Today was one of those days where a dusting to 1" turned into a bit more snow for Boone. All of these photos were taken through out the day with the Fuji x100s.
Ran into some folks out and about doing or wearing interesting things. This dog was pretty excited to get a move on.
Winter clothing can sometimes be interesting.
As far as I could tell this is like that thing where people stack stuff on their cat but with a person.
Like getting random stuff in the mail? This year I'm going to mail out some prints to people who want them. They'll be either 4" x 6" or 5" x 7" depending on the paper I have laying around at the time. The image will be mostly random, could be pertinent to how we know each other or just whatever the heck I feel like printing. All of them will be photos I have taken.
If you want to participate please send the address of your mail hole or receptacle to firstname.lastname@example.org.
In person delivery is an option if you are with in my laziness radius.
I've been taking a Japanese class over the last semester so I've had a need for Japanese input on laptops. I've been running Fedora KDE on my portable machines lately and I had no trouble finding documentation on changing up input methods on Fedora GNOME but there was little out there on the KDE spin. Some of the Kubuntu documentation got me in the right direction though.
The method I found for kata and kanji input uses fcitx, which have packages in the Fedora repos:
sudo dnf install fcitx-kkc kcm-fcitx
After those have installed add the Fcitx utility to the Autostart items in Plasma 5. Also, add the fcitx input modifiers in /etc/profile.d/fcitx.sh:
export XMODIFIERS="@im-fcitx" export QT_IM_MODULE=fcitx export GTK_IM_MODULE=fcitx
Restart the machine and open up the Fcitx Input Method configuration, you'll want to add the Japanese Kana Kanji as a secondary input method. If you don't see it come up in a search uncheck the "Only Show Current Language" option.
Now you should be able to hit Crtl+Space in any text input field and replace Romanji with Kana or Kanji characters. Additional presses of the space bar will cylce through different characters for the same sound. So you can have にほんご or 日本語 for example. Pressing Crtl + Space exists the Kana Kanji input mode. Pressing return after a typing a word in kana or kanji finishes the slection and allows you to move on to the next word. Very useful and no swapping keyboard layouts!
Just a few photos from the last couple of month around Boone, NC. All taken with either the x100s or X-T2.
This was originally posted some time ago on Deskthority. Hosting it here for posterity's sake.
Recently I stumbled on a 1393464 Model M off eBay for a decent price. This was a model with custom keycaps made for the American Airlines reservation system. Otherwise it's a normal 2nd generation Model M from 1990. I just think the differently printed keycaps look neat.
It arrived and I found that some of the keys were non-functional and I tracked it back to a dead line in the membrane. Since I'd never fully deconstructed a Model M before I decided to give it a go. Usually I just do the screw mod when the rivets break. Ordered the $10 membrane from Unicomp and it arrived Saturday. Just tonight I go the board all the way back together and it works! Typing this post on it right now. Below are some photos are comments on the process. It was more challenging than I thought it would be, getting the springs and flappers to stay in place while you re-attach the membrane and back plate is kind of tricky ...
Model information, this particular unit was built on Feb 06 1990
Beige/cream barrel plate, this is a new one to me. I've only ever seen black ones ...
Just a quick note on the new membranes from Unicomp: if you have an older M you're resotoring you'll need to trim off the rightmost four lines from the smaller ribbon cable. These membranes work with the older Ms but have the built-in lines for the LEDs on the new models. I just used a razor blade and some patience.
New membrane pre-install...
Keycaps back in and ready to be tested!
All back together and ready to go. All in all not too bad of an experience and I found some threads on here helpful. Just thought I'd share the journey. Not sure how rare or special this particular Model M as it just showed up in my running eBay search. Found some info on the Clicky Keyboards site but that's about it. I think the membrane went bad due to some liquid exposure as it looks like there was some dried liquid in between the sheets. Anyway, should be good for another 28 years now I reckon.
Just a couple of shots from last week's snow storm.
Fujifilm X100s processed in Darktable. First real snow of the 2017-2018 winter at a few inches here in downtown Boone, NC.
If you’re into amateur radio you’ve probably heard of these cheap DVB-T tuner dongles re-purposed as software defined radios. They’re very popular for building scanners and streaming setups. I’ve got a couple of models that I use with Gqrx for listening to traffic on the local repeaters, weather radio and a few other things.
This weekend I finally had enough time to sit down and setup rtl_fm and try out a streaming solution for listening to NOAA weather broadcasts. I’ve streamed scanner and weather radio traffic using Icecast before but that was with a external radios and a mic input. This time I wanted to use a machine with no sound card (my home server machine). All of this was done on Debian Linux 8, to get started we need three pieces of software:
rtl-sdr ezstream icecast2
All are available in the default repositories so just install them with apt.
Next I had to configure icecast2, the most basic configuration should work but at least change your admin and source password in the authentication block:
<authentication> <!-- Sources log in with username 'source' --> <source-password>password123</source-password> <!-- Relays log in username 'relay' --> <relay-password>password123</relay-password> <!-- Admin logs in with the username given below --> <admin-user>admin</admin-user> <admin-password>password123</admin-password> </authentication>
That should at least allow you to connect and get up and going. There are other options to secure and/or tweak but I’m not going to cover those here.
I used my NooElec Nano SDR as a test source. The rtl-sdr package comes with a program to handle FM tuning called rtl_fm. There are a few options to tinker with here but only too options are critical for operation here:
rtl_fm -f 162.500m -M fm -
-f 162.500m: sets the tuner frequency to 162.500Mhz -M fm: tells the tuner to use standard narrow FM tuning, if you want to listen to commercial radio you’d use wbfm or wideband FM. -: directs output to stdin
Send that output to lame to encoding:
lame -r -s 24 -m m -b 64 --cbr - -
-r: assume raw pcm input -s 24: set the sample rate to 24K -m m: mono mode, NOAA doesn’t broadcast in stereo -b 64: set bitrate to 64kbps, it’s more than enough for this --cbr: constant bitrate - -: stdin/stdout
A quick note here, you’re going to have to mess with the sample rate in LAME to get things sounding right most likely. I arrived at 24K, much higher or lower and the pitch is off. It may not work with your model SDR, etc.
Lastly ezstream needs configuring. It took a while to get a working MP3 configuration sorted out but I eventually arrived here:
<ezstream> <url>http://localhost:8000/WNG588</url> <sourcepassword>password123</sourcepassword> <format>MP3</format> <filename>stdin</filename> <!-- Important: For streaming from standard input, the default for continuous streaming is bad. Set <stream_once /> to 1 here to prevent ezstream from spinning endlessly when the input stream stops: --> <stream_once>1</stream_once> <!-- The following settings are used to describe your stream to the server. It's up to you to make sure that the bitrate/quality/samplerate/channels information matches up with your input stream files. --> <svrinfoname>WNG from Mt Jefferson, NC</svrinfoname> <svrinfourl>https://hubble.buttonhost.net</svrinfourl> <svrinfogenre>Public Information</svrinfogenre> <svrinfodescription>NOAA Weather Radio from Mt Jefferson NC</svrinfodescription> <svrinfobitrate>64</svrinfobitrate> <svrinfochannels>1</svrinfochannels> <svrinfosamplerate>44100</svrinfosamplerate> <!-- Allow the server to advertise the stream on a public YP directory: --> <svrinfopublic>0</svrinfopublic> </ezstream>
Save this to /etc/ezstream using your favorite text editor and pass it to eztream thusly:
ezstream -c /etc/ezstream.xml
The whole thing piped together looks like this:
rtl_fm -f 162.500m -M fm - | lame -r -s 24 -m m -b 64 --cbr - - | ezstream -c /etc/ezstream.xml
I just stuck that whole string into a shell script. If you want it to start at boot time you can shove it into /etc/rc.local for a quick and dirty solution.
Once all that is done it’s a simple matter of navigating to your Icecast server at http://whatever_url_u_have.com:8000 and clicking the m3u icon by the stream listed there. Open that file in whatever music player you want and enjoy. I use VLC, Rhythmbox or iTunes (when I find myself on a Mac) myself. Otherwise you can just check the weather app on your phone like a normal person. Next up I want to work on getting frequency scanning working so I can get the scanner back online.
Oh and you can check out the fruits of my work here: http://hubble.buttonhost.net:8000/WNG588.m3u
Windows 10 is pushy and aggravating. So glad I only really have it in a VM for a couple of things. Thanks multi-core CPUs and VirtualBox!
"Would you like to make Firefox your default browser?"
-> Clicks yes
-> Doesn't actually make Firefox your default browser, but sends you to a control panel to do so.
Me: "OK, I'll just change it here" Clicks button to change it to Firefox
Windows 10 pops up an alert: "Whoa, wait a a minute there partner. Did you know Edge is the best thing since sliced bread? What sort of intellectual deficiencies do you have that makes you want to use something else? Are you sure that you really want to do this? I hear Hitler used Firefox."
Me: "Wut, OK this is getting silly. Just do it already!"
That took about five more steps than it should have. Linux and OS X (errr macOS) have their moments and problems but I don't know why Windows users put up with stuff like this. That last alert was obviously exaggerated for humor but it did indeed plead with me not to change away from Edge.
Position of HD 164595 in the constellation Hercules
With apologies to Dr Stephen Hawking for the title.
The media is running amuck with stories of an ET signal from HD 164595. It's an intriguing concept as HD 164595 is rather close to our sun on the main sequence with at least one known planet. However this outburst is unlikely to be from another civilization for a number of reasons.
First, let's look at few more promising ET candidates that turned out to be more regular natural phenomena. The most famous is probably Percival Lowell's martian canals. In the early 20th century photography was still in it's infancy so many astronomers still did visual observing. This combined with the human ability to insert patterns where none exists led Lowell to publish his findings as a civilization building canals. Not to fault him entirely as Mars does actually have a dynamic and constantly moving landscape but it's due to seasonal dust storms, not martians irrigating their crops.
The next promising candidate was the discovery of pulsars in the 60s. The first pulsar was found to pulse at 1.33 second intervals in the radio part of the spectrum. Antony Hewish and Jocelyn Burnell ruled out human made interference and jokingly named the radio source LGM-1 for "little green men." They didn't actually think the radio signal was from some far off alien intelligence, the name was just a joke. However popular media at the time certainly ran with that idea. Later, after more of these regular pulsing radio sources were discovered it was surmised they were rapidly rotating neutron stars. You know, just the corpses of long dead massive stars. Nothing terribly exciting there at all. Sarcasm heavily implied here in case you didn't pick up on that.
One of the more recent "it might be aliens" discoveries were so called perytons. They were only detected by the radio telescope at Parkes and only there since 1998. All sorts of theories were tested and after other radio telescoped failed to detect the signal and astronomical sources were excluded the team started to focus in on local phenomena. It turned out to be the observatory's microwave oven, I kid you not.
So with the colorful history of discoveries that might have been ET let's look at the HD 164595 signal. It's a strong microwave spike. So strong infact some have theorized that it could only be produced by a civilization that could harness the entire output of their parent star. It's rather unlikely that something capable of such engineering would still be using microwave transmission for communication. The signal also also isn't spectrally narrow like one would suspect an intentional transmission to be. There's also the fact that it doesn't particularly look like something you'd expect intelligent beings to be sending out. No obvious patterns. The argument could be made for it to be encrypted or encoded but if you're trying to get a neighboring star system's attention you probably want them to be able to understand it. Sure, it could have not been intended for intercept but why else would ET's be blasting out huge microwave bursts? An alien intelligence might use some mathematically significant signal or something else obviously artificially generated as a beacon to stand out against the noise. Random spectrally wide microwave bursts don't really do that. In fact, I'd say pulsars would have been a better candidate for SETI than this signal back in the day as their signals seemed to tick more boxes on the "might be ET" checklist. Sure, HD 164595 could be another intelligent life form trying to communicate with us but that requires extraordinary evidence. The signal could just as easily be Carl microwaving his burrito again.
The suspect signal from the paper
Simplest explanation is that it's some natural phenomena we don't fully understand. We have observed exactly one star up close and personally and have in depth experience with one solar system. There is a lot we don't quite understand yet. This isn't some smoking gun for aliens as the media is screaming about. It certainly warrants further study though.
Gear doesn't matter, until it does.
I've been slow to move to a mirrorless system. Part of the reason is my current DSLRs work more than well enough for my needs, part was lack of system maturity in the mirrorless world and the last part was lack of resources to go throwing a bunch of cash at a new system. Personally I'm still unsure if a mirrorless system can completely replace my DSLR at the moment. I do a lot of astrophotography and the lens selection combined with the high ISO performance in the Nikon world is critical. I haven't seen anything that comes close to some of the fast wide glass Nikon makes yet. Sony is getting there but they've been shooting out a new A7 body every six minutes it seems. I guess you could call that "spray and pray." While their cameras are technical marvels the few I've laid hands on were a bit clunky to use. I also don't see the size and weight benefit on full-frame mirrorless system over a DSLR. I'm certainly not knocking the image quality that Sony has achieved that's for sure. But I don't see the benefit of dumping a Nikon system I'm already invested in, taking a bath on the gear, sinking about $4,000+ into bodies and lenses for what amounts to a marginal weight savings and lost access to Nikon's accessories and service. This is doubly true when you compare the A7's images to Fuji's or even Sony's own A6000 series. Outside of the need for extremely high res files I don't see a compelling reason to drop the coin an a full-frame mirrorless in general unless you don't already have a full frame DSLR. Crop cameras make a more compelling argument to me in the mirrorless form factor. You can get actual weight and space savings and killer image quality. Again Sony's own A6000 series illustrates that. As an aside I haven't tested an A6300 but it has certainly piqued my interest.
Fuji is the other major player in the mirrorless world. They have the hipster look down with their retro styling, which I wasn't a fan of at first (more on that later) and not as varied of a lens library as Sony right now too. Thus enters the X100s. "Wait," you might say "isn't the X100t the new hotness, why are you writing about last year's model, senility finally kick in?" Well, remember that last reason why I haven't jumped in to a mirrorless system? Turns out life is expensive and photography has been on the back burner for a while. I haven't really earning income from photography over the last couple of years either so my gear isn't paying for itself. That being said I think on the whole I think digital cameras have been more than good enough since 2009 or so. There aren't a lot of reasons to upgrade with every generation of camera like ten or fifteen years ago. I still use a D7000 as one of my secondary bodies and it's never held me back. Picking up an older model can save some cash and still net you outstanding images.
So, what was I going on about? Oh yeah the X100s. I'm not going to bother you with the technical details of the camera too much. 16MP, 24mm (~35mm on FX) f/2 lens, some video modes, film presets, yadda yadda. More detailed specs can be found all over the web. I'm not sure what I was expecting but I will say I've underestimated on a quite a few points this camera. First of all was the styling. I like functional designs which the X100 series has covered but the retro look rubbed me the wrong way. In a lot of the same ways that the PT Cruiser the HHR make me roll my eyes. But after a few days using the camera in public I saw the clear advantage of having a camera that didn't look big nor digital.
Usually I spend about thirty to forty five minutes on a walk around town a few times a week. I get free exercise and it's been an opportunity to use my cameras. I've done this in the past but even with just a 50mm prime on the D800 I had issues with people getting nervous, giving me dirty looks and generally not being friendly. Because what in the world could you be photographing in downtown besides women and children for nefarious purposes? Seriously there are people in about one out of ten of the shots I take on the street. You folks aren't that interesting, chill out. To be fair I probably look the part (kinda fat, white, bald, male) of your stereotypical weirdo. Mix in an awkward personality and you've a recipe for getting to know your local security personnel or police. It only made my anxiety worse. For the last few years I've tried to just work around it but ultimately just quit taking the camera with me. However, once I took the Fuji out things changed almost instantly. I was no longer that weirdo with that big Pervtron 800 trying to take creepshots but that cool guy with the old camera. Ok, I've never been cool in my life so maybe that's a stretch but people actually asked me about the camera and were interested in my work. It was really kind of strange out at first. But now I enjoy my little photowalks again. So, if you do any sort of travel, street or general in public type photography the retro styling serves a purpose.
Very clever Fuji, very clever indeed.
Which brings me to the handling. Usually me and small cameras don't mix. I have sort of large hands and even small consumer DSLRs give me grief. I was expecting the X100s to be a bit more cramped and harder to operate and easier to drop. Again, I was pleasantly surprised. It's well balanced and is remarkably easy to use by feel. I'm still getting used to the whole rangefinder thing but even that's not as steep of a learning curve as I was expecting. The aperture ring and metal dials are comfortable enough, although the rubberized dials on my Nikons are a bit easier on the fingers. A few more programmable function keys would also be nice. I set the Fn to control the built in ND filter but I'd like another for ISO instead of having to duck out to the Q menu. Really that's more of a nitpick though.
On a kind-of-sort-of related note, if you're like me and do any sort of outdoor portraiture in broad daylight the X100s is going to become your new best fried. It's about the cheapest thing on the market with a leaf shutter which means it can sync with a flash to its max shutter speed at a given aperture. I've been using it with some cheap YN560s and a Youngnuo remote. f/2 at 1/1000" is awfully nice, f/2.8 and 1/2000"? Even nicer! I can leave my ND filters at home or forget trying to use a McNally Tree in high speed sync mode with my Nikons. My own complaint is that in dark scenes the AF assist light doesn't come as often as it needs to. If you're using strobes without modeling lights or ones with weak modeling lights this is going to be a problem when you're trying to knock down the ambient light in an exposure. It's also more than capable in the studio. So yes, I've been using it for some actual work.
A few reviewers like the JPEG output of this camera and while it's not bad the defaults are a bit contrasty for my liking. The standard film preset tends a bit warm too, overall I like the Astia Soft setting the best. The RAWs on the other hand have an amazing amount of range. I'd put the X100s next to my D800 any day in terms of dynamic range. Blown highlights recover pretty nicely and the shadows are low noise. The lack of a filter on the X-trans sensor makes it amazingly sharp too, the lens isn't bad either. I could make some major prints off this camera with zero problems. Darktable will sometimes struggle with the RAW files, especially if the dynamic range setting is set on auto, but making some adjustments in the Shadows and Highlights module usually clears that up.
It's not all smooth sailing though. The battery life is less than spectacular, even with a brand new battery. The power meter is particularly useless. It goes from full battery to flashing red and powering off rather quickly. The "only down one bar" stage lasts about ten minutes. Get a spare or two since they're cheap. The third party batteries work well. I've heard some people complain about the performance and interface. I can't note anything in particular as I left it in high performance mode and there it seems to handle about as well as my D800/50mm combo. Other Nikon lenses seem faster and more responsive but they're bigger too. Autofocus speed isn't bad but don't expect to shoot anything terribly fast with it. But the X100s wasn't really designed with that in mind. The menu system isn't anything to write home about but it's more than serviceable. I've seen worse that's for sure. Once you find where all the settings are it's quick to move through. The shutter speed knob is hard to get to when you have a remote flash trigger in the hot shoe. I've been doing some video things here and there lately and I can already see I won't be using the X100s for much of that. Very rudimentary abilities. Longer clip length and some more manual video controls would be nice. The LCD screen could use some improvement. It's almost overly bright and has a lot of contrast so everything looks washed out, it's sometimes good for judging composition and that's it. The lens isn't the sharpest f/2 I've ever seen either and there are times I wish it was a bit faster. But I say that second thing about every lens I've used.
Which brings me to my final point. When I first started using the Fuji I called it the Python of cameras. No, this doesn't mean it's a big snake that squeezes its food to death. It's a reference to an XKCD comic about a programming language. The X100 series, for all its faults, excels at one thing: getting out of the way. Once the camera is dialed in it just sort of goes. It's inconspicuous nature means you can have it on you most of the time and no one notices. This is where the opening line of this post comes into play gear doesn't matter, until it does. The X100s has literally, almost single-handedly, gotten me excited about photography again. It's not going to replace my Nikon kit any time soon but it has taken over more than I thought it would. The X100s is the Miata or Lotus of cameras. It's not going to win any speed or power benchmarks but it's nimble and has an appeal all its own. Bros will still roll past you in their Mustang, GT-R, RS or other higher powered sports car and try to yell at you about power or torque curves but at the end of the day you're the one still smiling. It's "simplify, then add lightness" in a camera format.
While I still don't think a replacing my Nikon system with mirrorless is in the cards soon the Fuji X-series just jumped to the top of my list. Even then I'll probably keep the Nikon FX kit around and get use the Fuji stuff in lieu of buying more anymore Nikon crop sensor gear. I've shot literally hundreds of photos with the X100s over the last couple of months, more than the last half of 2015 total and I can't see myself putting the Fuji down anytime soon.
