Remember when Meta was planning to charge a $20 monthly subscription fee for the smart glasses feature that lets people hear each other more clearly - even though that feature runs locally on your glasses and doesn't require the cloud? Meta has paused those plans, spokesperson Tyler Yee confirms to The Verge. The company is […]

If your app sends email — transactional or marketing — three DNS records decide whether it lands in the inbox or the spam folder: SPF , DKIM , and DMARC . Here's how to look them up and sanity-check them in Python, no third-party API required. Install the one dependency: pip install dnspython SPF: who is allowed to send SPF lives in a TXT record on the domain itself and starts with v=spf1 . import dns.resolver def get_spf ( domain ): for rec in dns . resolver . resolve ( domain , " TXT " ): txt = b "" . join ( rec . strings ). decode () if txt . startswith ( " v=spf1 " ): return txt return None print ( get_spf ( " github.com " )) # v=spf1 ip4:... include:_spf.google.com ~all A quick gotcha worth checking: SPF allows at most 10 DNS-querying mechanisms ( include , a , mx , ptr , exists , redirect ). Go over and receivers return permerror , which quietly breaks authentication: def spf_lookup_count ( spf ): return sum ( spf . count ( m ) for m in ( " include: " , " a: " , " mx: " , " ptr " , " exists: " , " redirect= " )) spf = get_spf ( " example.com " ) if spf and spf_lookup_count ( spf ) > 10 : print ( " ⚠️ SPF exceeds the 10-lookup limit " ) DMARC: the policy that ties it together DMARC is a TXT record on the _dmarc. subdomain and starts with v=DMARC1 . def get_dmarc ( domain ): try : for rec in dns . resolver . resolve ( f " _dmarc. { domain } " , " TXT " ): txt = b "" . join ( rec . strings ). decode () if txt . startswith ( " v=DMARC1 " ): return dict ( kv . strip (). split ( " = " , 1 ) for kv in txt . split ( " ; " ) if " = " in kv ) except dns . resolver . NXDOMAIN : return None print ( get_dmarc ( " github.com " )) # {'v': 'DMARC1', 'p': 'reject', 'rua': 'mailto:...'} The key field is p : none (monitor only), quarantine (spam folder), or reject (bounce). If a domain sends real mail but has p=none , it's not protected against spoofing yet. DKIM: the signature key DKIM is trickier because you need the selector — a label chosen by the sender that lives at SELECT

"Here’s a more natural, flowing version of that section..."

The same bug hit me in three separate sessions before I fixed it properly. Each time, my orchestrator reached a decision point, tried to present its menu, and burned a turn on a validation error instead of a question: InputValidationError: { "code" : "too_big" , "maximum" : 4 , "path" : [ "questions" , 0 , "options" ] } // abridged; the full payload includes the Zod message Claude Code's AskUserQuestion tool caps every question at 4 options. My menu had 5. First strike: the end-of-run menu. Second strike: a blocker-recovery menu. Third strike: the same recovery menu two weeks later, after I thought I'd fixed it. That repetition is the story. Why this one keeps coming back A one-off validation error is not worth a blog post. What makes this one worth writing up is why it recurred: the cause wasn't a typo. It was a template. Suhail , my Claude Code orchestrator, is a set of markdown prompt files, and its menus live in those files as literal option lists: the template says exactly what to present, and the model presents it verbatim. Five options go into one AskUserQuestion call, the schema rejects it, and the round-trip to the model is wasted. In my runs the model then retried with four options and continued, which is why, the first two times, I let the retry count as the fix. The recovery is so cheap that the bug reads as a hiccup, not a defect. But decision menus are the natural accumulation point of any orchestrator. Every new capability wants a slot: continue, commit, skip, retry, abort, show status. The menu only grows. A 5-option template doesn't fail once; it fails on every run that reaches it, one wasted turn each time, until you fix the template. The failure mode worse than the error The wasted turn is the benign version. Suhail's public changelog records the malignant one: the interactive complete-handler menu grew past the cap, and instead of erroring, the presented menu simply lost its last option. The option that got pushed out of reach was Abort . Abort o

1. Introdução: Elevando a Abstração no Terraform No Artigo 1 desta série, exploramos os fundamentos da separação de código e dados no Terraform utilizando arquivos YAML e a função yamldecode . Aprendemos a carregar configurações básicas por ambiente, o que já representa um avanço significativo na organização de projetos de Infraestrutura como Código (IaC). No entanto, à medida que a infraestrutura se torna mais complexa, a simples leitura de um arquivo YAML pode não ser suficiente para manter a modularidade e evitar a duplicação de código. Este segundo artigo aprofundará nas técnicas intermediárias, focando em como combinar a flexibilidade do YAML com os poderosos recursos de modularização do Terraform. Abordaremos a passagem de configurações YAML para módulos, o uso do meta-argumento for_each para provisionamento dinâmico de recursos e módulos, e a aplicação de funções como lookup e condicionais para lidar com a variabilidade e opcionalidade dos dados de configuração. 2. Modularização com Dados YAML A modularização é um pilar fundamental para a construção de infraestruturas escaláveis e manuteníveis no Terraform. Módulos permitem encapsular um conjunto de recursos relacionados, tornando-os reutilizáveis em diferentes partes do seu projeto ou em outros projetos. Ao combinar módulos com dados YAML, podemos criar componentes de infraestrutura altamente configuráveis. 2.1. Estrutura de Projeto com Módulos Vamos expandir a estrutura de diretórios do Artigo 1 para incluir um módulo de exemplo: . (root do projeto) ├── main.tf ├── variables.tf ├── outputs.tf ├── environments/ │ ├── dev.yaml │ ├── staging.yaml │ └── prod.yaml └── modules/ └── webserver/ ├── main.tf ├── variables.tf └── outputs.tf 2.2. Definindo o Módulo webserver O módulo webserver será responsável por provisionar uma instância de servidor web (por exemplo, uma instância AWS EC2). Ele receberá suas configurações como variáveis de entrada. modules/webserver/variables.tf : variable "instance_type" { descripti

Models are improving quickly, but the cheaper options are often good enough.

Agents that call tools over a network eventually retry a call they shouldn't have. If the tool isn't idempotent, that retry becomes a duplicate charge, a duplicate email, a duplicate order — quietly, with nothing in the logs to flag it. It's a decades-old distributed-systems problem wearing a new agent costume, and as far as I could tell, nobody had shipped a small, pip-installable fix for the agent-shaped version of it. So I built one. It's called latch . Worth saying up front: this is not a novel idea, and I'd rather say so myself than have someone point it out in the comments. The bug, live Here's the whole thing in one file, no library involved: def charge_card ( order_id , amount ): time . sleep ( 0.4 ) # the payment API is a little slow today ledger [ order_id ] += 1 return { " order_id " : order_id , " status " : " charged " } def agent_charge_with_naive_retry ( order_id , amount , max_retries = 2 ): for attempt in range ( max_retries ): thread = threading . Thread ( target = lambda : charge_card ( order_id , amount )) thread . start () thread . join ( timeout = 0.2 ) # the agent's own client-side timeout if thread . is_alive (): continue # "no response, let's retry" return # got a response The payment call takes 0.4s. The agent gives up waiting after 0.2s and retries. The first attempt is still running in the background — it wasn't cancelled, it can't be safely cancelled, Python threads don't work that way. So it finishes on its own time and charges the card. Then the retry charges it again. The agent's own view of the world is "everything's fine, got a response eventually." The ledger says otherwise. This is examples/naive_agent_example.py in the repo, if you want to run it and watch it happen rather than take my word for it. None of this is exotic. It's the same class of problem as "what happens when a payment gateway's webhook fires twice," which every backend engineer who's touched Stripe has dealt with. The fix has a name — idempotency keys — and it's b

1. Introduction Hello from Japan! 🇯🇵 I am an active truck driver in Japan self-studying Python, leveraging my logistics domain knowledge to become a Web Engineer. (English is my second language, but I'm excited to share my journey with developers around the world!) I started my self-study journey on May 12, 2026. In this article, I summarize the process of deploying Ruby on Rails 8 to a PaaS (Render Free Tier) and how I tackled the strict resource constraints I ran into. Check out my GitHub here👈️ (Note: Most repository documentation and commits are currently in Japanese.) 2. Environment Development : Lenovo G580 (Lubuntu 24.04 LTS / 16GB RAM / Upgraded SSD) Production : Render (Free Tier: 512MB RAM) Testing Device : Xiaomi 15T 3. Challenges & Solutions ① Git Repository Structure Inconsistency Issue : An unnecessary .git directory existed inside a subdirectory, causing errors during deployment. Solution : Deleted the nested .git directory to restore repository hierarchy integrity. ② Build Failure via Render Free Tier RAM Limit (512MB) Issue : Executing asset compilation on Render triggered Out-Of-Memory (OOM) crashes, forcibly killing the build process. Solution : Precompiled assets locally and committed the static files to the repository, significantly reducing memory usage on the production build server. ③ SQLite3 Write Permission Error Issue : Encountered database write permission errors during CRUD operations in production. Render's file system is read-only by default, except for designated directories (such as storage/ ). Solution : Updated config/database.yml to direct the SQLite3 database file to a path with write permissions (e.g., under storage/ ). 4. Conclusion By applying these workarounds, I successfully verified the deployment and operation of a Rails 8 application on Render's Free Tier. (Please note: Although production runtime works properly, because the setup prioritizes local configurations, some automated CI tests on GitHub currently report errors.

Every "run this model locally" guide tells you to grab a Q4 GGUF and move on. That advice is fine right up until you try a long-context run and your machine starts swapping. The weights are the part everyone budgets for Quantization maths is straightforward. A model's weight footprint is roughly params x bits / 8 : Quant Bits/param 12B model Quality note Q8_0 ~8.5 ~12.8 GB Near-lossless, rarely worth it Q6_K ~6.6 ~9.9 GB Very close to Q8 Q4_K_M ~4.8 ~7.2 GB The usual sweet spot Q3_K_M ~3.9 ~5.9 GB Noticeable degradation Below Q4 the loss stops being subtle. Instruction-following degrades before raw perplexity does, which is why benchmark numbers can look fine while the model quietly stops respecting your system prompt. The KV cache is the part that bites Here is what the guides skip. The KV cache scales with context length , and it is not quantized by default: kv_bytes ~= 2 (K and V) x layers x kv_heads x head_dim x seq_len x dtype_bytes The practical consequence: a model that loads in 7 GB can need well over twice that at long context. Grouped-query attention helps a lot — kv_heads is much smaller than attention heads — but the term still grows linearly with sequence length while your weights stay fixed. Two knobs matter more than picking a fancier quant: --ctx-size : do not allocate 128K if your prompts are 8K. You are reserving memory you will never touch. KV cache quantization ( q8_0 for K/V): roughly halves cache memory for a quality hit most workloads never notice. Underused. A decision order that works Start at Q4_K_M Set context to what you actually use, not the model maximum If you are still tight, quantize the KV cache before dropping to Q3 Only move up to Q6/Q8 if you have headroom left over That ordering matters: dropping to Q3 to buy context is the most common mistake, and it trades a permanent quality loss for memory you could have gotten from the cache instead. Per-quantization benchmarks and deployment notes for the Gemma 4 family are collected at ge
