Woke up to like 100 tags on this iPhone implant. Which is found in this video here: https://t.co/9khbpmUQEH

I don’t speak Russian, but I do have a first grade language fluency in hardware. So lets take a look!
Thread 1/n

 So a lot of people have correctly identified it as this GPS & Wifi based location tracker with microphone.
A very common type of device, similar to what is found in those extremely suspicious looking USB cables: https://t.co/uBhi7tRhiW

2/n
The headers are designed to attach a specific USB connector that fits a micro SD card in the tip.
3/n
A repurposed board is very “hobby implant” but... we see the SIM card was removed, which would make this a wifi-only implant. Yet an external GSM antenna is attached and only the ground for power? Cant see the other side though...
4/n
Upon closer inspection, they removed the SIM slot housing and soldered a SIM card directly to the pads. That gains a little more space.

Thanks @dcuthbert

5/n https://t.co/Sq9X6yByPV
You can see an antenna in the upper right. Right on a metal shield which will hurt the range.
There is normally not a convenient place for an implant, but they swapped the battery for a smaller one.
6/n
This feels like a proof of concept done for the video, or a fairly low grade implant done with a tiny budget. It could be done way smaller by not repurposing an existing thumb drive module.

7/n
For many adversaries that want location & mic, I suspect they generally don’t need a hardware implant. But there are always exceptions. That’s not really my area though.
8/n
Looks like @Requiem_fr has a nice visual comparison showing the battery reduction for clearing space.

This is a technique I have also used in power supplies when needing a little extra space for... activities 😈

9/n https://t.co/KjgfREmhZt
If true, this seems almost like it was intended to be found. The work is really primitive for gov work, not to mention the other ways they can pull location & mic.

10/n https://t.co/AwNiFpIE2V
The “shrink the power source” approach was what I used for this project:

11/n https://t.co/gz3cuKC6jb
Here is a previously unpublished picture of the internals. It’s all cannibalized COTS hardware.
This was before I got into hardware design. Not very good, but enough for a proof of concept.

12/n
One plausible idea: this only needed to last long enough to see where the phone went before it was torn open. That would give some valuable info.

13/n https://t.co/M77sGjOmcW
Anyway. I’m just going off a few pictures as I haven’t had the time to properly research it. For all I know, this was created as a stand-in for video demo purposes.

We’ve recently seen research about so-called “bots” and misinformation on Twitter and wanted to share our perspective on why findings that might seem remarkable at first are likely inaccurate. We’re working on a more detailed explanation, but some comments for now.

We continue to be excited by the research opportunities that Twitter data provides. Our service is the largest source of real-time social media data, and we make this data available to the public for free through our public API. No other major service does this.

Many researchers, academics, and journalists use our public API — a set of tools for programmatically accessing information on Twitter. We make all public Twitter content available via our APIs. You can learn more about them here:

The basic issue with much of the research based on our public APIs is simple: The APIs don't provide insight into our defensive actions to protect Twitter from manipulation, including bots.

Because of this, API-based research can't distinguish between accounts we've already identified as bad (and hidden or removed) and real, authentic ones.

X : Our executive team is concerned that we need to up our game in order to out innovate Amazon.
Me : Do you map?
X : Yes
Me : Like this?
X : No. What's that?
Me : A map of a tea shop.


X : Why is that a map?
Me : Long story, all to do with how space has meaning. To keep it short, maps help people to focus on user needs, the components involved, to communicate missing components and scenario play ideas like staff becoming robots.


Me : They’re also good for measuring and managing capital flow, making investment decisions, removing bias and getting rid of duplication.
X : I don’t see how that helps with innovation?


Me : Well, innovation is a tricky word because we use it to describe many things. If you’re talking about differentiation with the adjacent unexplored then you’re experimenting in the “uncharted” space e.g. immortality with magic provided by the special custom built kettle.


X : That sounds like nonsense.
Me : A lot of what people think will be the next great innovation is nonsense. Actually, most of it is. That’s the nature of the uncharted space, it’s experimental, high risk and generally results in failure.
X : We need more reliable innovation.

🕵️‍♂️ How Google's PageRank algorithm works

The PageRank algorithm gives each page a rating of its
importance, which is a recursively defined measure of importance, based on if important pages link to it.
It's recursive because the importance of a page refers back to the importance of other pages that link to it

Here's how it works in practice:
1⃣ We start with some pages and crawl them for links


2⃣ Each page has 1/N points (where N as the total number of pages)


3⃣ Add points to each page for the amount of links to it, divided by the number
of links emanating from the sources of these links

🔥 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.

How to Get Rich (without getting lucky):

Seek wealth, not money or status. Wealth is having assets that earn while you sleep. Money is how we transfer time and wealth. Status is your place in the social hierarchy.

Understand that ethical wealth creation is possible. If you secretly despise wealth, it will elude you.

Ignore people playing status games. They gain status by attacking people playing wealth creation games.

You’re not going to get rich renting out your time. You must own equity - a piece of a business - to gain your financial freedom.

Guruvayur Sri Krishna & Coconut with Horns.
#Krishnaleela
#Bhakthi
🕉
We’ve all grown up listening to stories of Shri Krishna. This one is a famous story of Shri Krishna in Guruvayur Temple, also called Dakshina Dwaraka.


There lived a villager who planted coconut saplings and had promised that he would offer the 'first coconut' from each of his coconut trees to "Guruvayurappan". When the trees started to yield coconuts, he collected the first coconut from all the trees in a sack 👇


and set forth to Guruvayur.

On the way he was stopped by a robber who asked all the items in the sack. The villager told the robber that the coconuts in the sack belonged to Guruvayurappan and so he was unable to hand it over.
@SriramKannan77 @Jayalko1


The robber with anger asked the villager "Is Guruvaurappan's coconut any different? Does it have horns ?".
Saying so the robber pulled the sack forcefully out of the villager's hand, and coconuts came out..👇


To their astonishment each and every coconut in the sack had horns! Even today, the coconut with horns are displayed in the temple for devotees to see.

KANAKA DURGAMMA, VIJAYWADA (AP)
#bharatmandir

Ma Kanakadurgeswari is the supreme Goddess of Andhra Pradesh, seated atop the Indrakilaparvatha at Vijayawada.
This area is called Bezawada as Shiva made a bejjam (hole) in the rocks so that Krishna river could flow freely.


Once, a Rishi Indra Keela prayed to Devi and asked her to reside on his head forever. Devi told him to wait in the form of a mountain in the holy plains of River Krishna.
Later, when Devi killed all demons, she settled on Keeladri as Mahishasura Mardini and fulfilled his wish.


In this place, Arjuna performed penance and fought with Shiva, who had appeared in the guise of Kiratha to win Pasupathastra, the most powerful weapon. So this place is also called phalguna theertha and Vijaywada on account of Arjun’s victory.


Adi Sankaracharya visited this shrine and worshipped the Devi. He installed SRICHAKRAM at the feet of Sri Kanaka Durga.

Adjacent to the Kanakadurga shrine is the shrine of the divine consort-Sri Malleswara Swamy on the Indrakeeladri.

1/ new essay: What's next for marketplace startups? Reinventing the $10 trillion service economy, that's what. Co-authored with @ljin18 https://t.co/fgKbrHTnH5. A short thread 👇

2/ Marketplace startups have done incredibly well over the first few decades of the internet, reinventing the way we shop for goods, but have been less successful services. It's bc services are complex, subjective, fragmented, and often in real life. Makes it hard

3/ There's been 4 major eras at making the service economy work online. The Listings Era, the unbundled Craiglist era, the Uber for X era, and the Managed Marketplace era


4/ Each era has added more value than the last, and utilized technology innovations, from internet to social / "read/write web" to mobile. The "Unbundling Craigslist" era was particularly epic at generating startup ideas


5/ The problem is, all the low-hanging fruit has been picked off. The techniques that got us to here won't get us to the next phase. So we have to do some pretty different things. That's why "Managed Marketplaces" have been a big deal - hire folks as W-2s, certify quality, etc.

Cherthala Karthyayani Temple Prathishta was done by Vilwamangalam Swamy. Chertala Pooram is very famous. Devi is Mangalya Dayini here removes obstacles relating to marriages. Sthala Puranam says that, once 👇


Vilwamangalam Swamiyar was passing this area after Prathista of Padmananbhaswamy Temple, he felt Devi chaitanyam and recognized as Karthyayani Devi. But Devi seeing Vilwamangalam went inside the pond. Swamy searched for Devi continously for 6 days and on 7th day Vilwamangalam


got hold of Devi's hair. Thus only Devi's head is Prathishta here. Devotees do Kozhi parathal ( offering cock) here as an offering to Karthyayani Devi.
