8 hours ago in "Agentic pods" framework is IMO a must read from Uber 's CTO Praveen Neppalli Naga on agentic AI adoption beyond engineering.
I think it's powerful because it's super simple: they just paired 30 of their most AI-proficient engineers and paired with a domain experts from a business function for 2 weeks.
- Days 1 – 2: Shadow the expert. Observe every step. Document workflows. Ask questions. Build intuition.
- Day 3: Prioritize opportunities based on scale, repetition, business impact, and data availability.
- Days 4 – 5: Build a working agent alongside the person doing the job.
- Days 6 – 9: Validate with several others performing the same work. Does it generalize? Does it actually make their job better?
- Day 10: Ship.
No big projects, committees, just pure hands on and discovering by sitting next to the people doing the work.
I would maybe add only one rule to this framework to make a 10-day sprint possible: limit the scope to a maximum of 3 tools. If engineers are given a blank canvas, they might spend 10 days setting up the infrastructure (worst case!). So the initial challenge is: you have to duct-tape it first. We use this exact philosophy at Appliscale and Our Head of Ops, Magda Sleboda, automates massive chunks of our company using just an LLM, Airtable, Slack and Google API. Highly recommend following her feed or asking her directly how she builds these workflows!

12 hours ago in Recently I measured HTTP/3, the newest version of the web's core protocol, against HTTP/2. There is an older lever on the same traffic worth measuring too: the TLS version underneath it. So I put TLS 1.2 against TLS 1.3 on the same test.
TLS is the encryption layer under HTTPS. Before any encrypted request, the two machines do a short back-and-forth to agree on keys, and that is the handshake. TLS 1.2 takes two round trips: the client and server first negotiate which cipher and key exchange to use, then swap keys in a second round. TLS 1.3 cut that to one. It dropped the old, weak options so there is little left to negotiate, and the client sends its key material in its very first message instead of waiting for the server to pick. One round trip on setup instead of two.
The catch is that most traffic never pays for a fresh setup. A busy client keeps a pool of connections open and reuses them, so the handshake is paid once and then thousands of requests ride the same warm connection for free. On a warm connection there is no handshake to save, and the TLS version stops mattering. The version only matters when a connection is new. Connections do get replaced: they drop, they time out, they get recycled when a system scales up and down. So the real question is how often that happens, and how much each new connection costs depending on the TLS version.
Setup: sender and a receiver far apart, traffic over the public internet, about 100 milliseconds round trip. Then I made a share of the requests land on a brand-new connection, a fresh handshake, and raised that share from zero, running the same traffic over TLS 1.2 and TLS 1.3.
With no fresh connections, the two are identical. As the share of fresh connections rose, the typical request held at the same speed for both, because most requests still ride warm connections. The whole cost landed on the requests that hit a new connection, and there TLS 1.2 ran about a third slower than TLS 1.3. That difference is one full network round trip, the extra handshake leg TLS 1.2 does and TLS 1.3 skips.
One step I did not measure: TLS 1.3 can resume an earlier session and send its data in the very first packet, with no handshake round trips at all (0-RTT). On a repeat connection that would cut the cost to zero. It carries a risk, though. With no round trip to prove the client is really there, anyone who captures that first packet can send it again later, so 0-RTT is only safe for requests that cause no harm if they run twice.
So the TLS version is worth exactly as much as your connection churn. Keep the connections warm and reused, and the newer one buys you almost nothing. Let them churn, and the older one costs a round trip on every fresh connection. And that round trip is only as long as the distance it crosses: sit the sender and the bidder close together and even a fresh handshake is cheap, so the version barely shows there either.

12 hours ago in Recently I came across some interesting data.
Youth unemployment across the EU - Poland sits at 12.4%, below the EU average of 15.2%, and among the lower rates in the bloc.
Consistent, not a spike. Polish youth unemployment has run under the EU line for years, and overall unemployment is 3.1%, among the lowest in Europe.
When we put it next to the other signal - Poland now the world's 21st largest economy, closing in on the top 20 - a picture forms. A market that works, and young people who can find a place in it.
That's the ground we hire and build on.

2 days ago in HTTP/3 is supposed to handle lost packets better than HTTP/2. I set up two machines far apart, sent real bid traffic between them, and added packet loss to measure the difference. How big that gap gets is set entirely by the path.
HTTP is how a browser and a server talk: a request goes out, a response comes back. HTTP/3, from 2022, changed the plumbing underneath. Older versions run on TCP, which hands over the data in the exact order it was sent. HTTP/3 runs on something newer, called QUIC. HTTP/2 sends many requests down one shared line at the same time. Because TCP keeps everything in order, if one packet goes missing, everything behind it has to wait for it to be resent, even the requests that already arrived. HTTP/3 gives each request its own lane, so a lost packet only holds up that one request and the rest keep moving.
That is the theory. I wanted real numbers. So I set up a mocked exchange and a bidder far apart, with their traffic going over the public internet instead of a clean line. The exchange sent real bid requests, and the bidder replied with a real bid on 1 in 100 and skipped the rest, the way a real one does. Then I added packet loss a little at a time, running the same traffic over both HTTP/2 and HTTP/3.
I put the two far apart on purpose, so even with no loss both land around 100 milliseconds, the round trip for that distance. At that baseline the two behave exactly the same. Loss is where they split, and it hits the slow requests first. Look at the slowest 1 in 20 requests. With HTTP/3 they stayed between 100 and 104 milliseconds however much loss I added, so 19 out of 20 responses were basically unaffected. With HTTP/2 those same requests climbed steadily: about 150 milliseconds at half a percent loss, 175 at one percent, and 200 at two percent. One lost packet holds up a whole batch at once.
Compare that to a bidder running inside Index Exchange’s Index Cloud datacenter, right next to the auction. Packets get lost out on the open internet, where traffic crosses many congested hops between different networks and overloaded routers drop what they cannot queue. A few meters across the datacenter's own wiring crosses none of that, so the round trip stays under a millisecond and almost nothing is dropped. HTTP/3's whole advantage is recovering from lost packets, and here there are almost none, which is why my test showed no gap at all with the loss switched off.
HTTP/3 is a real answer to the packet loss of the open internet, and the far-apart numbers earn it. Its benefit rises and falls with how much the path loses. Put the bidder next to the auction, and there is almost nothing left for it to fix.

2 days ago in Golf courses use 31x more water than all US data centers combined, the land used for data centers is microscopic compared to idle farmland + data center growth actually subsidized and lowered residential electricity rates by approx. 6% (they provide massive, predictable 24/7 demand, sp power companies can operate their grids more efficiently).
But I think there's a catch that macro charts miss:
1) we are currently shifting from traditional CPU cloud architecture -> heavy GPU agentic workflows and GPUs require entirely different power densities per 1m2
2) data centers don't draw power evenly across the country - they are pretty concentrated in specific zones (e.g. Northern Virginia, 650-700 data centers and approx. 25% of US capacity) so it doesn't matter if data centers use a fraction of the nation's total water / power if they completely overwhelm the local grid capacity. In short: you can't just plug a 100-megawatt AI cluster into a local grid without breaking the local infrastructure because cooling requirements for a rack of H100 GPU clusters are totally different than a rack of standard web servers
It is exactly like managing traffic: doesn't matter if your servers can handle a billion requests a month on average. If 10 million of those hit one specific endpoint / sec during a live sports event, the system crashes. Averages look great on paper, but infrastructure always breaks at the local bottleneck.

3 days ago in "Only 2.2% of U.S. housholds pay for an AI subscription" might mean "there's lots of room to grow" or a bearish case "most people don't want to pay for AI". But there's another take somewhere in between - as someone noticed on X:
"the reality is that if you're building with AI, you're instantly among <1% of the population and if you've even made a single dollar off of something you've built, that number drops significantly.
keep in mind, most people are using AI as a search engine, doctor, therapist, etc - not to build a SAAS

6 days ago in A long time ago, we created our standard employment contract at Appliscale . Since then, we've made only minor changes, and for years we received almost no questions about it from employees or candidates.
That changed recently.
Whenever we started sending an offer together with the contract draft, candidates began coming back with detailed lists of questions, concerns, and negotiation points.
At first, we were a bit surprised. The contract hadn't really changed, so what had?
After talking to some candidates, we discovered that many of them were running the contract through ChatGPT and other LLMs before signing.
The interesting part was that the models were consistently flagging some clauses as unfair, risky, or even suggesting that we might have bad intentions.
So we went back and reviewed those clauses with our lawyers.
One example was a clause related to damages caused by serious misconduct. The LLM flagged it because the contract did not explicitly limit the maximum amount of damages — suggesting that, theoretically, the company could claim an unlimited amount.
The missing context was Polish law.
Under Polish regulations, contractual penalties are not simply enforced blindly. They are adjusted based on the actual damage and circumstances. A lawyer familiar with Polish law would immediately know this. Adding a detailed explanation in the contract would mostly repeat what the law already says.
But the LLM didn't know that.
So we added a sentence explaining this explicitly. Nothing really changed legally, but it changed how the AI interpreted the contract. After uploading the updated version, the warning disappeared.
The whole thing made me think about something else.
We often talk about AI helping people understand complex documents, but we rarely talk about the fact that documents themselves might start evolving to "communicate" with AI.
And this raises an interesting question: how long before people start writing contracts that are not only legally correct, but also optimized to pass AI reviews?
Of course, on the positive side, this could make contracts clearer and easier to understand.
On the negative side, I can imagine a world where someone learns how to phrase things so that an AI reviewer says "looks fine" while a human misses the hidden risk. We already know that people can manipulate humans with careful wording. Will we now need to learn how to defend against documents designed to manipulate machines?
So just an interesting side effect of everyone suddenly having an AI lawyer in their pocket.

1 week ago in To an embedding model, "adults aged 25 to 34" and "adults aged 35 to 44" are the same audience. Across nine models the two brackets score 0.93 to 0.98 out of 1.0. The number that defines the segment barely registers.
Embedding-based audience matching turns a description into a vector and matches by distance, so closeness of meaning becomes closeness of vectors, scored by cosine. It works for fuzzy intent, and it falls apart on anything defined by a number, and standard targeting is full of those: age brackets, income bands, price caps.
I embedded pairs of standard adjacent audiences that differ by one number, on nine models: Google and OpenAI across three generations, plus open models from 22 million parameters up to an LLM-based one. Every model, every pair, scored between 0.88 and 0.99. Age 25 to 34 against 35 to 44, income 100 to 150k against 150 to 200k, all nearly the same vector.
That number only means something against a baseline, so I added one. On text-embedding-3-large the neighbouring bracket "aged 35 to 44" scored 0.93 against "aged 25 to 34", while an unrelated audience scored 0.30 and the same bracket reworded scored 0.79. The neighbouring band came out closer than the same band said two ways. The models separate audiences fine, they just cannot separate two that differ by a number.
The reason is in the pieces the model reads. A tokenizer chops text into dictionary fragments, and a number is no exception: "30,000" goes in as "30", ",", "000", and "35,000" as "35", ",", "000". Two of the three pieces are identical, and the one that differs, "30" against "35", is just another entry in the dictionary. Nothing in it says 35 is larger than 30. The two sit close only because they turned up in similar sentences in training, next to prices and ages. Then the model squashes all those pieces into one fixed vector, so flipping one fragment among a dozen barely moves it, while a word that changes the whole meaning, budget against luxury, moves it much more.
So the model can drop a number in roughly the right neighbourhood by association, but it cannot compare two of them. A bracket is defined by the one thing the model skips, the boundary. That is why the number stays an ID next to the vector and does not fold into it. A vector ranks how close a meaning is. It cannot count.
One caveat: these are general-purpose models trained on the open web, not on ad data. A model trained on ad data would place common price points better, but comparing two numbers is still not something embeddings do.

1 week ago in Everyone is sharing their AI harnesses, skills.md files, MCP setups, and elaborate agent workflows and those are great but sometimes the highest ROI comes from much simpler infra.
So the problem is following: AI coding agents (Claude, Codex, Gemini, Copilot, etc.) occasionally run catastrophic commands like git reset --hard, rm -rf ./src, or DROP TABLE users—destroying hours of uncommitted work in seconds.
The solution: this library dcg is a nice reminder that guardrails don't have to be complicated. It intercepts destructive commands before they execute, blocking them with clear explanations and safer alternatives.

Then I waited.

2026, and it still just clears.
No jailbreak, no adversarial suffix, no clever encoding. Just words sitting in a place nobody scoped as untrusted, doing exactly what they were told.

Someone turned the Bitcoin order book into a video game, an actual 3D battlefield.
- Buyers charging from one side
- Sellers pushing from the other
- Whales rolling + liqudations getting blown up live on the battlefild
Sounds like a fun project but it also shows that the right visualization can change how we think about data - especially in high-frequency data stream like trading or ad tech: nothing about the underlying market changed, only the interface did but suddenly your brain starts seeing strategy, conflict, momentum, and patterns that were hidden in a spreadsheet.

1 week ago in The bid window is short. Web and mobile auctions run on roughly 120 millisecond deadlines, CTV a bit longer, closer to 300. Still fast either way. Confirming that the ad actually won is a different matter.
On desktop, the median gap between a win and a confirmed impression is 2 seconds. Mobile lands at 2 seconds too. Tablet at 3. They stay fast well past the median: ninety percent of desktop confirmations land under half a minute, and even the slowest one percent, the real stragglers, come back inside four minutes.
CTV runs on a different scale entirely. The median lands somewhere between a hundred and several hundred seconds depending on which record you check, and the distribution only stretches further from there. Ninety percent of CTV confirmations land within about half an hour. Ninety-nine percent take longer than an hour and a half. The slowest one I traced ran just under three hours before the impression ever confirmed. CTV's slowest one percent alone takes more than twenty times longer than desktop's slowest one percent.
The bid window rules itself out as the cause. It stays sub-second on every device, so decisioning speed isn't the variable moving here. Whatever produces the gap sits entirely downstream of the auction, in whatever has to happen between a winning bid and an ad reaching a screen.
The reason sits in what confirmation is waiting for. It doesn't fire when a bid wins, it fires when the ad plays. Desktop and mobile render in about two seconds, so that follows the win almost immediately. CTV ad delivery is stitched into the video stream and gated behind whenever the viewer's own playback reaches that point, live schedule or on-demand session either way, so the same event can take minutes to fire, or longer if the viewer paused or stepped away. The confirmation isn't slow. It's waiting on something that takes seconds on one screen and anywhere from minutes to hours on the other.
That gap is something reporting, pacing, and bidding logic all have to be designed around for CTV specifically, not something a general-purpose number handles on its own. A dashboard built for web traffic assumes the number it shows is close to final. A pacer built the same way assumes delivery so far is roughly what's confirmed so far. Both assumptions need their own handling on CTV, because confirmed and delivered are running on two different clocks.

2 weeks ago in A Gemini audience vector is 3,072 numbers. I deleted 2,304 of them, kept the first 768, and every audience in my test still matched the same ones. The order those numbers come in is not an accident.
Two posts back I showed an audience vector weighing about eight times the whole bid request, with two ways to shrink it: store each number in fewer bits, or carry fewer numbers. The first was quantization, where int8 gave a free 4x. This is the second, and the more surprising of the two.
Start with what those 3,072 numbers are. Each is a coordinate on the model's map of meaning, and on its own a single one tells you nothing: there is no "luxury" number to point to, no slot for "in-market for a car." The meaning is smeared across all 3,072 at once, so you would expect every number to matter and dropping any to hurt.
These models do something deliberate about that. Gemini's is trained with a technique called Matryoshka, after the nesting dolls that sit one inside another: the first 768 numbers are a complete, usable vector by themselves, the first 256 a coarser one inside that, and so on down. The full 3,072 is the outermost doll, with smaller working vectors packed in from the front. The tail adds detail; the front carries the gist.
This is literal. Ask the Gemini API for 768 dimensions and it hands back the first 768 numbers of the same vector, nothing recomputed: I checked its answer against my own front-768 slice and they line up at cosine 1.0000. Fewer dimensions means keep the front and renormalise.
So I ran the ladder on the same 24-audience library. Cut from 3,072 to 768, four times smaller, and the matches are identical: every nearest neighbour is the one the full vector picked, and my three tiers barely move (0.956, 0.871, 0.809 against 0.956, 0.879, 0.823). Push further and it costs: by 256 dimensions the exact nearest neighbour holds for 88% of audiences, by 128 for 79%, and the cosine value drifts upward as fewer axes crowd together. Yet the right concept still ranks first all the way down to 32 numbers. The score loses its meaning long before the ranking does.
Which 768 you keep barely matters on a set this small: the first, last, or a random pick all worked about the same, so the saving here comes from the count of numbers. The front 768 earn their place on large, hard catalogues, which is what the public MTEB benchmark shows, with 768 dimensions about 0.2 points below the full 3,072. And truncation only works on a model trained for it: I ran the same cut on ada-002, never built to pack meaning into the front, and its nearest match scrambled to 79% at an eighth of its dimensions, while Gemini stayed near perfect.
So this is the second way to make an audience vector lighter, after quantization: that one rounded each number, this one drops most of them and keeps the front. Either buys a clean 4x on Gemini before the match suffers, and on a model trained for it the tail is mostly polish.

If you are interested in Agentic AI and Ad Tech, you need to follow Damian. He breaks down the exact mechanics, pulling real numbers from live models to show:
-> Why your targeting precision relies entirely on the tokenizer's dictionary (and why "Saturn" gets split into two meaningless pieces)
-> How the "Attention" layer uses surrounding words to figure out if you mean Coach the designer purse, or Coach the sports trainer
-> The "Squash" (Pooling): How a full paragraph of context gets compressed into a fixed 3,072-number vector
-> The One Golden Rule: Why a buyer and a seller MUST use the exact same embedding model, or the math completely breaks

2 weeks ago in With SIGGRAPH 2026 coming up in a couple of weeks, NVIDIA's paper on MotionBricks is worth a look. It proposes a way to completely bypass traditional game animation graphs.
If you look at modern AAA games, they still handle character movement with techniques from twenty years ago. Brittle state machines, blending trees, and thousands of manual clips stitched together. A game might have 15,000+ animations and a state machine nested 12 levels deep. It is fragile, expensive, and a nightmare to maintain.
This is the generative AI in games we actually want to be seeing.
Instead of generating text or pixels, it is generating the underlying character motion in real-time. They model a dataset of over 350,000 clips with a single modular generative model.
The way it works is keyframe in-betweening. You place a simple target keyframe - like a ledge to climb or a chair to sit on - and the model handles the entire transition dynamically. It is plug-and-play, letting designers author complex locomotion and object interactions in under 10 minutes.
If this makes it into production pipelines, the industry impact could be massive. It points to a way to bypass the animation asset bottleneck completely - letting small teams author AAA-quality movement, and giving major studios a path toward building truly reactive virtual environments.
And the speed is what makes it feel actually viable for production. Usually, generative motion models take seconds to compute. MotionBricks hits 15,000 FPS with 2ms latency on a desktop GPU, and they even deployed the exact same model on a physical Unitree G1 humanoid robot running on a Jetson Orin board.
It feels like we are finally starting to move from rigid, pre-recorded playback to dynamic, real-time motion control.

2 weeks ago in A bid comes back in a hard window, on the order of 100 milliseconds, and on the open web most of it is gone before the request even reaches the bidder. What is left is the real limit on how smart the model can be.
The bigger these models get, the better they do, with no ceiling in sight. In 2024, Meta published a recommendation model called Wukong that kept improving as it grew, out to about 108 billion calculations for a single prediction, far past what a bidder could finish in time. That size is reached offline, in training, where nothing has to answer in milliseconds. The old way to make these models bigger was to give them more memory: a longer table that stores something about each user, page, and ad, and past a point more memory stops helping. Wukong grew a different part instead, the layers that work out how signals combine (this user, on this page, with this ad), and that kind of size keeps paying off.
The catch is in the same paper. A model that big cannot answer inside a real-time serving budget, so the way it reaches production is distillation. You train the big model first, then use it as a teacher: a small, fast model learns from its probabilities, not just the raw clicked-or-not labels, so it comes out close to the big one's quality while staying fast enough to serve. Meituan's SUAN did exactly that, a large model lifted click-through 2.67% in testing, and they shipped a distilled 43-millisecond version to production.
The same squeeze decides how much signal the model can read. Alibaba's SIM showed that feeding the model far more signal per request lifts click-through, 7.1% in their display ads since 2019, but scoring thousands of signals for every request was too slow, so they built a two-stage search: a cheap pass keeps the signals that matter, and the full model reads only those, up to 54,000 in a few milliseconds.
Now look at where open programmatic spends that budget. In a walled garden the model sits in the same data center as the auction, so all of its time goes to computing the answer. On the open web the bid request travels across networks to reach the bidder, and that trip eats 60 to 80 of the roughly 100 milliseconds before the bidder does any thinking. Put the bidder inside the exchange and that trip disappears. Bedrock Platform runs its bidder as a container inside Index Exchange, so the request reaches it without crossing a network. It does not make compute free, the walled gardens are co-located and still distill, but it returns the time lost to distance, which on the open web was most of it.
With that time back, the open web can move toward what these papers point to: a model run closer to full size instead of a distilled copy, far more signal read per request, and more candidates and creatives ranked before the deadline. Co-location also removes the egress cost of the request, so sending the bidder more signal gets cheaper,

2 weeks ago in A full audience vector can weigh up to 12 kilobytes because each of its 3,072 numbers is stored in 4 bytes. Store each in one byte instead and it drops to 3 kilobytes, and in my experiments the matches came out identical.
In one of the recent posts I showed a full audience vector weighing about eight times the entire bid request. There are two ways to shrink it: store each number with less detail, or store fewer numbers. The first is called quantization. A vector is just a list of numbers, each stored to high precision like 0.0734126, taking 4 bytes, because the model works in fine-grained numbers while it learns and hands them to you in that form. Matching does not need that detail, so you can round. Write 0.0734126 as 0.07 and it fits in one byte, four times smaller, which is int8; round to 0.1 for half a byte; at the far end keep a single bit, just whether the number was above or below zero. The catch is that rounding blurs fine differences: 0.073 and 0.071 both become 0.07, so vectors that sat close start to look alike.
I measured what that costs. I embedded this series' 24-audience library with gemini-embedding-001 at 3,072 dimensions, quantized every vector down the ladder, and checked size and matches at each rung.
Down to one byte, nothing breaks. At int8, four times smaller, the three similarity tiers I have shown before are unchanged (0.956, 0.879, 0.822, within a thousandth) and every nearest match is the one full precision picked. Below that it costs, though not where you would expect. At 4 bits the scores drift and the nearest match holds for 92% of audiences. At a single bit, 32 times smaller, the cosine value falls apart and the exact nearest neighbour survives only 79% of the time, yet the right audience comes back: top-results recall stays at 96% and same-concept siblings rank first.
What survives depends on how you use the score. Read the cosine as an absolute number against a fixed cutoff, a match counts above 0.85, and hard quantization breaks it: binary pulled my three tiers from 0.96, 0.88, 0.82 down to 0.74, 0.56, 0.46. Use the score only to rank candidates and take the closest, and the order barely moves: rounding rarely changes which vector is nearest. So a fixed threshold can go to int8 and no further, while a system that just picks the closest can drop to a single bit and still land on the right audience.
How far you can push depends on the model and the data. Published benchmarks keep about 99% of retrieval at int8 and about 96% at binary on a good model, but on some models binary falls to 75%, and my small, clean set flatters binary here. The payoff is large either way: int8 is four times smaller and that cut lands straight on egress, storage and retrieval speed. What quantization cannot change is the count, every rung still carries 3,072 numbers.

2 weeks ago in The biggest irony of the AI revolution is that it is forcing tech companies to become deeply human again.
We have always been remote-first at Appliscale . Working with US clients means late hours, and forcing people to commute to an office just to act as a "social club" kills productivity. We care about results, and we wanted access to a country-wide talent pool.
But recently, the remote hiring market has become quite difficult. Despite the narrative about "mass tech layoffs," finding elite talent is harder than ever.
Here is what I am seeing in our recruitment pipelines:
1) The Layoff Myth. The market is not flooded with top-tier engineers. The massive layoffs mostly hit legacy or low-efficiency units that accumulated mediocre talent. The top 1% are still very hard to find.
2) Geo-scammers. We regularly interview offshore candidates claiming to be in Poland. They use traditional Polish names and claim they have a "Polish father who emigrated to Singapore." Ask them to name a single district in Warsaw, and the call usually ends abruptly.
3) AI-boosted Fake CVs. 5 years ago, faking technical seniority was hard. A few architecture questions would expose a junior. Today, with live interview helpers like Cluey and AI coding aids, it is terrifyingly easy to fake competence on a screen share.
We are adapting, and the solution is highly ironic.
Because AI makes it so easy to fake a CV and an interview, we are using AI to automate 100% of our recruitment paperwork and assessments. Our team spends zero time filling out forms. Instead, we take all those saved hours and dump them into deep, 1-on-1 human conversations with the candidates.
It feels like a paradox, but AI cheating is actually forcing us to shift back to deep, human-to-human relationships to verify who we are hiring. And that's good.

3 weeks ago in Ten roles are live on Appliscale careers page at the moment.
Posting each one took a single click in Airtable. Our site runs on Vercel and fetches directly from that base, so the click is the publish. Taking one down works the same way.
That's not a point about tooling. It's the whole series showing up in one place.
Because recruitment is where our operations actually start. The automations, the internal systems, the lean stack - none of it holds if the way people join is a mess.
So we built that part first.
Steady growth, not explosive. Smart, not loud.
And onboarding? Each step a candidate finishes sets off the next. The system carries the process, so no one has to carry it in their head.
If that's the kind of place you'd want to work - the page is open.

3 weeks ago in A real bid request is about 2,000 bytes. The audience vector that embedding-based targeting would put inside it is 16,000 if not used properly. The vector alone outweighs everything else in the request, several times over.
Embeddings let you target by meaning instead of by segment ID. Let's take a closer look at what that vector could weigh on the wire. An average bid request runs about 2 kilobytes, and since everything on a bid path is gzipped and a request is mostly text and repeated field names, it compresses to about a kilobyte over the wire.
A full Gemini-class vector is 3,072 numbers, each one a 32-bit float at 4 bytes, so about 12 kilobytes of raw data and around 16 kilobytes once it is packed into the request. Next to a 2-kilobyte request that is roughly eight times the size of everything else combined: one field outweighing the device, the user, the page, the impression and the supply chain all together.
Compression does not close the gap. The rest of the request is text and repeated field names, so gzip halves it, while a vector is close to random numbers with no repeating pattern, so gzip barely touches it. The full vector still weighs about 12 kilobytes compressed, against a kilobyte for the request it rides in, so on the wire it ends up around ten times everything else combined.
That is a movement problem before it is anything else. Take an exchange with fifty buyers at a hundred thousand requests a second each, five million a second, around 430 billion bid requests a day. The requests on their own are about 430 terabytes of egress a day. Attach a full vector to every one and you add roughly five petabytes a day, more than ten times that. On public cloud every one of those gigabytes is metered on the way out. If you run the exchange there and pull up the egress line for the vectors alone, you will want to sit down first.
This is also where running the bidder inside the exchange changes the arithmetic. Bedrock Platform's bidder runs inside Index Exchange's Index Cloud, so the request never crosses a network to reach it. To reach a bidder in another cloud the exchange pays egress on every byte of the fat request; to reach a co-located one it pays none, whatever the vector weighs. So the vector's size stops being an egress cost on that hop, which makes it practical to send the bidder more signal than a remote one would justify: several vectors, richer context, things that were never worth shipping across a network.
The full, full-precision vector is more than the match actually needs on the wire. There is a lot of room between it and a vector that still matches well. I will take a closer look at it in the next posts.
Comparing two vectors is cheap, one multiply-and-add per match. Moving them outside the datacenter is the expensive part: a few thousand numbers per user, millions of times a second. That is what you can shrink.

3 weeks ago in Every time you think you need a new dashboard, stop. Ryan is 100% right here.
This is exactly why we built arctus.studio at Appliscale .
After talking to +20 companies we've noticed that most account managers in Ad Tech are drowning in dashboards and at the end of the day, they still have to manually export that data into Excel just to answer a simple client question like: "Why did ROAS drop yesterday?"
The problem is simple: dashboards are static - business questions are dynamic.
So instead of building yet another view in Tableau, we gave an AI agent the ability to understand the underlying database structure. When a client asks, "Why did our Meta spend spike?", the agent queries the database -> reasons through the metrics -> gives you the exact answer in seconds.
If your team is still spending Friday afternoons building reports that nobody looks at by Monday, you need an agent, not another chart.

3 weeks ago in After-Cannes thoughts vol.2: container > agent
Agents, agents, agents, AI - everyone on the main stages talked about it but the most valuable, concrete discussions we had this week weren't about futuristic AI. IMO in the private meetings with top players there was one hot topic (hotter than 31°C in the shade): Containerized Bidders. Yes, less sexy and shiny let's face it - buzzwords don't pay your cloud bills.
Running your bidding engine right next to the SSPs, does. E.g. if you're processing 1M+ QPS, shipping bid requests across different cloud networks easily kills your margin and eats up 20–30ms of your strict 100ms SLA window -> by running the bidder inside the exchange's own environment, whether that is a VPC or the SSP's own data centers, you drop network transit from 30ms to sub-5ms while virtually eliminating cross-cloud egress costs (=good old: faster, cheaper).
The part people miss: once each bid costs almost nothing to process, you stop throttling. The bidder listens to far more of the stream and stops timing out. On the sell side, more bidders reaching more of the stream lifts competition and fill. On the buy side, your cost per win falls. Both without a single model change.
AI agents are incredibly powerful and we're big fan of them in Appliscale , but you cannot deny raw efficiency of the design that just make sense.

3 weeks ago in A player turns 18. Your system removes parental consent. You're compliant.
Not in South Korea.
The Juvenile Protection Act doesn't calculate age by birthday - it calculates by calendar year. Everyone born in 2007 becomes a legal adult on January 1, 2026, the year they turn 19, regardless of when their birthday falls.
A player born December 15, 2007 hits 18 and your system flags them as an adult. Under the Juvenile Protection Act, they're still a minor for another 17 days.
Easy fix: bump the threshold to 19. Except that breaks something else. A January-born player ages out almost 12 months earlier than a December-born player from the same birth year. The logic itself has to change - from "age at birthday" to "calendar year they turn 19."
This is one country, one act. Multiply it across every jurisdiction with its own definition of "adult" - 18 in most places, 19 by calendar year in South Korea, 21 for certain content in some US states - and age assurance starts to look like what it actually is: an active engineering problem, not a policy checkbox.
Getting it wrong isn't a UX bug. It's operating without legally required parental consent for a minor.
