    1. How do you design a Proof of Concept project for a new dev/test tool?

      Input wanted for an article.

      Let's say that your company is considering the purchase of an expensive new application to help in the company's software development. The demo looks great, and the feature list makes it sound perfect for your needs. So your Management arranges for a proof of concept license to find out if the software is worth the hefty investment. The boss comes to you to ask you to be in charge of the PoC project.

      I'm aiming to write an article to help developers, devops, and testers determine if a given vendor's application meets the company's needs. The only assumption I'm making is that the software is expensive; if it's cheap, the easy answer is, "Buy a copy for a small team and see what they think." And I'm thinking in terms of development software rather than enterprise tools (e.g. cloud-based backup) though I suspect many of the practices are similar.

      Aside: Note that this project is beyond "Decide if we need such a thing." In this scenario, everyone agrees that purchasing a tool is a good idea, and they agree on the baseline requirements. The issue is whether this is the right software for the job.

      So, how do you go about it? I'm sure that it's more than "Get a copy and poke at it randomly." How did (or would) you go about designing a PoC project? If you've been involved in such a project in the past (particularly if the purchase wasn't ideal), what advice could someone have given you to help you make a better choice? I want to create a useful guide that applies to any "enterprise-class" purchase.

      For example: Do you recommend that the PoC period be based on time (N months) or workload (N transactions)? How do you decide who should be on the PoC team? What's involved in putting together a comprehensive list of requirements (e.g. integrates with OurFavoredDatabase, meets performance goals of X), creating a test suite that exercises what the software dev product does, and evaluating the results? ...and what am I not thinking of, that I should?

    2. How to cast internet videos to my Chromecast? (It's not as simple as it seems!) [SOLVED]

      Recently, I've been posting here about all sorts of theatre that's available for streaming during the pandemic lockdown. Sounds like fun! But when I actually try to watch some of it... I'm having technical problems.

      My Lenovo Yoga tablet won't cast from Chrome. At all. The option just doesn't exist in the Chrome browser on the tablet. The only way to cast anything is to open an app - but the videos I want to watch are on a webpage. In Chrome. Which doesn't have a casting option. Not helpful!

      So I go to my desktop computer. It can cast from Chrome to Chromecast. But the result is video only, because "casting tab audio is not supported on this device." I tried Googling that error message, but I ended up getting flummoxed. The Google Help pages don't even mention this error, and other tech blogs are too complex for me to understand.

      The Chromecast works fine. It accepts input (with sound) from other sources. It's just webpages (like YouTube.com and Vimeo.com) I'm having trouble with. I managed to watch one video last week, but I had to resort to installing the YouTube app to make it work. But not all the videos are on YouTube.

      Any ideas?

      This past Black Friday, I purchased the highly acclaimed Phillips SHP9500, and I'm quickly becoming a fan. Open-back headphones are the opposite of in-ears, as you can hear yourself talking clearly, even when there is audio playing. While I don't think the sound quality itself compares to my Audio Technica ATH-M40x's, it's a fair trade-off. I'm looking for possible upgrades to improve my experience, chiefly a microphone for voice chats (many of them due to covid). Please share your thoughts and experiences. I need to make choices soon.

    4. When I press the right trigger on my game controller, my system's audio crashes. Probably the weirdest bug I've seen yet -- anyone feel like helping?

      due to the looming pandemic forcing everyone to stay inside, I've recently decided to get back into video games. I did a fresh install of windows 10 the other day, and tried to play a few games with my controller. I found that whenever I press the right trigger on my controller, my computer's audio cuts out system-wide immediately and does not come back on until I restart.

      The controller is a wired Afterglow for Xbox 360 PL-3702.

      Windows 10, version 1903.

      I see two audio devices under Sound, Video and Game Controllers in Device Manager: a AMD High Definition Audio Device and a Realtek Audio device.

      I've tried updating drivers for my controller and audio controllers.

      I've reproduced the issue and collected logs of it following the steps here. If you know how to read these I'd be happy to send you the trace.

      Now, I've tried to look at the trace of this in both Windows Performance Analyzer and Windows Media eXperience Analyzer to try and get a better sense of what's causing this. I see a pretty clear event where a bunch of stuff shows up in the visualizer, but I don't know what any of the stack traces that show up mean. This did not occur on my previous install of Windows on the same computer so I suspect it's related to something with some new Windows "gaming" feature I didn't have before.

      I'm really at a loss as to where to go from here. It's both perfectly clear and completely mystifying. Any ideas?

      I'm trying to clean up my internet presence and move away from at least Facebook and Google. I've come a long way with deleting my Facebook and it's now basically an empty shell for messaging. I've installed Signal and will start the grooming process with my friends and family now. If you have some solid arguments for the change regular ol' folks can understand please share them with me because as we all know "privacy" just isn't enough.

      Next phase is the big one...Google or basically G-mail.

      1. Is there any way to get an complete overview of where you've used your e-mail for a service online?

      2. What e-mail would you recommend?
      2a. I'm OK with paying a bit for overall quality, security and equally important UX!
      2b. I don't use any other relevant Google products like Drive etc. It's just regular e-mail and sign in credentials for other services I basically need

      3. I use a Mac, iPhone and iCloud. Is iCloud a problem? IF this needs to change it HAS to be an "easy" switch and not like setting up a server for myself. Because it won't happen and I'm not skilled enough.

      I would very much appreciate your input :)

      EDIT: Thank you all for your thorough comments!

      This is something I tried before with a Discord group for studying Python, but it was a catastrophic failure. Lots of people showed interest, almost no one showed up at the designated time. Besides, even the one person hardly interacted.

      After that, I started creating an online book/tutorial for beginners (well, anyone that is more of a beginner than me :P), but it was hard to stay motivated by myself — the whole reason for the study group was precisely to avoid that.

      The topic is not defined yet (I'm thinking logic...), but I'm inclined to try it again. Streaming video and/or audio is a possibility, but not a requirement. I'd rather avoid it if possible.

      Any suggestions on how to make this work?

      I have ordered a phone with an eSim this week and I have been reading a bit into it.
      As far as I know so far, you just have to download an app and you can just book some extra data as needed - it seems especially cool because you can just book a local plan when you're abroad instead of getting a local sim card. Which can be more or less a hassle - 2019 I went to South Africa where it was pretty easy to get a sim card at the airport, 2018 I went to India, where it was a hassle.
      I guess for people in the US this is not a problem? Some of my friends have global contracts, and I had that too when I was there via googles project fi. We don't really have an equivalent in Germany

      I found the following pages in case anyone also wants to look into it
      https://esimdb.com/ - this is an overview page about different esims
      https://www.airalo.com/ - this is one specific offer that seems to be the cheapest for Germany, which is where I would try it, since I live here haha

      So my friend has a computer she put together, and after replacing what feels like every single part on the rig, multiple trips to the repair shop, and calling a priest wrestling the demons out of it, it is randomly cutting power and we think the replacement power supply might be just as busted as the last one. Are there decent odds of that being an issue, or could it be something that we are overlooking?

      EDIT: So, I had a car issue pop up and I won't be able to to take a look at at it tonight. Will download the tools you all mentioned to a jump drive and will keep you posted.

      Was there, stayed up the whole time. Really thinking it might be a bad power switch that stuck, so it would turn off randomly. Thanks for all your help.

      FINAL EDIT: So I narrowed it down to the Graphics Card and/or the Cooling System. Running the Heaven Benchmark on Extreme pretty reliably cleans it's clock, especially turning it off and then turning it on again. This happens on the latest Windows Updates, with latest Nvidia Drivers. (RTX 2080) Pulling the card and running the benchmark anyway causes the same issue, and this time it powered on and then back off in a loop. CPU-Z stress caused it to crash, so I'm assuming it's the cooler. Thanks again.

      Also called niter.

      I live near the ocean. Around here we call this "salitre": salt from seawater that becomes airborne, shortening the life span of every electronic. Desktop computers are especially susceptible.

      The only thing I hear in that regard is to just never turn off the computer, since doing so would allow the corrosion to take place at a lower temperature, without circulation, etc.

      But electricity is not cheap, and I put this machine together myself so I don't have to worry about voiding the warranty.

      And keeping the AC on 24/7 is both expensive and unhealthy.

      So I rescued an old TV from the trash, appears to be a Hitachi Rear Projection TV, no obvious model number available, and when I try to power it on, it will display just fine, but it has no audio coming out UNLESS I turn it over to antenna input, in which case it has bone rattling analog static. This is the US where everyone changed over to digital television, so not super helpful, and while I could do some sound splitting magic, that seems like a waste if there are already good speakers. So I have come to you, honored Tildos, for assistance in pointing me in the right direction on whether or not this television's speakers can be saved.

      Hello,

      I have a few questions. I didn't want to wast money so I wanna use what I have in terms of hardware, only the PSU and storage if needed.

      PC:

      • CPU AMD 5 1600
      • RAM 16G
      • SSD 125 GB for OS

      Services I think of running:

      • Node Tor middle relay
      • Node Bitcoin
      • Node XMR
      • Gitea or Gitlab
      • Maybe some service to host files or make a share for lan or a could service
      • Maybe a TS Server or Minecraft

      Questions:

      1. Do I have enough power to run all of this or I am being to greedy? I have raspberry(not pi 4) stopped at home doing nothing I could run some of this services on them if the computer can't handle everything.
      2. Should I virtualize? Can you explain me your response on this?
      3. I thinking of buying a good PSU since I am running this 24/7, should I invest in gold platinum or something like that?
      4. Should I have multiple disks if yes can you explain how much and for what.

      This is will be my first server at home so I would like to hear tips if you think I am forgetting something.

      Thanks in advance.
      Edit: visualize > virtualize

      I have had several accounts taken over, and decided I've had enough. I decided to use a password safe, which I've been wanting to do for years, and finally settled on Bitwarden because it's fully open-source.

      The hangup is I'm unsure how to transition to it. I've logged some old email accounts I occasionally need to access, my new Netflix account (just got my own), and tildes, but I haven't changed my email password, for example (my email password is only used for email).

      For anybody who has done this already, is it best to dig up all my accounts and jump over to bitwarden, or to switch them as I see/use them over time?

      I just moved into a new apartment, and am using a 32" tv in the living room. The TV is already way too small, but I'd rather prioritize spending on the speakers first.

      I thought I could live with the TV speakers, but have quickly realized that they have made watching movies impossible. The dialogue is impossible to hear without cranking up the volume. And then if there is anything other than dialogue, it's way too loud.

      The walls in the apartment are fairly thin, so I'm pretty sure a subwoofer is out of the question. So I was looking at soundbars but keep seeing conflicting advice. There are articles like this that make them sound fine, yet when you go to place like /r/hometheater, everyone despises them.

      So my next step was to look at powered bookshelf speakers. They seemed like a pretty good option, until I went to best buy to listen to them. I'm not sure if they just weren't set up properly or what, but none of them sounded that great. Especially when compared to the tower speakers they had.

      So now I'm at a loss. Should I go with a soundbar, bookshelf, or tower speakers? My budget is under $500.

    16. I believe Google search is restricting what articles I can see in my searches, based on my location. What can I do?

      Whenever I search for information about something - especially about a news event - Google returns me a lot of results from Australian sites. Any foreign sites come further down the list, sometimes even on the second page of results. I've never really paid much attention to this behaviour, beyond some occasional mild frustration at not being able to find local sources.

      However, this came to a head this week when I was searching for a local US-based news article about something I'd read in an Australian news site, so I could post that local US article here on Tildes (I always try to get as close to the source as possible). But, try as I might, I just could not find any good non-Australian articles about this news! It was almost like Google was deliberately blocking my attempts to read non-Australian sites. I mean, it's possible that this news wasn't reported outside Australia, but that's unlikely, seeing as it was Uber's announcement about trialling electric aircraft in Texas and Victoria. That had to get American coverage. But I struggled to find it in my searches.

      I then noticed something I've never noticed before: at the bottom of my Google searches, there's a small line which tells me my current location. It's as specific as my local council area, not just my state or the country.

      Is this location affecting what Google shows me in my searches? If so, how do I remove this restriction?

      For context: I use Chrome, but I only sign in when I'm accessing a Google service (usually the Calendar). After I've finished with the service, I sign out. So Google isn't tracking me as a person, it's just tracking my browser's search activity.

      EDIT: Thank you all. I've already set up DuckDuckGo as my default search engine, and am trying it out.

      Traditionally I've used dark themes for everything I could on all of my devices, as I found it easier on the eyes when I'd usually use my computer (evening - night). Recently, I made the switch back to light stuff as I've been using my computer more for notes and assignments I'd normally hand-write, and I find I get drowsy less and have an easier time using the computer in a bright room than before - I just switched my theme on a whim one morning, so I wasn't expecting that at all!

      So now I'm rethinking all my previous bias about dark themes being 'better' regardless of the situation, and I'm curious if anyone here had any thoughts and/or could point me to some reading on the subject (the subject being the effects of light/dark colours in work or concentration). It's something I realize now might be fairly important, as I'm looking at my screen for most of the day, but never really gave much thought before outside of tracking down the 'Dark' theme switch.

      I'm downsizing my digital life. I deleted my account on reddit, on another phpbb forum and i don't have instagram/facebook apps anymore.

      This subject got me thinking about my music.

      I grab/buy albums in mp3 and i have so many that it's impossible to listen to everything. I don't pay for any service like spotify because i don't like. I prefer to download and/or buy in places like bandcamp where i can download the album.

      I started reading about other codecs like flac and opus. The availability of albums in flac are way less than mp3 and it's a lossless format. If i focus on it i will be forced to downsize my music library.

      The problem is disk space in my smartphone. I'm not an audiophile so i'm not able to hear the difference between flac and 320kpbs mp3. This is where opus enters. This codec gives half the size with better quality than mp3. Soundcloud uses it. A 96kbps opus is the same quality as 320kbps mp3.

      Now that Android can play opus i don't see a reason to keep using mp3. The downside is converting flac files every time i want to put on my phone.

      I could just convert flac to opus and just live with opus everywhere, freeing a lot of space. But i think keeping flac files is better for archiving because it's lossless. If opus for some reason disappears, i'll have a lossy format and would have convert to another one losing more quality.

      How do you deal with music?

      Hi there,

      I'm considering purchasing a used Galaxy S7 and moving to LineageOS and would like to hear about similiar experiences. I currently own a iPhone 5S (only my second smartphone). I plan to continue using Ting as my provider.

      I am attracted to LineageOS because it's open source and allows greater control than the standard Android-build I'd get from an ISP. I'm not afraid of installing ROMs or tinkering - I know I'll be doing a lot more of that by moving to an open-source OS.

      I was looking at Galaxy S7 because it's well-known and has wide support/information available on forums, etc and of course because it's relatively cheap to get a used one ($200-ish).

      I'm in the US and use Ting as my provider.

      So some questions I have are:

      • Should I expect to use the standard Google Play store? I'm still a little unclear on this after looking at the LineageOS website and wiki. The best I could find for an answer is this article talking about installing default google apps. I think my question is so basic it's not addressed on their site lol.
      • Can I drag and drop MP3s from my computer to the phone? In other words, can I get my music on there without having to install something dreadful like iTunes or use Spotify/Amazon Music?
      • The LineageOS project looks healthy to my untrained eye...any rumors that it'll vanish overnight?
      • I found these instructions for a Galaxy S7 Anything else I should know or look out for?
      • Any general thoughts/advice about moving from the Apple to the Google ecosystem? I'm entrenched in Google everywhere BUT my iPhone where I mostly use Google apps.
      • What else should I look out for? See any gaps in my understanding?

      But I wouldn't have noticed it otherwise if I hadn't been cleaning my desk that day. It's placed on the far side of my desk on a laptop stand (although well ventilated) so I rarely pay attention to it, if at all. It might have gone on for much longer and eventually led to a disaster before I even caught on to the problem.

      So, my question is: how does one track these potential hardware problems without having to manually inspect different parts of the device every now and then?

      (While my device is a laptop with W10 OS, the question isn't limited to just that. Inputs for Mac and other related products are also welcomed.)
