I’ve been flooded with Snapchat Spotlight questions after posting I’ve qualified for a payout 4 times. Here are the answers to the most common questions I’ve gotten in my DMs. These answers are my own experience and may differ from others .

Q: How will I know if I am getting paid?
A: You will get a message from Team Snapchat that looks like the below message 2-3 weeks after the snap has gone live. At this point it important that you verify your email address.

Q: How long after I’ve been notified I qualify, will I know for how much?
A: my experience is that usually 7-10 days after you get the qualifying message, you get a message with the amount, it will look like this. This message will include a unique access code for HyperWallet.

Q: How do I set up my HyperWallet?
A: Around three weeks after you get the payment amount you will get an email to your verified email from Snapchat Pay. It will look like this and will require you to fill out some tax forms, takes like 10 min.

Q: How long does it take to actually get the money in my account?
A: it took me like 7 days from when I had my HyperWallet approved before I got the money into my HyperWallet account. I recommend you set up auto withdraw. You can send money to PayPal, Venmo or bank account.

Lockpicking Floppies!

I don't know why twitter is refusing to insert a card for this one. In any case, It's the @LockPickingLwyr, and it's a floppy-drive-lock.

so I've been meaning to do a video or thread on these sorts of locks myself. I have several, of different designs.

generally they're all designed vaguely like this one: it's a plastic insert that goes into the floppy drive, then it has some bit that rotates with the key to hold itself inside.

and they pretty much universally use super-cheap low-security tubular locks like this. You can probably pick most of them with a ballpoint pen

Time for a pulp countdown now, and today it's my top 10 digital watches of distinction!

After all, why wear a Rolex nowadays?

At #10: the 1973 Seiko 06LC. This was Seiko's first LCD wristwatch: a field-effect liquid crystal display showed six digits of time continuously - you didn't need to press a button to see it either!

At #9: the 1976 Bulova Computron. The side mounted LED display meant you could sneak a peek at how long your meeting was taking without anyone else noticing. Very chic.

At #8: the 1989 Nelsonic Nintendo. This is The Legend Of Zelda version and it's perfect for letting others know you are a master of corporate strategy!

At #7: the 1975 Uranus Calculator watch. This natty number has its keypad on the bezel, which does increase its size. "How big is Uranus?" is a frequent question you'll get if you wear this.

I like how mediawiki exports pages because there's nothing I enjoy more than parsing a 1 gigabyte XML file

and I'm doing simple-english-wiki! it's way smaller than english wikipedia
I can only imagine how impossibly unparsable that nightmare is

fun fact: when programmers need to write code to extract data from an XML file, the process usually goes like this:
1. find XML file
2. open it in a text editor, see what the structure is
3. write some code that parses that

do you really want to open a 1 gigabyte XML file in your text editor?

do you want to fucking die?

I used to run into this problem back when I worked for the government, because sometimes I'd click a database query log (don't ask why our logs were in XML, it's... complicated) and it would turn out to be 100mb

I think chrome is intentionally providing shitty user experience for the blocking of HTTP downloads on HTTPS pages, in order to push developers to fix it faster.

you click a HTTP download link on an HTTPS page and what happens? NOTHING. No error page, no pop-up saying "BLOCKED BECAUSE SECURITY", the browser is just like "did you click? I didn't notice"

it just sticks an error in the JS console.

which I'm sure everyone notices

BTW, this is probably going to get fixed soon, but as of Version 87.0.4280.141 (which seems to be latest) there's a bug which lets you bypass the block, most of the time.

Incognito mode.

Basically chrome won't let you download it because it has the context of you clicking it from a HTTPS page.
But it loses the context if you use the "open link in incognito window" option.

Does artificial anthropocentric intelligence lead to superintelligence?

When I use the term Artificial General Intelligence, my meaning of 'General' comes from the psychology definition of the G-factor that is tested in general intelligence tests.

It is an anthropocentric measure. The question that hasn't been explored in depth is whether a "human-complete" synthetic intelligence leads to a superintelligence. The prevailing assumption is that this expected.

I am going to argue that this assumption may not be true.

The assumption that goes into AGI automatically exploding into a superintelligence is driven by the bias that human intelligence is perceived at the pinnacle of all intelligence.

I posted about the Signal messaging application versus Telegram a while ago, and I received a lot of answers about different applications as alternatives. So I'd like to write a thread giving an overview about my perspective on the security of different applications. 1/53

It's very important to remember that this thread is only about messaging applications for mobile phones, and the evaluations are based on my own perspectives and needs. In some cases they will be subjective, and you should investigate before applying the advice to yourself. 2/53

As I've mentioned in previous, when talking about secure messaging applications, it's extremely important to remember that if an application is secure enough, the limitation will not be the security of the application itself, the limitation is the security of the device. 3/53

When talking about security, the weakest link in a chain will be the one an attacker will go after. There are some applications in this thread that are very secure and have great protocols. But if the device is compromised, that will simply not matter. 4/53

So, if you have something very sensitive to discuss, my strong advice is to not trust that information to a mobile device - there are simply too many ways it could be compromised. So, from that perspective, the security of the protocol is not relevant. 5/53

I don't think people have quite internalized *how* the US became the global leader in science and technology. It's partially a story of massive global talent migration.

And it's important to get this story right if we want to maintain

Around 1900, the US was a bit of a scientific backwater when compared to Europe. Most of the exciting work was being done in Germany and Austria, especially.

Then came three enormous waves of academic and scientific talent to the US.

1) First came a group of Jewish scientists fleeing persecution.

In a massive own-goal, 1930s Nazi Germany dismissed ~15% of the physicists who made up a stunning 64% (!) of their physics citations.

The group who fleed to the US included intellectual superstars like Albert Einstein, Leo Szilard, John von Neumann, and Edward Teller who formed the backbone of the Manhattan Project.

In a pithy quote, Churchill’s military secretary Sir Ian Jacob is said to have remarked that the Allies won “because our German scientists were better than their German scientists.”

11 short programming problems to stretch your imagination and make sure you are staying on your toes.

(Starting with the simple ones, they get more fun as you move towards the end.)

🧵👇

1. Write a function that reverses an array in place.

In other words, the function should not use an auxiliary array to do the work.

2. Write a function that finds the missing number in an unsorted array containing every one of the other 99 numbers ranging from 1 to 100.

3. Write a function that finds the duplicate number in an unsorted array containing every number from 1 to 100.

Only one of the numbers will appear twice.

4. Write a function that removes every duplicate value in an array.

There could be more than one value duplicated. You should remove all of them leaving a single copy of the value.

I'm excited to share a new growth framework that @danhockenmaier and I have been developing (with help from the amazing @reforge crew)

I've been finding myself coming back to this framework often when talking to founders about growth.

Thread

1/ As a startup, it's essential that you, and your team, have a clear understanding of how your business is likely to grow. We call this building a Growth Model. With this, you'll know which growth investments to make right away, which to avoid, and which to double-down on.

2/ Our advice is to think about your business like a high-performance race car. The same four components that help a car drive faster also help your business grow:

1. ⚙️ The (Growth) Engine: Self-sustaining growth loops that drive most of your growth (e.g. virality, perf marketing, content, sales)

2. 💥 Turbo boosts: One-off events that accelerate growth temporarily but don’t last (e.g. PR, events, Super Bowl ads)

3. 💧 Lubricants: Optimizations that make the growth engine run more efficiently (e.g. improved conversion, a stronger brand, higher customer retention).

4. ⛽ Fuel: The input that your engine requires to run (e.g. capital, content, users).

Thread: Here's the most fun & frivolous tech news today: Railway Operation Depot in the Chinese city Dalian just published an article on their harrowing journey racing to restore the old version of Flash after Adobe's ban, which collapsed their system and paralyzed the railway /1

The article was written a bureaucratic, propaganda, war diary style, with a detailed timeline down to minutes. "Jan 12, 8:16, Depot received malfunction report. The computer system stopped displaying pages...within 30 mins, computers in the entire depot had the same prob" /2

"After calls and online searches, we identified the source of the issue is American company Adobe's comprehensive ban of Flash content" /3

"8:41, IT department held an emergency meeting & took on four urgent measures: 1. informed supervisors and higher-ups 2. immediately started searching for alternatives to solve page inaccessible issue 3. founded a software task force 4. founded a hardware task force" /4

..."12:10 we temporarily maintained the stability of the depot"
..."13:00 a second crisis meeting was held to address three deeply rooted issues"
..."14:11 another crisis erupted. We are no longer able to print pages, again" /5

A trend I'm excited for this year: DataOps & the Analytical Engineer

~10 years ago DevOps was born. The role of system admins and developers merged. Infrastructure became self-serve

Today the role of data engineers and business analysts are merging. Data is becoming self-serve

Data infrastructure is becoming so powerful that the tools today allow non-technical folks to carry out the once complicated / custom code/ huge backlog jobs of data engineers.

Before getting into what this means, let's first discuss how we got here

Before 2012 the data world was dominated by transactional (OLTP) databases like PostgreSQL, MySQL, etc and analytical (OLAP) databases like Oracle, Netezza

Tools like Informatica / Talend were used to batch load (ETL) data into these databases, Tableau used to visualize

As you can imagine, there was heavy engineering work to manage the environment...

Then in 2013 AWS released their cloud data warehouse Redshift, and it was a game changer. Snowflake was founded in 2012, but didn't really pick up steam until a few years later (around 2016)

So why was Redshift a big deal?

1. It was the first cloud-native OLAP warehouse. It reduced the TCO of an OLAP database by orders of magnitude.

2. Speed of processing analytical queries increased dramatically

Some of the things I've learned in more than 20 years in the tech industry.

You need to hear these.

🧵👇

Listen to more people who don't look like you, don't speak your language, and don't come from the same place you do.

We aren't doing this near enough.

Small habits compound.

No small improvement is too small.

Just aim for something new every day, and you'll be surprised at the end.

Take responsibility.

It doesn't really matter how you feel, I'm sure you could have done better.

Always keep the big picture in mind and never lose the forest for the trees.

Be the person that pulls everyone out of the rabbit holes.

Neural Volume Rendering for Dynamic Scenes

NeRF has shown incredible view synthesis results, but it requires multi-view captures for STATIC scenes.

How can we achieve view synthesis for DYNAMIC scenes from a single video? Here is what I learned from several recent efforts.

Instead of presenting Video-NeRF, Nerfie, NR-NeRF, D-NeRF, NeRFlow, NSFF (and many others!) as individual algorithms, here I try to view them from a unifying perspective and understand the pros/cons of various design choices.

Okay, here we go.

*Background*

NeRF represents the scene as a 5D continuous volumetric scene function that maps the spatial position and viewing direction to color and density. It then projects the colors/densities to form an image with volume rendering.

Volumetric + Implicit -> Awesome!

*Model*

Building on NeRF, one can extend it for handling dynamic scenes with two types of approaches.

A) 4D (or 6D with views) function.

One direct approach is to include TIME as an additional input to learn a DYNAMIC radiance field.

e.g., Video-NeRF, NSFF, NeRFlow

B) 3D Template with Deformation.

Inspired by non-rigid reconstruction methods, this type of approach learns a radiance field in a canonical frame (template) and predicts deformation for each frame to account for dynamics over time.

e.g., Nerfie, NR-NeRF, D-NeRF

Deconstructing AH’s ‘bot’ list - A Thread 🤖
#JusticeForJohnnyDepp
#AmberHeardIsALiar

First things first here’s Amber’s first claim of ‘bots’ included in her Counterclaim (Aug 2020)

“Smear and harass Ms.Heard while simultaneously promoting and praising Mr Depp’s agent and attorney, Adam Waldman.” - This part is specifically important.

There’s 209 accounts listed so I broke them up into 7 groups:
• No Longer exists
• No Connection at all
• P*rn accounts
• Depp Fan accounts
• Only 1 tweet with any link
• Other
• and finally @adam_waldman 🤣

Side note - When I searched the accounts that didn’t obviously show JD tweets (eg fan accs) I searched with the words/#’s
#JusticeForJohnnyDepp, Justice, Johnny, Depp, Amber and Heard

I used all the most commonly used terms with this case so it would throw up anything connected

I can’t search what people have Retweeted but on accounts where there were no tweets to be found, I scrolled back through their profiles for a while to make sure I wasn’t missing anything.
