Someone agrees to review my Nginx-WordPress bootstrapper? I greatly improved it after getting many criticisms (and literal shouts) and gave hours upon hours to learn how to design and develop that.

Alright. I apologize in advance for all of these.

Here we go...

Did you make these Nathan?!

Nathan Osman

No.

Sadly, I can't take credit.

Stole them from a Slack group I'm in.

Seth

Ah. They are quite good though! xD

Nathan Osman

IKR?

Now I just need someone to actually give on to lol

PowerShell is weird. That is all.

@NathanOsman It is very different.

I used to dislike it, but it's growing on me. Slowly.

I like that it's open source.

Journeyman Geek

@Seth @NathanOsman heh. MS is getting oddly linux friendly...

You can probably run (newer) ASP.net/MSSQL stuff on a linux box exactly the same way you'd run, say a python app. Which is kinda disorienting.

Seth

06:07

@JourneymanGeek they've had to redefine themselves. Their previous business model wasn't making them enough money, apparently.

Or that's the party line, anyway.

But not that it isn't cool. Being able to use .NET on Linux is really awesome.

Q: Installing Linux on Mac OS X Not Finding Disk Partition

I am trying to install Linux (specifically Ubuntu 16.04) on my Mac OS X 10.13.3. I followed the instructions here. I created a USB installer with UNetbootin, installed rEFInd, created a 124 gb partition of my hard drive and even booted ubuntu successfully from the USB drive. However, when I try t...

Feb 8 at 16:06, by Thomas Ward

that should be a user-specific decision whether they install certbot and things

@user9303970 I'm not really proficient in these things, but you already got a lot of feedback here and it doesn't seem like you did anything about (at least) these flaws. What gives?

user9303970

09:39

dessert, of course I did: I declared it as non-communal (hence there is no problem with Certbot there, or intended lack of documentation), I deleted the while-heredoc Thomas mentioned, I no longer source anything besides variables/aliases per Thomases criticism, I reduced the number of dirs and file for better architecture, as recommended by terdon, I united some files and so forth.

Between the recommendations and now, I added documentation but I deleted it the moment this project was declared non-communal. So, after all my changes, I ask for a second feedback. No one is obliged to help, of course, I'm fully aware to that...

Huh, one person, multiple accounts in the question and comment to the answer? He or she seems to comment in the name of the asker. askubuntu.com/questions/1006476/…

dessert

@Oli This answer recommends rename with $N, which seems to be really simple compared to your sprintf approach, but I can't get it to work – is this refering to Ubuntu's prename or anything else?

Oli

17:12

@dessert I think they renamed it to file-rename (with alternatives symlinks to rename) but yeah

Oh that answer... I'm not sure

Seth

hey @Oli! How's life?

dessert

17:32

Oh, I even asked about the different rename commands once: askubuntu.com/q/956010/507051

Seems like OP is speaking about yet another one there: plasmasturm.org/code/rename

@dessert about the renames:

Q: What's with all the renames: prename, rename, file-rename?

On my Debian system (well, my LMDE system, but close enough), I have at least 3 different rename programs: /usr/local/bin/rename : This is a Perl script, written by Tom Christiansen. Oddly enough, I can't seem to find which package installed it: $ dpkg -S /usr/local/bin/rename dpkg-query: no ...

@terdon Oh, I guess we had the same question there. Why doesn't SE already have a cross-linking feature where one can link questions from different SE sites? Would be quite helpful here IMO…

So I decided to be brave and buy one of these: amazon.ca/gp/product/B077KRWVPJ

I'll let y'all know how it works. I'm also curious to see if it works over USB 2.0. If it does, then I will try connecting it to my Pi.

Being able to remotely control a DSLR using a Raspberry Pi would be amazing.

IanC

@NathanOsman Nice! Let us know, though I think USB 2.0 might not handle the rate necessary for high definition, but who knows :)

what do you want to control a DSLR remotely for?

Nathan Osman

21:27

@IanC It claims to have an onboard MPEG4 encoder. So it should be feeding a compressed stream to the PC. USB 2.0 has a theoretical maximum of around 50 MB/s which should be more than enough for 1080p at reasonable bitrates.

@IanC That's not actually the original purpose for buying it. I want to be able to record video indefinitely (normally, recording is limited to 20 minutes).

This will allow me to record from live view instead of using the camera's video encoder.

But I still think it would be cool to use a Pi to control the camera.

Did I ever show you the video from a couple years ago of the bird's nest I captured with my Pi?

IanC

@NathanOsman that's odd, so even if you have a very large storage space you can't do stuff like a timelapse video with your camera? Because of that constraint?

@NathanOsman No you didn't, send me a link!

Nathan Osman

I cannot record a timelapse video but I have an intervalometer, so I can record images at regular intervals.

(Which are of higher quality anyway.)

IanC

yeah, I think that's actually the right way of doing timelapses lol

recording indefinitely is more of a workaround when you don't have a intervalometer

Nathan Osman

Here's the bird's nest:

Robin Feeds the Chicks

►

I recorded that using the Pi camera.

And here's a timelapse I shot earlier this year with the intervalometer:

Timelapse of Clouds Rolling By

►

IanC

That's cool!! I think I can see the possibilities now, of stuff you would only be able to record remotely

Nathan Osman

21:36

The only thing I need now is an AC adapter for the camera.

IanC

specially things involving wild animals, that would scare away personally :)

@NathanOsman what is the charger like? I think that won't be really hard to find if you get the input voltage/amp right

Nathan Osman

Apparently ACK-E8 is what I'm looking for.

Canon doesn't even sell them in Canada :|

(Not to mention that it's grossly overpriced.)

IanC

you can't find them online locally? Last resort could be get them that from AliExpress

but it would take a while..

Nathan Osman

Amazon has some.

amazon.ca/ACK-E8-Adapter-Replacement-Coupler-Battery/dp/…

IanC

they deliver to canada right?

Thomas Ward

21:42

Amazon Canada might

Nathan Osman

Oh yes.

That is Amazon Canada.

Thomas Ward

standard Amazon will be painful to ship international :p

Nathan Osman

^--- this

Thomas Ward

@NathanOsman can't tell from the onebox on a phone :p

Nathan Osman

amazon.ca/...

Lol.

IanC

21:43

I opened the website but didn't even notice the ca lol

Thomas Ward

@NathanOsman "...***on a phone***"

Nathan Osman

I wish I had a multimeter.

Thomas Ward

can't get link data easily in the chat 1boxes on a phone

Nathan Osman

I could verify it was outputting the correct voltage.

IanC

well, go ahead and buy it! 16.99 is a little above the price I saw on aliexpress on a quick search but not big enough to compensate waiting months for it to arrive

@NathanOsman cant you find one of those cheap ones on some electronics shop?

Nathan Osman

21:44

I'm not sure I come out ahead using a cheap multimeter to test a cheap power supply :P

Something somewhere along the line has to be high quality :P

IanC

I can't defend the idea

hahaha

but I think the precision isn't that bad in the covered voltage/amperage even on the cheap ones

just don't use it for high amperage, I did it when building a AC to DC supply and almost burn mine :D

that's not even the worst I did, I didn't have any electronics shops to build a nice case with some plug connectors and "alligator clips", so the DC supply is like a box with lots of wires coming out of it solded to a paper clip lol
