For my last blog posting of 2013 I decided on something unusual. Because it was really the year of Google+ for me, I shared out a few of my circles over there in the last few days. This was not an easy decision, because although Google+ is all about circles, I have to admit that I’m not a big circle sharer. This is mainly because my own collection of circles is rather chaotic, but I chose five of my most important circles to share at the end of this year to highlight and thank all the amazing people I’ve met there. I actually shared the circles yesterday directly on Google+ and this is just a blog article collecting those posts together, but this will be the start of a regular feature. But before we come to the circles…

HAPPY NEW YEAR!

Photography Essentials – This one is my “small” Photography circle of people I mainly found in the beginning about one year ago. These are people whose posts I don’t want to miss even when I don’t have time to look at all the other circles. Don’t be angry if you’re not in there – there are two more much bigger photo circles coming up after this!

Photography One – This is the first part of my “big” hand-picked Photographer circles. Everybody from the Essentials circle is also in here, plus everyone I noticed in other circles, who plussed or commented on my posts or who I learned to know through other people. If you’re not in there, either I haven’t noticed you yet or you don’t fulfil my one requirement: you have to post your own work. There are only original photography content creators in here

Photography Two – The second part of my “big” Photographer circle. I had to split it to be able to share it because of the 500 user limit. This second circle is the one I constantly add new people to and maybe I’ll post an updated version once in a while!

Science, Space & Astronomy – One of the other things I try to get involved in, or at least promote, is everything about these three fields and for this reason I have a hand-picked circle with everything about science, spaceflight and exploration and astronomy around. It’s a relatively low-noise group, but everyone from space journalists and scientists from the CosmoQuest / Universe Today crowd, many astronauts and a lot more people are in there. If you want even more, have a look at Fraser Cain’s Super Science Circle, on which my circle is, of course, partly based on.

Astrophotographers – There is some overlap with the Science circle, but I chose use a separate circle for astrophotography to see all the beautiful images in one place. Credit where credit is due, though: this circle is also based, but not completely similar, to one with the same name originally shared by Fraser Cain.

This is just the beginning, let’s see what 2014 will bring…! :-)

Instead of continuing my Commodore story in the Vintage Computing series, I’m going to take a break this week between the holidays and write about some fantastic books and other material, both new and old about the computers of yesterday.

The first entry is a book I found about one year ago through a Slate article – the seemingly cryptic title 10 PRINT CHR$(205.5+RND(1)); : GOTO 10 refers to a tiny BASIC program running on the Commodore 64 that produces an instant maze line by line on the screen, like you can see it in the image on the right (click on it to enlarge). This program is why I love the simplicity of the old Commodore computers – you just can’t do something like this on a modern PC! The book is not strictly about programming, but about programming and computer culture – it takes the one-line program as a basis for a stroll through the computer history of the 1970s and 1980s. Sometimes things get a little too overanalyzed, but on the whole 10 Print… is very fascinating. The PDF is thankfully free to download on the website of the book, but a very pricey printed version is also available.

Another interesting free book is again not solely about programming, but about the games industry of the 1980s is It’s Behind You: The Making Of A Computer Game from Bob Pape. It’s not even Commodore-related, because the author was responsible for the port of R-Type, a popular shoot’em’up console game, for the ZX Spectrum, but for his very interesting and fascinating tale I’ll gladly make an exception even if I know next to nothing about the innards about that other 8-bit machine.

Those are the two newer free books, but if you are looking for more vintage computer books and magazines, I also found some great places on the web. Note that these digital republications are technically copyright violations, but considering their age the downloads at the following links can probably be seen as fair use nowadays.

DLH’s Commodore Archive has literally thousands, maybe even tens of thousands of old books about just every Commodore computer ever built. The collection is awesomly extensive and even contains a vast archive of manuals for all sorts of software and hardware. There is also a fair amount of software in the form of diskimages including a collection of disk- and tape-magazines. The primary language is English, but there are also a few books available in other languages like German.

64’er Online provides a near-complete PDF archive of the German 64’er Magazin with the blessings of the publishers, or more exactly their successors. The original Markt & Technik has long ceased to exist and the name was even eradicated this year when the parent company chose to give up publishing. But this website has almost every issue of the 64’er Magazin from April 1984 to January 1999 – the only drawback is that for legal reasons all the wonderful vintage ads had to be blurred out. But the articles are all intact and are today of great historical value, providing an exciting chronicle of the Commodore 64 and 128 in the 1980s and 1990s. A similar archive can be found here, which also has the Sonderhefte, which are missing on the 64’er-Online website.

The C64 Base is hosted by a pecuilar storage site, but I found the link while searching for old manuals – and this site has them aplenty. There are also tons of books, magazines and advertisements in many languages and even a huge software archive is somewhere inside the directory structure. I’m not entirely sure if this can still be described as completely legal or if it was even meant to be public, but I’m willing to take the risk of linking to it because there is so much amazing history in there. I can’t guarantee that there is not something dubious hidden somewhere in there, but to me it looks like a legitimate endeavour to save historical documents which otherwise would be lost forever.

Music
25. December 2013

I was debating about posting this, but since +Scott Lewis has already shared another version of the song, which is sadly blocked here in Germany, over on Google+, I’ll just do it too with an alternate working link. I think White Wine in the Sun is one of the greatest modern Christmas songs ever written and expresses my feelings about the season perfectly. I know that Tim Minchin can be pretty caustic when it comes to Religion, but this is definitely not one of those songs! This video is a fan-recorded version from the end of Brian Cox’ and Robin Ince’s Uncaged Monkeys live show from 2011 at the Brighton Dome and features Professor Brian Cox at the piano and Tim Minchin on guitar and vocals.

If you’re still here at this point, you can also watch one of my other favourite Christmas songs called Woody Allen Jesus, also from Tim Minchin. This one actually caused a lot of controversy when exactly this performance on the Jonathan Ross Show was cut out at the last minute out of the TV broadcast by the ITV bosses in 2011. Tim Minchin himself uploaded it onto his own Youtube account, this upload is just one with a corrected aspect ratio. There are other performances around, but I think this original is the best and freshest one.

And maybe something more traditional in closing: Pamela Gay in her alter ego persona Pamela Quevillon has recorded a wonderful reading of a less known Charles Dickens story called The Christmas Tree. And with this I wish everyone Happy Holidays again!

I’d like to wish all family, friends, regular readers, commenters and all other visitors Happy Holidays, Merry Christmas, A Happy New Year or any other holiday greetings you prefer! Myself, I like Happy Newtonmas because Isaac Newton was born on December 25th, but I’m very democratic in that respect.

At this time I usually write a longer retrospective article about what’s going on here on the websites, but I think I will skip it this year and just say that the last twelve months may not have been very productive from my angle, but it was still a blast. I’ve written lots of blog posts about a multitude of things here, posted several daily photos over on the Photography Blog and the only thing I didn’t really manage is write more movie and dvd reviews over on DVDLog, but since I’ve been busy everywhere else including Google+, I think that can be excused. Connecting to other people all over the world via social networks has been a lot of fun this year – especially the photographer and science communities on Google+ are amazing to say the least. Oh yes, and I’ve begun to switch my websites completely over from German to English, a process which has still not completely finished.

Instead of taking a complete break between the holidays, I’m only going to put DVDLog into a winter hiatus until February and keep on posting a few photos and collected galleries on the Photo Blog. I will also be sharing some of my Google+ Circles over the holidays which I will afterwards collect here in a blog posting sometime at the end of the week. In a more leisurely and relaxed time, there will also be new and updated version of my hangouts and podcasts recommendations with some special thanks to all the wonderful people who have been tirelessy creating amazing content all year.

So, have a nice and relaxing winter holiday, everyone – I’m going to be semi-around in the next few days and will be taking everything very easy.

After showing the Commodore disk and tape drives I think it’s now time to have a look at the computer itself, the venerable Commodore 64. The one you see in this photo (as usual, click on it to enlarge) is my actual own C64 from March 1989. This is of course the newest and last ever produced version, the C64C or C64-II with an optimized mainboard and the streamlined case modeled after the C128. The first incarnation of the new model came out in 1986 and this slightly modified version with a differently labeled keyboard and a modernized mainboard was sold from 1987 on. At that time the computer was already nearly five years old and had been long technically overshadowed by the Commodore Amiga, which debuted in 1985 – but the C64 proved to be so popular that it was still in production until 1994 when the company itself collapsed.

Science & Astronomy
21. December 2013

There’s so much happening in spaceflight and astronomy at the moment that it’s really hard to keep up, but I just wanted to write a final posting on the subject before the end of the year. The landing of the Chinese Moon probe Chang’e-3 with its Yutu rover, the Jade Rabbit, on December 14th was the most exciting event since Curiosity in 2012. The landing was actually transmitted live by the Chinese state television, but what’s so exciting about a Moon landing – they happen all the time, don’t they? Actually not – this was the first soft landing of a human spacecraft on the Moon since 1976, that’s slightly longer ago than my own lifetime! So seeing the landing play out live was amazing to say the least.

Since the landing it has been a bit difficult to get first-hand information, but Emily Lakdawalla from the Planetary Society has done a great job of gathering the news, images and videos together, like the first colour photoan extensive translation of the recent press briefing and yesterday’s update about the healthy rover and NASA’s LADEE orbiter not noticing the landing at all and a first panorama, still made from low-quality screengrabs. And of course there’s the absolutely awesome landing video, which was put together afterwards from single frames captured by the lander and first appeared on the CNTV website, but was later posted on Universe Today in a corrected version because the original was actually upside down.

Some people are arguing that this is not only the beginning of a new space race, but we’re right in the middle of it with China having painted the Moon red now. But can there really be a race if there is only one participant? China’s Moon mission is not empire building and we are not in the 1960s anymore – of course there’s a fair amount of smugness and bravado on their side, but considering it could also have been NASA taking this step and only politics and finance, but not technical reasons have prevented it, it’s only fair to say that the Chinese deserve all the applause for their successful mission. There’s an interesting article on Space.com about the political background of NASA’s non-cooperation with the Chinese space agency – the ESA has even helped the mission with providing communication links through their network of radar dishes. And I’m sure that there will not be a space war on the moon with lasers shooting down satellites and other science-fiction stuff – there are scientists at work and not power-hungry madmen after all. For all Mankind, as the old saying goes.

As I was thinking about writing this article this afternoon, I was watching two American astronauts performing a spacewalk on the ISS to replace the defective cooling pump that had raised the interest of the media in the last week considerably. Nobody really talks about the space station much anymore and everybody takes it for granted – but if only the slightest thing goes wrong, sensationalism takes over and even allusions to the Gravity movie are made. But is everything so bad, is the space station falling to pieces? Not by a long shot – like every facility, the station just needs some occasional repair work.

The best headline came from Universe today, reading Astronauts get three Spacewalks as an early Christmas present – because that’s what it really is. The spacewalks are extremely strenuous, but every chance to go outside of the spacestation is a treasured adventure for the astronauts. And yes, the water leak problem which hindered Luca Parmitanos spacewalk has been fixed according to NASA, and the only problem more than five hours into the first of three spacewalks seems to be that Rick Mastraccio seems to be understandably groggy and has called it a day after the defective pump was removed. There are two more spacewalks on the 23rd and 25th planned, but everything seems to have gone very well and Rick Mastraccio and Mike Hopkins had actually worked ahead of schedule so that the third spacewalk may not be necessary after all.

And last, but not least… remember that Canadian with the guitar? I can’t believe it’s already so long ago, but Universe Today noted that one year ago Chris Hadfield launched into space. The “launchiversary” was also celebrated by the Canadian Space agency with a wonderful little video, but Hadfield is far away from gone – he may have retired from being an astronaut, but he has written a book about his experiences, is currently on a book tour and continues to be a great spaceflight and astronomy communicator.

Some more random bits: It’s the 45th Anniversary of Apollo 8’s flight around the moon – NASA has re-created the famous earthrise in a wonderful video and space historian Amy Shira Teitel is live-tweeting the events in near real-time. Also, happy Winter Solstice – we are over the hill and the days are finally getting longer and the nights shorter again! Unfortunately we did not get a comet for christmas since ISON seems to have been vaporized by the sun after all, but there’s always the Curiosity Rover available as a Lego set now :-).

Of course, there’s much more going on and I haven’t even mentioned Mars in this posting – but if you follow all the usual channels, you may already be up to date. Usually I don’t bother much with this kind of article anymore, but maybe I will continue to do a monthly roundup of space-themed stories. Soon I will also re-post and update my old podcast and hangout recommendations, maybe even before the holidays.

Last Sunday’s post about the Floppy Drive Mountain was a lot of fun and got an amazing amount of feedback and comments over on Google+, but today I’m going for something much more mundane: the Commodore Datasette. It was the cheap alternative to the floppy drive – using regular audio cassettes for data storage was a pretty good idea going back to the earlier Commodore computers like the PET, which actually had a built-in tape drive in its first incarnation. So it was only logical that the Commodore 64 should also benefit from this simple and inexpensive alternative to the much more expensive disk drive, but it didn’t last long until the floppy drive took over and the cassette drive was almost obsolete in the Commodore world. But many other 8-bit home computers like the Atari 400/800 and the Sinclair ZX Spectrum also relied on cassette data storage, the Amstrad CPC even came equipped with a tape drive in the computer itself.

[Note: also shared on Google+, already lots of comments with amazing memories there!]

When I got my Commodore 64 back in March 1989, I actually got it together with the Datasette pictured above. It’s the 1530 or C2N, one of only two different models produced for the Commodore 64 – it was actually a pretty cheap affair, a somewhat rickety and noisy cassette drive with some basic electronics inside. It was extremely cumbersome to use, the loading and saving of programs took a long, long time, sometimes up to 20 minutes – the speed was actually about 50 bytes per second. It was possible to fit up to 120-130 kilobytes on a 30-minute cassette side, so the storage space was actually quite roomy. The datasette was also very reliable if you used good tapes, but finding your program on a cassette full of saved files could take some time because you had to load through all the files saved before it if you didn’t write down a counter number to spool to.

Together with my C64 and Datasette, I got a few games on tape just to try out the computer, but these were actually quite boring and disappointing. Later I found out that I had accidentially grabbed some from a line of cheap budget releases from a british company called Mastertronic – the best thing with these games, which would load for more than ten or fifteen minutes, were the cassette covers, title graphics and tunes! Some of the games even had a Space Invaders mini-game clone running during the loading process, which was a pretty nifty programming trick, but the games themselves were still rubbish. This was mainly because all the really good Commodore 64 games at that time were not even sold on tape here in Germany anymore and only some cheap stuff was still available.

Because of the limited software available on cassette, the Datasette didn’t last long and I got a proper floppy drive, the famous 1541-II, only about four or five weeks after the computer itself. The Datasette was simply a beginner’s mistake and the floppy drive finally made my Commodore 64 a proper computer. I still held on to the Datasette and I’ve still got it today, but I think it doesn’t work properly anymore – when I pulled it out of its package a few years ago, the motor refused to start. Maybe it just clogged up after not having been used for so long, something which never happened to my floppy drives!

Another six months have come and gone and it’s again time for a new version of WordPress, this time with a complete visual overhaul of the admin interface. I like the slick new design with OpenSans as the new default font and while there are a few isolated things I don’t particularly like, I upgraded my websites anyway. But after each major upgrade, I have to redo a couple of small alterations in the code to make the built-in editor a little more comfortable – even with version 3.8 they are still necessary, so here they are again with some minor amendments.

HTML-Editor: The HTML source editor has been using Consolas as a fixed-width font since version 3.2, but the line height is still a bit to generous especially on smaller screens. The corresponding CSS definition can be found in the file wp-includes/css/editor.css, in which it is possible to change line-height: 150%; in the definition wp-editor-area (formerly textarea.wp-editor-area) to 120% or another desired value.

Visual Editor: The display font of the visual editor is still Times New Roman, but it can be changed in the CSS file wp-includes\js\tinymce\themes\advanced\skins\wp_theme\content.css by altering the font definition in the main .body tag from font-family: Georgia […] to another font like Verdana. There is also now the possibility to let the current theme decide what font is used in the visual editor – this apparently works by placing an editor-style.css file into the CSS directory of a theme, but it seems the only theme that supports it is the new TwentyFourteen coming with this new release of WordPress, which switches the font to OpenSans. I have not yet found out if the font style of the visual editor can be changed directly from the CSS of a theme, but it seems that the new default theme calls up the editor-style.css to make exactly this happen.

Get Shortlink: The shortlink button next to the permalink line sometimes pops into the next line on displays 1024 pixels wide, but the button description can be changed into something less huge. Searching for the string “Get Shortlink” in the file /wp-admin/edit-form-advanced.php and just changing it into something else does the trick. The button can, of course, also be completely removed by deactivating the Jetpack module WP.ME-Shortlinks, but this is of no use if the feature is needed and the button is still too big.

And, of course, it needs to be said that I do not provide any guarantee for these “hacks” – you have to know what you’re doing if you are tinkering around in the innards of the WordPress system files. But if you’re careful and know your way around, these changes will not harm you WordPress installation at all – they are only a cosmetic makeover and no change in the program code is made.

It’s been a while since I wrote something about the new versions of the Opera Browser – mainly because I have been waiting for something positive to come up. The last article I wrote is from July 13 and since then, well… nothing much really happened. The version numbers have increased from 15 to 18 and there are even beta and developer versions with the numbers 19 and 20, but while it’s certainly a fast browser, it still lacks practically all of the features that made the old versions up to 12 so great. The next-generation Opera is essentially still a Chrome clone with even less features than Google’s browser. I’m not only beginning to lose faith on Opera, I’ve actually lost it completely during the last few months.

The biggest problem is that the brower still has no properly functioning bookmark system, even after more than half a year of development. This is the feature that has been requested by many people from the start, but a speed-dial with huge buttons and a “stash” of favourite pages is simply unacceptable as a replacement, especially compared to the well-working bookmarks of Opera 12. There is also no integration of Opera’s own bookmark cloud service Opera Link save for direct web access. That’s really a tragedy, considering where Opera has come from, and it is completely puzzling that the promise of reintroducing “certain features” has not been even remotely fulfilled. The bookmarks bar has actually made a comeback in the latest development version, but real bookmarks are still missing – and may be for a long time, possibly forever.

For this reason, I have actually begun to use Google Chrome as my main browser for some time now – something which I would never have considered before. I started to migrate the most important bookmarks to Chrome and even used the device synchronization feature to keep the bookmarks up to date not only on all PCs and Laptops, but also on my Android tablet, where I also use the mobile version of Chrome now. The main reason for using Chrome on the desktop is, however, its speed: the old Opera 12 is almost incapable of rendering Google+ now and no other browser can display the social network as fast as Chrome. And it’s not only this website, but also, for instance, the WordPress backend, which I use extensively all the time.

The new Android version of Opera actually has exactly the same problem and doesn’t seem to be much in development anymore – apparently a browser without bookmarks is considered as complete on mobile devices and the latest update from December completely wrecked the user interface with spectacularly ugly tabs on the top of the screen. Instead the company has been busy making a browser for iOS devices called Coast, which almost completely lacks an user interface and is only controlled through gestures. This may be an interesting approach, but it only shows that Opera seems to have completely abandoned its core market, the desktop browser.

The bottom line is that Opera as a company has gone from being the most innovative browser developer to almost nothing in less than a year. I don’t give the desktop version of their browser much of a chance now – switching to Chrome or another browser of your choice and keeping Opera 12 as a backup might be the only solution for now.

As a followup to the first photo and article about Floppy Disks, here is an old image from 2003 when I had four different Commodore drives here. Back then I was hunting on Ebay for all the Commodore hardware I was still missing and got some wonderful stuff for very little money. In addition to my original Commodore 64 and its 1541-II floppy drive and the Commodore 128D I bought almost by accident in the mid-1990s, I found two more C64s and a huge set of another C128D and a C128, plus more drives you could shake a stick at. (This posting is also mirrored here on Google+.)

From the bottom to the top, the drives on this image are:

The 1571, which was also built into the C128D. It’s a double-sided 5.25″ drive with two read/write heads that was introduced in 1985 shortly after the C128, but it is also compatible with the C64. It has a built-in power unit, making it much larger and heavier than the 1541-II, although the case looks somewhat similar. The capacity, when used in its double-side mode, was about 340 kilobytes. This particular drive came with the C128D and C128 I bought in 2003. I gave this one away together with the C128 and the 1570 to a friend a long time ago, but got another 1571 later from Ebay.

The 1570 was the predecessor of the 1571 and is actually more shaped like the original 1541 with its frontal latch rather than a handle to lock the disk. This drive was produced before the 1571 was ready to give the C128 a faster drive than the C64, although it only has one read-write head and a capacity of 170 kilobytes like the 1541. It also has an internal power unit, which makes it weigh even more than the 1571 because of its heavier drive mechanics. I got this drive also together with the C128D and C128 in 2003.

The 1541-II was introduced in 1988 after two previous versions of the original 1541, which had a much larger case similar to the 1570. This is the garden-variety single-headed drive which you can use with every Commodore 64 and it is also the most long-living of all 1541s, because it has an external power brick and very robust mechanics. This drive is actually my original one from 1989, which I can recognize from the swapped LED colours of green for power and red for the drive. Despite its robustness, the head motor of this one died sometime in 1994, but I soon got a replacement with my first C128D. Thanks to the several Ebay auctions today I have three other working 1541-IIs, one even in its original packing.

The 1581 made its first appearance in 1986 and was, like the 1571, specially designed to work with the C128 with a special high-speed burst mode, but also worked with the C64. It was the only 3.5″ drive for the 8-bit computers from Commodore and with its giant 800 kilobyte capacity of more than two and a half double-sided 5.25″ disks made it seemed almost like a harddrive. Originally, the drive was much more expensive than its 5.25″ counterparts, but to my surprise I found a 1581 in a local supermarket for a surprisingly low price when I was still using my Commodore 64 in early 1990. The drive became very useful with the graphical operating system GEOS, meaning that I did not have to switch disks at all anymore. I haven’t used it in a long time because it has a broken power switch which I have not been able to properly bypass, but I assume it’s still in good condition. When I used it together with one of my C128Ds to transfer all my disks to the PC, it still worked perfectly.

So this is my mountain of Floppy Drives. I took this photo shortly before I sent the bottom two drives together with the C128 away, so I can’t recreate it today, but save for the 1570 (which is not actually very useful) I still got all these drives here in good working condition.

Bonus picture, but after the fold so the article doesn’t get too long in the main list: some more 5.25″ disks, this time empty ones I bought on Ebay some time back just in case.
