L'ancien modèle a les 3 attaches flottantes.

Sur le nouveau, les attaches sont liées pour éviter de les perdre (et suppression des porte gels).

Cela semble être une bonne idée.

Mais comme l'attache n'est pas plaquée, est ce que le dossard ne flotte pas un peu ?

Des avis ou des expériences ?

In Spain for the eclipse next month. Got a Nikon Z8 with:

• 180-600mm f/5.6-6.3
• 70-200mm II f/2.8
• 1.4x and 2.0x teleconverters

I’ve read that 2750mm fills the frame vertically. With my setup, I’m torn between 400mm (200x2) or 840mm (600x1.4). Both seem like a solid middle ground, and I can always crop later.

Thoughts? Anyone shot an eclipse with similar gear before?

I'd like to have in same time an AI HAT+ like this one (see picture) and have in same time an NVME disk.
I found a way for adding two NVME disks with one PCIe (https://shop.pimoroni.com/products/nvme-base-duo-for-raspberry-pi-5?variant=41434434895955) but I need one PCIe and one NVME connector.

There is only one PCIe connector. Any advice or solution ?

Comment fixer vous votre dossard lors des courses ?
- À l’ancienne avec des épingles
- Avec des aimants
- Avec des clips mâles / femelles
- Avec une ceinture qui à des fils élastiques à passer dans les trous
- Autres

Et à quel endroit pour avoir moins de gêne lors de la course ? 🤔

Quels sont vos retours d’expérience et pratiques ?

I’m having an issue with my Husqvarna LB 553S e lawn mower, and I’m hoping someone here can help. The problem is with the handlebar: no matter how tight I secure the handlebar grip (even if I overtighten it—see the photo with the twisted grip), the handlebar won’t stay in place. It keeps tilting to the left or right while I’m mowing, which makes it really frustrating to use.

Has anyone else experienced this? I’ve checked the bolts and clamps, but everything seems to be in place. Could it be a worn-out part, or is there a specific way to adjust or replace the handlebar mechanism?

Any suggestions or tips would be greatly appreciated!

I’ve been using Intervals.icu alongside my Garmin, and I’m a bit confused by the mismatch in heart rate zones. Garmin gives me 5 zones, while Intervals.icu uses 7. How do you guys handle this in your training?

My Garmin zones:

• Z1: 86–103 (Warm Up)
• Z2: 104–120 (Easy)
• Z3: 121–140 (Aerobic)
• Z4: 141–156 (Threshold)
• Z5: >157 (Maximum)

Intervals.icu zones for the same activitie:

• Z1: 0–129 (Recovery)
• Z2: 130–136 (Aerobic)
• Z3: 137–144 (Tempo)
• Z4: 145–152 (SubThreshold)
• Z5: 153–156 (SuperThreshold)
• Z6: 157–161 (Aerobic Capacity)
• Z7: >162 (Anaerobic)

I try to adjust Garmin vs Interval.icu (sorry my table is in french):

Do you just stick to one system for analysis, or do you adjust your Garmin zones to match? Any tips for making sense of the overlap (e.g., Garmin’s Z4 covers both SubThreshold and SuperThreshold in Intervals.icu)?

Would love to hear how others handle this!

Hi r/linuxadmin and r/sysadmin,

I’m setting up a backup solution for several Linux servers (on-premise, behind NAT - I can set up firewall rules) and I’m torn between two architectures for security and reliability:

Option 1: Backup Server Pulls Data

• The backup server (e.g., running Borg, Restic, or Bareos) initiates connections to each client, pulls the data, and stores it.
• Pros: Centralized control, easier to enforce policies, and clients don’t need outbound access (only inbound).
• Cons: Requires inbound ports open on clients (firewall rules, potential attack surface).

Option 2: Clients Push Data

• Each client runs a backup agent (e.g., restic, borg serve, or rclone) and pushes data to the backup server.
• Pros: Clients only need outbound access (easier with NAT/firewalls), no inbound ports open.
• Cons: Harder to enforce consistency, clients might fail silently, and credentials are distributed.

Tools I’m considering:

• Borg (+ Borgmatic) for deduplicated, encrypted backups.
• Restic for simplicity and encryption by default.
• Bacula/Bareos for enterprise-grade features.
• Rclone for cloud/remote storage sync.
• Proxmox Backup Server (if I virtualize).
• ReaR for bare-metal recovery.

Security Focus:

• Which model (pull vs. push) is actually more secure in a real-world scenario?
• How do you handle authentication (SSH keys, TLS, API tokens)?
• Any horror stories or lessons learned with either approach?

Bonus Questions:

• If using pull: How do you secure the backup server’s access to clients (e.g., SSH jump hosts, VPNs)?
• If using push: How do you ensure clients can’t overwrite each other’s backups or fill up storage?
• Are there tools that hybridize both models (e.g., backup server triggers clients to push)?

Context:

• Servers are on a private network (NAT’d), with a mix of physical and VMs.
• Backup server is dedicated (Linux, likely Debian/Ubuntu).
• Goal: Immutable, encrypted, versioned backups with minimal attack surface.

Actual solution : rsnapshot on hosts then some sync.

Thanks for your insights!
(And yes, I’ve read the docs—now I want your battle scars.)
