A 200 GB disk, and df -h said only 54 GB was left — 72% used. Most days that is survivable. But this machine also runs a small Kubernetes cluster, and the moment an image pull or a build needs a few GB of scratch space, “three-quarters full” stops being a comfortable place to be. This is the write-up of two things: where the space actually went, and — the more important half — how I convinced myself that deleting it did not break anything that was running. ...
Pod Restarted 15 Times: How a Podman Bridge Triggered a microk8s Certificate Rotation
A small app of mine had been running quietly for months. Then one day, it showed: 15 restarts. The only log it produced was two lines: 1 2 3 4 Error: timed out Caused by: timed out The strange part: every other pod in the same cluster had restarted exactly 6 times. Same node, same moment — why did only this one crash 9 extra times? The answer turned out to be two problems stacked on top of each other. One was cluster-wide: all pods were being killed together. The other was app-level: only my app turned a brief dependency hiccup into a crash loop. ...
IELTS General Training — Day 15 Coaching Log
Day 15 — IELTS Training Journal Focus: Vocabulary → Reading → Light Writing Training status: Completed 1. Day 15 Objectives The main objective of Day 15 was to continue shifting from vocabulary recognition toward active vocabulary control, then apply that vocabulary in IELTS Reading and light Writing. Today’s sequence was: Vocabulary active recall and word formation Vocabulary sentence production IELTS-style Reading comprehension Reading inference/paraphrase challenge Light IELTS Writing Detailed review and correction A deliberate decision was made not to spend excessive time on formal writing-error classification. The focus remained on how to correct and reuse the language effectively. ...
IELTS General Training — Day 14 Coaching Log
Day 14 — IELTS General Training Journal 1. Session focus Day 14 continued the IELTS General Training preparation with emphasis on: vocabulary retrieval and contextual use; reading comprehension; Matching Headings strategy; True / False / Not Given discipline; vocabulary in context; Light Writing; grammar and collocation correction; distinguishing vocabulary knowledge from actual word-use knowledge. A major coaching adjustment was also made today: the training should remain explicitly IELTS General Training (GT) rather than being framed as Academic IELTS preparation. Broader and unfamiliar reading material can still be used to strengthen general reading ability, but the target exam remains GT. ...
IELTS General Training — Day 13 Coaching Log
Day 13 Journal — IELTS General Training Preparation Focus: Vocabulary → Reading → Light Writing Primary objective: Continue strengthening vocabulary while moving from isolated lexical knowledge into contextual reading and active written production. Reading practice was corrected during the session to align with IELTS General Training (GT) rather than Academic IELTS. 1. Session Opening The session began with a plan to continue the previous training sequence, prioritising vocabulary, then reading, then writing. ...
IELTS General Training — Day 12 Coaching Log
1. Overview Day 12 focused on three major areas: Vocabulary — moving from basic recognition toward C1/C2-level lexical precision and active usage. Reading — testing comprehension of academic texts, especially main ideas, paraphrasing, inference, and authorial stance. Grammar — maintaining accuracy through verb-complement patterns and controlled production. Light Writing — applying the day’s vocabulary and grammar in a short IELTS-style response. A major conclusion from today’s training is that my receptive English is currently stronger than my productive English. I can understand sophisticated academic material quite well, but when I produce advanced vocabulary myself, I sometimes choose a word from the correct semantic neighborhood without using the most natural collocation or grammatical pattern. ...
IELTS General Training — Day 11 Coaching Log
Today’s Focus IELTS Reading comprehension Vocabulary from context Paraphrase recognition Inference TRUE / FALSE / NOT GIVEN reasoning Distinguishing textual evidence from unsupported assumptions 1. First IELTS-Style Reading Passage The changing role of public libraries For much of the twentieth century, public libraries were primarily regarded as places where people could access printed books and other physical materials. Their role was relatively straightforward: they provided resources that individuals might not be able to afford themselves. However, the rapid development of digital technology has fundamentally altered this function. With enormous quantities of information now available online, libraries can no longer justify their existence simply by providing access to printed material. ...

IELTS General Training — Day 10 Coaching Log
1. Context Days 8 and 9 locked Priority 1 (singular subject + -s) and Priority 2 (articles a/the/Ø). Day 10 targets Priority 3: due to / because of / because — the third recurring Week 1 register trap (“due to it gives one great freedom” was wrong because due to must follow a noun / form of be, not a clause). Rule taught: because → followed by a clause (subject + verb) because of → followed by a noun phrase due to → follows a form of be, or a noun; means “caused by”; it does NOT start a sentence as a reason clause. 2. The Main Drill (10 sentences) Coach instruction: fill each gap with because / because of / due to. ...
IELTS General Training — Day 8 Coaching Log
1. Context I’ve now completed one week of self-study (the Week 1 log already exists). Starting assessed level was roughly Band 6–6.5; target is Band 7.5 GT. The Week 1 coach was reactive and let the same error recur three separate times — technology make, hard working contribute, chores make. That was the core weakness: a singular subject dropping its -s on the verb. This daily coaching format is diagnostic, not a lecture series. The rule is simple: drill until the score proves the habit is locked, then advance. No fixed weekly calendar — one focused task per day. ...
