<p>Definitely solid enough to be useful. I'm about to print my second set of RF PCB's based on the simulations with it. There are still some quirks where you have to read the manual a couple of times until the right order of commands "clicks". But there are good examples that can be followed and they seem to be expanded all the time.</p>

<p>Going into the RF field myself, I've been troubled with the license costs of tools like HFSS and CST. After a brief test of the open source tool OpenEMS I've landed firmly on the newer open source tool EMerge (<a href="https://github.com/FennisRobert/EMerge" rel="nofollow">https://github.com/FennisRobert/EMerge</a>). It's a little rough around the edges still as it was released in the fall. But I've already gotten good results from it designing my own RF hardware.<p>Apart from that I wonder how much of the resurgence can be traced back to more active conflicts around the world? There is a booming Drone and EW development within the military sector which could be what drives it?</p>

<p>Sounds nice, and they even have the good stuff on github with an explaining how-to article on medium.<p>If you're into Digital Pathology and Whole Slide Image (WSI) analysis then there is a whole undergrowth of open source tools and projects to dive into. I especially like QuPath by Pete Bankhead (<a href="https://qupath.github.io/" rel="nofollow">https://qupath.github.io/</a>). It has a more accessible interface than python (as in the article), it supports various machine learning algorithms and also has some nice video tutorials (<a href="https://www.youtube.com/channel/UCk5fn7cjMZFsQKKdy-YWOFQ" rel="nofollow">https://www.youtube.com/channel/UCk5fn7cjMZFsQKKdy-YWOFQ</a>).</p>

<p>Oh, memories. We also made a lightweight channel service to take the load off of Q. I think it was a little before newserv came into production. We designed it over generous amounts of whisky in a suburb to Stockholm. It's on github (<a href="https://github.com/quakenet/lightweight" rel="nofollow">https://github.com/quakenet/lightweight</a>).</p>

<p>The article and paper lacks any indication of the amount of energy needed to run such a magnetic field. What amount would it take to run it, and what sources of energy would be viable for it?</p>

<p>Thank you very much. Interesting article that ties together concepts from different fields.</p>

<p>Thank you. I think it's funny how the same idea spawns several places at once. And great to hear that you guys think there is a demand for it.</p>

<p>Thanks!<p>I thought about FB integration, but decided against as I wanted to have a transparent privacy model. In my opinion the privacy becomes somewhat opaque when FB gets involved. I'll give it a second thought though. The natural viral factor is appealing.<p>Ads are somewhat obvious. If I placed them on the comment page related to each link it might be possible to make them somewhat targetted. I hadn't thought about sponsored content, thanks. It probably ain't relevant yet though, I guess the site needs a certain size before it comes to that.</p>

<p>Somebody said "Launch early, launch often", so I guess it's about time.<p>WhatMyFriendsRead.com -- a social recommendation service for interesting links and content. Main idea: What is interesting for you is what your friends find interesting. I made a functional prototype hacked together in php+mysql with ugly html+css. But it works which is why I guess now would be a "launch early" moment. Or atleast show to a bunch of people for feedback :-)<p>On the site your main source of links is from people you add as your friends or people you subscribe to. People you subscribe to provide you with links by posting them. Friends provide you with links both by posting them but also by reading other peoples links. By reading them they recommend them to you. If you want to change the type of content you are getting then you have to change your subscriptions or friends. This way the normal karma driven paradigm is changed to a more action based paradigm. Your actions can have the effect of people subscribing or unsubscribing you.<p>I have a number of problems with my site, which I would like advice on:<p>- I have no idea how to drive traffic to my site. The site doesn't really work without having a critical mass of people using it, so I have to bootstrap content into it somehow. I also have to get people to visit it somehow. I thought about reddit's self-served ads as a cheap way to present it to users, but I'm not sure if I'd hit the target audience - whomever they might be.<p>- "Prompted by login-form". The concept only really works if users make profile on the site and invest some effort in setting it up with friends. I think it's a serious flaw that there is no readily accessible non-authed part of the site, but how do I fix it? Auto-generate a user to new visitors and link them to some default subscriptions?<p>- Lack of business plan. No idea how to break even, let alone earn money on the site.<p>Some background as to why I made it: In the fall (2010) Reddit was invaded by Digg users. Reddit.com won the Digg-Reddit "war", but in my opinion the old Reddit-userbase lost, as the site was somewhat diluted. A lot more pics on the frontpage, and less serious articles. My initial thought was to design a site that could withstand a large influx of new users without changing the experience for existing users. If the existing users mainly discussed tech news and there suddenly was a large influx of lolcat loving people then the original users should still mainly see tech news and the new people lolcats. Whatmyfriendsread.com was the result.</p>

<p>Nice little site. I like the simplicity of it. A couple of points:<p>- It is not immediately clear to me (FF3.6, Ubuntu) that it is a textarea above the Create Code button on the frontpage.<p>- Marking the code and then pasting it in Ubuntu gives me all the code on one line (both ctrl-c/ctrl-v and mark/middlebutton).<p>- The privacy model doesn't seem obvious to me when I'm on the frontpage. Is the stuff I post public, semi-public or private? If the privacy model is public a listing of the latest or most linked code snippets could be an idea.<p>- I miss a link to the frontpage when I've looked at a code snippet.</p>
