Grab an Image From Your O-scope The Easy Way

-

The Rigol DS1054Zed is the oscilloscope you want. If you don’t have an oscilloscope, this is the scope that has the power and features you need, it’s cheap, and the people who do hardware hacks already have one. That means there’s a wealth of hardware hacks for this oscilloscope. One small problem with the ‘Zed is the fact that capturing an image from the screen is overly complicated, and the official documentation requires dedicated software and a lot of rigolmarole. Now there’s a simple python script that grabs a screen cap from a Rigol scope.

The usage of this python script is as simple as plugging the DS1054Z into your USB port and running the script. A PNG of whatever is on the screen then appears on your drive. Testing has been done on OS X, and it probably works on Linux and Windows. It’s a simple tool that does one job, glory and hallelujah, people are still designing tools this way.

This work was inspired by the efforts of [cibomahto], who spent some time controlling the Rigol with Linux and Python. This work will plot whatever is being captured by the scope in a window, in Linux, but sometimes you just need a screencap of whatever is on the scope; that’s why there were weird Polaroid adapters for HP scopes in the day.

Yes, it’s a simple tool that does one job, but if you need that tool, you really need that tool. [rdpoor] is looking for a few people to test it out, and of course pull requests are accepted.

Takeaways from the outcry over Dior’s Johnny Depp perfume ad: Tuesday Wake-Up Call

-
Welcome to Ad Age’s Wake-Up Call, our daily roundup of advertising, marketing, media and digital news. You can sign up to get an audio version of this briefing on your Alexa device. Dior pulls a perfume ad starring Johnny Depp Yet another luxury brand just had to backtrack after a culturally insensitive move. Dior on Friday pulled an ad for its “Sauvage” perfume, as Business of Fashion reports ; the spot starred Johnny Depp playing guitar in the desert while a Native American dancer, Canku One Star, performed in traditional dress. The company portrayed the spot as “an authentic journey deep into the Native American soul.” But the brand was quickly accused of cultural appropriation. Critics seemed most troubled by the juxtaposition of Native American imagery with the word "Sauvage"—which means “wild” in French, but which also evokes the history of labeling indigenous groups as “savages.”  LVMH-owned Parfums Christian Dior had apparently tried to proceed cautiously. It coo

When the coronavirus infodemic strikes

Social media sites are stepping up their efforts in the war against misinformation… specifically, the coronavirus/COVID-19 infodemic . There’s a seemingly endless stream of potentially dangerous misinformation flying around online related to the COVID-19 pandemic, and that could have fatal results. It’s boomtown in fake-news land riding high on the wave of people being left with their tech devices 24/7. I myself regularly see everything posted online from “hand gel is an immunizer” (nope) and “children can’t be affected” (not true) to “UK rules mean domestic abuse survivors have to stay with their abusive spouse” (absolutely not true at all and hugely dangerous to claim).  We even have engineers being spat on thanks to 5G conspiracy theories potentially resulting in transmission of coronavirus . Turns out a global pandemic is a lightning rod for pushing people to conspiracy theories galore, to the extent that some folks have to go hunting for guides to wean their family members a

Patch, Or Your Solid State Drives Roll Over And Die

Expiration dates for computer drives? That’s what a line of HP solid-state drives are facing as the variable for their uptime counter is running out. When it does, the drive “expires” and, well, no more data storage for you! There are a series of stages in the evolution of a software developer as they master their art, and one of those stages comes in understanding that while they may have a handle on the abstracted world presented by their development environment they perhaps haven’t considered the moments in which the real computer that lives behind it intrudes. Think of the first time you saw an SQL injection attack on a website, for example, or the moment you realised that a variable type is linked to the physical constraints of the number of memory locations it has reserved for it. So people who write software surround themselves with an armoury of things they watch out for as they code, and thus endeavour to produce software less likely to break. Firmly in that arena is the size
