I have Fluke 17B+ DMM. When trying to measure DC current, the readings are constantly fluctuating. I tried first with a 9V 1A AC-DC wall adapter and the readings were jumping between 0.485 to 0.300 and then down to 0 A. This pattern keeps on repeating. When I used the same DC source but with a 5V buck converter I get a stable 1A reading. I have tried with different probes and another similar DC adapter but this behavior persists. Unless I use a regulator or measure current in circuit, the current measurement is not stable. Is my DMM gone bad, or could there be some other issue?
I assume that the multimeter should read 2A, why is it only 0.358A? If this is how it is supposed to be, why? If I add a load, how do I measure that this load is being drawn, does the multimeter need to be in series?
Non-static variable cannot be referenced from a static context 24% tax on first pay in the UK? Quite a similar thread to others I've seen here - hope I'm not repeating the same questions again!   I just got my first payslip after arriving in the UK and noticed that the tax is far higher than the HMRC rate for my salary bracket.     I did some research but couldn't find any reason why I would be taxed at 24.23% of my gross this month AND then an additional amount for NI.    I have about £640 back pay from April that is only being paid now,but even so, it doesn't explain the rather large discrepancy between the HMRC rate and what I'm seeing here.   Any ideas? I think some good words would be conflicted, or confused. As an example of context, think of someone who believes in freedom of speech, but, at the same time, they would support banning comedians who make jokes about certain issues that person cares about. What is the benefit of launching a satellite "a few days before the monthly report" I've seen this hint in the game as well as on this site and I've been wondering if there is any specific advantage to launching satellites closer to the monthly report rather than any time during that month.  The way I see it, monthly maintenance costs are taken out during the reports (correct me if i'm wrong), so regardless of when you launch it during the month it would cost the same.   Is the benefit of holding on to them longer simply a safety net in case some countries go into the red during that time? Can I install items on Ubuntu, without using the command line?

Vertical line for the the right margin in Notepad++ Set the QGIS display to show decimal degrees? Using QGIS 2.6.1 Brighton. I am trying to set the CRS for the project to display Decimal Degrees, where it is defaulting to Feet. I can change it in the Properties Dialog, but it does not change it, it is just staying on Feet. How do I change it?  Edit: this layer was imported from a shapefile where it was internally set to Feet. I was able to get the vendor to supply one with Decimal Degrees so my problem is gone. Still would love to know if there was a way to do it myself from within QGIS. I'm looking for an easy and robust way to strip all the comments from a listing. My approach (passing \@gobble to the commentstyle key) correctly removes all the one-line comments and block comments. However, the white space left behind by by block comments remains, creating useless gaps in my listing. See the screenshot below (the red rectangle is my emphasis).

In both cases it launches a child shell. Using round function in QGIS expression? I created a grid of rectangular polygons with the Create Grid function, from the Vector Creation group of the Processing Toolbox in QGIS 3.4.2. The rectangles measure half a degree of longitude by half a degree of latitude.    When I want to label the polygons, I write an expression that rounds the values of latitude and longitude attributes to 2 decimal places, since the attributes created in the grid brings many decimal places.    But the round function rounds the values badly.    I know that I can create new attributes that express the coordinates with fewer decimal places and label the entities based on those attributes, but I was struck by the behavior of the function. I expected it to round to the nearest value.    Does anyone know what the problem is that the round function wrongly rounds off the decimal number?

Comprehensive list of tools that simplify the generation of LaTeX tables I like to know when a dying star collapsed into a black hole, is there anything inside or on the event horizon that is interacting with higgs field? Does Kylo not know the fate of Darth Vader? It seems Kylo has an obsession of Darth Vader and has an interest in the dark side because of it.   Does he not realize that Darth Vader turned good and helped destroy the Empire (Spoilers?)? I feel like Kylo would've seen how much better the Light Side was as it was able to turn Vader from the Dark Side if he had known this.
