Taper mirror down temporarily

FYI:

My mirror server taper.alienbase.nl is temporarily down.

This server is in fact a virtual machine and the physical host is being moved to another data center. I am not the host server’s owner, it is a donation made by a generous Slackware user that allows me to operate the virtual server using a big bandwidth connection.

Thanks again to the anonymous donor. I know his identity of course, but he wants to remain anonymous. I was not even allowed to mention his company name on the web site…

I’ll bring the mirror server back up as soon as possible, but it will all depend on the logistics of moving the physical hardware and contract negotiations.

LibreOffice 3.5.3

I just uploaded packages (targeting Slackware 13.37 and newer) for the latest maintenance release of LibreOffice. Check out the announcement for 3.5.3: “LibreOffice 3.5.3 provides additional stability to corporate and individual users…”.

If you want to compile this yourself, then remember what I said in my post about the 3.5.2 release: “update … Slackware 13.37 with all the patches which were released by Pat. This includes a spiced-up version of Seamonkey“. All you need to install additionally are packages for Apache Ant and the Archive:Zip Perl module. None of this is necessary if you just want to use my package for LibreOffice.

LibreOffice Math (Formula)

In comments to the LO 3.5.2 blog article, both ngc891 and Willy Sudiarto Raharjo informed me that the LibreOffice Math program did not work in my 3.5.2 packages. If you tried to run “lomath” or “libreoffice–math”, then the Writer would start instead. I looked into this, and found out that several older versions of my LibreOffice packages also did not contain a working LibreOffice Math! I dissected my package and compared it to other distro’s packages. That is how I discovered that my packages were missing one critical file, which (for unknown reasons) is not getting installed by the “make install” routine. Therefore I added a check in the SlackBuild script which copies that “math.xcd” file into the package if it appears to be missing. And now, it works! In the LibreOffice main window, the “Formula” button is no longer greyed-out.

You can find the packages for Slackware 13.37 (and -current) in the usual locations (all of the mirrors below also offer rsync access):

One word of caution!

I wrote this in my previous post as well, but if you did not upgrade from 3.4 yet and this is the first time you are going to upgrade to a 3.5 release, it is important that you follow these instructions first in order to keep your existing configuration, customization and extensions.

Between 3.4.x and 3.5.0, LibreOffice changed the location of its configuration directory (again). Originally using ~/.ooo (a heritage from OpenOffice.org) it switched to ~/.libreoffice which will probably be where you will find your custom settings stored. The 3.5 releases however, use ~/.config/libreoffice . The best thing to do is move your current configuration directory to the new location, so that LibreOffice keeps working as expected:

$ mv ~/.libreoffice ~/.config/libreoffice

If you had already started the new LibreOffice program and noticed that you seem to have lost all your configuration settings, then you will have to stop LibreOffice, delete the fresh and almost empty ~/.config/libreoffice directory and then perform the directory move as shown above.

Cheers, Eric

KDE 4.8.3 packages

The KDE team officially released the sources for KDE Software Compilation 4.8.3 today. I grabbed the tarballs from the packagers site a few days earlier, so that I could again have a full set of Slackware packages for you.

The upgrade will be trivial. Slackware-current was enhanced very recently with KDE 4.8.2 and all the software updates which that move required. Apart from the 4.8.3 release sources, I only had to compile a newer version of libbluedevil and bluedevil, and even those two will be updated in Slackware too, very soon (perhaps Pat already pulled the trigger).

Get my packages here; the official Slackware packages will remain at version 4.8.2, while Pat and the team concentrate on other parts of the distro.

The accompanying README file contains detailed installation/upgrade instructions. Do not fail to follow those instructions!

Have fun! Eric

target_20120501_003

Since last Sunday the weather pretty much threw a spanner in the works in term of shooting (wind-gusts up to 42mph don’t make really for a good pellet shooting experience), I was eager to get out today, despite the weather still being somewhat unstable, I decided to get out and get some rounds through the rifle.

One of the air rifle ranges at Kibworth

When we arrived at Kibworth Shooting Ground, the place was pretty desolate with only a few cars. One of the ranges resembled more of a pool due to the excessive rainfall we’ve been having. After signing myself in at the desk, I made my way to the range (see picture above) which was also quite water logged, with only two other shooters present at the time.

Still it was nice to be out and put the rifle through its paces. I am still getting very much used to firing it. After hitting several targets I decided to set up my targets at 25 yards, while there are some groupings, the results are far and wide and to far spaced out for my liking!

Talking to one of the gents who goes by the name of Mick (heh, there’s about 4 or 5 I believe), he asked if he could put a couple of rounds through with my rifle to see what it was like. This lead to eventually finding out that the recoil pin in the scope had not been extended while the scope was first fitted. So I trotted back to the shop where they were most accommodating to put the scope back.

And back to the range to further fine tune the scope. After a while I think we got it just right. I am rather thankful for Mick’s help. He’s been shooting since he was 12 and he’s quite a bit older than me. There is much I can learn here from the old guard. In the end, I did to hit the spinners out at 45 yards, three times in a row, dead on. I will admit that felt very satisfactory!

Afterwards I went back to a mix of metal field target shooting combined with some shots on my third target set for the day. I am still not entirely happy, or perhaps rather entirely not ;) but I know that it takes practice, patience and dedication and for me, that’s part of the challenge and fun of shooting.

This shows where the learning curve for me is, to shoot consistently and consistently in this case means over all areas. I know I have to focus on stance, breathing and trigger control. I also still have some retained muscle memory with regards to firearms and recoil which makes me pull the gun a bit. This is something I have to unlearn. While my TX-200 HC has a bit of recoil (just enough to make it comfortable recognisable), it is nowhere near as bad as my muscles and brain are trying to compensate for.

This also shows why I dislike the idea of going to a club where the first thought and first thing out of their mouth is “well, we’ll get you set in a team for competition shooting”. As in live, as in shooting; you need to crawl before you can walk and I need to get accustomed to my rifle, put it through its paces and get working on everything before I even will seriously think about participating in a competition.

Still all in all a fun three hours was had. And in the end that is what counts…

I am an avid reader much as Liz, our house if we could would be wall-to-wall, and ceiling high piled of bookcases, as it stands at the moment, two walls around my desk are already taken up by various bookshelves and I know there is at least the plan to add one more bookcase to our collection.

Our range of books are either technical (most of my bookshelves), historical (most of the books in Liz’s office) and just the various genre’s such as science-fiction, fantasy, crime, history (a large part of the Second World War), and a good share of autobiographies). Plenty enough to entertain us if the mood to read strikes us.

One thing, I seem to have inherited from my parents, and their years of mooching around flee markets, book shops and book stalls, is the love of mooching through piles of old books and seeing if there is anything that is worth having a nose through. A while back I found a little indy bookshop tucked away in an arcade in Leicester. I picked up copies of “Never Surrender: Lost Voices of a Generation at War“, and “Task Force Helmand“.  On a subsequent visit, Liz picked me up another three books from there, all on the second world war (One of the periods in history that holds a great fascination for me).

So queue last Thursday as Liz and I went to some shopping and she needed some flowers for the interment service of her grandmother. While I mooched around outside, my eye was drawn invariable to the bookstall there and my eye was caught by several books. On the way back from buying the first three, I saw another that I wanted. So that added the total to seven new books that I still need to read! Much to my delight I seem to have lucky in picking out the three books that form part of Robyn Young‘s Brethern Triology series.

If that isn’t enough, since we both have decent smart phones, (I have an HTC One X, and Liz has a Samsung Galaxy SII) we also used the opportunity to have the kindle for android software on there. Queue more books to read! I have currently started to read through `Ill Wind’ the first book in the weather warden series by Rachel Caine, after seeing it recommended by Felicia Day on her Geek & Sundry Flog.

So, apart from the fact that I am currently reading more or less three books simultaneously (Never Surrender, Ill Wind and Power Play by Anne McCaffery), I am also reading Airgun World Magazine of which I seriously am considering to take out a subscription.

Other than that, there are about 12 books waiting for me to read through. And that is not even counting the other eight books in the Weather Warden series. I almost seriously need a month of Sundays with no internet, and a  good bottle of wine!

So, today both Liz and me retraced our steps to the Kibworth Shooting Ground. After much deliberating, talking and mulling it over since Sunday, I had decided that, yes, I indeed wanted to get myself an air rifle. (Okay not perhaps the huge surprise).

We payed a quick visit to the Leicester and District Small-bore Rifle & Pistol Club. but for some reason it didn’t gave me the same impression Kibworth left on me. In fact it felt slightly off to me. I am not sure what it was, perhaps the over usage of stands, the darkness of the place, or the competitiveness of the shooting that seemed to take place. Competition shooting and how you would be put into a team based on performance was brought up within five minutes of arriving on site. So we decided for Kibworth (plus the fact they have a gunsmith on site, is always a plus).

But after reading and deliberating, I had decided that my previous conversation about which airgun to purchase was skewed by some preconceptions. So I decided to start again and go on the premise that 1) I was new to shooting 2) I didn’t know which gun (a springer, or pre-charged pneumatic aka PCP) would be best for me.

It’s funny though, up till Sunday, I always maintained that I wanted a springer, mostly because it’s harder to shoot, thus a greater challenge. After Sunday, I wasn’t so sure and thought a good PCP airgun may be well worth the investment as well. After talking with both ‘Micks’ at the shooting ground, we all agreed that a springer was better for beginners. Because they are more unforgiving than PCP air rifles you will need to master trigger control and follow through[1]. Thus learning to become a better shooter, something that will undoubtedly be of advantage in any shooting discipline. So I made a full circle from Springer, to PCP, to end up at a Springer

While they didn’t had the air rifle to test fire, one of the gentlemen currently shooting at the air-rifle range had the same rifle with him today and he was kind enough to let me put a couple of rounds on target. The recoil that worried me in the first place, gave an actually very reassuring feel to it, knowing that the rifle had discharged. So soon the choice was made …

And thus, I proudly present, my first airgun, the Air Arms TX-200 Mk III Hunter Carabine.

The Air Arms TX200 Hunter Carbine Mk3 Air Rifle[2] is a fixed barrel, spring powered air rifle, utilizing an under lever cocking action, complete with sliding breech, which shoots the .177 calibre pellets. My current pellets are the Air Arms Diabolo Field .177 cal/8.4 grains (4.5mm / 0.547 grams for those using the metric system).

Since the rifle doesn’t have any iron sights, a decent scope was needed. I eventually settled on a decent Hawke Sports HD scope[3], a “3x9x50” scope for the connoisseur. It makes I think for a decent combination to start shooting. And hopefully eventually (once I can shoot consistently and hitting what I want to hit), perhaps partaking in Field Target, or Hunter Field Targeting.

Other things that I bought today was a beanbag for rifle rest and  shooting support and the nice folks at the shop tossed a gun-bag in it for free to store my rifle in.

Once that was done, me and one of the range officers headed down to one of the sheds that houses the air rifle lanes and he helped me zero in the scope (Thanks Mick!). I was struck by the friendly atmosphere. The other shooters were very welcoming and made me quite at ease despite being an terrible newbie in their midst. The jokes were flying back and forth and I soon realized that it was near impossible to keep a straight aim while laughing. It was all very relaxed and for about an hour or so I aimed, shot and worked the gun (feeling particularly satisfied when I hit a spinner on and about the 45-60 yard range.

All in all, a great great afternoon, very enjoyable. The gun shoots great and although it takes some time getting the pellet into the breach, I am sure that will go easier over time. I felt very relaxed and mellowed out on the way back, and I think a smile a mile wide on my face. I definitely am looking forward to return there, although I need to inquire  about setting up a target so I can see how well my shots group together.

Happy Shooting and stay safe!

Target disks

So, for a while know I have been thinking of picking up a hobby. I have realised that it is way to easy to spend time and time alone and doing stuff on the computer. But lately I have felt the need to get stuff doing outside of the house. But as things go, you might best do something that you really enjoy doing.

Such as; shooting. I have shot during my national service time in the air-force, but with current gun laws[1] in both the Netherlands and the United Kingdom, it’s not something that can be taken up so lightly. That is until I read the blog of a friend of mine who got into air rifle shooting. Suddenly my curiosity and enthusiasm was rekindled.

Last week we visited the Merlin Archery Centre and had a little chat about airguns and such, but the big treat for us (me and liz) was today’s visit to the Kibworth Shooting ground, where we signed up for a taster session. The weather could have been a bit more cooperating but alas, you can’t have everything.

After arriving at the range and welcoming our instructor, Richard, he went over a quick safety briefing about the air rifle, an Air-arms S200, and range conduct and introduced us. Then he started us on the various metal targets, working close range first (about 10 yards) on hitting the kill zone and the revival.

shooting range

Once we had mastered that we got the go-ahead to work up and down the range to the various targets all the way up to 42 yards. I must say I had a great time and got into a reasonable nice rhythm and could have happily go on for much longer. But sadly it was a timed session.

The bloody squirrel

The shot raven

Liz was having trouble getting a particularly rotten target (see the bloody evil squirrel) above, and while I took a break for a bit and trotted back to the clubhouse, the instructor helped her work and zero her scope. And the result was there, the squirrel finally got his deserved hit.

At that time, we came to the last bit of our session, a five shot target shoot (at the normal range distance of 25 yards) and may the best marksman win. I am mildly annoyed that my shots are all far and wide and not nicely grouped. Consistency is obviously something I need to get to work on! So sadly to say, yours truly lost the game with with a score of 26/50 while Liz scored a respectable 35/50. But it was good fun.

5 shot target at 25 yards

Result of the target shooting, shots are far and wide and not grouped...

After that we walked back to the clubhouse with a huge smile on my face and had a quick talk about what type of air rifle would be best suited. They recommended the Air Arms S400 and I must say that after holding it,I found the balance, distribution of weight and length, more pleasant to hold then then the 200 all in all. I must say I was fairly tempted to buy it right there and then. But perhaps so prudence is warranted.

As for Liz, her post on the day can be found on her blog

One thing is sure, I for one had a wonderful time at the range and something I am definitely pursuing as a hobby.

Slackware-current gets KDE 4.8.2, hooray

It was bound to happen, and while I was asleep Pat updated slackware-current with a fresh batch of packages… containing KDE 4.8.2 and all the stuff that it depends on!

The update to the ChangeLog.txt makes up almost 20% of the full ChangeLog length so far! Finally we have a beefy update to -current. It’s playtime for those who had not used my own unofficial “ktown” builds yet.

Note that Slackware’s version of Calligra (the successor to Koffice) is now at the official stable release, version 2.4. My own package was still a release candidate.

Also note that Networkmanager was added to Slackware! So, what I had kept separately in a “testing” directory because I was not sure what Pat would want to do with it, is now being used in the distribution after all. Enabling NetworkManager is done like in my own instructions: make the rc script executable (Slackware will ship NM disabled by default) using the command “chmod +x /etc/rc.d/rc.networkmanager”, and add the NetworkManager plasmoid (widget) to your KDE desktop in order to configure it.

The good old way of using rc.inet1 to configure your network is still available of course, this will not change! Also, you can still use WICD instead if you prefer that. Users of XFCE will want to stick with WICD anyway, since Slackware does not have a graphical configuration tool for managing NM connections, apart from the KDE widget.

Upgrade instructions:

If you are currently running “alien” packages for KDE 4.8.2 and want to upgrade to the official packages in Slackware-current, then you’ll have to be prepared for some manual labour. But it may not be that hard after all, except when you have a lot of my other packages installed as well (like multilib versions of gcc/glibc and lots of “compat32″ packages).

  1. If you are using slackpkg to maintain your Slackware,  then probably you have blacklisted all of my packages.In this case, temporarily remove or comment the line in “/etc/slackpkg/blacklist” that goes “[0-9]+alien”. Then use slackpkg to upgrade to slackware-current as usual, with this condition: do not blindly accept the list of packages to be upgraded, but review every single package shown by slackpkg as a candidate for upgrading. De-select every package which you want to keep! All the “alien” packages related to KDE and its dependencies must stay in a “selected” state. Then let slackpkg do its upgrade work and you’ll end up with a proper slackware-current.
  2. If you want to upgrade using slackpkg but are not prepared to review lots of packages manually to see if they should be upgraded or left alone, then a very fast way of upgrading from my own to Slackware’s packages will be the following four commands followed by a regular upgrade using slackpkg (example paths are for 64-bit Slackware, so if you are running 32-bit Slackware then you have to ignore the “64″):
  1. upgradepkg /path/to/local-mirror-of/slackware64-current/slackware64/a/*.t?z
  2. upgradepkg /path/to/local-mirror-of/slackware64-current/slackware64/l/*.t?z
  3. upgradepkg /path/to/local-mirror-of/slackware64-current/slackware64/kde/*.t?z
  4. upgradepkg /path/to/local-mirror-of/slackware64-current/slackware64/kdei/*.t?z

Note that if you blindly ran these four commands and you are on a multilib system, you will have overwritten the multilib versions of the glibc packages with original (non-multilib) Slackware versions. You will have to download and upgrade to my multilib glibc packages again. Note that this will not break your Slackware installation… it merely disables the use of 32-bit software until you re-install my multilib glibc packages.

Have fun! Eric

Finally, LibreOffice 3.5.2 compiles

A while ago when Libreoffice 3.5.0 was released, I found out to my chagrin that I was unable to successfully compile it on Slackware 13.37.

There was no change when 3.5.1 came out, but thankfully we now have a new maintenance release, LibreOffice 3.5.2. Lo and behold, I could successfully compile packages, but the SlackBuild needed several updates because the build process changes quite dramatically between the various 3.x releases. The developer team is slowly getting rid of the old StarOffice heritage, and ultimately the dependency on Java for the compilation should be completely removed. We’re note yet there however.

What I did manage is to get rid of the requirement to install an xulrunner package in order to create the LibreOffice packages. I updated my virtual machine running Slackware 13.37 with all the patches which were released by Pat. This includes a spiced-up version of Seamonkey which originally got the updates in order to be able to compile OpenJDK, but it is also able to aid in the compilation of LibreOffice. All you need to add now are packages for  Apache Ant and the Archive:Zip Perl module.

You can find the packages for Slackware 13.37 (and -current) in the usual locations (all of the mirrors below also offer rsync access):

One word of caution!

LibreOffice changed the location of its configuration directory (again). Originally using ~/.ooo it switched to ~/.libreoffice which will probably be where you will find your custom settings stored. The 3.5 releases however, use ~/.config/libreoffice . The best thing to do is move your current configuration directory to the new location, so that LibreOffice keeps working as expected:

$ mv ~/.libreoffice ~/.config/libreoffice

If you had already started the new LibreOffice program, then you will have to delete the fresh and almost empty ~/.config/libreoffice directory first of course.

Cheers, Eric
