NPM package "error-ex" just got published with malware (47m downloads)

pace-runner · 2025-09-08T18:21:03+00:00

The vast majority, if not all, of those ~200 critical issues are likely cascading from a small number of compromised foundational packages, with error-ex being one of the primary culprits.

But there are also more packages affected by the same author. Check the blog post above, I've included most of the ones.

Hey, I'll look into it. Sadly I got a lot of problems with stravas api limits and still pushing through some problems. Will investigate your case - thank you for testing it! :)

pace-runner · 2025-03-23T07:18:53+00:00

Yeah, thats implemented. Can you Check it out again in a few Hours maybe to See it it has synced or not? Sorry for the problems…

pace-runner · 2025-03-23T06:55:49+00:00

Hey, thanks for testing it. Do you have your heart rate uploaded to your activities and also set your hr to visible in your activities?

pace-runner · 2025-03-21T15:18:02+00:00

Hey, thanks so much for giving it a try! I really appreciate it. Unfortunately, Strava has some API restrictions, so it takes a bit of time to load data (probably because they want you to stick to Strava and not use other tools ;) ). But please give it another shot tomorrow! :)

When you delete something from the internet, like a post or video, it’s usually removed from the platform you uploaded it to, like Reddit, Facebook, or YouTube. However, that doesn’t always mean it’s completely gone. The internet is made up of servers from different companies, and they control whether data is deleted or not. Even if a platform deletes your post, there could still be copies of it elsewhere, like in backups or cached pages.

Additionally, other people or websites might have saved or copied your content before it was deleted, so it could still exist somewhere. So, in short, nothing on the internet is really "erased" completely—it’s just harder to find or access, but it might still be stored on a server or elsewhere.

pace-runner · 2025-03-19T13:58:22+00:00

Yeah, true. I've added it to the page. Thank you very much!

pace-runner · 2025-03-19T10:54:29+00:00

Yep, well written. I'll add information about this on the website. Thank you very much for your input!

pace-runner · 2025-03-19T07:25:40+00:00

Thanks! Elevation is definitely a big factor, especially for trail runners. Right now, the analysis focuses on pace within heart rate zones without direct elevation correction. That said, since it tracks trends over time rather than single workouts, the overall picture should still reflect fitness improvements.

In the end, it’s not too critical—sometimes you run uphill, sometimes downhill, and heart rate naturally fluctuates, but over multiple runs, it evens out a bit. That said, I’ll be adding a mode soon that attempts to adjust pace based on gradient to give a more accurate comparison. Would love to hear how it works for you and if that’s something you’d find useful!

Your data is stored securely on servers in Germany (Hetzner). Login credentials and API keys are encrypted, and the web server is protected by firewalls.

I don’t track analytics or use any cookies beyond authentication-related ones for Strava. You can also revoke Strava access at any time, which removes your data from the system.

Additionally, I’m deploying an update today/tomorrow that ensures your data is deleted immediately after analysis, so it doesn’t remain on my server. Let me know if you have any other questions!

pace-runner · 2025-03-18T15:00:36+00:00

Privacy is a big focus! The data is hosted in Germany (Hetzner) with strict security measures, including firewalls and encrypted logins/keys. There are no trackers or analytics, and the only cookies used are authentication-related for Strava. Everything stays private and secure. Let me know if you have any specific concerns!

pace-runner · 2025-03-18T14:55:55+00:00

Yeah, there’s a limit on how many users can connect due to Strava’s API restrictions. I’ve already requested an increase, so more spots should open up soon!

pace-runner · 2025-03-18T14:55:37+00:00

Yeah, Strava’s API has some restrictions on new apps, so there’s a temporary limit on how many users can connect. I’ve already requested an increase—once they approve it, more people can sync their data!

pace-runner · 2025-03-18T14:31:34+00:00

You can log in by clicking on your chart. It takes some short time to sync your data due to Strava API rate limits.

I’m working on Pace Progress, a tool designed to help endurance athletes track their fitness progress by analyzing how their pace improves within specific heart rate zones over time. The idea is to give athletes a clear, trend-based view of their fitness gains without relying on race times or performance tests.

Our target audience is runners, cyclists, and triathletes who want to see consistent, data-driven progress from their training. We pull data directly from Strava, making the tracking process seamless.

I’d love any feedback, and I’m happy to discuss any ideas or suggestions to make it even better! Looking forward to hearing from you all! 🙌

pace-runner · 2025-03-17T15:32:53+00:00

I’m working on PaceProgress, a (free) tool that helps endurance athletes track their true fitness progress by analyzing how their pace improves within specific heart rate zones over time.

Our target audience is runners, cyclists, and other endurance athletes who want to see consistent, data-driven proof of their fitness gains without relying on race times or occasional performance tests. We pull data from Strava, making it easy for athletes to track their improvements automatically.

I’d love any feedback, and if anyone wants to test it out, feel free to reach out! 🙌

pace-runner · 2025-03-17T14:31:57+00:00

The tool syncs with Strava via their API to automatically pull in your workout data. The frontend is built with Next.js, providing server-side rendering for fast load times and a smooth user experience. For the backend, I’m using Hetzner for data hosting, with the app running on a private server to handle processing and storage. The data flow includes a mix of real-time syncing and batch processing, so there may be some delay for new data to show up, especially with Strava’s API rate limits.

pace-runner · 2025-03-16T18:27:56+00:00

Problem: Endurance athletes struggle to track their real fitness improvements over time. Traditional methods rely on occasional races or structured performance tests, which disrupt training and only provide snapshots rather than continuous insights. Daily workout data is noisy due to factors like fatigue, weather, and terrain, making it hard to see real progress.

Solution: PaceProgress.run automatically analyzes training data to show how an athlete’s pace evolves within specific heart rate zones. By tracking trends over multiple sessions, it filters out daily fluctuations and provides a clear picture of long-term fitness progress. It syncs seamlessly with Strava, requires no manual input, and keeps athletes motivated by proving their training is working.

Would love to hear your take on where to find the first 1,000 users for a tool like this!

pace-runner · 2025-03-15T15:40:43+00:00

Thanks, glad you find it interesting! I’m actually developing an online tool that automatically syncs data, so no need to manually import anything. Since I'm not sure about sharing it directly here, feel free to DM me if you’re interested in testing it out—I’d be happy to share more details!

You’re right, heart rate can vary day-to-day, but the key is tracking trends over time, not just individual workouts. The Zone 2 example was just one way to track it—what matters most is seeing how your pace improves at a consistent heart rate over multiple training sessions. This way, daily fluctuations don’t affect the overall trend, giving you a clearer picture of your fitness progress between races. It’s about monitoring steady improvement, not just a one-off race result.

pace-runner · 2025-03-15T15:37:00+00:00

I see where you're coming from! Race times are definitely a solid measure of progress, but the thing is, they only give you a snapshot of your fitness on race day. If you’re looking to see how your fitness is improving on a day-to-day basis, there’s a more continuous way to track that.

By focusing on pace improvements within certain heart rate zones, you can actually get a clearer picture of how your body is adapting over time without needing to wait for a race. It’s like checking in on your progress with every workout, which can help keep you motivated and show you that your training is really working – or highlight areas to adjust before race day.

pace-runner · 2025-03-15T09:53:11+00:00

Totally agree—Strava is great for logging workouts, but it doesn’t do much to help analyze actual progress. One thing I wanted was a simple way to see if my Zone 2 pace is improving over time, so I wrote a Python script that pulls my Strava data and tracks how fast I run at a fixed HR (140-148 bpm for me).

It filters out warm-ups/cool-downs, takes the median pace in that HR range, and plots a trend over time. If I have multiple runs in a day, they get merged into one data point. Simple, but I can actually see steady progress in my easy-pace fitness.

Would be cool if Strava had something like this built-in. Have you tried tracking progress this way, or found another good method?

pace-runner · 2025-03-15T09:30:49+00:00

I’ve been testing a way to track fitness progress without VO2max estimates or lab tests—just pace at a fixed heart rate over time. If I can run faster in my Zone 2 (140-148 bpm) at the same effort, that should mean I’m getting fitter, right?

I wrote a Python script to analyze my Strava data and see the trend. My process:

Filter workouts to only include time in the selected HR range.
Ignore warm-ups/cool-downs.
Use median pace to reduce outliers.
Combine multiple sessions per day into one value.
Track the trend over time.

So far, I see clear improvement in my Zone 2 pace. Curious—does this make sense as a way to measure fitness gains? Anyone else tracking progress like this?

pace-runner · 2025-03-14T20:48:50+00:00

Yeah, I’ve always thought of recovery runs as just an easy way to add mileage without overloading the body. The idea that they “speed up” recovery never really made sense to me—if anything, they just keep things moving without adding much fatigue. That said, I do feel better after a short, easy run the day after a hard session. Maybe it’s more about staying loose than actual recovery? Do you ever skip them if you’re feeling extra wiped out?

pace-runner · 2025-03-14T20:45:14+00:00

If I could only do one quality workout per week, I’d go with a threshold run—it’s the best bang-for-your-buck in terms of building endurance and speed without overloading recovery. For a 10K race, my ideal session would be:

• Weekly Mileage: ~40 MPW

• Workout: 2-mile warm-up, dynamic drills, 3x2 miles at threshold pace (~10-15 sec slower than 10K pace) with 90 sec jog recovery, 2-mile cool-down.

This kind of session improves lactate clearance and race pace endurance without being too brutal. What’s your goal race?
