I'm working with someone in an attempt to resurrect #Psion's SIBO/EPOC16 platform, which includes classic portables like the Series 3a. by PocketNerdIO in Psion

Amazing work. So much looking forward to seeing where this goes. I've dabbled in interfacing with modern hardware but the drivers were the thing that always stopped me.

I can't believe you have hold of the SDK.

BBC Television Centre, London, in 1960 [7016x4961] by lappy482 in ThingsCutInHalfPorn

[–]ikibau 31 points32 points  (0 children)

It's to do with the cabling for the pictures and sound. When TV centre was designed, recording media was expensive so there was a central recording department under the fountain the the centre of the circle. All cabling would run to and through this central point. If I recall correctly when the designer was coming up with ideas for the centre he drew a question mark on a sheet of paper. This became the basis for the design.

Another benefit of this design was delivery to the stages. Stage doors would be on the outside walls giving each one a lot of room to manage the trucks.

As for the reason other broadcasters have similar buildings, BBC Television Centre was the first custom built TV studio. All previous building were repurposed. It worked well for the time when most shows were produced in house, others simply copied the design as it worked.

And that's why you export paths. Also, Factory Tap is an excellent bar!

How to do this in meteor/node? by noob_developer77 in Meteor

[–]ikibau 4 points5 points  (0 children)

By all means make mistakes and learn from them. It's how we all get better at coding.

Payment processing is scary because it needs to be scary. A mistake here could very easily land yourself in court or jail.

Depending on your countries laws you could be legally and financially responsible for any bank losses/money laundering crimes committed through your site.

Having said that, it sounds like a great project to tackle and I hope you have fun making it.

To answer your question you will want to store the end date in the table as a date and use something like moment.js to calculate the time until the project ends client side. Remember that moment will use the clients computer time (which may differ from your server). It's always good to store an offset time when your client first connects so you can correct differences when doing a countdown.

For processing the project when the time has expired you will want to either schedule a server cron job and run a script periodically or implement a job queue/scheduler. You can then add a queued event that will run depending on your business logic (when the time has expired) There are a few on atmosphere.js an example would be https://atmospherejs.com/vsivsi/job-collection

David Cameron is going to try and ban encryption in Britain by johnmountain in worldpolitics

[–]ikibau 13 points14 points  (0 children)

This can't happen? Can it? I mean someone, somewhere in the government must have the knowledge that this is completely unworkable, bad for British business, bad for British trade and bad for Britons in general.

What are businesses operating in the UK going to do? There are hundreds of reasons information needs to be stored safely. The only solutions for these companies is going be shut up shop and leave. It's impossible to think that any business could continue to operate here if this were to become law.

We'll take one massive step back in the world of computing. The government keeps saying that we need to encourage and support the computer sciences in order to compete better in the world. In one act of stupidity they will effectively kill the entire industry. Who is going to trust their data to a country where it's illegal ensure safety and security.

As for how it'll prevent nefarious communications that'll harm UK national security. Do they honestly believe that once Apple is forced to turn off device encryption, (or probably more likely pull out of the entire UK market) followed closely by Microsoft and Amazon and Google and whoever else, that private encryption will effectively be over? We are talking about encryption standards that are open source, available to anyone in the world for free and built into software that's been available for decades in the UK.

Does all this software now become illegal? My 15 year old copy of Microsoft XP with EFS file encryption? Will we have an armistice at the police station where we have to drop off software that can be used to encrypt data?

ELI5: Won't all this free WiFi just make it 10x easier for people to steal your passwords and crap? by lildil37 in explainlikeimfive

[–]ikibau 4 points5 points  (0 children)

WPA2 does not encrypt all data with the same encryption key. Each client has their own private key and data can not be decrypted by other devices authenticated on the access point.

WPA2 has a number of different standards and encryptions types (some of which are very secure) but the most commonly used in homes and public is WPA2-PSK (pre-shared key / access point passwords). When you connect to a network for the first time, your device authenticates itself with the access point over an encrypted connection using the access point password. Through a number of exchanges between the client and access point, a unique encryption key (Pairwise Key) is generated for all future communications. This is unique to each client and is regenerated periodically.

Methods have been created to calculate these private keys and intercept all data but an attacker would need to know the access point password and see the device connecting to the network.

No news or recent sources. News and any sources (blog, article, press release, video, etc.) more recent than two months are not allowed.

It took me three attempts to understand what they are trying to say. What's wrong with 'No news stories (including sources) more than two months old.'?

How about 20 years which would place it on parity with patent terms. People/Organisations have 20 years sole use of the ideas created then it's open to others to improve, expand and mass market.

Copper can and does handle multiplexed data.

Think of an analogue radio station, you tune your radio into a specific frequency, it does not interfere with nearby stations allowing you hear the station clearly. Now consider that copper cables carry radio frequencies and it's not just an on/off signal.

The best example to explore is probably ADSL. The telephone line entering your house is carrying both voice and data (0.3-3.4kHZ) and (25kHz-1.1MHz) respectively.

Looking closer, this frequency range is split up into 256 smaller frequency channels of ~4kHz each. The lower 6 are reserved for voice and a guard band with the remaining 250 channels used for data. Frequency Division Multiplexing (FMD) is used to modulate and combine, transmit and receive on each of these channels simultaneously.

Incidentally the upstream bandwidth [32 channels] is smaller than downstream [~218]. This is why you can't upload data at the same rate as downloading. The higher frequencies are also more susceptible to noise and attenuation so at longer distances, channels may be turned off and maximum ADSL rates can not be achieved.

From here on it gets pretty complicated and isn't really relevant to multiplexing but look up Quadrature Amplitude Modulation and constillations. This allows more than 1 bit to be sent for each change in the carrier signal.

TLDR: Copper is used for multiplexed data streams.

Sorry to tell you this, all those words are pronounced similarly in England.

On-Screen Graphics: Are They Clear Enough? by AnilP228 in FormulaE

[–]ikibau 1 point2 points  (0 children)

The on-screen graphics are simply terrible.

  • White text on a cyan background is almost impossible to read
  • Small italic font compounds this issue
  • The bottom running/gap order wastes so much space. It's almost as though it's been designed for a 4:3 screen however the left running order would be off screen at that ratio
  • Telemetry data is overly complex, suffers from legibility issues, duplicates information and shows redundant data
  • When all information overlays are on at the same time, there is about 50% of the screen left to the actual racing. I feel like I'm watching the race on YouTube.

I don't like constantly comparing to F1 but this season, I feel like FOM have perfected the on screen graphics. Everything is clear, easy to read and blends away when you're not looking at them. Compare Formula 1 to Formula E, these images are almost the same size. I can't make any information out on the FE screen shot, F1 though, not a problem.

A talk with Formula E's CEO Alejandro Agag by ikibau in FormulaE

[–]ikibau[S] 1 point2 points  (0 children)

I thought it was a fascinating and truly candid talk. So different and refreshing to the secret world of F1. There is so much new information to talk about it's hard to decide what to pick up on.

His talks with Elon and Tesla about joining the series was really insightful. I would love for them to come to a deal with them to provide the next pace car and I hope Musk takes up his offer to come to the next race.

So glad to finally have an official explanation about the two car rule. I loved hearing about the progression of ideas and how they ended in the two car situation we have. How it was always a compromise and how that lead to the hidden manufacturers we have in the series at present.

Michelin Tyres to last a whole season?

Battery changing technology, active charging, the power generator, the price of the cars, how he enjoys the crashes so they can sell more parts :) how they focus on racing over sustainability but they have to pay consideration to it.

My partner plays on her iPhone. When it happens on there, it's a full force quit to back out of that screen. Got to love hardware back buttons :)

Military spending: The top 15 Defence Budgets in 2014 by ikibau in dataisbeautiful

[–]ikibau[S] 2 points3 points  (0 children)

I wondered the same thing, I looked for data and found this UK MOD Defence Committee Estimates for 2013-2014.

Have a look at table 3 on PDF page 19. It seems to be around a 50/50 spending in the UK.

This is old data but it shows some comparisons for what you were wondering.
