Imagine being a German EV driver, not having to register with several of the 400+ EV charging operators just to get energy on the road, but paying with a “Watts” token accepted by any of them.

What would that mean to users and operators?
Thread 1/12👇

 2/12 Based on IOTA “coloured coins”, “Watts” could be coupled to fiat currency or energy units (e.g. kW)

If "minted" by a consortium of EV charging operators, drivers would only have to register with ONE of them to get "Watts" but be able to use them to pay on ALL charging poles
3/12 "Watts" could additionally be sold in "gas" stations or supermarkets like todays' vouchers (cellphone credits, Google Play Store, PSN, Steam, etc).

Sold as vouchers for cash, buying "Watts" would even be (nearly) anonymous.
4/12 If “1 Watts” would be equivalent to 1 cent, minting tokens worth 5 billion € would cost the operators just ~1,500 €.

That’s "dirt cheap" in terms of infrastructure cost, especially when considering that “Watts” could be transferred infinitely w/o ever incurring any fees
5/12 A major headache when it comes to digital (cc) payments usually is "control".

With IOTA-based "coloured tokens", the operator consortium would stay in full control of their "Watts" token. In case they need more than 5 bn worth of them, they could create "Watts" v2 any time
6/12 All 400+ operators currently need to settle with customers individually, incl fees, with payments bouncing, sometimes even defaulting

With “Watts”, operators would only settle among themselves, reducing their overhead of conducting business by 99% + have no risk of defaults
7/12 Without the need to have customers pre-register in order to pre-approve their payment details, operators could ditch large parts of their IT infrastructure, have no payment processor fees and less headaches about security and GDPR - but greatly extend their customer base.
8/12 If “Watts” would be transferable, charging operators could extend their business model by becoming "markets" in allowing EV owners to sell energy to each other through their infrastructure - while retaining a small fee of course.

A “profit only”-opportunity for them.
9/12 EV owners could charge cheaply at night, while power plants produce excess energy, and sell for a small profit during the day, thus level peak energy consumption (& production), resulting in less waste, less cost and wear on the infrastructure.

Literally everybody would win
10/12 The benefits of interoperability aren't limited to EV charging. The Powerwall e.g. already enables transfers between EV and house.

How long until energy can be sold to neighbour houses or even strangers? Impossible based on paper-contracts, but easily enabled by “Watts”.
11/12 Here’s the kicker:

A “Watts” token, if created as "voucher for a redeemable unit", would not be different to any voucher topping up a cellphone, PSN credits, Steam, iTunes, etc.

So, “Watts” would most likely be perfectly legal - already under current legislation.
12/12 The opportunities posed by cheaply "minted", feelessly transferable, secure, „coloured tokens“ seem infinite.

They are only available as "alpha" version yet. But it seems not a question whether a use-case for them can be found, but rather 'when' the first one will emerge.

Singing the Blues:
Taking Down an Insider Threat

"I had all of the advantages. I was already inside the network. No one suspected me. But they found my hack, kicked me off the network...

...and physically hunted me down."


Many pentests start from the outside, wanting to see how the perimeter might be breached.

This pentest started from the inside. My client wanted to assume they had already been breached, and, if breached, how far could an attacker go.

Could they stop me once I was inside?

So they snuck me in. Disguised me as a new employee. Gave me a work computer, an ID badge, an account in their system... hell, I even had a cubicle w/my assumed name on it.

The only person who knew who I really was was their CISO. Everyone else thought I was Jeremy in Marketing.

During most of the first morning, I completed onboarding, made introductions, and completed menial tasks.

But I had to act quick. I only had a week onsite. I had to hack their network while not raising suspicion.

So I set about it.

You have to understand... most "Internal Pentests" are straight forward. The hard part is breaching the network, but once you're inside, it's a target rich environment. End of Life computers, default passwords, everyone a Local Administrator...

The YouTube algorithm that I helped build in 2011 still recommends the flat earth theory by the *hundreds of millions*. This investigation by @RawStory shows some of the real-life consequences of this badly designed AI.


This spring at SxSW, @SusanWojcicki promised "Wikipedia snippets" on debated videos. But they didn't put them on flat earth videos, and instead @YouTube is promoting merchandising such as "NASA lies - Never Trust a Snake". 2/

🔥 It's probably common knowledge that Netlify makes deployment incredibly simple- you can connect a repo, pick a build command and 🚀

or just drop a folder in and you're done!

...but here are some other things you might not know about our deploys that are very special 🧵


Netlify has a concept of "atomic" deploys- which means a few things:

- You can preview a deploy when you've or someone else has just put in a PR

- You can roll back to ANY previous state, with one click, in milliseconds

- You always know what state your cache is in!

Netlify allows you to cancel a deploy- did you just put in a change, merge it and then realize you've made a terrible mistake? I've never done that. 😬 er...

No worries. You can cancel that deploy with the click of a button.

You can lock a deploy. Let's say you get everything ready for a big release, code review and tests are complete, it's all ready.

You can lock a deploy in a state to get ready for a major release, so that you know exactly what you're releasing and sleep well the night before. 😴


You can even get notifications about locked deploys via email, outgoing webhook, or Slack. Netlify can notify you when a deploy is either locked or unlocked.

A long time ago I coded up a feature for SocialCoder which converts a link - any link - to a short URL. I use it all the time for sharing links to volunteer profiles and to volunteer opportunity listings.

The feature doesn't care what the link contains, it just hashes the URL, including any query params, and returns a shortened code.

More recently, around Christmas time, I added another feature where I can click a button to send a template notification to a charity that their new listing has been reviewed and published. I call it a next-steps email.

For the past few weeks, its all been working well. Its nice to keep automating things that previously were done by hand.

Fast forward to today.

A new opportunity listing is posted by a charity.

I review and publish it, tweet about it, then click a button to send the charity an emailed notification of next steps.

So it turns out that Google Chrome was making everything on my computer slow *even when it wasn’t running*, because it installs something called Keystone which is basically malware.

I made a website because this shouldn’t

Wired first reported on how bad Keystone was 11 years ago when they put it into Google Earth (they seem to put it in all their popular

The fact that Keystone hides itself in Activity Monitor is bizarre. (The only sign of it was excessive CPU usage of WindowServer which is a system process).

I don’t know if Google was doing something nefarious with Keystone, or a third party figured out how to (which Wired warned about). But either way, I’m not inclined to give Google-the-organization the benefit of the doubt (despite the many good people who work on Chrome)...

...since it's been a decade+ and this still hasn't been "fixed".

There is no reason for auto-update software to need to do what Chrome/Keystone was doing. It also has a long history of crashing Macs.

SRI LALITHAMBIGAI, THIRUMEYACHUR (TN)
#bharatmandir #navratri2021

Kshetram where Shiva is worshipped as Meghanatha and his consort is Lalithambigai seen in Abhay mudra.
Once, a demon Pandasura was harassing the Devas who went to Devi Parashakti for protection. 
@GunduHuDuGa


Devi rose from a Yaga Gunda, mounted on the Sri Chakra Rath with the name Lalithambika, waged a war against Pandasura and destroyed him.  When her fury did not subside, Shiva asked her to go to Earth, assume the name Manonmani, perform penance and shed her fury.


Shiva blessed Devi to be Shanta nayagi. There is a sculpture here depicting Shiva pacifying Devi. If you observe closely, you can see that from your left hand side there will be a smile on Her face and if you see from your right hand side you can see anger in Her face.


Hayagriva taught the greatness of Lalitha Sahasranama to Rishi Agasthya. Pleased with his devotion, Ma Lalithambikai appeared before Agastya. He is believed to have then sung Lalita Navaratnamala in praise of Devi. He has also composed a hymn named Rahasyanamasahasram.

1) Core attributes of a promising founder worth following:
- Progress/trajectory over time
- How well they lead a team &
- Make the vision happen
- Most impressed when someone is way ahead of where you thought they would be when you check up/see them a few months later.

2) Indie Makers have such a benefit of being small, fast, nimble workers in comparison to big companies.

We can easily pivot and vastly change a project of ours. We can change as we learn more about our users.

Big companies can take months/years for even the smallest of pivots.

3) Before you find a product market you can pivot your project as many times as necessary until you find something that works.

Then you only have one thing to do: scale, scale, scale.

4) Be obsessed with the little details.
- listen to every single person who uses your product
- reply to every single person who emails you about your product
- ask them what they like and do not like
- iterate your product, make changes, pivot if necessary

5) Paul Graham's (@paulg) name came up with a feeling of great admiration! Naturally! It was Paul who said:

In the early stages of a company just;
- write code
- talk/sell to customers to stress test your idea

Nothing else.

If there is one thing I have learned it is that people love bullshit. They buy bullshit stories from professional bullshit artists, accept bullshit philosophies, purchase bullshit how-to-books, vote for bullshitting politicians.

At first, I resisted believing this because it is illogical and dumb and frankly, doesn't reflect well on the human race of which I am a member (and thus have long been hopeful that it is more of a distinction than it actually turns out to be.)

But if you actually are interested in facts you begin to notice how little most people care for them. Sometimes it is because they are heard to learn and bullshit is so much more widely and easily available. Sometimes it is because facts make them uncomfortable about themselves.

Sometimes it is because just one tiny fact will upset a whole worldview that has grown as comfortable as an overstuffed chair. (Settling into such worldviews is a lot like settling into chairs like that because the longer you're there and the deeper you sink...

...the harder it is to hoist yourself up and out of your fat-assed intellectual laziness.) But I actually think the reason people have such an appetite for bullshit goes deeper, goes to an aspect of ourselves we just can't accept.
