Adaptive Load Balancing: This mode optimizes the network traffic received and sent by Synology NAS devices regardless of whether Link Aggregation is enabled or not. To avoid unexpected circumstances, do not enable Link Aggregation even though it is supported. IEEE 802.3ad Dynamic Link Aggregation: This mode optimizes network traffic received and sent by Synology NAS devices, which requires IEEE 802.3ad (Dynamic) Link Aggregation (LACP, 802.1AX) to be enabled on the Switch , and if multiple switches are used, they must be properly stacked and configured. Balance XOR: This mode will balance the network traffic received and sent by Synology NAS devices, this mode requires Static Link Aggregation to be enabled on the Switch. If multiple switches are used, they must be properly stacked and configured. If the switch does not support Link Aggregation, the traffic by the Synology NAS device is still balanced. With this mode. disconnection can be identified but not the cause (For example, when an Ethernet cable is not connected or the switch has a configuration error). Active / Standby: This mode will provide error correction, that is, when one network connection is disconnected or the connection is unstable, the other one will take charge as the main connection. You can choose this configuration whether or not the switch configuration supports IEEE 802.3ad Link Aggregation.

Link Aggregation (LACP) will allow you to increase the bandwidth TO and FROM your Synology NAS. In summary, this will allow more clients to send data to and from your NAS without decreased performance. To be clear, this will not double the network speed for a single client.

3d resources to 3d print these compliant mechanisms

Link to the original article

I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell: https://www.compliantmechanisms.byu.edu

At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.

What I learned about compliant mechanisms I summarize in the 8 P's of compliant mechanisms:

1. Part count (reduced by having flexible parts instead of springs, hinges)
2. Productions processes (many, new, different enabled by compliant designs)
3. Price (reduced by fewer parts and different production processes)
4. Precise Motion (no backlash, less wear, friction)
5. Performance (no outgassing, doesn't require lubricant)
6. Proportions (reduced through different production processes)
7. Portability (lightweight due to simpler, reduced part count designs)
8. Predictability (devices are reliable over a long period of time)

The Raspberry Pi is not limited to Raspberry Pi OS. It’s the official distribution, but is far from being the only one. Depending on the model you use, your goals, and your personal preferences, it might be a good idea to examine other options. I tested all of the other options and share my favorites in this post, which should be a great starting point for you.

Apple used the Razer Blade 15 Advanced as a point of comparison for the performance of the M1 Max chip. Here's how the rest of the notebook compares against the 16-inch MacBook Pro.

As part of Apple's promotion of its new M1-series MacBook Pro system-on-chip options, it made claims comparing the performance of the SoCs against existing on-the-market notebooks.

One comparison of the M1 Max with the 32-core GPU option claimed it offered "graphics performance comparable to that in a high-end compact PC pro laptop using up to 40% less power." A closer inspection of the press release has Apple saying that compact notebook was the Razer Blade 15 Advanced, complete with the model number, RZ09-0409CE53-R3U1.

The Razer Blade 14 has been updated for 2022 to make it more powerful, but it has to fight with the 14-inch MacBook Pro as a creator's choice notebook. Here's how the two laptops compare.

Of all of the gaming brands on the market, it's arguable that Razer is the most Apple-like. It has cultivated a cool brand, a distinctive style, and impressive hardware to match.

Out of the entire collection of products, the Blade notebook range is probably the closest to an Apple-style product. They are gaming notebooks that attempt to provide considerable performance to users, while offering a MacBook Pro-style thin design and portability instead of a hefty notebook that swamps a desk.

Mechanical Watch In the world of modern portable devices, it may be hard to believe that merely a few decades ago the most convenient way to keep track of time was a mechanical watch. Unlike their quartz and smart siblings, mechanical watches can run without using any batteries or other electronic components. Over the course of this article I’ll explain the workings of the mechanism seen in the demonstration below. You can drag the device around to change your viewing angle, and you can use the slider to peek at what’s going on inside:

The process of building a website has two parts: you provide the content, and then your CMS — WordPress, or whatever you choose to use — takes that content, combines it with your chosen theme and your chosen templates, and makes a website from it for your customers or your readers to read.

But those two parts don’t have to be done together: they can be separated from one another, and that’s what a static site generator (SSG) does.

Autofocus Variations Can Ruin Your Focus Accuracy Whilst the autofocus has been improved with successive generations of the camera is still relies upon contrast detection to set the focus point. So the camera moves the lens to the point of maximum contrast and then steps forwards and backwards to get the precise point. Because of mechanical tolerances in the focus mechanism sometimes the repeatability of the focus point is questionable. I noticed some of my shots were not exactly sharp at the pinpoint area that I knew I had set the camera to when I took the shot. So I set up my DSLR focus chart used to correct the optical viewfinder to sensor calibration and shot a series of 10 images in AF single area and smallest target size. There was a noticeable shift in a lot of the images as you can see from the resulting images. Compare that to the same target where I manually set the focus point.

The Raspberry Pi Imager is a great piece of software for preparing your SD cards for use with Raspberry Pis. However, if you’re setting up a number of Raspberry Pis you will find that you still need to connect a monitor, keyboard and mouse to them to complete the setup, to:

• update the wifi ssid and password
• change the hostname and default password
• change localization settings

There is another, better alternative to doing those 3 steps - use the Raspberry Pi Imager secret menu.
