The build quality seems to be quite high. Its black in colour, but the issue there is that it loves getting fingerprint smudges — so after a while, cosmetically, it looks rather dirty. It comes with an SD/MMC slot, which can be useful with consumer cameras and video cameras, though all the little video cameras I’ve been experimenting with come with a USB slot. It has 3 USB ports. Holding conversations with the built-in speaker and microphone, seem to work well too, so no complaints there. At some stage, maybe I should try recording a podcast “on the go”. The 1024×600 resolution is great — its hard to read and do anything with just 800×480.

Windows First Impressions

I’ve not used Windows on a desktop, since Windows 3.1. Nowadays, at most, I use it in a VM, because I need it for testing. But in these last few days, I’ve been occassionally using Windows, and its been an experience.

First up, I ran Windows Update. Then I installed the following:

• Avast! – this is for anti-virus protection. I used to normally install AVG-Free on Windows machines that I came into contact with, but it seems that Avast! is all that and more. So far, it seems to be getting virus definition files updated almost daily.
• Firefox, and the Flash Plugin – just because
• Evernote
• Google Chroome – not essential, but I’ve always wanted to give it a try, ever since it was announced.
• PuTTY – its crucial for SSH access, which seems to at least give me a semblance of what I’m familiar with
• Dropbox – now my files are synced across my Linux and Mac boxes
• Notepad++ – On Linux, I use vim(1). On the Mac, I use TextMate. And on Windows, it seems like NotePad++ might be what I’m after. Is it? I’m unsure, but so far, I don’t mind it — it has text completion, it can be configured with plugins, I installed aspell so I can run a spell-check (how I wish it would show me an error while I type, as it does in TextMate).
• 7-zip – In the old days, you might think of WinZip. Today, there’s 7-zip, and now I can access my .bz2 or .tar files. Its also opensource software, and I like this, naturally.

You know what I do miss? Keyboard shortcuts. I’m so used to hitting Ctrl+A, Ctrl+E, and Ctrl+K, in the command line, that I can’t seem to get the same responses in Windows. Ick.

What about remapping the Caps Lock key that I never use, to being another Control key? For that, I had to edit the registry! Seriously, what world do we live in?

REGEDIT4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout] "Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,1d,00,3a,00,00,00,00,00

The PowerToys set of tools seem interesting. I installed the Virtual Desktop Manager, which makes Windows more usable – I can now have several workspaces, and move around by pressing the Windows key+1,2,3,4. This is like Spaces.app, and like virtual desktops that you see in GNOME.

I miss Quicksilver. Just hitting Ctrl+Space, and entering the name of an application makes so much sense — does this exist in Windows land?

I have no idea how to perform backups in Windows. What’s the Time Machine or rdiff-backup equivalent?

I find it funny that this little laptop has more disk space than my MacBook Air (which I paid a lot more for). It has a 1.6GHz Atom processor, and its mostly incapable of playing back HD video (stuff that comes out of my Kodak Zi6 for example). But for most purposes (browser, SSH, NotePad++, Evernote) it seems to be fine.

What about the battery life? So far I’ve noticed:

• 5 hours 40 minutes with Skype video running
• 7 hours 50 minutes with just a browser, NotePad++, SSH, Evernote, running

I think I can considerably improve the battery life if I disable Avast!. But should I? I mean, this is Windows, and I am deadly scared of catching a cold.

So there, I’ve been using Windows XP for about two weeks now. It worked wonderfully well while I was at the conference. The laptop is light. I can type on it easily. It seems to do everything I need it to do. I wish there was a real shell (PowerShell, people tell me to try — I will soon), but PuTTY puts me in control of other machines so I just get stuff done.

Would I recommend the Asus 1000HE? Yes, I would. Go forth and buy it!

So, it looks like Asus is rolling out more Eee PC’s, with bigger screens – up to 10 inches. They’ll be loading it with an Intel Atom 1.6GHz processor, and they’re promising 7.5 hours of battery life.

Now we’re talking. The Eee 701 that I own is piss poor with regards to the battery life. And the other thing that has annoyed me for a while with the Eee, is the keyboard. Its just simply too small. I try to touch type with the Eee, and its not that my fingers are fat (really, they’re comparatively thin and long), but its just difficult. The new Eee’s don’t have such an improvement.

They’re still going to be shipping with 12 or 20 gigabyte SSDs. One thing I notice with the Eee is that for critical bits of information, I definitely do not even need more than 4GB of storage.

I think I’m over the Eee. I’ll probably run OpenSolaris on it soon (I wonder if ZFS performs well on flash based storage?) and dock it with a real keyboard, mouse and monitor. And I think that’s where the Eee could shine (or where OpenSolaris could shine) – support a limited set of hardware from a few laptop manufacturers, and one might be a great success if everything “just works”.

What’s caught my fancy this week? The Dell Mini Inspiron. There are photos, and the specifications according to Slashdot (take it with a grain of salt) state:

• Atom 1.6 GHz – just like the newer Eee’s
• 3 USB ports – Apple better start worrying… Seems nicer than the Air, but naturally, OS X simply rocks
• Ethernet
• Card reader – I’ve found reading SD cards really handy
• Mic/line-out
• VGA port, with screen resolution at 1280×800 – winner! It sounds like this might actually be a 12″ screen, which I like

All for under-USD$500? Eee and Macbook Air killer. Of course, no mention of what kind of disk storage will be available. Frankly, I don’t care if its not flash or SSD; throw in an 80GB 4,200rpm 1.8″ drive even. SSD is a solution for a problem that doesn’t exist today for laptops (it offers next to no benefit to hard disks, in battery life or performance).

So Dell, you’ll have my business, plus the extended 3-year “everything” warranty if you come up with something like the above. Make sure the keyboard is usable. Heck, if you can fit 1280×800 on something smaller than a 12″ screen, that’d be fabulous. And don’t forget to throw in WiFi and Bluetooth. Forget an optical drive. Pack it all in with a 7 hour battery life, and you’ll be selling Mini Inspirons like there’s no tomorrow.

Heck, bring back the idea of docking stations! (I realise that a lot of young folk reading might have no idea what a docking station is, but these were fairly popular in the 90’s for laptops, to “enhance” their capabilities with parallel ports, serial ports, an optical drive, etc.) Charge us a whole bunch more for a sensible docking station. The Mini Inspiron might not be someone’s only laptop, but neither is the MacBook Air.

No mention of what OS will be on it. I don’t really care what flavour of Linux comes with it, I’m probably rooting for Ubuntu LTS, but if it comes with something crap like Xandros (aka Eee PC), its easy enough to replace it with something more sensible.

All I can say is that the next couple of months should be real fun for mini-laptop purchasers. It almost seems like you’ll end up owning several mini-laptops, keeping them in various parts of the home… after all, as we all move online, everything we need will be within a web-browser, right? :)

Deciding to spend my credit note immediately at CPL earlier today, I picked up a 2GB stick of 667MHz DDR2 SODIMM, for laptops. Getting home, I popped open the Eee (breaking the warranty void if seal broken sticker), took out the 512MB stick, and replaced it with the 2GB of RAM.

Booted it up, and the Eee is going faster than ever. XFce4 with 2GB RAM is just fabulous. Best $69 that was spent today.

I was looking for RAM sometime last month, even in Kuala Lumpur, and was told that it was all out of stock, so I’m generally thrilled I managed to grab it here, today.

After writing my impressions on Eeedora, it seemed only natural to write about the hardware. There are definitely some issues that I found with the Eee PC that I am not too happy about (and some that are just great).

For starters, who makes a laptop these days, without integrated Bluetooth? It just seems daft. This is a tiny sub-notebook, and how can I get on the Internet if I’m sitting in a train or a bus? The most natural thing would be for me to enable Bluetooth on my mobile phone, and use it as a modem. Oh wait, the Eee PC is missing Bluetooth, and its a WiFi only device. Sure, I can stick a USB Bluetooth dongle on it, but thats an external contraption, that I’ll have to make do with.

I was going through the fine print, and while ASUS provides a 2-year warranty on these laptops, the warranties themselves, seem to be limited to the country of purchase. These warranties, are not international. Who makes a laptop these days, that doesn’t expect the user to travel much? I can imagine that when travelling, the Eee PC can’t be my only laptop – I’m the kind of person that finds Dell’s next-day-onsite-business warranty pretty darn useful.

The keyboard, is tiny, but its expected for such a tiny laptop. I’m wondering why so much space is reserved for the speakers, and why not just give us a larger screen? I have a feeling its got to do with cost, and this can only get better in the future. I’ve noticed that the keyboard requires you to occasionally “jab” it harder, to get the key press that you want. Or its just that my fingers aren’t nimble enough, on this small thing.

The location of the left Shift key, is silly. In VIM, you occasionally tend to press the Up Arrow key, as opposed to the Shift key. I’ve seen people hack their Eee, to ensure that this stupidity is reversed. However, I’m not into moving keys around, to satisfy my needs at this stage.

The one button mouse, that does both right and left clicking is a very nifty feature. How do I middle-click? This is a very crucial feature in Unix land, and especially useful in Firefox (tabbed browsing).

The battery life, for something this tiny, sucks. It sucks even worse, when the WiFi is enabled (quite naturally). My dreams of it being used daily during a conference, or at a meeting, has clearly been shattered. To fix this, I might have to order an external battery pack, that outputs between 9-12V (apparently, 9V is too little to power this 9.5V device, but 12V is just fine).

I’m pretty happy with the performance of the SSD:

[root@Eee ~]# hdparm -tT /dev/sdc

/dev/sdc:

 Timing cached reads:   566 MB in  2.00 seconds = 283.05 MB/sec

 Timing buffered disk reads:    4 MB in  4.39 seconds = 932.40 kB/sec

[root@Eee ~]# hdparm -tT /dev/sda

/dev/sda:

 Timing cached reads:   566 MB in  2.00 seconds = 282.50 MB/sec

 Timing buffered disk reads:   66 MB in  3.07 seconds =  21.50 MB/sec

/dev/sda being the internal SSD, while /dev/sdc being a USB thumb drive (2GB, Sandisk Cruzer Micro).

The built-in video-camera, is pretty standard. Its resolution isn’t great, but it suffices for a video chat.

Sound, is OK. I installed VLC, to allow me to play video/audio, and realised that it was going to set me back, in total, about 21M, with all its dependencies. Hardly appealing, but I was going to have a more interesting time, bringing in Totem, for instance. I have managed to watch a DivX movie, without too much trouble. Will I be able to watch one, entirely, say, while on a plane (or train), I don’t know.

Yes, video, and DivX decoding, works fine on a 630MHz processor. Why has ASUS under-clocked the Eee, giving it a 300MHz performance slack? Did the difference, really save battery life?

There are many ways to hack an Eee. The many guides online, showing how and what one can do (from simple Bluetooth, to a GPS or a touch screen) is just amazing. I don’t plan on hacking my Eee (yet, anyway), and the most I’m going to do, is go get more memory- RAM is always a good thing.

Its small. I spent this week using the train and tram system quite a bit, and realised that even though the trips themselves were short, I was getting some work done (like finding time to write blog entries, and some code – I haven’t gone as far as installing a toolchain on the Eee yet, but if you can find some Internet access later, committing code is easy). Its OK that its cramped. And its OK that it works on top of my huge backpack. These are clear benefits of its size, and hopeful durability.

Its cheap. I had a colleague who’s laptop (a Macbook) died the night before he was about to give a talk. He could head a few blocks down, buy an Eee, and immediately start re-writing his talk again. I saw him deliver his talk, using the Eee and the stock Xandros that was installed on it. In the old day, if your laptop died, you just started to walk around with a notebook and pen,and you gave your talk informally, without slides :)

Anyway, enough rambling (I’m about to reach my stop). Next up, what powertop thinks of the Eeedora install, and re-spinning it.

Being the long-time Linux user that I am, there was no way I was going to be satisfied with Xandros, which is the stock Linux that ASUS ships with the Eee PC. I was stuck for choice between Ubuntu and Fedora, and after some careful evaluation, I decided that Fedora, was right for me.

Getting Eeedora, was pretty straight-forward. The installation wiki is pretty accurate when it comes to the “how” of installing Eeedora. For me, it was made easier that I had a Fedora system already, so I could run the tool to create Live CDs from the livecd-tool package.

One snag I noticed, and this is more with the Live CD script, is that when you don’t have a bootable USB thumb drive, it tells you that, but doesn’t quite tell you it didn’t make an installation on the thumb drive. I guess the script could be more idiot-proof. Anyways, making the drive bootable is easy.

Now, once that was done, it was on to installing on the Eee. I ensured that in the BIOS (accessed via pressing F2), the first boot device was the USB thumb drive attached to the system at boot-up. However, it was never booting into Eeedora, and I only managed to see the Xandros start up. Highly disappointing.

Turns out, that hitting the Esc key was the magic sauce, during boot-up. Only when doing that, was I given a boot menu, and then I could choose if I’d like to boot off the internal SSD, or the USB thumb drive. Once that was sorted, I was pretty happy to see a familiar Fedora-looking screen (sure, it said Eeedora, for legal reasons, but I think its a pretty darn good spin :P).

The installation process went on pretty smoothly. During partitioning, I was pretty much rid of Xandros – the chosen default was actually the most sensible. Just one / partition, filling up the entire disk, with no swap. As usual, anaconda (the Fedora installer) will warn you that not having a swap partition will be detrimental to performance – I wonder how many newbies might decide to create a swap partition (kind of a big no-no, on these SSD based devices).

One thing I did notice was the use of ext2 partitioning as opposed to a journalled filesystem like ext3. The natural question then comes to mind, as to why not just use jffs2?

Once the filesystem partitioning was sorted, and GRUB was chosen as the default bootloader, anaconda proceeded to install packages. This was a fairly speedy process, and once that was complete, it was a simple reboot, and I was booting off the SSD before I knew it.

You’re logged in by default as the eeedora user. You get a stock XFCE4 environment (or stock, that I would think anyway), and it comes with the basic utilities you need to get working (Firefox, wireless, etc.).

There were some things I obviously did not like, so decided to poke a little further. First up, was creating a user, that was not”eeedora”.

Dissecting the .bash_profile of the eeedora user, I noticed some things:

• pulseaudio -D – pulseaudio as a daemon for the user? Why, sound seems to work just fine on my Eee without it
• xsetroot -solid steelblue – seems OK, but not actually required anyway
• startxfce4 – if you want a GUI the moment you login, this is useful. But it only really works out well, because of the hack in /etc/inittab that says c7:12345:respawn:/sbin/mingetty --autologin=eeedora tty7. Seeing that I disabled autologin for the eeedora user, I pretty much see a login screen, and startxfce4 manually. Sometimes, I can actually get away with working in just a shell… However, I can see this from a usability point of view, I guess. Of course, the other issue is that the eeedora user, does not actually have a password!
• Logging out of XFCE4 and going back to the console, immediately triggers a machine shutdown. This seemed counterintuitive.

Needless to say, I disabled all this, in my new user account, as well as disabled autologin in the inittab.

Why XCFE4? Its a 900MHz Mobile Celeron processor, deliberately underclocked to 600MHz, with 512MB of RAM. This is the kind of environment, that can run GNOME. And when we notice problems with GNOME, its time we fixed it. Heck, I have an almost similarly configured IBM laptop, without PAE, that runs GNOME just fine!

I must commend WiFi Radar – this is something that pretty much, just works. And its small. It looks unmaintained, sadly, so its probably time to take an interest in it. Fn+F2 enables and disables wireless very well. I do however notice that even with the wireless disabled, the WiFi light (in blue), remains turned on. I find this to be rather quaint, and must prod it further.

Brightness control (Fn+F3/Fn+F4) seem to work well in Xandros, but I can’t seem to replicate such joy in Fedora. There is absolutely no reason why this shouldn’t work. It does annoy me, because its sucking precious battery life, from my usage of the Eee, by keeping it nice and brightly lit, when I’m on the battery.

Suspend and resume, just work. And because we’re dealing with an SSD, it just works, really fast as well. Sure, when I open up the screen of my Eee, I actually need to press the power button to get it to resume, but this kind of behaviour is perfect for me.

Do I like recompiling all the magic in /root/eee-setup, everytime I get a new kernel? No. Speaking with Dave Jones though, there is an expectation that all the drivers will be available in F9. Kudos.

Webcam? Works fine when I run lucview. Doesn’t work with the Skype beta that I get from the Skype download site. No idea what is missing, I just feel a bit bummed that I’ve got to find the solution to this issue at some stage soon.

As an install report, I think this does, just fine. Its now just time to hack on the distribution, to get it to the way I want it to work.

I’ve been very excited seeing that we announced the Maria Engine Preview. Giuseppe and I were trying to setup a demo, for Maria, at the lightning talks happening later today, towards the end of the MySQL MiniConf at linux.conf.au 2008. It involved MySQL with Maria, and an Asus Eee PC. For the demo, we wanted to show pulling the plug, which can be done either via a kill -9 `pgrep mysqld` or pulling out the battery of the Eee.

However, we failed to get MyISAM to reliably crash! Yes, imagine that, we actually want it to crash – pity that it might have only happened about 1/3rd of the time we tested it. The magic we were looking for:

check table t1;
+---------+-------+----------+---------------------------------------------------------+
| Table   | Op    | Msg_type | Msg_text                                                |
+---------+-------+----------+---------------------------------------------------------+
| test.t1 | check | warning  | 1 client is using or hasn't closed the table properly   |
| test.t1 | check | warning  | Size of datafile is: 23998464       Should be: 16000256 |
| test.t1 | check | error    | Recordlink that points outside datafile at 23000368     |
| test.t1 | check | error    | Corrupt                                                 |
+---------+-------+----------+---------------------------------------------------------+
4 rows in set (0.09 sec)

What we got instead was just a warning mentioning a client is using or hasn’t closed the table properly. Clearly, not so good for a demonstration.

When the magic of set storage_engine=maria; was run, and you crashed (either via pulling out the battery or doing a kill operation), Maria would survive the crash. At worst, you’ll see:

check table t1;
+---------+-------+----------+------------------------------------------------------------+
| Table   | Op    | Msg_type | Msg_text                                                   |
+---------+-------+----------+------------------------------------------------------------+
| test.t1 | check | warning  | Auto-increment value: 0 is smaller than max used value: 32 |
| test.t1 | check | status   | OK                                                         |
+---------+-------+----------+------------------------------------------------------------+
2 rows in set (0.20 sec)

So, Maria is clearly tough, as Giuseppe puts it. Give it a twirl (binaries, sources), and hop on over to the Maria Forums if you have questions. And if you’re checking out/building from source, you might find the Building MySQL from source guide handy

Alas, only a demo in a VM today . It seems more reliable inside a VM, not quite on the Eee. Besides, the poor SSD has been through quite a number of fsck’s now. BTW, one other thing to note: Maria log files seem to be pretty huge. Running it on a SSD that has about 1.5GB of free space (total, 4GB), is harsh.

For reference, the test (generally, wait for count to reach 128, switch terminals, and kill mysqld/pop battery off):

drop table if exists t1;

create table t1 (id int not null auto_increment primary key, b longblob) ;
select table_schema,table_name,engine
     from information_schema.tables
     where table_schema=schema() and table_name='t1';
insert into t1 values (1, repeat('a',1000000));
insert into t1 select null,b from t1; select count(*) from t1;
insert into t1 select null,b from t1; select count(*) from t1;
insert into t1 select null,b from t1; select count(*) from t1;
insert into t1 select null,b from t1; select count(*) from t1;
insert into t1 select null,b from t1; select count(*) from t1;
insert into t1 select null,b from t1; select count(*) from t1;
insert into t1 select null,b from t1; select count(*) from t1;
insert into t1 select null,b from t1; select count(*) from t1;
insert into t1 select null,b from t1; select count(*) from t1;
