derwildemomo··on Things I've learned in my 10 years as an engineering manager
I was wondering about that for a while now - it feels in my last few jobs as an EM, the major part of my work (or rather the most influential one?) was managing, coaching and guiding product. The realization was actually quite simple for me: while hiring in engineering is defined by an sometimes absurd number of interviews, code challenges and so on, product is a case study and you're good: and that doesn't seem to be doing the trick.
derwildemomo··on Ask HN: What Are You Working On? (October 2024)
Building Split Flap Displays. Started 18 months ago and kept me on a super interesting learning path. First shot was using open source designs (https://github.com/scottbez1/splitflap), but then kept building more and more parts myself. Coming from a software engineering background, getting into designing mechanical things – and then more importantly the electronics around it - has been really challenging, but also very rewarding. At this point I have my own screen printed flaps, custom PCB Design and a, what I consider, really smart protocol that allows me to daisy chain a basically arbitrary number of display elements. It's fun!
derwildemomo··on Gron: Make JSON greppable
Great idea, definitely makes sense when you have that kind of problem.

Also the username of the author made me chuckle, bonus points for that.

derwildemomo··on Markovkeyboard: Keyboard layout that changes by Markov frequency
phew.. I think that someone might have been me, if you're talking about qwerted? https://vimeo.com/8716996
derwildemomo··on Charles Proxy now available on iOS
Came here to say the same thing: If you're interested in seeing the traffic caused by your own app (and also making that info accessible to other stakeholders during dev time), netfox is the way to go. Super easy to integrate and provides usually enough info. Also no tinkering with the system settings or third party apps required.
derwildemomo··on Binpod: Precompiled Binaries for CocoaPods
So, this is something i've been working on for a while now. What it does is enable you to use cocoapods to integrate prebuilt frameworks for any pod. binpod does this by recompiling pods into a .framework and republishing that pod to its own spec repository. All you need to do is to add a line to your Podfile and you're got to go.
derwildemomo··on How to never complete anything
Just my two cents, but I just looked at http://everydaycheck.com and I think it's both a great idea and (from what I can judge) well executed.

Also one piece of advice: Do Shown HNs more often. For me, they are regularly an great source for feedback.

derwildemomo··on Show HN: Frop.io, instant remote presentations. In your Browser
Sessions are ephemeral – once you close the tab or browser window, the session is gone (and the viewer will go back to the 'waiting for content' screen). This is by design – frop is meant for realtime collaboration or presentations, so having something stick around forever is not really the use case (in my head).
derwildemomo··on Show HN: Frop.io, instant remote presentations. In your Browser
At the moment it's one viewer per presentation, though that limit is quite arbitrary and could be changed in the future.

I thought or considered this to be a nice-to-have but not mandatory feature, but more people keep asking for that. Always good to have some external feedback – thank you!

I like the gradient/Color-Mode Idea very much. Going to integrate that (with attribution if you don't mind).

Do you have any example regarding the Visualizations? I'm keen to learn more about that and to see if it fits in well.

Hi, thank you for your feedback!

You are right, the current feedback mechanics need some love. I'm working on that ;)

Supporting Word, Excel, PPT is also an item on the list, but since we rely on client-only processing, displaying documents consistently across platforms and browsers needs some time and work. But: On it!

Thank you!

Not really, I think there are better and more mature tools for doing that (like appear.in or Skype) out there. frop.io is quite special in that it does not do screensharing at all, but just transmits the content, being super bandwidth-conserving.

Ha, I'd actually love that. Google Slides should be in the realm of possible things, PPTX could get more complicated.

What I suggest you try is to upload a PDF. I've built a moderator mode on the presenting screen, there you can do exactly what you want (just not with a PPT but with a PDF-Presentation).

The reason is that PDF can be rendered very consistently across platforms, this is more problematic with Powerpoint and friends.

derwildemomo··on Show HN: Frop.io, instant remote presentations. In your Browser
Hi HN!

https://frop.io is a simple application that allows you to present content (PDF presentations, Images, Text, YouTube videos) on a remote screen without installing any software. It's completely based on web standards (Websockets, JS) and runs in most modern browsers.

Simply start a session by calling frop.io/[yoursessionname]

I posted this two weeks ago. Since then I've completely overhauled the design and built a native tvOS and Fire TV viewer app (both free and publicly available).

Once again, looking forward to your comments, suggestions and criticism.

Thanks!

derwildemomo··on Show HN: Frop.io – painless remote presentations
Hi, thanks for trying frop.io and the great feedback!

I'm a bit reluctant into integrating anything that would require WebRTC (screensharing, video, audio) since I feel there a far superior products out there (like appear.in, TeamViewer or Skype).

Regarding private/secure presentations, End-to-End Encryption is in the making and you can already use any URL you want for the session.. like frop.io/operon.

derwildemomo··on Show HN: GitPlex – A new Git repo management server with code review
This is something I've been thinking about quite a lot lately – I considered extending our git-flow a bit to contain review branches (or something comparable). If you'd like to chat a bit about potential solutions for your approach just drop me a line!
derwildemomo··on Show HN: Generate Google Slides from Markdown
Along those lines there's also Deckset [0], which is focused on turning "boring" markdown notes to visually appealing presentations. I've used it once or twice and really like the idea. It's only available for Mac (afaik) though..

derwildemomo··on Ask HN: Is Xamarin worth learning?
Hm, completely different experience here. I've been involved with three rather large Xamarin-Projects in the last year, and we were (team-wide) completely surprised at how much of the code can actually be shared, how our velocity compared to native development and the overall dev experience.

I think the code sharing thing really comes down to how you're using Xamarin – if you keep on writing apps the way you're used to from the original platforms, there's not much to gain. On the other hand adopting the patterns and ideas that influence the .NET sphere (DI/IoC, MVVM..), Code Sharing rates (or PCL vs. Native LoC) can be as high as 80/20.

Xamarin Studio certainly has its own shortcomings, but both Microsoft (Visual Studio for Mac) and Jetbrains (Project Rider) are actively improving or developing alternatives, so I think that pain is going to fade over time.

derwildemomo··on Leaflet 1.0 – A JavaScript library for mobile-friendly interactive maps
Just recently I had to choose between Google's map offerings and Leaflet.

Performance wise, Leaflet is an order of magnitude faster when it comes to frequent bounds/location updates, speaking for itself. Great work!

derwildemomo··on Ask HN: How do you use Amazon Echo?
German Echo user here.. I googled a bit a while ago and found a perfect solution for the timezone-thing. It turns out that you can (via some request tinkering) set the timezone to whatever you want, instructions here:

edit: typo.

derwildemomo··on SoundCloud could be forced to close after $44m losses
german here. a net income of 40k will put you somewhere in the top 20% of german households [1], . berlin is generally a really cheap city (see this [2] article from 2014.. cost of living/rents below german average), so saying "that's enough for owning a bicycle" is just not true.

derwildemomo··on Finding iOS Memory Leaks with Xcode's Instruments
> 7 simple and not really documented steps of finding memory leaks using XCode

There's actually event a "Leaks" template in the instruments app, I wondered why the author didn't use that. And that tool is even documented by apple, see

derwildemomo··on Show HN: Character Recognition with OpenCV
It's perfect from an OCR point of view: - Perfectly upright, no visible rotation - Sharp, not remotely blurry - No visible brightness/color gradient (as is often the case with pictures taken by mobile phones.)

It contains umlauts (and i'm not sure whether the tesseract training data for german includes those, but i'm quite certain it does), but that doesnt disqualify the image.

I was just saying hey, it's not using openCV but tesseract, so the title is wrong.. and i stand by that statement. I appreciate the work you do and i was exclusively referring to the title here. have a good day ;)

derwildemomo··on Show HN: Character Recognition with OpenCV
The title is wrong – it actually uses Tesseract to do the OCR.

Call me negative, but I don't see the big leap here, it's just a simple demo to recognize text in an almost perfect input picture. It uses the Emgu CV, self description: "Emgu CV is a cross platform .Net wrapper to the OpenCV image processing library.".

derwildemomo··on How to submit an app to Apple’s App Store when it uses encryption
You are off topic.
derwildemomo··on Reports that Bassel Khartabil has been sentenced to death
Hey, no one is without powers. Ours are very limited in situations like that, but amnesty international usually provides a set of honoraries that can be addressed in situations like that, as well as in depth information about the case, in this case: https://www.amnesty.org/en/documents/mde24/2603/2015/en/

Of course, writing someone is useless most of the time, but within the powers we all have is also the power to create awareness for a situation of massive injustice.

derwildemomo··on More Apple Car Thoughts: Software Culture
Haven't we like talked about this 3 hours ago ;)?
derwildemomo··on Quill – A cross browser rich text editor with an API
Thanks for the great job!

Just recently I, by some means of evil hackery, embedded quill in an Xamarin-based iOS app. Quick, painless and gets the job done 100%. (Sidenote: I proxied the Controls to a native component to make it look .. "more native".) Back to the point: Great component, awesome documentation, highly recommended.

derwildemomo··on APA Review Confirms Link Between Playing Violent Video Games and Aggression
Would be interesting to figure out whether the different methods "used for venting out" anger make any difference. I do agree that playing a game is different from punching a bag though, takes more intellectual skills and such, yet I for one remain convinced that the problem persists – whether it's punching a bag or hunting bots.
