Kursen CAD med SketchUp blev riktigt lyckad

turning_gland_700De första två dagarna av höstlovet bjöd på regn och rusk när vi träffades på Thorén Innovation School vid Stadion i Stockholm.

Deltagarna hade vitt skilda bakgrunder och motiv för att lära sig CAD. Där fanns läraren som ville ta in det i teknikundervisningen, entreprenören som ville skaffa sig fler verktyg för kommande projekt, äventyraren med idéer till ett fiffigare vindroder till sin världsomseglare och egenföretagaen som brukar ta någon kurs på vinterhalvåret för att lysa upp i mörkret.

Alla lärde sig CAD. Deltagarna gick hem efter dag två med en kompetens som gör att de kan skapa det mesta av vad de ser för son inre syn och de vet vad de ska göra om det inte fungerar som de önskar. De vet hur SketchUp ”tänker” och de vet var de hittar hjälp om de kör fast. Jag har också lärt mig lite mer om CAD med SketchUp. Första gången jag undervisade om SketchUp för fem år sedan kunde jag ingenting och lärde mig tillsammans med eleverna. Nu kan jag mycket mer men jag lär mig fortfarande ett och anat genom eleverna.

Dennis som är en av mina elever kom in på tisdagseftermiddagen för att svara på frågor om SketchUp och visa hur han även jobbar i Fusion 360. Dessutom visade han ett projekt där han hjälper en entreprenör med produktutvecklingen av ett cykelställ.

Kursen fick en bra utvärdering. Det är skönt. Skillnaden mellan vuxna elever och tonåringar är inte så stor som man tror. En första tanke är att det är viktigare att ha nöjda kursdeltagare än elever men den tanken studsar tillbaks så fort jag tänkt den. Och med den insikten går jag till skolan på måndag och tar varje lektion som den första och sista på samma gång, ser eleverna som dyrt betalande kunder samtidigt som jag vill att var och en ska uppnå vad de drömmer om.

Det finns redan efterfråga på en ny kurs till våren. I den nya kursen tar vi även in TinkerCAD

Ge barnen kreativ skärmtid

I krönikan Ge barnen kvalitativ skärmtid ger Erika Hallhagen en fin beskrivning av tonårsförälderns digitala fostransmöder och många fina tips. Jag vill gärna addera några aktivitetsförslag på det digitala området som komplement till det nu så hyllade kodandet. Jag tänker på WordPress som ett sätt att göra hemsidor utan att kunna html men där man sannolikt lär sig den del CSS så småningom. Eller Unity3D dår man eventuellt kodar script till spel men framför allt lär sig ett avancerat verktyg för att göra riktiga spel. Eller Algodoo där man verkligen inte behöver koda men konstruerar de mest makalösa manicker. Eller SketchUp för att casdda och visualisera. Listan på verktyg där du utvecklar och får utlopp för din kreativitet kan göras lång.

Det är helt ok att konsumera film och spel och att fladdra runt i de sociala medierna men än mer utvecklande att ta rodret på sin digitala bildningsresa och och styra ut på den digitala oceanen.

Julefrid

Julaftonen av Carl Larsson 1904Vad är julefrid i vårt moderna samhälle? På medeltiden innebar det högre bötesbelopp för dråp.

Nu innebär det tid att träffa släkt och vänner, umgås, äta gott och tid för vila och eftertanke. Men umgängesformerna förändras. Alla samlas inte längre framför Kalle Anka på julafton. Med varsina konton på Netflix skulle vi kunna försjunka i varsin film samtidigt. Har fokus flyttats från att leka och spela sällskapsspel tillsammans till att över huvud taget hitta en film som alla vill se?
Förr åkte vi skidor och sportade. Nu tycker vi det är bra om barnen spelar på Wii för då rör de i alla fall litet på sig. När vi försöker begränsa skärmtiden blir det diskussioner och tjafs. Kanske är det lugnast att låta dem sitta vid sin skärm så det blir tyst och lugnt och jag kan slå mig ner med datorn i fåtöljen framför brasan. Den nya julefriden.

What are some strategies to encourage people to start using a new service (such as in the beginnings of Quora, Stackoverflow, etc.)?

Tips om hur man får ett Q&A-community att växa.

Answer by Archie D’Cruz:

I’ll add some specifics to the excellent big picture overview by Amin Ariana. Much of what follows is distilled from information provided by people involved with community-driven sites; some of it is from notes for a yet-to-be-launched project I am currently involved with.

Here then are eight strategies employed by sites that have gone on to become successful:

1. Seed carefully, nurture well.

The hardest thing about making a new Q&A site is not the programming—it’s the community. You need a large audience of great developers so you have the critical mass it takes to get started. Without critical mass, questions go unanswered and the site becomes a ghost town.

– Extract from a blog post by Stack Exchange co-founder Joel Spolsky in 2008

In that post, Spolsky addresses the critical part of building a community: seeding it with a great core of people. Both he (with Joel on Software) and co-founder Jeff Atwood (with Coding Horror) already had huge audiences for their own blogs—Joel on Software was then listed at #15 on Bloglines; Atwood’s Coding Horror was at #89.

They opened the beta to only a few hundred developers, but obviously chose well, because, to use Spolsky’s words, “The site lit up instantly!” Good enough to go from private beta to public launch in just five weeks.

Though Stack Exchange has built a network of 100+ individual sites since, the strategy remains the same for every new site that users propose: 200 users interested in the new site must formally commit and support the site by actively participating and contributing to it.

Quora was launched a year after Stack Exchange, and although it took longer to gain traction, the initial strategy appears to have been the same. A lot of the early seeding appears to have been done by co-founders Adam D’Angelo and Charlie Cheever along with Quora’s first employee Rebekah Cox. Then, to quote D’Angelo on Quora’s growth:

We invited our friends, and some of them invited their friends, etc.

2. Keep it focused.

Stack Overflow was launched as a place for users to ask and answer questions on programming. Nothing else. In a September 2013 post to mark five years of Stack Overflow, VP of Community Growth at StackExchange Jay Hanlon recalled that the pre-launch landing page had this comic that symbolized what the site was setting out to do:

The site, as he put it, was:

“…by programmers, for programmers, with the ultimate intent of collectively increasing the sum total of good programming knowledge in the world.”

Every new topic covered by Stack Exchange is launched as a separate site, rather than be included as part of Stack Overflow. Today, as mentioned in point #1 above, Stack Exchange owns a network of niche sites, rather than one giant Q&A site.

3. Keep it simple.

Ask questions. Write answers. That essentially is what Quora and Stack Overflow stand for. A clean interface, no attention-grabbing banner ads, ability for anyone to answer (with SO, you can even post as a guest). There are many relatively-hidden features that power users will find useful, of course, but they do not stand in the way of a new user being able to get started fairly quickly.

4. Keep the quality high.

Or in other words, learn from the mistakes of Yahoo! Answers. Poor questions, wrong or joke answers, atrocious language, spam and the high percentage of trolls who frequent Yahoo! Answers have made the site an object of ridicule. Both Quora and Stack Exchange have been good with attracting knowledgeable people who also write well, and have taken strong measures to police the sites to ensure trolls get turfed.

5. Keep it friendly.

Quora’s Real Names policy and the BNBR rule have likely gone a long way in ensuring that most of the site’s users show themselves in the best possible light. Users are less likely to indulge in attacks of the kind you see on comment boards, knowing that their real names are attached to their answers (and searchable on Google as well). There are, of course, some issues that have to do with permitting the use of Anonymous contributions and on contentious topics, but for the most part the site comes across as friendly to new users.

6. Keep it free.

The fewer barriers to entry there are, the more likely you are to have people at least trying out the site. Price is a big barrier, and neither Quora nor SO charge a fee for entry. Quora even gives new users 500 credits to play with (so they can ask specific writers questions), right from the start.

7. Add gamification.

Love it or loathe it, there is no question that gamification drives higher user participation. Call it what you will, but Badges, Credits, Reputation Points, Stars all appear to deliver the dopamine rush that keeps users engaged on an ongoing basis. Publicly available personal stats like 30-Day Views that Quora features are also a powerful driver for active user participation.

But gamification by itself is not enough, warns Stack Exchange’s Hanlon:

At best, the points, and the gamification, and the focused structure of the site did little more than encourage people to keep doing what they were already doing.

People came because they wanted to help other people, because they needed to learn something new, or because they wanted to show off the clever way they’d solved a problem.

8. Achievement Unlocked.

Giving new users something to strive for—like Stack Exchange’s Reputation system that allows them to get past basic restrictions, or Quora’s Top Writer program—are another way to drive newcomers to increase their participation levels rather than drift away.

Self Control – En hjälp att hantera databeroende.

Skärmavbild 2015-06-16 kl. 23.10.33Jag har bara en bra grej men den är riktigt bra.

Om du sätter dig ner för att göra något viktigt är det stor risk att du ”råkar” kolla något annat först och så går tiden utan att du gör det du egentligen borde göra.

För Macanvändare finns programmet SelfControl (gratis). Där skapar du en Black List med alla sajter som du inte borde besöka. Sen ställer du en timer och trycker start. Nu kan du jobba utan att lalla iväg för det går inte. SelfControl blockar alla sajter tills tiden är slut. Du KAN inte komma runt det utan att installera om datorn.

Just nu fick jag lust att kolla en grej på Quora.com men det går inte för det är 2 minuter kvar av de femton minuter som jag tänkte att det tar att skriva det här inlägget.

Edit: Och nu går det bra att surfa på alla sajter som ligger på Black List igen.

Why the modern world is bad for your brain

Why the modern world is bad for your brain är en artikel i the Guardian som behandlar hur det moderna samhället påverkar våra hjärnor på ett synnerligen negativt sätt. Strömmen av information och stimuli ger ökade nivåer av kortisol, adrenalin och dopamin. Vårt fladdrande på nätet stimulerar ett nyhetscentra i prefrontala cortex att ständigt vilja ha mer nyheter. Man kan likna det vid ett drogberoende. Som förälder till en tioåring och en fjortonåring känner jag igen detta i alla konflikter som uppstår när vi vill begränsa deras telefonerande. jag är allvarligt oroad att de förstör sin framtid.

Nedanstående stycke sammanfattar det hela på ett tankeväckande sätt.

Multitasking has been found to increase the production of the stress hormone cortisol as well as the fight-or-flight hormone adrenaline, which can overstimulate your brain and cause mental fog or scrambled thinking. Multitasking creates a dopamine-addiction feedback loop, effectively rewarding the brain for losing focus and for constantly searching for external stimulation. To make matters worse, the prefrontal cortex has a novelty bias, meaning that its attention can be easily hijacked by something new – the proverbial shiny objects we use to entice infants, puppies, and kittens. The irony here for those of us who are trying to focus amid competing activities is clear: the very brain region we need to rely on for staying on task is easily distracted. We answer the phone, look up something on the internet, check our email, send an SMS, and each of these things tweaks the novelty- seeking, reward-seeking centres of the brain, causing a burst of endogenous opioids (no wonder it feels so good!), all to the detriment of our staying on task. It is the ultimate empty-caloried brain candy. Instead of reaping the big rewards that come from sustained, focused effort, we instead reap empty rewards from completing a thousand little sugar-coated tasks.

 

 

 

 

What is going to be the next ”big thing” in the next 5-10 years?

Answer by Nitin Balodi:

In next 5-10 years, the face of technology will be completely different from what it appears today.  Everything will be turned into its smarter versions and in another time frame of 5-10 years, these smarter systems will get turned into their smartest version.

According to me there will be
1.      Smarter (not smart) phones
2.      Smart cars (eco-friendly, driverless) ,
3.      Eco Friendly Energy Grids and Transport System
4.      Smart currency or payment methods
5.      Smarter Communication means

Now let me tackle them one by one to justify my point to some extent. So I am starting with a device that you may be holding right now. Yeah the Smartphone .

Smarter Phone –The smartphones that we use today, in a time frame of 5 to 10 years will be converted into a smarter phone. It will be loaded with more amazing features like Augmented Reality (AR), Artificial intelligence (AI) , better batteries (made up of Graphene), loaded with emotionally intelligent phonebooks, smart apps, and with a flexible structure that can be rolled like a paper. Therefore, we can say that the smartphone will be converted into an intelligent gadget.

Think of a situation where your class teacher will be taking attendance and sending notes and marks on your smartphone by using AR app. Kind of a smarter class room.   (Samsung: Using Augmented Reality to Provide A Smart Classroom).

Let say you are in a new city and you have to go to an address for the first time. No need to worry you will be having AR app in your device and it will help you and that too by merely clicking a picture of your surroundings. Let me give you a bird eye view.

You will set your destination, will capture an image where you are currently standing, and will process that image. The AR app will detect your location and a 3D view of your surrounding will superimposed on your device screen. The heading of my camera will be identified also and according to your destination, an arrow will appear on the device screen.

This much wonderful an AR app can be.  I am making this statement based on the patent applications I studied that are filed by Samsung, Apple are other tech giants on Augmented Reality.

Apart from that there are going to be Apps that will be saving you from running out of batteries. One such app is proposed by Google (Google – Battery Saving Android App that Never Let Your Phone Die).

Graphene, which is a form of carbon, could change the way our devices look, feel, perform and even interact with our bodies. It can completely replace the lithium ion batteries that we currently use. Manufacturing of thin, flexible batterieswill be facilitate by Graphene that could enable wearable computing also.
Northwestern University researchers built a battery made of graphene and silicon, which supposedly lasted over a week on a single charge and only took 15 minutes to juice up. If graphene goes mainstream, you could possibly leave your smartphone charger home when traveling
Graphene battery tech: charge your smartphone in 20 seconds
Graphene Could Kill Lithium-Ion Batteries

There will be Apps that will be recommending food for you and helping you to stay fit and follow your daily diet goals. You will be using a flexible smartphone that can be bent, rolled and folded like a paper.
The phonebook of your smartphone will be storing the emotional information of the callers that will be updating the contacts. One such phonebook has already been proposed by Samsung electronics. (Innovative Phonebook by Samsung that Detects Emotions) Thus you will be carrying an emotionally intelligent device in your pocket.

Not only this, due to the IoT (Internet of Things) your smartphone will be communicating with your AC, refrigerator, washing machine, car and the like. You will be in shopping mall and your refrigerator will come to know about it though the GPS location of your smartphone and will be sending you a reminder that you have to purchase butter for tomorrow’s breakfast.

You will be connecting your smartphone with your AC and will link it with the alarm clock of smart phone. And whenever you will stop the alarm ring, the AC will be turned off. Is this sounding like Sci-Fi? Check this link and the also the reference of patent application that is mentioned there. LG: The Multifunctional Android Alarm Clock App

Apart from this your smartphone will be doing health monitoring and will be taking data from the wearable devices like bands, earphones and sending that to the medical server for further examination by your doctor.
As I was saying earlier multiple technologies (AR, AI, and IoT etc.) will be converging to convert a smart-phone into a smarter-phone.

2. Driverless and Eco Friendly Cars
There will be driverless cars that will be carrying computers under their hoods that will be utilizing artificial intelligence to make decisions on road.  The driverless car project of Google is well known to all of us. The car can identify, track and predict the movements of pedestrians, bicycles, other vehicles, or objects like road signs in the roadway. It can read road signs, can diagnose itself, can pick and drop you from anywhere you desire and can do many other cool things. How Driverless Car Predicts Expected Movement of Objects on Road?

If you are interesting in knowing more about the driverless car project you can consider this link – The Future of Technology

While Google is making driverless cars, Tesla on the other hand is marching toward a future of eco friendly electric cars. Even Tesla is also working on driverless car technology. At present, the S model of Tesla costs you around US $70,000. However, soon this price will be reduced to around $35,000.  Tesla Motors recently closed its deal to acquire the 980-acre site in an industrial park outside Reno where it has already begun pouring concrete for a giant lithium-ion battery factory. The gigafactory is intended to produce 500,000 battery packs a year.

Please follow these links to know more about Tesla and its Gigafactory. Tesla Timeline | Forums | Tesla Motors
Tesla closes on free Nevada land for gigafactory
I may not be wrong to call these cars as smart cars and these two projects as next big thing.

3. Smarter Energy Generators and Transport System
On top of everything, I am an avid fan of Elon Musk and hence after Tesla again I am going to mention about Hyperloop that is put forward by Elon Musk. And I am going to talk about Hyperloop. It’s a high-speed transportation system.

Basically, the system would work like those old pneumatic tubes that were used to move messages using air pressure in banks, newspaper offices and other buildings in the mid-20th century. ”The Hyperloop design uses a combination of low air pressure and magnetic acceleration to get people from LA to SF in just about 30 minutes,” The 400-plus-mile trip would take less than an hour, compared to more than six hours of driving.

This is a kind of transportation technology that allows Angelinos to commute to job in Vegas or San Francisco or wherever it ends up, is going to make neighbors of literally distant strangers. Suddenly, people who live in different cities will eat lunch in the same restaurants. They’ll share cabs (arguably robo-driven cabs, but cabs none-the-less). They may go to the same gym. In this way, the Hyperloop will radically extend our interpersonal networks in ways we can’t image and, by extension, reshape the way we do business.

I know you are a curious soul and want to read more about it. Here I am saving your fingers from typing again .
Hyperloop
These Dreamers Are Actually Making Progress Building Elon’s Hyperloop | WIRED
Why the Hyperloop isn’t wishful thinking
So after the transportation let me move ahead to the smarter energy generators. Have a look at this –

This is airborne windmill. The concept of airborne wind turbines is close to becoming reality. Altaeros has already built the world’s highest turbine that can generate twice the energy output of its ground-based counterpart. Besides generating power, these floating power plants can provide data coverage, cell service and local weather data and can be deployed in harsh weather conditions.

It’s a dramatic idea that could change the course of countless lives around the planet. Suddenly, with airborne wind turbines, isolated communities in South American jungles or Alaskan islands could have easier, cheaper access to technology that most take for granted.

4. The Smart Payment System – Crypto Currency
In future, I believe Bitcoin is going to be very popular among peoples around the globe. Its decentralized DIGITAL currency that is fast, cheap and secure to use.  Your bank charges you for international transfers and when you use your credit/debit card to purchase things. However, Bitcoin doesn’t. Moreover, there is no need to give your real name as each bitcoin transaction is recorded in a public log, names of buyers and sellers are never revealed – only their wallet IDs.
While that keeps bitcoin users’ transactions private, it also lets them buy or sell anything without easily tracing it back to them. That’s why it has become the currency of choice for people online buying drugs or other illicit activities.
I would like you to explore this link to know more about Bitcoins – What is bitcoin? – CoinDesk

5.  Smarter Communication
Earlier we had telephones where we could only communicate through voice calls, then came the era of text messages and mms and later of the video calls.  In past two or three decades, you can easily decipher the changes that have come and are still coming in the way we communicate.
Now coming the era of Telepresence that will take communication to the next level. Telepresence is capable of providing you a kind of experience where you can’t distinguish between a real life image and the one that created by this technology, its experience would be equivalent to meeting in person.

Have a look at this device also This Ingenious Augmented Reality Mirror will Take Telepresence to A New Level
It could be so close to actually being there in person.  It is already prevalent, however only big corporate companies and organizations are utilizing such technologies as these are expensive. But we can expect it to become cheap when common person will be able to use it.

Congratulations you just have read a short article of 1680 words. Have a great day.
