Team one discussed deploying an Apache Kafka cluster on AWS to handle data processing. A light blog that didn't really add much to the understanding of what's actually going on. They've since published a final blog[^] that summarises what they accomplished. What it comes to is an application that shows a map with other drivers in the vicinity. The key feature is a "driver score" that alerts the user to the crazy factor of other drivers. Lots of dramatic music.
Frankly: I don't get it. The entire project could have - and frankly should have - been a simple smartphone application. Smartphones have GPS, accelerometers, data connections and standards libraries, APIs and massive programming support. The inclusion of an arduino unit and Dell Wyse was not adequately explained.
What I would have liked to see: a smartphone app to handle the communication and UI. The arduino connected directly to the OBD port of the car to get driving dynamics, which would then communication with the phone via bluetooth. At least a sketch of what it would take to have the application ultimately apply the brakes in case of an impending accident. What we saw was basically Waze without driving directions.
Team 2: DIY Smarthomes for Aging-in-Place
We're at the point where the teams are mow pulling it all together and Team 2 have given us a rundown of how their system would work. This is split between nicely technical disucssions on using Clojure on the Edison (thank you guys!) and general comments about coordinating wearable and sensor data through a local gateway. To me this seems like they are simply creating another HomeKit or Brillo. The addition of Edison based bridges to route bluetooth sensor data to the main gateway is an excellent idea. However, I'm still looking for the meat. Where's the backend services and algorithms that will take this data and, using machine learning, translate this into real-time Alerts of Impending Doom?
Ultimately Team 2 did not achieve their goals. What they did achieve is a great contribution to the developer community in their form of their work on Iotivity. However, this again underlines the issues with IoT: there are no standards. We're still fighting the tools.
Team 3: Cognitive Healthcare System for Rural Areas
Team 3 has also wrapped up their project and demonstrated their remote patient diagnostic application. It's basic - 4 lead ECG instead of 12 lead, a slightly questionable body temperature probe placement (probably to keep it kid-friendly) and nothing adventurous such as blood work included. It is a prototype, after all. Someone may need to see a doctor, though, because blood pressure of 102/85 is a little low.
The sensors are all controlled and their data collected by the main application. Communication is via WiFi, and data is then processed manually (lots of Python scripts) to detect anomalies. Two main thinks are apparent
The data acquisition is way too coarse. A cardiologist could never read an ECG of that form. ECGs are subtle and require a hell of a lot of training to read. Machine learning can certainly do the job, but only if the data is very, very good. They need to use some decent screen casting software. It was very hard to see what was happening on the screen in the demos.Overall the ssytem seems reaonably complete. The risk of mis-diagnosis is extremely high with their current setup but it's about the concept, not the actual data and hardware at this point. Again, I probably would have considered a smartphone app more appropriate given that power and WiFi in remote communities may be harder to come by than a simple cell tower. WiFi, bluetooth and a ton of processing power is in your hand.
Team 4 - Proximity carts
Team 4 have gone all out in the video[^] department with a fully animated video explaining their system. Unfortunately their video showed a slightly cumbersome UI turning on and turning off LEDs. I have no idea how this relates to. Frankly I'm lost
Team 5 - remote agriculture health sensing
Team 5 have been granted an extension due to shopping dalays. Before that they had a couple of posts about using Matlab for porcessing and the BeetleBot (sans laser beams, unfortunately). At this point there's no final solution that's been demoed. Hopefully by this time next week.
Security wasn't addressed
These challenges are meant to stretch the imagination and coding skills while showcasing the technology available. The Intel IoT kits are maturing rapidly and the availability of APIs, SDKs and toolkits is astounding. There's still lots and lots of work to do, though, and frankly fewer, more comprehensive options would help the community rather than more. I'm sad to see not a single .NET entry.
What was also not mentioned, apart from a brief note by Team 3, was security.Is data from sensors being encrypted or passed through secure channels? Are data files with personal data (health monitoring data, car sensor dara, home sensor data) being stored in plain text or encrypted? What scope is their for the data between sensors and the processing system to be hijacked? Could the accident prevention system be hijacked from within the car easily? What about another driver hijacking the signals from surrounding cars? Given that the remote health app was on a laptop, could personal health data be accessed by other apps on that laptop? Were remote webservices protected with authentication? Was all communication handled over SSL?
I saw a lot of time spent fighting tools. I saw essentially zero time spent protecting systems (and people) from harm.
In my mind the IoT challenge isn't the software or hardware. It's the data. Specifically, it's protecting the data.
Team 1 (inter-car communication) have given us an architecture diagram. It doesn't say a lot - except they are using AWS for hosting with Spark and ElasticSearch. There's "Data Processing" but on what we're not told.
My experience with AWS is mixed, but given this is a prototype then it's a sensible decision. As long as they keep tabs on costs. At this point they have a basic server running and can pub/sub to those servers.
Team 2 (Aging in Place) have a Clojure nRepl server running on their IoT devices. This is way cool. repl = read-eval-print loop. You type in a command, the server reads, evaluates and prints out a response leaving you with a blinking cursor waiting for the next command. We've all used one. The "n" means networked, so you have the server on one machine and you use a client to send the commands from a different machine. What this means is they can explore the device APIs using a simple command line without needing to go through a code-compile-deploy-execute cycle that would be needed if using, say, C.
Team 2 then has an excellent discussion on designing UIs for the elderly, and how best to (semi) automate systems. The only issue I have is that their project was meant to be more about looking at behavioural patterns of those in their twilight years to look for correlations between behaviour and undesirable incidents. The goal is to predict problems based on behaviour, not to necessarily reduce the set of behaviours in order to reduce the risk set. That's cheating.
Team 3 (Healthcare for Rural Areas) have managed to connect sensors to their gateway via Bluetooth. In this case a heartrate monitor. Someone's been putting the work in if that screengrab of a 43bpm heartrate is accurate! They then present a great summary of the heart's electrical system and ECGs. Excellent stuff, especially for those who have a fear of ST-elevation in their future (coughs nervously) but it's a bit of rabit hole. ECGs are very powerful. As is a simple matter of asking the patient how they feel or where it hurts.
Regardless, the team is embarking on a a project to use a biologically inspired machine intelligence technique to learn and read ECGs. Another rabbit hole discussion (addictive though) on the brain. I'd defeinitely recommend On Intelligence for more in this vein.
I'm not sure where this is going. Health is way more than an ECG.
Team 4 (Smartcart) seem stuck trying to design proximity detection using RSSI levels of each unique identifier of items on a shelf.
They then upgraded the firmware of their Arduino using flawed and missing documentation, arcane button timings and presumably lots of swearing. Lots of things broke.
This just doesn't make it fun for anyone. Systems need to be more robust than this. My heart goes out to you, guys.
Team 5 (FamrConnect) discusses the sensors they'll be using. Temp, light, sound. Also LEDs that could potentally be used to attract (and destroy) bugs. Friggin' laser beams? A sensor-laden remote controlled bug could be used send around a crp to gather data. I still think a drone would be better, but a bug would be better than nothing. A bug with friggin' laser beams even better.
Hi Chris Maunder, This is Bharathiraja Nallathambi from team Agro Hackers, Thank you for your suggestions for using bug with laser beam or drone, which will be the ideal option. We agree on that. We are trying to make use of the provided electronic components as much as possible, while maintaining the cost factor as low as possible. We will make sure that, we will take your suggestions and provide provisions in the framework for drone and bug with laser beam.
Thanks and Regards,
Team 1 have gone an interesting direction and are looking at including an alcohol sensor in their solution. To me this is a good idea in theory, but won't work in practice.
it's a little Big Brother. I don't want to send my breathe alcohol (and it's breath, not blood) settings to an unknown company.
It's inaccurate unless it's setup properly (ie user has to blow for a proscribed period into a tube). Otherwise it could pick up alcohol from passengers
it misses the point. The point being that distracted driving now kills more than drunk driving, and fatigue is right up there too. Instead of a seemingly easy solution that's doomed to fail, why not get smart and add some driver heuristics that will detect not only drunk, but distracted, fatigued, and drivers under the influence of drugs. Steering variability, braking patterns, speed. Things that trigger alarms.
Team 1 also made the statement that they only need short distance (100m). However, they may need to consider that two cars each doing 120kmh-1 will close a 100m gap in 1.5 seconds. If there's an emergency situation that needs action then, given mass and momentum, 1.5 seconds isn't going to buy you anything.
100m just isn't going to cut it I'm afraid - not for highway speeds at least.
As an aside: I love code samples. I love, even more, comments in code samples that explain what's happening.
Team 2 have some tangible goodness for those working with Curie: "Zephyr is destined to be the operating system of choice for the forthcoming Curie SDK...The only problem is that the documentation on the Zephyr project website is outdated and inconsistent". So they put together a guide to Zephyrizing the Curie. Awesome guys.
As a further aside Team 2 have posted a comment on the fundamental issue in IoT: Security. I am really, really hoping Team 1 focus on this, given that they are writing in C and are trying to control 2 tons of speeding death. Team 2 is building their stuff from the ground up to ensure things are secure. Read this and be worried.
The golden rule is to not try and build your own security. The fact that Team 2 needs to speaks volumes.
As another aside: if you've ever wondered how you write a system that will integrate multiple devices (some using Bluetooth, for instance) then follow their work on Iotivity. It's fascinating, and their discussion on basic Iotivity “Servlet” processing is brilliant.
Team 3 are continuing their work with MQTT to act as their pub/sub framework. Some good, commented code samples. As I said: I love a good code sample.
Team 4 are fighting boards and sensors and APIs. And Zephyr. However, they've settled on using Apache Mynewt as their OS for their bluetooth smartcart system. It's all there, including a handy Docker container to get them going.
...and finally Team 5. Team 5 are getting down and dirty with the Arduino IDE on Linux with a handy step-by-step guide to getting you started. They then have to deal with some machanics: FFmpeg for getting their crop images to their gateway
One thing I was thinking about Team 5's efforts: they are reliant on fixed camara installations to detect crop issues. I'm fairly certain crop issues aren't going to conveniently pose in front of the limited number of fixed cameras, so why not make the cameras mobile? A fairly straightforward app to control a drone that would fly a course and take representative shots of a crop (flying on when the weather service says the conditions are OK) would require less hardware and provide greater coverage. And be way more cool.
Frankly I am concerned that IoT, as pushed by some pundits, is missing the point. We've had connected devices forever. The differences now are
the devices are super cheap and there are tons of consumer-ready versions
They are connected to via internet gateways for (potentially) all to see
we're now using them to lock our houses, control our webcams and furnaces, and collect our biometric data
So can I suggest that we step back a little and give equal focus to security and privacy. It's important.
Over the course of eight weeks, five teams will develop, prototype and journal their progress using the Intel® commercial IoT developer Kit
Team 5[^] has given us some more info on how they are approaching their goal of remote disease identification. It's a basic, common-sense approach: Have a bunch of cameras trained on a crop to monitor and identify diseased foliage in real time. If anything is found then the farm will be sent information on how to deal with the issue. If anything new is found then the images will be catalogued, identified and added to the library.
They have my attention with their use of machine learning to classify crop states using a well defined set of signals. Artificial intelligence and machine learning are, by far, the hot topics this year and it's nice to see it be used for soemthing other than driving cars and predicting stock prices. Priorities, anyone?
Team 4[^] have up'd the hardware count for their proximity based advertising system. They did get down and dirty with a bit of code in their blog, but even talking dirty like that isn't going to sway me. An interesting point they've raised is that managing a messaging system via proximity is going to require very, very careful tuning of the signal. Once a beacon is out of range the recievers will need to know this. No point getting a message about a can of tomatoes 3 aisles over.
But what about a message from a box of cornflakes on the other side of the shelf? I'd be interested in seeing how they handle that one.
Given that bandwidth (and phone batteries) are a limited resource they are focussing on a light messaging protocol via MQTT (Message Queuing Telemetry Transport). This is a lightweight M2M protocol specifically for IoT.
Team 2[^] has explained how easy it is to get Clojure running then shows precisely the opposite. This is 2016. This stuff should Just Work by now.Anyway, using nrepl means they can develop on their desktop while evaluating code on the target device.In any case they got that bit working and then moved on to porting IoTivity[^] to the platforms of choice. IoTivity enables device to device communication.
Team 1[^] is coming to grips with the reality of ad-hoc networks of devices travelling at 100kmh, not all in the same direction. They are trying to put together a system whereby vehicles will coordinate among themselves in order to not crash. A MongoDB style master-slace system just isn't going to cut it. My thought: An every-man-for-himself system based on every vehicle looking to avoid every other vehicle by "watching" what every other vehicle is doing. Basically what humans do: We focus on not hitting anything else and we watch (and anticipate) what others are doing to predict speed and location and not be there at the same time.
Vehicles can transmit velocity (speed and direction), acceleration, mass, yaw, available traction, general vehicle health and intended path constantly. Communication will need to be super-fast, but if everyone is saying basically "I'm headed that way and here's how fast I'd be able to stop" then everyone can keep out of everyone else's way.
I'm already sensing a pattern here. There are no standards for IoT. In anything. Each team is using a different stack, different protocols, different platforms. They are all, for the most part, using the same Arduino boards and Grove Starter Kit[^], yet there's no "standard" being followed. Add to that the plethora of backend webservices at their disposal, and then open it up to even more hardware and you have a problem if you're looking for the "right" way to do things.
Maybe Javscript will turn out to be IoT's BASIC. Maybe technology will continue to progress so rapidly that new standards simply aren't necessary and current (server) based technologies will transfer wholesale to embedded devices.
Intel has launched a new Ultimate Coder Challenge[^] that follows the same structure as previous years: multiple teams, 8 weeks, 1 challenge.
This year's challenge is IoT: Who will create the next great commercial solution? Using the Intel commercial IoT development kit the challenges must come up with an idea - and an implementation - that truly defines what IoT is and means to us all.
Out of the gate I will admit I'm already heavily biased to an idea I've been spouting to all and sundry for years: a local wireless network for cars that would reduce to near zero the chance of collisions.
Team one[^] aka Team Whirlwind are working with Intel Edison and Dell Wyse[^] to create a highly distributed adhoc network modelled after MongoDBs Master-Slave model.
They will need to overcome issues such as network latency, basic network issues, interference, speed, and ultimately interfacing with a car so that the system actually does something. I hope they succeed. It's about time we had this.
Team Two[^], aka Team Geras, has the goal of diving deep into the behavioural patterns of those in their twilight years to look for correlations between behaviour and undesirable incidents. Does a hot day and a bout of lawn bowls result in more falls? Does high humidity and certain social interactions result in a case of the vapours?
This is a lofty goal and I worry that gathering and analysing enough data within the time of the contest will be difficult.
Code will be written in ClojureScript running on JerryScript. Because they want to. I write way too much Javscript (badly) and I swear we're all going to look back on the twenty-tweens and think "what sort of drunken haze were we in to think Javscript was a good idea for everything?"
Team Three[^], aka Team Iot Vaidya, are looking to create a standalone solution meant specifically for people living in remote places where there is shortage of doctors. The idea is that there's a dearth of medical support in many rural communities so why not automate some of the more pedestrian tests that can be done to get an initial good/bad diagnosis? Team Three will focus on a person’s ECG and pulse rate plus other vitals like temperature, Galvanic Skin Response. "A lot can be said by proper analysis of these parameters."
As a bit of a chronic cyclist this sort of stuff is right up my alley. I ride with my eyes glued on my heartrate, left/right pedal stroke balance, power output, cadence, calories burned and occasionally oxygen saturation and heomoglobin recruitment. Sometimes I even watch where I'm going. Having access to a wearable that would include things such as ECG, temp and galvanic skin response would be brilliant. Selfish, in that it's all about my cycling and not about saving lives (directly) but the applications for a solution such as Team Three is proposing go far and wide.
Team four[^], or Team Proximarket, have waxed lyrical about the physical web but their introduction scares me a little. Smartcart is a proximity based technology for retailers that, among other things, will reduce the impact of customer oversight. Oversight meaning "Excuse me: it looks like you forgot to pick up toilet paper. It's in aisle 3, 7.5m to your left." or "Escuse me: it looks like you're trying to leave the store without spending enough. We've talked to your car's infotainment system and it agrees you're not going anywhere until that shopping cart is nice and full"
If they win then I'll be the first to welcome our new robot overloads.
But again maybe not. Team Agro Hacker is working to deliver a solution to crop disease and pest management using image processing and machine learning. You get the computer to take a peek at the leaves of a crop and have a good hard think about what could be wrong.
Admirable work, and increasingly important in a world rapidly growing. They have no, however, made it clear how this is an IoT solution. They'll need to clarify this to move ahead.
We've had a number of complaints that a member will spend a great deal of time crafting a response to a question in Quick Answers[^] only to hit the post button and find the question was deleted or closed while they were answering it.
In a perfect world everyone would agree on what's suitable for answering and what's suitable for closing, but our world is far from perfect. Effective today we've added a feature that will re-open a question that's been closed if someone posts an answer to that question.
We could have implemented question locks, but locks are messy.
We've launched a small change to Quick Answers[^]. When posting a question you get the usual "Subject" and "describe the problem" boxes, but we've also added a "What have you tried?" box that must be filled in before you can post your question.
It makes it harder to post a question (barely) by forcing the poster to think a little about what they've done so far. It allows those answering to avoid things already tried and suggest new ideas. It will also, possibly, act as a self-identifier of those too lazy to explain their problem to those eager to help.
Thanks Chris, Its really good move. It helps questions to become more self-explanatory and avoid same solution that already tried by OP, Additionally it avoid spam post and lazy questions. Most of the time in CP, I have seen questions with title "Please solve it urgently" or "error in c# application" with same description as title. (though I tried to "IMPROVE" it but due to less description, it remains unclear)
Members should take its benefits and can improve the question quality to help them resolve quickly.
Finally "More time to explain question will help to reduce time to resolve it"
As far as the links are concerned (copy/pasting the link). I would recommend, instead of sending a request to get the title. You should leave that to server when poster is done editing the post to update the content of that link to a title (if from CodeProject). Like Markdown! It would make it a lot better. Plus, it would give you an opportunity to add link titles for posts from other sites by reading their <title> tag.
For example, just to edit this messages for you, I have sent like 15 requests with 1kb+ size. For me, it doesn't matter, but for someone with a metered connection, it does. This size also increases with the increase of characters. (Right now it is 2.3kb and growing for each request).
The sh*t I complain about
It's like there ain't a cloud in the sky and it's raining out - Eminem
~! Firewall !~
The reason we do Ajax calls for formatting is because we want to ensure the colourisation is done properly. We could simply skip the formatting, or use something like syntaxhighlighter to do some rough colourising. It's been discussed many times.
If you're worried about postback size then uncheck the "Show a live message preview as you type (not available < IE9)" checkbox in your Settings[^] (under the Forums tab)
With regret we've abandoned using CommonMark to render our messages.
CommonMark is meant to fix the issues inherent in other Markdown implementations while being true to the core ideas of Markdown. Basically: it should just work, there should be no surprises, and it should work with existing HTML. Markdown / CommonMark handles the main gruntwork of text formatting and when you need some fine tuning just throw in some HTML and you're good to go.
Unfortunately CommonMark handles PRE (i.e. Preformatted) blocks in a manner that simply doesn't work for us. A PRE block should (at least in my book) allow you to enter text and have the formating maintained as-is. On CodeProject we cheat a little[^] and allow things like B, EM and U tags for those who want to highlight sections of code, but beyond that what is entered is what appears.
In CommonMark a PRE block that contains text that is indented 4 spaces will trigger the creation of a <pre><code> pair that wraps the indented block as if it were a code sample. Code samples are often are indented, so whenever you paste code into a PRE block then you'll more than likely get nested PRE blocks.
This just doesn't work for us. We love what CommonMark is doing to provide consistency, but that's just seems an odd decision. For now we're disabling Markdown in Quick Answers and reverting back to MarkdownSharp.
This makes me sad.
We announced the introduction of Markdown[^] into the forums and Quick Answers a while ago, but we were never truly happy with the implementation of the Markdown processor in use. Ambiguities, lack of standards, and poor performance of the Markdown transformer were niggling annoyances.
The syntax is slightly different[^] to that of Markdown, but the changes are small enough that it should, hopefully, not cause any problems. As always if you do come across issues let me know and we'll season to taste.
We now support Gravatars for your profile picture to help reduce the pain in maintaining your latest profile selfie (or professional studio shot - whichever). Just setup (or update) your Gravatar pic and then on your settings page select "Use my Gravatar", hit update, and you're done.
We'll add it to Quick Answers soon, too, but for now here's a refreshed on Markdown:
We use GitHub flavoured Markdown with a couple of minor changes. Here's the gist:
Heading (or use #Heading)
And a Sub-heading (or use ##Sub-Heading
#### Use #, ##, ###, ####, ##### for H1 - H5 headings
Paragraphs are separated by a blank line.
A single newline will not cause a line break.
Leave 2 spaces at the end of a line to force a
Text attributes *italic*, **bold**, ``code``, --strikethrough-- are supported, as is <font color=red>HTML</font>.
// To insert code, use ``` before the code and then end with a closing ```.
int length = new string("A string").Length;
Hyperlinks are easy: [link to CodeProject](http://www.codeproject.com).
- pears and stuff

And a Sub-heading (or use ##Sub-Heading
Use #, ##, ###, ####, ##### for H1 - H5 headings

Text attributes italic, bold, code, strikethrough are supported, as is HTML.

I've loved Ace[^] forever. It's one of those pieces of code which, when I first saw it in action, I couldn't even begin to think how they managed to do it in a manner that didn't bring the entire browser to its knees. But it works and it works very, very well.
I'm happy to announce that after a cold, lazy evening, a few Google searches, some beer[^] and a bit of swearing I've added Ace as the Source editor to our online WYSIWYG editor for articles.
Editing articles is meant to be a WYSIWYG affair but it's never the case with HTML. Us control freaks always want to dig into the markup and make it just right. With Ace we now have that markup syntax colourised which helps enormously when your article's getting a little long. On top of that we get line numbers, tag matching, and real-time validation.
Of course, if it's just not working for you there's an "ace" button next to the "Source" button that allows you to deactivate Ace if it's causing problems.
Our article voting system has evolved progressively. From one person, one vote to a weighted system, to requiring comments when down-voting, to a system that statistically removed junk votes, and then lately to a system that recognised that voting patterns are not only bell curves, but sometimes, legitimately, bimodal.
We have, to a large degree, been successful at suppressing malicious down-voting. Too successful, it seems, and the article voting system is now massively weighted towards up-votes rather than down-votes. To up-vote you merely click the 4 or 5 rating. To down-vote you need to add a comment, and if your down-vote doesn't agree with the majority then your vote may not be counted until a sufficient number of other members have likewise voted the article down.
So while up-voting is great in that it rewards authors and gives readers a way to say thanks, up-votes are bad when the up-votes are not votes based on the technical merit of an article but instead based on being the author's friend, family or colleague. Make it 50 friends, family members or colleagues and the vote for a given article is hopelessly invalid.
Basically: you can have too much of a good thing. It's easy to up-vote, hard to down-vote, and so the average article rating goes up and the ability to sort the wheat from the chaff goes down.
Starting today we're removing a barrier on down-voting. You are no longer forced to provide a comment when down-voting. We have our historical-based expectations on what will happen but will be monitoring the results closely just in case.
The change is effective as of now. As always we're open to suggestions and ideas to make it even better.
We have an occasional issue whereby an author will get their friends, family, colleagues, and random people off the street to vote for their article. Our voting system[^] is geared towards handling a case where lots of people say "this is great" and a few downvoters say "boo, it's crap" by filtering out the outliers on the assumption that the group vote rules.
However, when you have 50 low rep voters saying "it's a 5" and 5 high rep voters saying "this is terrible (or dangerous)" then we need to adjust. The change we've made is that if a certain number of high rep members vote a certain way then no votes of that given score will be filtered out. The naysayers will be allowed to nay-say and balance will be restored.
We are now checking every forum message for spam, and every message that even hints at being spam will be moved to a moderation queue. We won't nuke the message: we leave that dirty work to the top-rep members and protectors. Once the message is approved then it gets posted as a regular message. Those messages that are moderated by a member as being spam will never see the light of day.
We hope this helps with the current challenges, and we'll be extending this to Quick Answers and the Article system as soon as this beta test is complete.
We've had Google, Facebook and LinkedIn login for a while but we're happy to announce that you can now login to CodeProject using your Windows Live ID. Just click the Windows icon at the bottom of the signin dropdown (top right of each page) or the Windows logo on the sign up / sign in page.
We are continuing to enhance releasing api.codeproject.com, our API service for those looking to harness the data and services of CodeProject. Please dive in, check the docs and the samples, and get back to us with any issues or suggestions.
As part of this we're deprecating APIs that haven't been used for years. The specific APIs removed in today's update will be:
Our explorations and experiments with CodeProject are never ending and it’s with a certain sadness that we’re retiring Workspaces and CodeProject.TV.
The creation of new workspaces will no longer be possible from tomorrow, and Workspaces itself will close August 30. Your current Workspaces will be fully functioning until the close of Workspaces.
Workspaces was a framework designed to allow multiple applications to co-exist under the same roof. We started with a Git server (::GitMachine) and a Task management system (::Tasks), then added ::Docs for documentation. The beauty of the system was that since it was designed around APIs it was trivial to have it integrate with CodeProject.com, and trivial to have other applications integrate with Workspaces in turn. Each workspace would allow any number of any of the currently supported applications to be “hosted” within, so you can mix and match and build your workspace system to your liking.
CodeProject.TV was our foray into bite-sized, cost-of-a-coffee video tutorials. Members could create their tutorial, upload it and set their own price. We’d handle the transcoding, hosting, serving, backups, credit card processing and publisher payments, and free videos were just as welcome as pay-per-videos. A simple solution to a number of requests from our users.
We love both, but as we do each year we looked deep in our hearts at what we felt was best for our members and readers and decided that we’d better serve everyone by focusing our resources, and our attention, on CodeProject.com. This means a focus on our members, our articles, and our community. We’ll move our finger down to our next "what if…" item on our endless list of ideas and see where that takes us.
For those who purchased videos or workspaces we’ll be offering a full refund. Even if you tried workspaces for a month and then cancelled your subscription, even if you purchased and watched and downloaded a video we’ll refund your payment.
For those who have files in ::GitMachine or tasks in ::Tasks, we’ll be keeping these two applications running until Aug 30 but effective today no new workspaces can be created. All items in ::Tasks can be easily exported to Excel spreadsheets, and obviously all Git repositories can be cloned to other Git repos.
I kind of expected this with TV. Initially I liked the idea but then found it difficult for me to focus on few minutes of videos to get to some idea/solution compared to an article (with some copy-able code in it ). As you mentioned, onto next idea(s)
A retrospective on TV as well as Workspace would be helpful for future projects.
Maybe it's a generational thing, but I find it difficult to learn by video. I've done a few MVA courses, and while the content is solid, I feel I could learn 2 hours of video in 15 minute of reading, and retain more.
I see YouTube being used for all kinds of lessons and for the most part it doesn't work for me. The exception is very hands-on things like guitar lessons.
Maybe, video might be useful for more complex items or difficult to understand topics. async/await was confusing for me, and it was helpful for me to view few videos with the code samples downloadable at a different URL.
