It centralizes security findings across accounts and projects, supports risk-ordered remediation and CSV export, and provides equivalent checks through the Vercel CLI. Agents can inspect findings, apply supported fixes, and re-check results, with JSON output available in CI and other non-interactive environments.

### Source excerpt

The Vercel Security Dashboard is now generally available on all plans, giving you one place to see your security posture across every account and project. You can access the Security Dashboard in the UI or run vercel security check in the Vercel CLI. As teams grow and coding agents make it faster to spin up projects, small misconfigurations add up quietly. The Security Dashboard automatically flags issues like: Team members without 2FA Long-lived credentials that can be replaced with OIDC Public preview deployments Non-sensitive and stale environment variables The Security Dashboard UI Misconfigurations are ordered by risk with the most severe first, and each finding links to the settings that fix them. Findings that are just noise for your team can also be muted, and all results can be exported to a CSV file for triage or reporting. The Security Dashboard CLI You can also run the same checks in your terminal through the new Vercel CLI vercel security check command, allowing your agents to work through the findings for you. An agent using vercel security check --findings can read what failed, apply the fix and re-check to confirm. Fixes an agent can apply include: Turning on Git fork protection Marking an environment variable as sensitive Replacing a static credential with OIDC federation You can also scope the check to one project with --project when you want a narrow change set. In CI or any other non-interactive environment, the command writes the report to stdout as JSON automatically, giving agents structured output without extra flags. Get started by running your first scan from the Security Dashboard, and learn more in the Security Dashboard documentation. Read more

### AI overview

DuckDB v2.0 will add asynchronous reads for Parquet and CSV files to improve query performance when remote I/O cannot saturate available bandwidth. The article contrasts local SSD workloads with remote data-lake setups using S3 and EC2, where concurrent reads can keep worker threads from waiting on network requests.

### Source excerpt

Starting with v2.0, scheduled for fall 2026, DuckDB will support asynchronous reads of Parquet and CSV files. This can significantly speed up queries when synchronous I/O does not saturate the available bandwidth, as is typical in EC2/S3 compute-storage setups.

### AI overview

This tutorial explains how to send bulk email with Python while protecting sender reputation and deliverability. It argues that a basic smtplib script, CSV mailing list, and sending loop can cause delivery problems without a solid reputation-management foundation.

### Source excerpt

Bulk email has a reputation problem, but users often misplace the blame. Recipients associate bulk email with spam, inbox clutter, and irrelevant marketing campaigns. Senders associate it with poor deliverability, complicated orchestration, and the constant fear of landing in spam folders. If you handle bulk email, these problems may sound familiar. The DIY Python approach -- install smtplib, divvy up your mailing list in a CSV file, set up a loop function, hope for the best -- all but guarantees delivery problems. The mail itself isn't the problem, though. Done properly, bulk email remains one of the most effective ways to communicate with customers at scale. The challenge is that mailbox providers aggressively punish bad sending behavior, even when it's unintentional. Successful bulk email happens when you prioritize your reputation and choose professional-quality tools to maintain it. We'll start with a high-level look at why we focus on reputation and then offer guidance on bulk email sending. Reputation: The start and end goal of successful bulk email Bulk email helps build relationships, educate customers, promote products, and keep brand image fresh. It can be tempting to dive in and start chipping away at those goals, but it's strategy that wins the race every time. Before sending anything to your bulk mailing list, let alone automating your bulk mail with Python code, turn your attention to your sender reputation: Mailbox providers use sender reputation scores to keep bad actors out of inboxes. Bad reputations mean undelivered mail. Your score combines signals from your domain, your content, and how recipients engage with your emails. Recipients read emails from senders they trust, improving your reputation. If they ignore, delete, unsubscribe, or report messages as spam, your reputation declines. The most successful bulk senders understand that reputation, deliverability, and engagement are tightly connected. And they only start sending when reputation manag

### AI overview

Vercel has opened the data behind the AI Gateway leaderboards under the CC BY 4.0 license. The data can be downloaded as CSV or queried through an export API, while charts can be shared as branded PNG images. The leaderboards track daily production usage across models, labs, apps, and inference providers.

### Source excerpt

We are making the data behind the AI Gateway leaderboards open under the CC BY 4.0 license. You can now download or query the data through the leaderboard-export API endpoint and render any chart as a shareable image. The AI Gateway leaderboards show how AI is used in production, ranking traffic for models, labs, apps, and providers. Data is aggregated daily across trillions of tokens, so you can see what gets adopted and how that changes over time. For deeper analysis, see the July AI Gateway Production Index. What's ranked There are four leaderboards, each with its own metrics: Leaderboard Ranks Metrics Models Individual models Requests, token volume, spend, images or videos generated Labs Model labs Requests, token volume, spend, images or videos generated Apps Opted-in apps built on the AI Gateway Token volume, spend Providers Inference providers Token volume, spend Models and labs can be filtered by modality (text, image, video) and show a daily percentage share over time; apps and providers are aggregated across all modalities and show a ranked top list. Open data The data behind the leaderboards is open, published under Creative Commons Attribution 4.0 (CC BY 4.0). You are free to use, share, and adapt it, including commercially, as long as you give credit, link to the license, and indicate if changes were made. Every chart and ranked list has a download button that exports the current view as a CSV. For programmatic access, use the export endpoint, which returns the same data and is cached for 24 hours: For models and labs, each row is one entity's daily share of a single metric. One response includes rows for requests, tokens, spend, imageCount, and videoCount, so filter on the metric field to pull out the series you want. Share a chart Every chart has a share button that turns the current view into an image. Pick an aspect ratio (landscape, square, or portrait), then download it as a PNG or copy it to your clipboard.

### AI overview

A tutorial showing how to build interactive and scheduled AI analysis pipelines with Airflow 3. The pipelines use survey CSV data, generate and run SQL queries, validate schemas, and either request human approval or email results automatically.

### Source excerpt

The 2025 Airflow Community Survey collected responses from nearly 6,000 practitioners across 168 questions. You can open a spreadsheet and filter, or write SQL by hand. But what if you could just ask a question and have Airflow figure out the query, run it, and bring the result back for your approval? This post builds two pipelines that do exactly that, using the apache-airflow-providers-common-ai provider for Airflow 3. The first pipeline is interactive: a human reviews the question before it reaches the LLM and approves the result before the DAG finishes. The second is scheduled: it downloads fresh survey data, validates the schema, runs the query unattended, and emails the result. If you haven't seen the common.ai provider overview yet, start there for a tour of all the operators. This post goes deep on a concrete end-to-end example. Two Pipelines, One Example File Both DAGs live in example_llm_survey_analysis.py and share the same schema context and datasource configuration. example_llm_survey_interactive: trigger manually, review at both ends: prompt_confirmation -> generate_sql -> run_query -> extract_data -> result_confirmation (HITLEntryOperator) (LLMSQLQuery) (Analytics) (@task) (ApprovalOperator) example_llm_survey_scheduled: runs @monthly, no human in the loop: download_survey -> prepare_csv -> check_schema -> generate_sql -> run_query -> extract_data -> send_result (HttpOperator) (@task) (LLMSchema (LLMSQLQuery) (Analytics) (@task) (@task / Email) Compare) The Data The Airflow Community Survey 2025 CSV has 5,856 rows and 168 columns covering everything from Airflow version and executor type to cloud provider, company size, and AI tool usage. A few highlights from the data: 3,320 respondents identify as Data Engineers 2,032 use AWS as their primary cloud provider for Airflow 1,445 are already running Airflow 3 1,351 say they often use AI tools to write Airflow code Those last two numbers together are part of why this example exists: the people most likely to use th

### AI overview

Streamdown 2.5 is a React component library release for rendering streaming Markdown in AI-powered applications. It adds inline KaTeX support, staggered streaming animations, improved code-block rendering, CSV encoding fixes for Excel on Windows, and better Tailwind CSS v3 compatibility.

### Source excerpt

Streamdown is a React component library that makes rendering streaming markdown content easy and beautiful. Built for AI-powered applications, it handles the unique challenges that arise when markdown is tokenized and streamed in real time. v2.5 adds inline KaTeX support, staggered streaming animations, and a round of fixes for code blocks, CSV exports, and better Tailwind v3 compatibility. Streaming parser improvements The new inlineKatex option auto-completes $formula to $formula$ during streaming, avoiding ambiguity with currency symbols, and the option defaults to false. Block KaTeX completion is also fixed when streaming produces a partial closing $. Separately, single ~ between word characters (e.g. 20~25°C) is now escaped to prevent false strikethrough rendering, controlled via a new singleTilde option that is enabled by default. Staggered streaming animations Streaming word and character animations now cascade sequentially rather than animating all at once. The timing is configurable via a new stagger option (default 40ms). Set stagger: 0 to restore the previous behavior. Code blocks Custom renderers now receive the raw metastring from the code fence via a new optional meta prop, and the lineNumbers prop lets you disable line numbers. Long lines now scroll horizontally instead of being clipped, completed blocks no longer re-render when new streaming content arrives, and unknown or truncated language identifiers fall back to plain text highlighting instead of throwing an error. Bug fixes save() now prepends a UTF-8 BOM for text/csv content, so Excel on Windows correctly detects encoding. Tailwind v4-only *:last: / *:first: syntax is replaced with arbitrary variant equivalents, fixing caret rendering in Tailwind CSS v3. Read the documentation to get started. Read more

### AI overview

DigitalOcean introduces a custom date range billing view that lets customers analyze cloud spending over specific periods, with daily, weekly, and monthly breakdowns by product. The feature is available globally through the Billing Console, Cloud Console, and API, with CSV report downloads.

### Source excerpt

If you've ever stared at an unexpected cloud bill spike and sifted through invoices trying to find the cause, you know how time-consuming cost investigations can be. Until now, identifying cost anomalies often meant waiting for your monthly invoice or manually calculating month-to-date usage. That changes today. All DigitalOcean customers now have access to the new custom date range billing view. This new feature is accessible in the Billing Console by going to Billing -> Insights. Additionally, you can download your report as a CSV so you can view your granular billing insights offline. What's included in this new feature This update gives you clearer, more granular visibility into your cloud costs (segmented into daily, weekly, and monthly spend by product) making budgeting and forecasting far easier. DevOps, Finance, and growing teams can now manage spend proactively instead of reacting after the fact. For all customers, this feature is available globally and fully self-service via the Cloud Console and API. Here is a close look into the features of this new billing view: Custom date range filtering: You are no longer limited to invoices for viewing your spending. Choose any start and end date to view total spend for that exact range. This makes it easy to align cloud costs with development sprints, project timelines, or product launches-and improves internal chargebacks and budgeting accuracy. Daily spend breakdown: Daily granularity is key for surfacing anomalies. Instead of a single aggregated number, you can see how your spend changes day by day. If a deployment three weeks ago caused a spike, you can pinpoint the exact day and correlate it with logs to find the root cause quickly. Cost by product breakdown: See exactly where your money is going with a breakdown of spend across services such as: Droplets Databases Spaces Bandwidth Financial adjustments at a glance: For organization-level reporting, the total costs now clearly include financial adjustments like

### AI overview

The article describes a project to estimate commute times from Warsaw addresses to Metro Świętokrzyska using public transit and car travel. It uses Warsaw address data, Google Distance API, and a SQLite3 database, but the author collected data for only about 4% of the records after exhausting the API's free plan.

### Source excerpt

Location, location, location! That's what the real estate agent will tell you when asked what's the most important factor when choosing the place to live. When living in a modern, busy city like Warsaw you have two choices: traveling by car or by public transit. I came up with the idea to automate finding the best place to live in Warsaw, transport-wise. My plan is to estimate the time it takes to commute from every address in Warsaw to the city center. I'm focusing on public transport and I'd like to find both hidden gems and transport black holes. That is, places with great commute time despite the distance and the opposite - respectively.
