layer ones sound not inappropriate for my purposes. However, they aren’t a cheap option at the time of writing with each disc costing in the region of £3-4 at one place where I was looking. The cost of BD writers themselves seems not to be so bad though with a few in the £60-100 bracket; any lower than this and you could end up with a combo drive that reads Blu-Ray discs and writes to DVD’s and CD’s so a modicum of concentration is needed. As attractive as the idea might be, the cost of BD media means that I’ll wait a little while before deciding to take the plunge. The price premium at the moment is a reminder of the way that things used to be when CD and DVD writers first came on the market. It is very telling when discs come packaged in jewel cases, something that you won’t see too often with CD’s or DVD’s.

Another piece of storage excitement that hasn’t escaped me is the advent of SSD hard drives. With no moving parts like in conventional hard drives, they bring a speed boost. Concerns about their lifetimes and the numbers of read/write events per drive would stall me when it comes to storing personal data on them but using them for the likes of operating system files sounds attractive, especially with my partiality to Linux perhaps not hammering drives so much. As with any new technology, there is a price premium though a drive big enough for hosting an operating system can be acquired for less than £100. As with many of my hardware purchase brainwaves, there’s no rush but this is an option that I’ll keep at the back of my mind.

Another appealing notion is the idea of getting a NAS so that files can be shared between a few computers. While I have seen prices starting at just above £70 for single disk enclosures, these generally are a more expensive option than external drives and that’s before you consider the cost of any hard drives. Nevertheless, the advantages of a unit containing more than a single hard drive while operating as a print server for any compatible printer too. When you get to 4 or 5 hard drive trays, then the cost has mounted but that could be when they pay their way too. What reminded me of these was a bookazine on home networking that I recently found at a branch of WHSmith’s and their attractions are subject to the networking side of things being made to work without a drama. Once that’s out of the way, then their usefulness really does appeal.

Mulling over all these brainwaves is one thing but it doesn’t mean that the purse strings will become too loose in this age of economic constraint. In fact, pondering them may serve to staunch any impulse purchases. Sometimes, a spot of virtual shopping serves to control things rather than losing the run of oneself.

Extending ASUS Eee PC Battery Life Without Changing From Ubuntu 11.04

It might just be my experience of the things but I do tend to take claims about laptop or netbook battery life with a pinch of salt. After all, I have a Toshiba laptop that only lasts an hour or two away from the mains and that runs Windows 7. For a long time, my ASUS Eee PC netbook was looking like that too but a spot of investigation reveals that there is something that I could do to extend the length of time before the battery ran out of charge. For now, the solution would seem to be installing eee-control and here’s what I needed to do that for Ubuntu 11.04, which has gained a reputation for being a bit of a power hog on netbooks if various tests are to be believed.

Because eee-control is not in the standard Ubuntu repositories, you need to add an extra one for install in the usual way. To make this happen, launch Synaptic and find the Repositories entry on the Settings menu and click on it. If there’s no sign of it , then Software Sources (this was missing on my ASUS) needs to be installed using the following command:

sudo apt-get install software-properties-gtk

Once Software Sources opens up after you entering your password, go to the Other Software tab. The next step is to click on the Add button and enter the following into the APT Line box before clicking on the Add Source button:

ppa:eee-control/eee-control

With that done, all that’s need is to issue the following command before rebooting the machine on completion of the installation:

sudo apt-get install eee-control

When you are logged back in to get your desktop, you’ll notice a new icon in your top with the Eee logo and clicking on this reveals a menu with a number of useful options. Among these is the ability to turn off a number of devices such as the camera, WiFi or card reader. After that there’s the Preferences entry in the Advanced submenu for turning on such things as setting performance to Powersave for battery-powered operation or smart fan control. The notifications issued to you can be controlled too as can be a number of customisable keyboard shortcuts useful for quickly starting a few applications.

So far, I have seen a largely untended machine last around four hours and that’s around double what I have been getting until now. Of course, what really is needed is a test with constant use to see how it gets on. Even if I see lifetimes of around 3 hours, this still will be an improvement. Nevertheless, being of a sceptical nature, I will not scotch the idea of getting a spare battery just yet.

Moving from Ubuntu 10.10 to Linux Mint 10

With a long Easter weekend available to me and with thoughts of forthcoming changes in the world of Ubuntu, I got to wondering about the merits of moving my main home PC to Linux Mint instead. Though there is a rolling variant based on Debian, I went for the more usual one based on Ubuntu that uses GNOME. For the record, Linux Mint isn’t just about the GNOME desktop but you also can have it with Xfce, LXDE and KDE desktops as well. While I have been known to use Lubuntu and like its LXDE implementation, I stuck with the option of which I have most experience.

Once I selected the right disk for the boot loader, the main installation of Mint went smoothly. By default, Ubuntu seems to take care of this but Mint leaves it to you. When you have your operating system files on sdc, installation on the default of sda isn’t going to produce a booting system. Instead, I ended up with GRUB errors and, while I suppose that I could have resolved these, the lazier option of repeating the install with the right boot loader location was the one that I chose. It produced the result that I wanted: a working and loading operating system.

However, there was not something not right about the way that the windows were displayed on the desktop with title bars and window management not working as they should. Creating a new account showed that it was the settings that were carried over from Ubuntu in my home area that were the cause. Again, I opted for a less strenuous option and moved things from the old account to the new one. One outcome of that decisions was that there was a lot of use of the chown command in order to get file and folder permissions set for the new account. In order to make this all happen, the new account needed to be made into an Administrator just like its predecessor; by default, more restrictive desktop accounts are created using the Users and Groups application from the Administration submenu. Once I was happy that the migration was complete, I backed up any remaining files from the old user folder and removed it from the system. Some of the old configuration files were to find a new life with Linux Mint.

In the middle of the above, I also got to customising my desktop to get the feel that is amenable. For example, I do like a panel at the top and another at the bottom. By default, Linux Mint only comes with the latter. The main menu was moved to the top because I have become used to having there and switchers for windows and desktops were added at the bottom. They were only a few from what has turned out not to be a short list of things that I fancied having: clock, bin, clearance of desktop, application launchers, clock, broken application killer, user switcher, off button for PC, run command and notification area. It all was gentle tinkering but still is the sort of thing that you wouldn’t want to have to do over and over again. Let’s hope that is the case for Linux Mint upgrades in the future. That the configuration files for all of these are stored in home area hopefully should make life easier, especially when an in-situ upgrade like that for Ubuntu isn’t recommended by the Mint team.

With the desktop arranged to my liking, the longer job of adding to the collection of software on there while pruning a few unwanted items too was next. Having had Apache, PHP and MySQL on the system before I popped in that Linux Format magazine cover disk for the installation, I wanted to restore them. To get the off-line websites back, I had made copies of the old Apache settings that simply were copied over the defaults in /etc/apache (in fact, I simply overwrote the apache directory in /etc but the effect was the same). MySQL Administrator had been used to take a backup of the old database too. In the interests of spring cleaning, I only migrated a few of the old databases from the old system to the new one. In fact, there was an element of such tidying in my mind when I decided to change Linux distribution in the first place; Ubuntu hadn’t been installed from afresh onto the system for a while anyway and some undesirable messages were appearing at update time though they were far from being critical errors.

The web server reinstatement was only part of the software configuration that I was doing and there was a lot of use of apt-get while this was in progress. A rather diverse selection was added: Emacs, NEdit, ClamAV, Shotwell (just make sure that your permissions are sorted first before getting this to use older settings because anything inaccessible just gets cleared out; F-Spot was never there is the first place in my case but it may differ for you), UFRaw, Chrome, Evolution (never have been a user of Mozilla Thunderbird, the default email client on Mint), Dropbox, FileZilla, MySQL Administrator, MySQL Query Browser, NetBeans, POEdit, Banshee (Rhythmbox is what comes with Mint but I replaced it with this), VirtualBox and GParted. This is quite a list and while I maybe should have engaged the services of dpkg to help automate things, I didn’t on this occasion though Mint seems to have a front end for it that does the same sort of thing. Given that the community favour clean installations, it’s little that something like this is on offer in the suite of tools in the standard installation. This is the type of rigmarole that one would not draw on themselves too often.

With desktop tinkering and software installations complete, it was time to do a little more configuration. In order to get my HP laser printer going, I ran hp-setup to download the (proprietary, RMS will not be happy…) driver for it because it otherwise wouldn’t work for me. Fortune was removed from the terminal sessions because I like them to be without such things. To accomplish this, I edited /etc/bash.bashrc and commented out the /usr/games/fortune line before using apt-get to clear the software from my system. Being able to migrate my old Firefox and Evolution profiles, albeit manually, has become another boon. Without doubt, there are more adjustments that I could be making but I am happy to do these as and when I get to them. So far, I have a more than usable system, even if I engaged in more customisation than many users would go doing.

It probably is useful to finish this by sharing my impressions of Linux Mint. What goes without saying is that some things are done differently and that is to be expected. Distribution upgrades are just one example but there are tools available to make clean installations that little bit easier. To my eyes, the desktop looks very clean and fond display is carried over from Ubuntu, not at all a bad thing. That may sound a small matter but it does appear to me that Fedora and openSUSE could learn a thing or too about how to display fonts on screen on their systems. It is the sort of thing that adds the spot of polish that leaves a much better impression. So far, it hasn’t been any hardship to find my way around and I can make the system fit my wants and needs. That it looks set to stay that way is another bonus. We have a lot of change coming in the Linux world with GNOME 3 on the way and Ubuntu’s decision to use Unity as their main desktop environment. While watching both of these developments mature, it looks as if I’ll be happily using Mint. Change can refresh but a bit of stability is good too.

Changing the earpiece volume on a Nokia 1661

The Nokia 1661 is an entry-level phone so you’d have thought that they’d have made it obvious how to change the earpiece volume on the thing. However, it turns out to be something for which you do need to consult its manual and it’s not as user-friendly as it could be either. Seemingly, the earpiece volume only can be adjusted while you’re already on a phone call and you need to use the scroll key (push in left and right sides as needed) that could be right up against your face at the time! My way around this is to phone the speaking clock (123 in the U.K.) and adjust the earpiece while that call is in progress. Then, you’re set for future conversations with real people. Well, anything’s better than not being able to hear the other person due to background and my Nokia 1661 came with its volume set rather low on me, if I remember correctly. While I can appreciate the need to look after your hearing, you do need to have coherent phone conversations too.

Why go elsewhere when you can get it at Argos?

It is perhaps a sign of the technological times in which we live that even mainstream stores like Argos stock computing equipment these days. For instance, last weekend, I bought a Seagate Expansion 2 GB external hard drive in there for backing up my digital photo collection and never got to a local independent computer shop like I had planned to do. Maybe, it was the convenience and lack of fuss with a catalogue shop that swung it for me but the largest size at the other place was 1 GB according to its website anyway.

Other items bought from the pervasive chain have included a BlackBerry, a Vodafone mobile broadband dongle and an Asus Eee PC. All have done what I have asked of them and without any trouble but it does make me wonder about the threat to the specialist PC stores from their more mainstream competitors and it isn’t just Argos either. Tesco also tempt folk into their stores with technological goods and I must own up to having a cheap DVD player from  there.

In former times, I might have been lured into purchasing at online stores until the reality of dealing with inflexible delivery services took away the shine after a few years. After all, I’d prefer not to burden neighbours with taking delivery of any purchases. My current job offers the possibility of some home working so that might be an option for those things that do need delivering but there remains a certain immediacy to going into a real shop for what you need and bringing it away on the day (having paid for it, of course) that is difficult to beat.

While I tend to decide what to get using my mind after doing some research, others may prefer the idea of getting some advice in a shop and that’s where the specialists score. In fact, it may be the only way that they are going to cope with the onslaught from megastores like Argos and Tesco. All this reminds me that going to a local independent shop next time is in order because they cannot be doing brilliantly in these cash-straightened times.

An Eee PC

Having had an Asus Eee PC 1001 HA for a few weeks now, I thought that it might be opportune to share a few words about the thing on here. The first thing that struck me when I got it was the size of the box in which it came. Being accustomed to things coming in large boxes meant the relatively diminutive size of the package was hard not to notice. Within that small box was the netbook itself along with the requisite power cable and not much else apart from warranty and quickstart guides; so that’s how they kept things small.

Though I was well aware of the size of a netbook from previous bouts of window shopping, the small size of something with a 10″ screen hadn’t embedded itself into my consciousness. In spite of that, it came with more items that reflect desktop computing than might be expected. First, there’s a 160 GB hard disk and 1 GB of memory, neither of which is disgraceful and the memory module sits behind a panel opened by loosening a screw so I am left wondering about adding more. Sockets for network and VGA cables are included along with three USB ports and sockets for a set of headphones and  for a microphone. Portability starts to come to the fore with the inclusion of an Intel Atom CPU and a socket for an SD card. Unusual inclusions come in the form of an onboard webcam and microphone, both of which I plan on leaving off for sake of privacy. Wi-Fi is another networking option so you’re not short of features. The keyboard is not too compromised either and the mouse trackpad is the sort of thing that you’d find on full size laptops. With the latter, you can use gestures too so I need to learn what ones are available.

The operating system that comes with the machine is Windows XP and there are some extras bundled too. These include a trial of Trend Micro as an initial security software option as well as Microsoft Works and a trial of Microsoft Office 2007. Then, there are some Asus utilities too though they are not so useful to me. All in all, none of these burden the processing power too much and IE8 comes installed too. Being a tinkerer, I have put some of the sorts of things that I’d have on a full size PC on there. Examples include Mozilla Firefox, Google Chrome, Adobe Reader and Adobe Digital Editions. Pushing the boat out further, I used Wubi to get Ubuntu 10.04 on there in the same way as I have done with my 15″ Toshiba laptop. So far, nothing seems to overwhelm the available processing power though I am left wondering about battery life.

The mention of battery life brings me to mulling over how well the machine operates. So far, I am finding that the battery lasts around three hours, much longer than on my Toshiba but nothing startling either. Nevertheless, it does preserve things by going into sleep mode when you leave it unattended for long enough. Still, I’d be inclined to find a socket if I was undertaking a long train journey.

According to the specifications, it is suppose to weight around 1.4 kg and that seems not to be a weight that has been a burden to carry so far and the smaller size makes it easy  to pop into any bag. It also seems sufficiently robust to allow its carrying by bicycle though I wouldn’t be inclined to carry it over too many rough roads. In fact, the manufacturer advises against carrying it anywhere (by bike or otherwise) with switching it off first but that’s a common sense precaution.

Start-up times are respectable though you feel the time going by when you’re on a bus for a forty minute journey and shutdown needs some time set aside near the end. Screen resolution can be increased to 1024×600 and the shallowness can be noticed, reminding you that you are using a portable machine. Because of that, there have been times when I hit the F11 key to get a full screen web browser session. Coupled with the Vodafone mobile broadband dongle that I have, it has done some useful things for me while on the move so long as there is sufficient signal strength (seeing the type of connection change between 3G, EDGE and GPRS is instructive). All in all, it’s not a chore to use so  long as Internet connections aren’t temperamental.
