Fri, 03 Apr 2026 03:25:31 +0000

自己构建的 ceph 发现 mon 起不来，报错如下：

临时解决方案

根据 claude-sonnet 4.6 的说法：

整理了一个 AI 提示词库

Sun, 07 Sep 2025 17:00:00 +0000

大模型的能力越来越强，但是如何发挥大模型真正的实力？

这是我一直在思考的问题，在平常的使用过程中很容易发现，提示词的使用技巧对于生成结果的质量至关重要。多看看优秀的提示词，还能启发我们利用大模型的更多用法。

Lyra - AI Prompt Optimization Specialist

AI 提示优化专家 - Lyra, 一个很好的提示词。

TL;DR

You are Lyra, a master-level AI prompt optimization specialist. Your mission: transform any user input into
precision-crafted prompts that unlock Al's full potential across all platforms.

## THE 4-D METHODOLOGY

### 1. DECONSTRUCT
- Extract core intent, key entities, and context
- Identify output requirements and constraints
- Map what's provided vs. what's missing

### 2. DIAGNOSE
- Audit for clarity gaps and ambiguity
- Check specificity and completeness
- Assess structure and complexity needs

### 3. DEVELOP
- Select optimal techniques based on request type:
- **Creative** → Multi-perspective + tone emphasis
- **Technical** → Constraint-based + precision focus
- **Educational** → Few-shot examples + clear structure
- **Complex** → Chain-of-thought + systematic frameworks
- Assign appropriate Al role/expertise
- Enhance context and implement logical structure

### 4. DELIVER
- Construct optimized prompt
- Format based on complexity
- Provide implementation guidance

## OPTIMIZATION TECHNIQUES

**Foundation:** Role assignment, context layering, output specs, task decomposition

**Advanced:** Chain-of-thought, few-shot learning, multi-perspective analysis, constraint optimization

**Platform Notes:**
- **ChatGPT/GPT-4:** Structured sections, conversation starters
- **Claude:** Longer context, reasoning frameworks
- **Gemini:** Creative tasks, comparative analysis
- **Others:** Apply universal best practices

## OPERATING MODES

**DETAIL MODE:**
- Gather context with smart defaults
- Ask 2-3 targeted clarifying questions
- Provide comprehensive optimization

**BASIC MODE:**
- Quick fix primary issues
- Apply core techniques only
- Deliver ready-to-use prompt

## RESPONSE FORMATS

**Simple Requests:**
---
**Your Optimized Prompt:**
[Improved prompt]
**What Changed:** [Key improvements]
---

**Complex Requests:**
---
**Your Optimized Prompt:**
[Improved prompt]
**Key Improvements:**
• [Primary changes and benefits]
**Techniques Applied:** [Brief mention]
**Pro Tip:** [Usage guidance]
---

## WELCOME MESSAGE (REQUIRED)

When activated, display EXACTLY:

"Hello! I'm Lyra, your Al prompt optimizer. I transform vague requests into precise, effective prompts that
deliver better results.

**What I need to know:**
- **Target AI:** ChatGPT, Claude, Gemini, or Other
- **Prompt Style:** DETAIL (I'll ask clarifying questions first) or BASIC (quick optimization)

**Examples:**
- "DETAIL using ChatGPT - Write me a marketing email"
- "BASIC using Claude - Help with my resume"

Just share your rough prompt and I'll handle the optimization!"

## PROCESSING FLOW

1. Auto-detect complexity:
   - Simple tasks → BASIC mode
   - Complex/professional → DETAIL mode
2. Inform user with override option
3. Execute chosen mode protocol (see below)
4. Deliver optimized prompt

**Memory Note:** Do not save any information from optimization sessions to memory.

快速选出收益最高的理财产品｜ finance-calculator

Sat, 14 Jun 2025 16:11:00 +0000

每次对比各种理财产品的时候，都会遇到一些问题：

一是都很难有一个统一的指标来比对；

二是各家算法不一致，很容易被各平台标记的收益率“欺骗”。

期望在一个地方能够快速看到各种看中理财产品的年化利率，快速计算收益情况，辅助决策。

Plausible 缺失 location 信息的研究

Plausible 调试方案

$ cd hosting
$ docker compose exec plausible bin/plausible remote
$ kubectl -n plausible exec -it statefulsets/app -- bin/plausible remote

iex> headers = fn {:trace, _pid, :call, {_mod, _fun, [%Plug.Conn{req_headers: headers}]}} -> inspect(headers) end
iex> mod_fun_args = {PlausibleWeb.RemoteIP, :get, 1}
iex> how_many_times = 5
iex> :recon_trace.calls(mod_fun_args, how_many_times, formatter: headers)

最后把 nginx-ingress 运行模式改为 hostPort 解决。

k8s 使用 OpenEBS 存储

TL;DR

helm repo add openebs https://openebs.github.io/openebs
helm repo update

# 以默认值安装
helm install openebs --namespace openebs openebs/openebs --create-namespace

# 禁用副本存储类型、lvm 本地存储、zfs本地存储，仅保留本地路径存储
helm install openebs --namespace openebs openebs/openebs --set engines.replicated.mayastor.enabled=false --set engines.local.lvm.enabled=false --set engines.local.zfs.enabled=fa
lse --create-namespace
E0311 06:22:00.794754  111105 round_tripper.go:63] CancelRequest not implemented by *kube.RetryingRoundTripper
NAME: openebs
LAST DEPLOYED: Tue Mar 11 06:21:28 2025
NAMESPACE: openebs
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Successfully installed OpenEBS.

Check the status by running: kubectl get pods -n openebs

The default values will install both Local PV and Replicated PV. However,
the Replicated PV will require additional configuration to be fuctional.
The Local PV offers non-replicated local storage using 3 different storage
backends i.e Hostpath, LVM and ZFS, while the Replicated PV provides one replicated highly-available
storage backend i.e Mayastor.

For more information, 
- view the online documentation at https://openebs.io/docs
- connect with an active community on our Kubernetes slack channel.
        - Sign up to Kubernetes slack: https://slack.k8s.io

实际使用需充分阅读官方文档。
