SimPE for Mac

Yeah, I have not been posting lately because I am spending 8 to 12 hours a day, every day, working on a Mac version of SimPE. I made Xcode cough up a lung trying to use it on SimPE. SimPE is just too big and too complex. I am now programming on VS Code, which is far more robust, and has a far pickier compiler, so I spent days fixing all of the new compiler errors to get back to a working core. Right now it opens a package file and extracts the contents. It identifies the file types. Thanks, Quaxi, for creating the xml file listing all 145 file types the Sims 2 uses! Next up is getting it to display the actual filenames. My ancient programming skills from 20+ years ago are slowly resurrecting. It is slow going. I will be going at this for months. I may never reach full SimPE functionality, but if I can get recoloring and Sims editing to work it will be better than the nothing that Mac users currently have. The bad news is that I am building for MacOS 12 and later, so older Macs may not run it.

Wish me well in this endeavor!

カーパシー氏は、ソフトウェアというものが過去2回にわたって急速に変化したものと考えています。最初に登場したのがソフトウェア 1.0です。ソフトウェア1.0は誰もがイメージするような基本的なソフトウェアのことです。 ソフトウェア1.0がコンピュータ向けに書くコードであるのに対し、ソフトウェア2.0は基本的にニューラルネットワークであり、特に「重み」のことを指します。開発者はコードを直接書くのではなく、データセットを調整し、最適化アルゴリズムを実行してこのニューラルネットワークのパラメーターを生成するのです。 ソフトウェア 1.0に当たるGitHub上のプロジェクトは、それぞれを集約して関係のあるプロジェクトを線で結んだ「Map of GitHub」で表せます。 ソフトウェア 2.0は同様に「Model Atlas」で表されます。巨大な円の中心にOpenAIやMetaのベースとなるモデルが存在し、そのフォークがつながっています。 生成AIが洗練されるにつれ、ニューラルネットワークの調整すらAIの助けを得て行えるようになりました。これらは専門的なプログラミング言語ではなく、「自然言語」で実行できるのが特徴です。自然言語、特に英語で大規模言語モデル(LLM)をプログラミング可能になった状態を、カーパシー氏は「ソフトウェア 3.0」と呼んでいます。 まとめると、コードでコンピューターをプログラムするのがソフトウェア 1.0、重みでニューラルネットワークをプログラムするのがソフトウェア 2.0、自然言語のプロンプトでLLMをプログラムするのがソフトウェア 3.0です。 カーパシー氏は「おそらくGitHubのコードはもはや単なるコードではなく、コードと英語が混在した新しい種類のコードのカテゴリーが拡大していると思います。これは単に新しいプログラミングパラダイムであるだけでなく、私たちの母国語である英語でプログラミングしている点も驚くべきことです。私たちは3つの完全に異なるプログラミングパラダイムを有しており、業界に参入するならば、これらすべてに精通していることが非常に重要です。なぜなら、それぞれに微妙な長所と短所があり、特定の機能は1.0や2.0、3.0でプログラミングする必要があるかもしれません。ニューラルネットワークをトレーニングするべきか、LLMにプロンプトを送信するべきか。指示は明示的なコードであるべきでしょうか？つまり、私たちは皆、こうした決定を下し、実際にこれらのパラダイム間を流動的に移行できる可能性を秘めているのです」と述べました。 ◆AIは「電気」である カーパシー氏は「AIは新しい電気である」と捉えています。OpenAI、Google、Anthropic などのLLMラボはトレーニングのために設備投資を行っていて、これは電気のグリッドを構築することとよく似ています。企業はAPIを通じてAIを提供するための運用コストもかかります。通常、100万件など一定単位ごとに料金を請求する仕組みです。このAPIには、低遅延、高稼働率、安定した品質などさまざまなバリューがあります。これらの点に加え、過去に多くのLLMがダウンした影響で人々が作業不能に陥った現象も鑑みると、AIは電気のようななくてはならないインフラに当たるというのがカーパシー氏の考えです。 しかし、LLMは単なる電気や水のようなものではなく、もっと複雑なエコシステムが構築されています。OSだとWindowsやMacのようなクローズドソースのプロバイダーがいくつかあり、Linuxのようなオープンソースの代替案があります。LLMにおいても同様の構造が形成されつつあり、クローズドソースのプロバイダーが競合している中、LlamaのようなオープンソースがLLM界におけるLinuxのようなものへと成長するかもしれません。 カーパシー氏は「LLMは新しい種類のOSのようなものだと感じました。CPUの役割を果たすような存在で、LLMが処理できるトークンの長さ(コンテキストウィンドウ)はメモリに相当し、メモリと計算リソースを調整して問題解決を行うのです。これらの機能をすべて活用しているため、客観的に見ると、まさにOSに非常に似ています。OSだとソフトウェアをダウンロードして実行できますが、LLMでも同様の操作ができるものもあります」と述べました。 ◆AIは発展途中 LLMの計算リソースはコンピューターにとってまだ非常に高価であり、性能の良いLLMはほとんどクラウドサーバーで動作しています。ローカルで実行できるDeepSeek-R1のようなモデルも出てきていますが、やはり何百万円もするような機器を何百台とつなげて動かしているようなクラウドサーバーと個人のPCでは出力結果に大きな差が現れます。 カーパシー氏は「個人用コンピューター革命はまだ起こっていません。経済的ではないからです。意味がありません。しかし、一部の人々は試みているかもしれません。例えば、Mac miniは一部のLLMに非常に適しています。将来的にどのような形になるかは不明です。もしかしたら、皆さんがこの形や仕組みを発明するかもしれません」と述べました。 また、PCでは当たり前に使われているグラフィカルユーザーインターフェース(GUI)がLLMには中途半端にし��導入されていないという点も特徴です。ChatGPTなどのチャットボットは、基本的にテキスト入力欄を提供しているだけです。カーパシー氏は「まだ一般的な意味でのGUIが発明されていないと思います」と話しています。 ◆AIは技術拡散の方向が逆 これまでのPCは、政府が軍事用に開発し、企業などがそれを利用し、その後広くユーザーに使われるという歴史をたどってきました。一方でAIは政府や企業ではなくユーザーが広く利用し、その集合知が体系化され、企業が利用するようになります。カーパシー氏は「実際、企業や政府は、私たちが技術を採用するような速度に追いついていません。これは逆行していると言えるでしょう。新しい点であり前例がないといえるのは、LLMが少数の人々や企業の手中にあるのではなく、私たち全員の手中にあることです。なぜなら、私たちは皆コンピュータを持っており、それはすべてソフトウェアであり、ChatGPTは数十億の人々に瞬時に、一夜にしてコンピュータに配信されたからです。これは信じられないことです」と語りました。 ◆人類はAIと協力関係にある AIが利用されるときは、通常、AIが生成を行い、人間である私たちが検証を行うという作業が繰り返されます。このループをできるだけ高速化することは人間にとってもAIにとってもメリットがあります。 これを実現する方法としてカーパシー氏が挙げるのが、1つは検証を大幅にスピードアップすることです。これはGUIを導入することで実現できる可能性があります。長いテキストだけを読むことは労力がかかりますが、絵など文字以外の物を見ることで容易になります。 2つ目は、AIを制御下に置く必要がある点です。カーパシー氏は「多くの人々がAIエージェントに過剰に興奮している」と指摘しており、AIの出力すべてを信じるのではなく、AIが正しいことを行っているか、セキュリティ上の問題がないかなどを確かめることが重要だと述べています。LLMは基本的にもっともらしい言葉をもっともらしく並べるだけの機械であり、出力結果が必ずしも正しいとは限りません。結果を常に検証することが大切です。 この記事のタイトルとURLをコピーする ・関連記事 Metaが既存の生成AIにあるトークン制限をはるかに上回る100万トークン超のコンテンツ生成を可能にする次世代AIアーキテクチャ「Megabyte」を発表 - GIGAZINE 世界最長のコンテキストウィンドウ100万トークン入力・8万トークン出力対応にもかかわらずたった7800万円でトレーニングされたAIモデル「MiniMax-M1」がオープンソースで公開され誰でもダウンロード可能に - GIGAZINE AppleがXcodeにAIでのコーディング補助機能を追加＆Apple Intelligenceの基盤モデルフレームワークが利用可能に - GIGAZINE AnthropicがAIモデルの思考内容を可視化できるオープンソースツール「circuit-tracer」を公開 - GIGAZINE DeepSeek��清華大学の研究者がLLMの推論能力を強化する新しい手法を発表 - GIGAZINE 「現在のAIをスケールアップしても汎用人工知能は開発できない」と考える科学者の割合は76％ - GIGAZINE ・関連コンテンツ TwitterやFacebookで使われている「Apache Hadoop」のメリットや歴史を作者自らが語る 仮想通貨暴落などで苦境に立たされたマイニング業者は余ったGPUを「AIトレーニング用のリソース」として提供している 「AI懐疑論者の友人はみんな頭がおかしい」というブログが登場、賛否両論さまざまなコメントが寄せられる 私たちが何気なく使っているソフトウェアはどのように開発されているのか？ グラフをはみ出した点と線が世界に広がっていく手描きアニメ「Extrapolate」が圧巻 「アルゴリズムって何？」を専門家が分かりやすく解説 機械学習でコンピューターが音楽を理解することが容易ではない理由 生きてるだけでお金がもらえるベーシックインカムこそ「資本主義2.0」だとの主張、その理由とは？

Key Skills to Look for When Hiring Offshore iOS Developers

Hiring the right talent is crucial when building high-quality iOS apps. Many companies turn to Offshore iOS Developers to cut costs while maintaining productivity and quality. However, not every developer is a perfect fit. To ensure success, you need to identify precisely the skills to look for.

In this article, we'll explore the key skills that every company should consider when hiring offshore iOS developers.

1. Proficiency in Swift and Objective-C

The foundation of any iOS app is built using Swift or Objective-C. While Swift is the more modern language, many legacy projects still use Objective-C. A skilled offshore iOS developer should be fluent in both, or at the very least, highly proficient in Swift.

Tip: Ask for code samples or conduct a small coding test to evaluate language skills.

2. Experience with iOS Frameworks and APIs

Look for developers who are familiar with the Core iOS frameworks, such as:

UIKit

CoreData

AVFoundation

CoreAnimation

CoreLocation

They should also be able to integrate third-party APIs and SDKs seamlessly, which is a common need in modern app development.

3. Knowledge of Apple’s Human Interface Guidelines

Design is just as important as functionality. Offshore iOS developers must understand and follow Apple's Human Interface Guidelines (HIG) to ensure their apps look and feel right on all Apple devices.

Why it matters: Apps that don't follow HIG risk being rejected by the App Store.

4. Problem-Solving and Debugging Skills

Bugs and issues are inevitable in any development project. Skilled offshore developers must be capable of debugging quickly and effectively using tools like:

Xcode Debugger

Instruments

Crashlytics

5. Version Control with Git

Collaboration is essential when working with remote teams. Offshore iOS developers should be experienced in using Git and platforms like GitHub or Bitbucket for version control. This ensures clean code management and easy collaboration with your in-house team.

6. Unit Testing and Code Quality

High-quality code means fewer issues in production. Developers should be able to write unit tests using tools like XCTest or Quick/Nimble. Testing ensures the code is stable and maintains long-term reliability.

7. Communication and Collaboration Skills

One of the most overlooked yet essential skills is effective communication. Offshore teams work in different time zones, so it's vital that developers can clearly share updates, ask questions, and participate in virtual meetings using tools like Slack, Zoom, or Jira.

8. Understanding of RESTful APIs and JSON

Most apps interact with web services. Offshore iOS developers should have experience in consuming RESTful APIs, parsing JSON data, and handling network responses gracefully.

9. Adaptability to Agile Methodologies

Many businesses operate using Agile or Scrum methodologies. A good offshore developer should be familiar with sprints, stand-ups, and backlog grooming and be able to work in a fast-paced, iterative environment.

10. Portfolio and Previous Projects

Always review the developer’s past work. A strong portfolio of iOS apps available on the App Store is a good indicator of real-world experience and capability.

Bonus Tip: Reach out to previous clients or employers to verify performance and reliability.

Final Thoughts

Hiring Offshore iOS Developers can bring significant value to your business, but only if you focus on the right skills. From technical expertise to communication and problem-solving abilities, each of the skills listed above plays a crucial role in building successful iOS applications.

By thoroughly screening and identifying these key capabilities, you'll be well on your way to building a productive and reliable offshore iOS development team.

Apply performance monitoring during exploratory and automated test runs.

5. Interruptions and Background Activities

🔍 Challenge:

Incoming calls, messages, app switching, and screen locks can disrupt app performance.

✅ Solution:

Use Appium or Espresso to script interruption scenarios.

Test app state persistence (resume, restart, background recovery).

Simulate push notifications, call interruptions, or multi-tasking scenarios.

6. Security and Data Privacy

🔍 Challenge:

Mobile apps often handle sensitive data (e.g., user location, payment info) and are prone to vulnerabilities.

✅ Solution:

Conduct security testing using tools like MobSF, OWASP ZAP, and Burp Suite.

Implement encryption, secure APIs, and proper permission handling.

Follow OWASP Mobile Top 10 guidelines.

7. App Store Guidelines & Compliance

🔍 Challenge:

Failing to comply with Google Play or Apple App Store requirements can result in rejections or delays in release.

✅ Solution:

Ensure thorough pre-submission testing including permissions, ads, privacy policies, and crashes.

Validate in-app purchase flows, third-party SDK usage, and UI/UX alignment with platform guidelines.

Use tools like TestFlight (iOS) and Internal App Sharing (Android) for pre-release testing.

8. Test Automation Complexity

🔍 Challenge:

Mobile automation is harder due to device interaction, gestures, and native/web hybrid app structures.

✅ Solution:

Use cross-platform tools like Appium, Detox, XCUITest, or Espresso based on your tech stack.

Maintain modular test architecture to adapt to UI changes.

Implement CI/CD pipelines using Bitrise, CircleCI, or Jenkins for continuous feedback.

9. UI Consistency Across Devices

🔍 Challenge:

Same UI can render differently across screens, DPIs, and orientations.

✅ Solution:

Use visual regression testing tools like Applitools, Percy, or Screener.

Automate UI layout checks under different resolutions and themes (dark/light).

Leverage responsive UI design principles from development stage onward.

10. Real-User Conditions & Feedback

🔍 Challenge:

Lab-based testing often misses real-world user behaviors or edge-case scenarios.

✅ Solution:

Use beta testing platforms like Firebase App Distribution or TestFlight to gather real-user feedback.

Implement crash reporting with tools like Crashlytics, Instabug, or Sentry.

Continuously analyze user session data, heatmaps, and logs for behavioral insights.

How to Create Your Own App in 2025: A Beginner’s Step-by-Step Guide

In today’s digital era, apps are not just for tech giants or professional developers. Whether you're a small business owner, a student with a great idea, or a creative mind exploring new horizons, 2025 is the best time to learn how to create your own app — even if you don’t know how to code. Thanks to powerful and user-friendly tools, creating a mobile app is more accessible than ever.

This blog walks you through every essential step, from concept to launch, in a simple and beginner-friendly way.

Step 1: Start with a Clear Idea

Every great app starts with a strong idea. Take time to define:

What your app does

Who it helps

What problem it solves

Your idea should be simple and focused. For instance, a task reminder app, a food ordering service for your area, or an app that helps students manage study schedules. Write your thoughts on paper or use a mind-mapping tool to organize them.

Step 2: Do Market Research

Once you have your idea, look around to see if similar apps already exist. Analyze:

What features those apps offer

How users have rated them

What users complain about

This step helps you understand where you can improve or stand out. Tools like Google Trends, App Store reviews, and user forums can offer helpful insights.

Step 3: Define the Core Features

As a beginner, it’s better to focus on building an MVP — a Minimum Viable Product. List the features your app must have in its first version.

For example, if you’re making a recipe app, your MVP could include:

Recipe categories

Search function

Save favorite recipes

Share via social media

Avoid adding too many complex features in the beginning. You can always update the app later based on user feedback.

Step 4: Choose an App Builder Tool

You don’t need to be a software engineer to build an app today. Many no-code or low-code platforms let beginners create apps without writing a single line of code.

Popular tools in 2025 include:

Thunkable: Ideal for Android and iOS, easy drag-and-drop interface.

Adalo: Great for building native mobile apps visually.

Glide: Turns your Google Sheets into mobile apps quickly.

FlutterFlow: Best for those looking for more customization with low-code options.

These platforms offer templates, component libraries, and step-by-step guidance to make your job easier.

Step 5: Design Your App

Good design matters as much as functionality. Start by creating wireframes (basic screen layouts) using tools like:

Figma

Canva (mobile templates)

Adobe XD

Keep your user interface clean and intuitive. Choose fonts, icons, and colors that match your app’s purpose. For example, use soft colors for a meditation app, or bold tones for a fitness tracker.

Step 6: Start Building the App

Now it's time to bring your design to life. Use your chosen platform to:

Add pages/screens

Insert buttons, images, and text

Link the screens for smooth navigation

Connect to a database if your app needs to store user data

Most app builders have preview options so you can test the look and feel of your app as you build it.

Step 7: Test Your App

Before launching, test your app thoroughly. Check how it performs on different devices, screen sizes, and internet connections. Ask a few friends or family members to try it and provide feedback.

Focus on:

Usability

Navigation

Speed and loading time

Any bugs or glitches

Make necessary adjustments to enhance the user experience.

Step 8: Publish Your App

When you're satisfied with your app, you can publish it to app stores:

For Android:

Create a Google Play Developer account ($25 one-time fee)

Upload the APK file

Add descriptions, screenshots, and submit for review

For iOS:

Join the Apple Developer Program ($99/year)

Use Xcode or app builder integrations to submit the app

Complete the App Store checklist and publish

App review and approval may take a few days, depending on guidelines and content.

Step 9: Promote Your App

Once live, your app needs users. Start promoting using:

Social media platforms (Instagram, LinkedIn, Twitter)

Blog posts and SEO (like this one!)

App Store Optimization (ASO)

Paid ads (Google Ads, Meta Ads)

Word-of-mouth marketing

Create engaging content around your app’s features and benefits to attract attention and build credibility.

Step 10: Keep Improving Based on Feedback

Your first version isn’t the end — it’s the beginning. Listen to your users. Add features they request, fix bugs, and keep enhancing the app. Regular updates not only keep users happy but also help with app ranking on stores.

Final Thoughts

Learning how to create your own app in 2025 is a powerful skill that opens doors to entrepreneurship, innovation, and financial growth. You don’t need to be a tech expert. With the right idea, smart planning, and easy-to-use tools, you can launch your app and start making a difference.

So, what are you waiting for? Start building your app today — your future self will thank you.
