New Camera, and resultant stuffs…

Hey, um, ah…

I ordered a new camera body a while ago, and it came on Wednesday (it’s Friday).  I have been playing around with it, so I have been doing some test shooting, and I am doing a bit of a stuff with that.  So yesterday I shot over 200 pictures, and I did the sorting to get them handled.

With the camera I am now able to shoot video, and have done some test video shooting.  But, I’m not sure what will happen with that.  It’s not a “normal” thing for me, but I think that some of that could end up coming up.

In the past I have really wanted to do more video production stuff, and I have really been trying multiple different ways to manage to do that better, so I have to say that this seems to work quite well for me.

Now, there is the one thing that has come out of the ability to film, and post videos, I have setup a PeerTube instance (sign ups are available, but currently somewhat limited).  And am in the process of setting up a Mediagoblin instance, which will have our photographs on (once I have set this up).

It has been a while that I have been trying to get the Mediagoblin instance up, and it has been a bit of a trick to get it as far along as I have it setup.  So that’s not really up yet, and I hope that it is “soon” that it will take a while to get setup.

Right now I am going to import the photos I have taken so far today (probably today’s photos in entirety) and start to sort them, hopefully down to 40 or fewer photos.  I may even start to look at some editing of them if I get around to that.  But I think I’m going to consider looking at MediaGoblin to see if I can get it done, or at least get closer to it…

OK, um, yeah, I’m streaming on Picarto right now, and I’m recording, and will be posting it on the PeerTube when I get around to it.  I will probably be doing a bit of a post once I posted on PeerTube.

So, here this goes, and I’m going to start working on those photos.

My thoughts on eFail “vulnerability” with “PGP” s/mime etcetera…

This has to do with improper handling of HTML emails.  And is said that it could “expose plain text”.  The “attacker” needs to compose a message, which contains a malformed multi-part mime message, which they then encrypt, and they can then expose the plaintext of that message with some browsers which improperly handle these messages.

In other words, the attackers can expose the plaintext which they put into the message.  And, apparently this is an “old bug”.  So why all the cloak and dagger?  I am not entirely sure, but I have a suspicion that some “security researchers” are almost “more in it for the prestige” than they are in it to actually provide genuine help to people.

This was announced by the “security research team” that “more in 2 days when we release our paper”.  They released a “pre-release” version to EFF who (in my opinion) jumped the gun and said that there was a good reason to stop using these tools entirely, and that you should instead use a centralized tool instead.

The “research team” had no reason to disclose that they would be “releasing a full paper” in the public manner that they did.  At least I see no evidence that really there was such a *severe* threat that it was justified.

Further, I don’t know that EFF really did *any* due diligence to make sure that the “flaw” which is disclosed, was one that posed a severe security threat.

So, what’s in it for EFF, and the security research team?  I can’t quite see what is in it for EFF, but the security research team gets another notch in their belt for being “appropriate corporate citizens.”  But the fact is, what *they* did was entirely inappropriate as the spread a bunch of “fear uncertainty and doubt” (FUD) which they actually have *refused* to actually talk to anyone publicly about.  This may also be true of past behaviours.

Essentially, this appears to be a case that an “attacker can compose an email that they can read when you read it.”  Now the *possible* leakage that may exist (assuming this isn’t patched) is that the attacker can tell *when* you read their message.  But to do so requires about 4 *different* bugs to exist in your mail software.  And “deleting” or “disabling” these features is not warranted.  Though there *are* mitigations which they deny exist, which should be available to pretty much anyone who uses PGP or variations:

  1. disable automatic decryption of encrypted emails.
  2. disable automatic processing of html of emails.

Both of these options should be available for anyone who is using PGP, and their variations.  And are the recommended settings to the best of my knowledge.

Update and ideas…

I know that I haven’t posted a lot here recently.  I have been working over on the Open Psychology Project mostly on the topic of my “30 Days of Autism Acceptance” which I have been working on since a little bit before the beginning of April, and am still a bit behind.

In June, I plan on writing posts on “30 Days of Science Thinking” which I have the “introduction” written, and scheduled for May 17th.  Though there may be edits to it prior to getting to May 17th.

I have been thinking about writing 30 Days thing for every 30 day month.  Though I’m also thinking of adding February as “30 Days in February” type idea as well, as it just is too long from the end of November to the beginning of April.  And besides April is “always going to be” “Autism Acceptance Month”.

For September, I am thinking along the line of “30 Days of Web Development.”  Though that’s a way from now.

Datse Multimedia Base theme updated

This is really pretty short.  Today I was looking at the Datse Multimedia Base theme, and saw several things that I felt I could update so that it is less likely to cause problems.  I will be posting it here, but check out the github if you want that latest release.

Second Picarto Custom Emote

I was working on setting up another emoticon for my Picarto stream and I wanted to go a bit more through the process of what I created through that. First, let’s look at what the finished product looks like:

Yellow face, with tongue sticking out.

Final Version from Gimp

So, there is where things ended for me. I am not sure why I don’t see it, but I don’t know where I have the original sketch that I started with, though I have an idea (goes to look)…

Photographed sketch

Original Sketch as photographed (scanning is tricky, but I could try to do it).

As with the previous time, I photographed the image, and I end up getting this sort of thing. As you can see, the colour is not what you would expect unless the paper is degrading, so I do a colour correction.

Colour corrected sketch

Sketch colour corrected

Here I have colour corrected it. I do this once I have the pictures in digiKam, and I click on the edit. I try not to have to do too much that way, and this time I think I did a pretty decent job of it.

This is sharpened

Sharpened Sketch

Here we have that image after I have sharpened it. I’m not sure that it makes much, or any difference here, but it does enhance the finer details somewhat.

Then from there, I import it into Inkscape, and then start working on it in inkscape.

I have a few different versions of the SVG which I have available, but unfortunately I can’t display them in a post, and I *think* the only way to put them up would be to create an archive, and upload the archive. I am probably not going to do that until I really start to find good tools which I am really happy with (which probably won’t happen until I start to feel unhappy with the tools I am using, which in a way I’m unhappy with Inkscape, as it seems to run into a situation with how I’m doing things where it gets very sluggish on this computer).

So, after I have worked through the process with Inkscape, I have created the following images:

This is the version out of inkscape.

Full version out of inkscape

This is the picture as I start with things, and has everything all together (this is where I started in GIMP last time). This is very crude as you can see, it is a lot to get this to a reasonable place, as everything is on one layer. I realized that this doesn’t work to get my pictures in a nice editable form with the last one.

So this time, I had everything nicely in layers in Inkscape, and I exported those layers independently. I also made sure when I did that, that I exported the whole “page” so that everything lines up automagically when I import them into GIMP.

The following (out of order) is the layers individually (hmm… let’s try to fix that order). Let’s start with the topmost layer, and work down…

This is the tongue lineart

Tongue Lineart

Just the pink of the tongue.

Just the pink of the tongue

This is the main lineart.

Main lineart

Black from nose and eyes.

Black painting

White for teeth and eyes.

The white colours I use (I see they show up as grey here)

This is the yellow face colour

Yellow face colour

That is the stack as best I can remember it.  The order these are in is pretty important.  I may not have the order correct here, as I am working from memory and what I think makes sense.  There is a layer that I really think I am going to need to create in the future which is a layer of “white background” which will go behind everything else for two purposes.

  • To keep the background colours from bleeding through, as they do with this
  • Provide a light outline to the image, so it will work better on a dark background

After I did that, I started working on cleaning up the messy nature of the image at this point.  Even if you look at it all together:

All layers together before gimp editing

All the layers together

it is really very messy. It needs to be cleaned up.

I have edited this in GIMP, and likewise with my editing process in Inkscape, the saved files of the process do not really work here (I don’t think).

Tongue

Nope, you can’t see it directly…

So, I’m not going to post those, as unless someone wants to work with them, they probably won’t want them.  I may put those files (or access to them) on my Patreon as a tier at the higher end, and they may not be as the usual CC-BY-SA that I use, but copyright, or something else.  Not sure…

So, there is an editing process that goes on in GIMP that is difficult to express without the multiple versions which I end up creating them as.

In the end, I export it as a GIF file, as that is what Picarto uses for emoji.  I think that animated ones will also work, but I don’t see myself creating any of those until I start to get the fairly extensive list of emoji I would like to use.  So here (again) is the final gif image.

Final emoji, it is decent...

This is the final emoji

So, thank you for checking this out. I am getting bits and pieces better together with each new emoji I create. Please check out my Patreon, and either support me there (was stepping away due to a poorly considered change, which then got rolled back entirely), or support me over on LiberaPay.

LedgerSMB install on Gentoo

A while ago, I started to look at installing ledgersmb on this new system (I already have it running on an older system, which I have been shutting down due to fan noise (perhaps more on that later when I find a solution)) and I was wanting to do a new install.

So, when I was doing that, I found out that there is now an official gentoo repository (hey, cool let’s install that, and see where that gets me).  So I installed it, hoping I could have an emerge ledgersmb or something work just like that.

I saw that was not an option for me.  And I stepped away from it for a while.

Today, I looked again, and there seems to be more packages included now, but I’m not sure, and still no package for ledgersmb itself.

So, I started to look at what we currently have, and this will probably be a bit easier (or at least “more proper”) than installing entirely manually, I am installing from the sourcecode which is on github.

There are some packages that I failed to find in portage at that time, but perhaps…  The problem was a matter of not knowing what I was looking for…  So far, it has come together, but not in a simple manner.  Maybe smoother than previously.

Picarto custom emoji

Today as part of my “Open Psychology” work stream, I ended up creating a custom emoji for Picarto, where I was streaming.  I have been in the process of setting things up there, and I was just playing around with some stuff.  So, I did a few different steps (that I can share).  I started by drawing a really simple drawing.

Big grinny line drawing of a face.

This is the photo of the sketch that I did to do a big grinning face for a custom emoji.

I thought that this was close enough to what I want, that I went with that image as my start. Then I went through a few different steps to get that to how I would like to start working with it:

Colour corrected smily face line drawing.

I did some colour correction to get it closer to the original colour.

Rotated smily face.

I rotated it, to get an image aligned the way that I think I probably want it.

Colour corrected, rotated, and cropped smily face

This was then cropped to get it with less extra space (especially with it rotated, it has some weird stuff showing up)

From there I was able to import that into Inkscape. And, let’s see what I still have hanging around to allow you to see my process…

Exported from Inkscape drawing of the grinning face.

Export from Inkscape. This is “really ugly” at this stage.

A lot of what I did in Inkscape I feel that I will want to do differently in the future. This is a very flat PNG, this doesn’t really work for editing in GIMP. But I imported the SVG, which worked much better, but still, it didn’t work the way that I would like as that got imported as a transparent raster graphic.

From there, I did a bunch of editing in GIMP to end up with this GIF file:

Gif of grinning face. Yellow face.

Final result of the editing. Gif file

This is what it ended up looking like before it went into Picatro, and it doesn’t look that bad. Well I don’t think it really looks all that bad…

I would like to in the future save more of the intermediate steps that I go through to produce these.  I like how files end up showing up when I am using digiKam as I can just “save version” as I am editing it.

Picarto.tv stream setup

I have been working today at getting the Picarto stream up running.  I was having very significant problems with what I was managing to stream and I see now, that I just need to drop my frame rate, or I’m going to have too low resolution.  With running it at 10 frames per second (really not good for anything video like) I can have the resolution high enough that people can see stuff.

I had some help with looking at it from a Patreon supporter, so that was helpful.  I think the one thing that still is bothering me with it is that the loading seems to “take forever”.

I also added some information I had from my twitch stream, specifically I have added a link to my Speq schedule.  I will be streaming (at least the “creative” stuff) on Picarto, rather than Twitch.

The 10 fps seems like it will be good enough for most of what I do.  Currently, I don’t know of any faster I can upload like that…

Oh…

Exciting news…

I got a book that is telling me most of what I need for getting my microphone pre-amp built.  I hope that I can get it working fairly soon.  I know it will be a few weeks before I have it.  But I might be able to start working on it in a week or two.  Wish me luck?

Arduino Project – Simple LED

This was from the Arduino Project book I got, it’s not really much of a project as it’s mostly based on “assume nothing” type perspective.

Arduino and soderless breadboard mounted

Arduino Project starting spot.

When I start with a project I have the board setup something like this.  I am currently between projects (as I’m writing this) and have left the existing project setup.  This is how this ends up being setup from how The Arduino Starter Kit sets up your Arduino, and the working surface for it.

I took a fair number of pictures while I was working on this project, and most of them did not really work out that well.  I am not all that happy with this one even.

The project that I am writing about is only using the Arduino as a power supply (though in a way that is an important place to start with it).  So from this we connect the power to the breadboard.

pushbutton, LED, and "power leads"

Components used (missing some (I think) at least duplicate ones, and most wires) for the first project. Pushbutton, LED, and the “power leads”.

These are the components which I used for project.  Well, most of them.  There is a resister that gets used, and there is another pushbutton which is used.  Just a little bit of documenting some stuff.

From here I started to put things a bit together.  I attach the power leads (red and black cables).

Power connected to breadboard from Arduinio

Power connected between Arduino to breadboard.

This is a nice start for the project.  Connected from the power on the Arduino to the breadboard.  It starts here.  Not all that exciting.  But it comes along.

The first “phase” of the completed project, is really very simple.

Lit LED on Arduino development system

Very simple completed LED version. `

This is how the first version of first project works.  It is really simple.  About the simplest version that you can produce.

This unfortunately is the last picture I managed to get a good picture of.  Once I completed this project (which includes two versions with two pushbuttons, one with them wired in series, and then one with them wired in parallel).  Once I finished putting it all together, I worked on starting to get some circuit diagrams together and the first one is this version.

Arduino Project 001 – LED

I will leave this post at this point right now.  I’m going to pull this diagram up in KiCAD and see about drawing the other versions of the diagram.

Arduino Setup

I am not sure if this will end up split in multiple posts or not, but I have two broad topics being the hardware setup (which is basically, I mounted it, and I connected it to the computer with the USB cable provided) and the software setup (which has a bunch of things which I think are rather important to write about).  So let’s start with the software setup, as even though you need to do the hardware setup first, it’s simple, and I didn’t really “learn” anything important there.

Arduino Software Setup (this was done on Gentoo)

OK, so, I expected to run into some problems with this, but I just was looking at the “project book” that I got with The Arduino Starter Kit and the Linux instructions are “please go to the website”.  A bit of problem with even that instruction (and all of the instructions of that sort in the book) first being that arduino.org doesn’t exist as a domain that serves actual content.  And second, some of the specific instructions just are not able to be followed at all.

Arduino provides an IDE (Integrated Development Environment) which needs to be installed (or something similar, which will provide needed tools for that, but we’re going with that, as so far the only alternative I have found is Eclipse, and I have had many problems with Eclipse) in order to work with the Arduino at all.

So, the instructions on the website, didn’t provide anything that looked like a good way on Gentoo (well, nothing specific to Gentoo, and everything else was specific to another distribution) so I looked to see what I could find in my portage directory (/usr/portage by default) and did find it, so dove in with that…

But, but, but…  It isn’t working out of the box…

The instructions I found said some stuff with /dev/ttyACM* which isn’t showing up…  OK so I need to figure that out, so I look at my kernel…  yep, I need to do some stuff with that…

I update the kernel, and I install it in /boot but I don’t “tell grub about it” which is a total rookie mistake (I know to do that, but I just forgot) and reboot, and “darn that kernel isn’t working”…  So i start looking for Gentoo instructions which I have found are often “old” and sometimes very outdated (ie. they not only don’t work as stated, but they flat out don’t work) but in this case, I can say yes, these are really pretty much correct.

I thought (having not realised at this point, that I wasn’t running the new one) that I needed to enable more stuff in the kernel, and enabled the other drivers that are listed on that page (I don’t think I needed them, but they don’t seem to be doing any harm) and then booted into the new kernel.

I can now see the device /dev/ttyACM0 but I still am not getting communication to the device.  And I start digging further as I have missed a step (I hope that is all at this point) and it was setting up user permissions.  I need to add the user I want to use to the group for the device, and that got the device showing up as available.

In the mean time, I start to work through the other options, and the first part says something about packages in “cross-avr” which I don’t have at this point, which actually ends up confusing me somewhat (because it doesn’t say “these may not be available at this time” oh look it actually says “these packages are not available until after you install crossdev” so I want to know why you are asking for something that will fail until such point as I’ve done that).

I have already done some stuff which is further down, so my process might be “somewhat broken” and I know I did stuff that I shouldn’t have needed to two twice, twice, or maybe more than that.

I tried to follow the instructions, but there are some problems that I ran into that they don’t get into, namely that you probably don’t want to install crossdev stuff into an overlay that already exists, and it was doing that for me (I haven’t seen if it ended up adding stuff to that overlay or not) and I had to figure this out through looking at the help for “crossdev”.

I had to run the command that is listed as crossdev -s4 --stable --portage --verbose --target avr multiple times to get it to work correctly, but once it did, it simply did (though I have to say, it takes a *long* time for it to happen, and there is no running output to show that something is happening).

Here is a case where Gentoo seems to fail on the “don’t provide enough information” side of things.  Or maybe more “don’t provide enough information in a way that it actually allows a person to look at what is being said, and readily find a solution to it from that source”.

I needed to tell crossdev exactly where I wanted it to “put stuff”.  I see no clear place where that information exists on the Gentoo website.  I don’t really know if where it was picking “automagically” was “wrong” other than it was putting stuff in an overlay which had no reference to…

Once that got installed, I then tried the “check this out” thing which failed earlier in the process looking at the crossdev-adm stuff.  I’m not sure I needed to do that or not really…

In the end, I found that I needed to create a symlink that it says “you also need a workaround” which somehow I put a “may” in…  Now it seems that everything is working (after once again trying to install the arduino ide, which I don’t know I need to do).

I then looked at the information they have with eclipse.  I couldn’t really get it working “well enough” to want to switch unless I could do my existing stuff better with it, but actually getting any of that setup was a pain (it took “forever” for it to finally tell me what I needed to do, in fact I left it overnight and it was saying “hey why not do it this way”).  So I am sticking (at least for now) with the arduino ide.

Hardware Setup

This was pretty much trivial.  The issues I ran into were of the “dropping little bits, but finding them quickly” sort.  Instructions that were in the “Project Book” which I found quite understandable, and it looks like (so far) I have done nothing problematic.  So now to play more with this…
