Q: Any ideas on why this question didn't get any responses

I asked this 17 days ago (although I revised the title later). I don't expect miracles (although sometimes I get them ;) ), but I am surprised at getting nothing. Is there something I can do/could have done to improve the question? Should I repost this somewhere else such as SE Unix and Lin...

TheWanderer

I'm so confused...

I've got 1600 words

in LibreOffice, it's over 5 pages long

when I print that exact document, it's 4.5 pages long

when I paste it into Word Online, it's exactly 5 pages long

Why should one use gdebi to install Google Chrome? Why such a common app isn't available from Debian (or Ubuntu) formal repos? Thanks.

Please tag my profile here.

guiverc

Debian can't as it doesn't meet their standards. Google have to give Canonical permission for Ubuntu; which Google hasn't done. (re: google-chrome in repos)

oogle probably have a MOTU under their employee, so they could possibly put it in universe themselves, but I doubt they ever will...

@user9303970 licensing issues.

So I spent a few hours testing my video capture card today.

I can't confirm for certain that it records 1080p @ 60fps since the only two machines in the house with USB 3.0 ports have underwhelming i5 processors.

My desktop would be more than capable of testing this but it doesn't have a USB 3.0 port :|

(I may look into getting a PCIe addin card for that.)

After tweaking the settings in OBS, I was able to record 1080p @ 30fps on my laptop (with the i5).

And yes, I can confirm that it works perfectly on Linux.

:D

All in all, it seems to be money well spent.

@muru wrong duplicate: askubuntu.com/q/1008955/507051 – OP asks for things like cheat or tldr rather than apropos! I want to add answers covering those on my terminal help Q&A, but didn't have the time yet.

@muru thanks!

You can @-ping me on the post. The dupehammer wielder gets notified (I got confirmed it a few days ago).

^That's why I went for the apropos one.

@muru really? that's useful, but it didn't show you in the mention list…

@dessert yep, it doesn't show me in the list but I do get notified (like people who edited post).

Q: Copying MySQL Database via FTP (FileZilla, Ubuntu, Zabbix)

I have recently discovered that we are not backing up our Zabbix database and i was wondering if it is possible to take a backup via FTP on FileZilla by essentially copying the files from the mysql directory? In the long term we will have a script to handle this properly but i want to make sure ...

Q: Run C++ program across computer on network

I have a c++ program that is multithreaded. I believe the throughput would increase if I could run it in the other computers connected by a switch. All of then are using the same OS(Ubuntu). Is there a way I can do it without changing the code? If I need to change the code what should I look for?

@NathanOsman isn't that basically what taxes already are, but not mandatory?

Byte Commander

You usually don't get a tee-shirt for paying a trillion dollars of taxes though, that's a great deal.

Thijser

@ByteCommander I think that if you pay 1 trillion in taxes you can probably ask for a free shirt.

That's almost as much as the top 20 richest people's net worth together.

Byte Commander

You'd probably get that one amazon.com/Mens-Deplorable-Taxpayer-Shirt-Cranberry/dp/…

Thijser

@ByteCommander I would probably get one with a Dutch flag on it.

Anyway from what I understand past a certain level of wealth you can just walk into a shop and they will give you pieces of clothing for free, just to boost their brand.

6:07 PM

so I have a quick question about bitwise

    vis |= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
    vis &= ~(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.NAVIGATION_BAR_TRANSLUCENT);

that code there

I'm guessing the OR operator (|) means bitwise add

and the AND (&) means bitwise subtract, when combined with the ~?

(this is Java)

Q: How to ensure all Ubuntu secondary software I have after install is drivers (GPU/SPU), terminal emulator, FIrefox, Libre office, and software center?

I have installed Ubuntu 18.04 beta and I feel it comes with too much software I just don't use and doesn't need. About 40 secondary applications I personally don't use, I did: sudo su apt-get update y && apt-get upgrade -y && apt-get autoremove -y && apt-get clean -y How could I then remove ...

ubuntu

Benny

~ is like not

int a = 5 = 101b

so

~a = 010b

so in your question is mean, every flag instead the SYSTEM_UI_FLAG_LAYOUT_STABLE and NAVIGATION_BAR_TRANSLUCENT

TheWanderer

but what about the AND operator?

Benny

but vis get &= so ...

it's depend on vis value

TheWanderer

6:23 PM

the starting value is unknown

is it safe to assume, though, that the first assignment is "adding" those integers, while the second is "removing" them?

Benny

it's mean

TheWanderer

?

Benny

if "vis" has this 2 flags, remove it

TheWanderer

yeah

Benny

if he not has this 2 flag, do nothing, and don't change "vis" current flags vlaue

TheWanderer

6:27 PM

perfect

Benny

:)

TheWanderer

I just needed to understand it to see if I had it right

and does this: (curVis&SYSTEM_UI_FLAG_LOW_PROFILE) != 0

Benny

0&0 == 0 , 0&1 == 0 , 1&1 == 1

TheWanderer

so (curVis&SYSTEM_UI_FLAG_LOW_PROFILE) != 0 (if true) means that curVis "contains" that int?

Benny

if (curVis&SYSTEM_UI_FLAG_LOW_PROFILE) == 1 is mean curVis has this flag

other wise it must be 0

so he don't have it

TheWanderer

6:29 PM

perfect thanks

now I just need to figure out what ~ does in Smali :p

Benny

give me code

i know smali

TheWanderer

you do?!

Benny

yea

TheWanderer

there are dozens of us!

like, I can understand and write Smali, but nothing too advanced

like bitwise ops

will you be avail tonight (EDT)?

Benny

now i got to go now

TheWanderer

6:31 PM

OK

Benny

but leave me the question i will try to help

:)

TheWanderer

I'll look up a reference

Benny

you can always type a small program in android , and then use apktool, to unpack the apk, and then get what you need in smali code.

TheWanderer

yeah

Q: Running any command returns "Cannot allocate memory" on Ubuntu Server

I’m using Ubuntu 14.04. Recently, when I login via SSH with my user with sudo privileges, every command I run results in a “Cannot allocate memory” error. Here are a few I tried at my console myuser@mymachine:~$ whoami -bash: fork: Cannot allocate memory myuser@mymachine:~$ uname -a -bash: for...

server bash ram reboot memory-usage

@Wietlol It may have just freed some memory in the meantime ;)

Wietlol

@dessert yes, but I assume this means internal memory

ram

there was literally 1 second between those two calls

and the free memory before the "cannot allocate memory" one was pretty much the same as after

dessert

@Wietlol but not exactly – I suppose free doesn't need much

Wietlol

but free does show me the amount of free memory right?

afaik, that is what it is made for

dessert

@Wietlol oh, wait – I didn't pay attention to the output, sorry xD

that is weird

yea, but i am not sure if the actual problem is that i am out of memory

i assume that a process could reserve all memory and then just gets killed

i mean, potentially, but i find it hard to believe i have such a piece of software on it

Q: Node JS (-bash: fork: Cannot allocate memory)

Here's the Node JS I'm running at the beginning of the script to clear the garbage collector and then logging the available space: global.gc(); var bytes = process.memoryUsage().rss; var GB = (bytes / 1073741824).toFixed(5); g.heapMessage = "MEMORY used in bytes: " + bytes + ", in GB: " + GB + "...

Wietlol

that is not me...

but it might be relevant

dessert

@Wietlol that's a heck of a coincidence, maybe it's triggered by a recent update?

Wietlol

could be but i doubt it

i have had this issue the entire week

now im tired of it

dessert

@Wietlol I quite believe it.

RobotHumans

Opinion question, on which SE site would you ask "I'm setting up a POS for a guy who bought it, had it installed, and it was supposed to have all UPCs out of the box. Meanwhile, he's sitting there hand entering product UPCs and prices. He had someone send him a price dump with all the UPCs, but now I need to find a way to figure out which tax rates apply to which products for the DB migration/import."

dessert

11:00 PM

@Wietlol good luck finding the solution, I'll go to sleep now – see you!

Wietlol

ty, gn

@RobotHumans you are setting up a piece of shit?

RobotHumans

Point of Sale, but yes. It's weak hardware.

Wietlol

(on a side note, i am not sure i understand any of it, so i cant answer your question)

RobotHumans

I could in theory set all tax rates to 7%, but food(milk, bread, eggs) here is not taxed at the same rate as energy drinks or whatever. So, I can't just say "grocery is 2%, everything else is 7".

dessert

@RobotHumans (still around) isn't this generic programming? simply stackoverflow.com/search?q=[sales]+tax I'd say…

the sales tag seems related

RobotHumans

11:07 PM

I wasn't sure if it would go over better on SO or the database one. I think I'm more likely to get someone that knows point of sale systems on the database one than SO, but I WAS asking for opinions.

dessert

@RobotHumans valid point, I forgot about database – I'd ask myself which dimension of the problem is most unclear to me, and ask at the corresponding site to get help for it

RobotHumans

That's a relevant tag though. I'll do some looking. Seems like most of it is "We developed" programming questions though, not "solutions"

dessert

welcome to the internet, first dig through a pile of crap to find a diamond

RobotHumans

I'm only worried about how to get values to put in that one column. I'm not worried about how to fetch, retrieve, organize, or anything else programatically. I can sort that easily.

> "Go 1.10 is the last release that will run on Windows XP or Windows Vista. Go 1.11 will require Windows 7 or later."

XP is becoming unusable now.

No up-to-date browsers, no recent Qt releases, and now this.

RobotHumans

11:13 PM

That's funny. Same guy, same gas station had a windows box that was running XP that deactivated itself and gave him a 30 day warning. So, he bought one that had 7. The guy had used the product key more than 5 times, so it deactivated. I just shake my head at these bottom dollar people sometimes.

Nathan Osman

Yeah.

RobotHumans

I think I'll hand him a liveCD one of these days, when he gets fed up with the Windows licensing thing and just see what happens. I wouldn't get paid obviously, but I think they only use a web browser on their UHAUL system.

I don't know why linux isn't their deployment pattern...

Wietlol

@dessert in case you are interested, it might have been gnome that messed with the memory

it turns out that having a desktop environment is not a good idea on a vps

RobotHumans

Ah, it's such a common problem, there's a service for it accuratetax.com/signup arg.

I want to help the guy, I really do. But problems will be problems, and not wanting to pay for it will always be not wanting to pay for it.
