Its example builds a NetBox MCP with read/write access, excludes DELETE endpoints, and caches the schema. ### Source excerpt MCP has gained a huge amount of popularity. And for good reason, it's easy to use and can allow you to really harness the benefits of LLMs. So here's a quick MCP tip! Dynamically create MCP servers with FastMCP by passing a REST API's ## The Data Structures Behind Text Editors: Gap Buffers, Piece Tables, Ropes, and CRDTs DevFeed: [The Data Structures Behind Text Editors: Gap Buffers, Piece Tables, Ropes, and CRDTs]() Original publisher: [Read original article]() Published: 2026-04-05T00:00:00Z Content type: tutorial Language: en Sources: [Gaurav Sarma's Blog]() Topics: [Data structures](), [distributed-systems]() Tags: [data-structures](), [delete](), [distributed-systems](), [editor](), [file](), [insert](), [memory](), [search](), [syntax-highlighting]() ### AI overview This tutorial explains how text editors represent document buffers in memory. It compares gap buffers, piece tables, ropes, and CRDTs, focusing on the trade-offs among insertion, deletion, reading, cursor movement, memory efficiency, latency, and multi-user concurrency. ### Source excerpt Open a text editor, type a character, and it appears on screen. That single keystroke triggers a surprisingly deep question: how does the editor represent your document in memory so that insertions, deletions, and cursor movements all feel instant, even on a file with millions of lines... ## PostgreSQL temporal UPDATE and DELETE by range DevFeed: [PostgreSQL temporal UPDATE and DELETE by range]() Original publisher: [Read original article]() Author: depesz Published: 2026-04-02T10:51:21Z Content type: tutorial Language: en Sources: [select \* from depesz;]() Topics: [PostgreSQL](), [postgresql 18]() Tags: [delete](), [period](), [pg19](), [postgresql](), [query](), [range](), [temporal](), [uncategorized](), [update](), [version](), [waiting]() ### AI overview This article explains a PostgreSQL patch that extends UPDATE and DELETE for temporal tables, allowing changes or deletions over a specified range or multirange period. The article also notes that the patch was later reverted after discussion. ### Source excerpt Important update This has been reverted with some discussion. Thanks for ping to mkurz 🙂 On 1st of April 2026, Peter Eisentraut committed patch: Add UPDATE/DELETE FOR PORTION OF This is an extension of the UPDATE and DELETE commands to do a "temporal update/delete" based on a range or multirange column. The user can ... Continue reading "Waiting for PostgreSQL 19 - Add UPDATE/DELETE FOR PORTION OF" ## What is index overhead on writes? DevFeed: [What is index overhead on writes?]() Original publisher: [Read original article]() Author: depesz Published: 2026-01-06T11:57:10Z Content type: article Language: en Sources: [select \* from depesz;]() Topics: [data]() Tags: [benchmark](), [btree](), [delete](), [gin](), [index](), [insert](), [operations](), [overhead](), [performance](), [postgresql](), [speed](), [tutorial](), [uncategorized](), [update]() ### AI overview The article measures how indexes affect write performance using PostgreSQL 18 and a one-million-row test table. It reports that loading performance decreases as indexes are added, and that a roughly 3.6-fold increase in storage corresponded to an eightfold slowdown in the tested case. A single wide index performed better than ten separate indexes, though the author notes that the configurations solve different computational problems. ### Source excerpt One of things people learn is that adding indexes isn't free. All write operations (insert, update, delete) will be slower - well, they have to update index. But realistically - how much slower? Full tests should involve lots of operations, on realistic data, but I just wanted to see some basic info. So I figured ...

It describes correlated-subquery emulation, DML JOIN support for selected RDBMS, and planned translation using updatable views in Oracle. ### Source excerpt Since jOOQ 3.11, implicit joins have been supported. An implicit join is a JOIN (mostly a LEFT JOIN) that is generated implicitly because of the presence of a path expression. If SQL supported the syntax natively, it would look like this: All that is is convenience for a bunch of explicitly written LEFT JOIN expressions: ...

It describes using londiste handlers to process batches of replication events, including bulk-loading methods for inserting, updating, and deleting data. ### Source excerpt In the previous article here we talked about how to properly update more than one row at a time, under the title Batch Update. We did consider performances, including network round trips, and did look at the behavior of our results when used concurrently. A case where we want to apply the previous article approach is when replicating data with a trigger based solution, such as SkyTools and londiste. Well, maybe not in all cases, we need to have a amount of UPDATE trafic worthy of setting up the solution. As soon as we know we're getting to replay important enough batches of events, though, certainly using the batch update tricks makes sense. ## Xen - Podstawowe polecenia DevFeed: [Xen - Podstawowe polecenia]() Original publisher: [Read original article]() Author: Tom Published: 2012-06-19T00:00:00Z Content type: tutorial Language: pl Sources: [Tomasz Gągor]() Topics: [Xen](), [LVM]() Tags: [bridge](), [create](), [delete](), [domain](), [example](), [gateway](), [howto](), [image](), [ip](), [lvm](), [memory](), [os](), [power](), [tools](), [uptime](), [xen]() ### AI overview A Polish tutorial explains basic Xen commands for creating and deleting virtual machines and for managing their lifecycle, including listing, starting, shutting down, resetting, restarting, pausing, and monitoring resource usage. It also demonstrates Xen configuration involving LVM volumes and network settings. ### Source excerpt Pisałem już HOWTO o konfiguracji Xen'a ale nie opisałem jak się bawić wirtualkami gdy Xen'a już mamy. To nadrabiam. Tworzenie i usuwanie maszyn wirtualnych Do tworzenia/niszczenia DomU wykorzystuję pakiet xen-tools dostarczający m.in. dwa narzędzia: xen-create - dla którego przygotowałem dość skomplikowaną konfigurację przy okazji wcześniejszego posta: Instalacja i konfiguracja DomU external link .
