In recent months I have got two SGI IRIS Indigo machines: an older one with the 32bit MIPS R3000 CPU and a newer one a much more powerful MIPS R4000 processor (the firs 64bit CPU which was available for the SGI computers).
The boxes are both pretty snappy. Of course, when it comes to raw CPU power, they may be a bit slow. But for most normal applications they are more than OK (I have the IRIX 5.x on both). But even the R3000 one is not slow (it has a 33 MHz CPU). For example, I spent last night in debugging of my program for the GNU Octave and it wasn’t slow. There is a problem with 3D stuff – my machine has no Z-buffer card so many IrisGL and OpenGL programs or refuse to start at all (the FSN, for example) or they have some problems (the Andy Johnson’s Battalion). But a lot of things works well. Actually, I haven’t have too much time to play with it 3D graphics here. I will do it in a future, I hope.
I also did installed the MeshTV visualization software but at the moment I have no software which is able to output it’s SILO data format.
It is quite hard to use such machine for WWW browsing (the Gopher is OK, though). Available programs even cannot connect to most sites (the HTTPS support is too much outdated here). Fortunately, there still are some sites which are optimised for older browsers. So I installed the Netscape 3.0.1 for IRIX and started to use it.
The interesting thing is that the box is very quiet. It’s two SCSI drives are noisy at all which is quite unusual. It’s much quieter than my main workstation (the SGI O2).
The Indigo with the R4000 CPU arrived last week and only today I have managed to set it up. There are some damages from shipping (they broke the frontal doors) but it works. It is interesting that the CPU is a PC model (no secondary cache) which is known to be too slow in modern systems (the Indy and the Indigo2). But this system is fast (at least it feels fast). This machine came with the “Entry” graphics which is really basic: no (Iris|Open)GL hardware, just 8bit colors with dithering and only the 1024×768 resolution (and nothing better or worse). But it has a normal VGA connector which is nice (the 13W3 connector is here, too). So it’s more a general-purpose workstation for 2D tasks than a workstation for 3D modelling.
Actually, I’m thinking about making it my main machine for non-internet and non-3D tasks as it is possible to run here the most of things that I need (the LaTeX, the XFig, teh GNU Octave, Gnuplot and most of my own program codes). But I will see…
A somewhat non-technical post today. We tried to make a light walk near the Slezka Harta water reservoir (north of Moravian-Silesian part of Czech republic, near the Bruntal city). There was a snow storm past days ago and there is still some snow (it’s April 21, so it’s not usual – even for this lower part of the Jeseniky mountains).
We saw lot of animals, mostly deers, does and many birds. But a very few people, fortunately.
We tried to compare our Pebble smart-watches (my wife has a Time Steel one and I have the Pebble 2) – both work well, mine have a heart-rate monitoring functionality which is interesting but they have faulty compass. The Time Steel ones are great and perfectly working (even after more than year of continuous usage.
We also tried to compare our cameras – my favorite (the old but relatively small and AA battery-compatible) HP Photosmart 735 and the Sony DSLR-A200 which is bigger but it should by better in any aspect (and which is preferred by my wife).
So, there is the Velky Roudny vulcano taken by the HP:
And there is the same hill taken by the Sony:
You might remember that around 2007 there was announcet an interesting palm product – a Foleo mobile companion. Essentially a subnotebook with Linux which has designed as an add-n to the Palm Treo smartphones. The Foleo had a comfortable keyboard, a large screen (at least compared to the Treo’s screen) and worked as an extension of the phone. It has it’s own WWW browser (which most probably wasn’t dependent on the phone) and used e-email, calendar and office applications shared with the phone.
The main idea was that user should be able to works with it’s data, e-mails and documents or on the phone or on a larger but still very portable device. Tehere is a lot of places where laptop-style device can be used: in trains, in airports, hotels and so.
Well, the things went wrong as in the same time the netbook hype was started (do you remember the Eee stuff from ASUS? – after all, some of their netbooks were very nice – we still have Eee 901 at home and it still has some use). The netbooks has similar size and battery life but they were much more universal than a very specialised and phone-bound Foleo. Thus the Palm decided to kill the product.
Anyway, some of the machines got to the wild. On can find photos at Flickr or even auctions with never used Foleo.
Well, the Foleo is dead (and the Palm itself is dead, too) and it is irreversible. But is there a modern device with similar idea. Well, two of them: these Chromebooks have somevhat similar idea – they are WWW browser-centered devices. They are less bound to a phone, though.
But there is a something called Superbook which is pretty close – it’s a notebook-style device which is actually an extension of an Androuid phone. I’m a bit curious how it will be succesfull.
It is obvious that the phone has to have a proper case. Even the Ubuntu Touch phone should have one. So I have got one (the Piel Frama Universal Book case for 5″ devices). That’s an expensive one (actually it cost me much more than the phone itself – I’m always late so I have had to get my phone as a second hand item – it was sold out before I decided to get it…).
There is not much to be said about the case – just that it is better to get a 5″ one even if the Aquaris has 4.5″ screen – the 4.5″ case seems to be small for this phone but 5″ case is perfect. The case is of very high quality and protects the phone very well. The “notebook” position is stable enough, too. But it’s something that is expected from the Piel Frama, isn’t it?
The colour is orange – they offer only 3 colours for this case (orange, black and maroon). The black is too boring and the maroon is too strange. So I have got the orange.
It is a less obvious to have the Bluetooth keyboard. It’s useful in situations when a table is available and a long text has to be entered. As I damaged my Stowaway one, now I have to use the Jorno keyboard. It’s expensive when new (once more, I have hot mine as a second hand item) but you can find the some device with a different branding and for lower price (I’m not sure what is copy and what is the original as the history of the Jorno is unclear to me).
It’s small, it’s hinges make no problems during writing (they look more terrible than they actually are) but the keys are smaller than normal and the Esc is only available as Fn+Esc, which is stupid. So writing needs more attention but it is still quite comfortable. The tactile feedback is nice (much better than on the most of mobile and notebook keyboards).
There is one caveat: only the centre of the keyboard is in contact with the desk. The left and the right parts are in the air. So if you have to press mre on the wings (well, the Esc+Fn is this case) then the keyboard may become unstable. Only a small movement is possible but still it is disturbing. So some training is probably needed here.
The biggest issue is, of course, the phone itself – the text can be entered via keyboard (including language-specific characters – the Czech just works!) but many of GUI things cannot be controlled via the keyboard and screen tapping is sometimes necessary. But Unity bar can be accessed easily and te Alt+Tab and the Alt+F4 shortcuts work as expected.
Anyway, it’s hard to say if I’m satisfied with the whole thing or not…
It was not a very active year in the area of geocaching: just few tens of caches. But it includes some T5 caches (well, just relatively easy ones – those available on via ferratas).
The rest were mostly new caches near the Ostrava, Czech Republic. I don’t say that they were not located in interesting places – some of the places were new to me and some were beautiful.
But there was little time for geocaching but also for my all other hobbies, unfortunately. Only a few lines of code were written (and most of them were work-related). The biggest new is that now I have the real SGI IRIS Indigo (even if it’s a rebadget Siemens Nixdorf one) with it’s special keyboard and mouse (but I actually use it with a PS/2 converter). It’s is the early model with the 33 MHz R3000 CPU so it’s limited in OS and software options but it’s nice to play with.
There are no big changes in my mobile stuff. Except the fact that I retired the iPhone 3G – I finally (after 2 years!) managed to cut my second SIMM card to the miniSIM size so now I have both my SIMs in a single phone (the bq Aquaris E4.5 Ubuntu Edition) which.
My wife also found her Sony Clie UX/50 which is a nice clamshell PalmOS device. So we started to use it on a non-regular basis. Possibly, I will try to use it for some development (SmallBASIC runs well here and also the OnboardC works well here – and it’s text editor works perfectly with is’s non-standard screen). But it depends on a free time – at the moment it seems that the things will not improve in a near future…
That’s probably all for the 2016. Happy new year 2017!
There is little new here – except one thing: after many years I have finally managed to make full use of my KVM (keyboard-video-mouse) mechanical switch. It means that I have connected four keyboards and four mouses (I don’t use the video part at all as an acceptable picture is only guaranteed for resolution no higher than 1024×768 and my worst LCD is 1280×1024).
So what is connected:
- SGI O2
- SGI Indy
- Intel Compute Stick (my Linux PC)
- SGI IRIS Indigo
It’s an old mechanical PS/2 + VGA switch so it works in most cases (the Stick requires USB to PS/2 converter).
As you may expect, most time I use the !. and the 3. Other boxes are used sometimes (the Indy is much quieter than the O2 but also much slower and the Indigo I have just because I always wanted to have such thing).
This blog is very silent in last few months. There are two main reasons: I publish mostly on gopher and at work I am too busy.
I do lot of boring office work but sometimes I am able to do something more interesting: some computing, modelling and so. In these cases my desktop looks like on the picture.
I needed to co some computing with use of my FEA package. Of course, I have found several bugs. I also found that some features are already implemented… (I forgot that they exists – fortunately they were describen in the manual). That was funny.
There are some issues: the GUI of software is written in Gtk+ 2.x (and there are fallbacks to Gtk+ 1.2.x and to the basic CLI + GLUT interface). And it’s old and very slow. I wrote most of the GUI before 2006 and I mostly didn’t touched it after that. So portability to Windows or Mac is limited and it is not posssible to run it natively on Ubuntu Touch (nor run it under the Android at all). I though about making of Motif GUI but I never started to code it. And now it probably makes no sense as Motif is even les portable than the Gtk+.
Honestly, the GUI is fully functional in the Ubuntu Touch but only inside the Libertine container (via the XMir) so it looks ugly and it requires external hardware keyboard to be usable. But that’s a small problem. The bigger one is that the only Ubuntu Touch device which I can use for such task is the Aquaris M10 tablet. And it is surprisingly slow when doing this type of computing (but speed in GUI is OK). I’m thinking about Qt5 port but it looks like a long-term problem now.
