Bœuf Talk (sorry vegans): Fore Part Deux: Hind UK Edit: oops, not a TV show, don't feel like moving it. 😎

Tried 40s now trying 28s. These feel faster for sure but not sure how they'll do on shittier roads and more challenging decents. Thinking the sweet spot for me might be 32s.

I'm a 30/32 guy on the road. I think my Roubaix maxes out at 32 and that's what's on it now. I have a pair of 30s in reserve for when those wear out and won't sweat the difference.

wait, is that just your neighbors garden? ” they are just growing wild honey.”

Ooh, haven't made jambalaya in quite some time. Thanks for the reminder,. I guess I have a Costco visit in my near future for shrimp, sausage and peppers.

Jordan Jensen’s 2025 Netflix comedy special Take Me With You. Probably the best set I’ve seen in a while. [NSFW]

+1 for Unifi Cool RGB / Blinkenlights Power over ethernet (PoE) means you run single wire installs to both network and power your equipment. and daisy chain them to where you need them. Plenty of info / tutorials on YT. Your use case? Router (that supports PoE) where the internet comes comes into the property connected to a UPS, That enables the first building, Ethernet to the other two buildings then add switches and Wireless access points as required. simples.

In my opinion the current prices on ebay for a Keithley 2015thd are rather high. To note, the more modern version of my software only supports the National instruments gpib to usb adapter rather than the hp 82357b. This is because I could never get the 64bit drivers to work with the Chinese fake 82357b whereas the Chinese fake national instruments adapters work fine with 64bits (my 82357b also died and i replaced it with the ni and so could not test the hp anymore). If you don't want to get a gpib adapter, rs232 is also supported - its slower to transfer the data from the Keithley to the software (around 2 to 4 times slower but you only really notice this on long transfers such as full ffts or on automatically repeated measurements) once the transfer is complete the software performance is the same. the software has been written and tested under windows. theoretically it could run or be adapted to run on Linux or mac since it is written in java - but I have no interest in spending time on that. Some of the Keithley's more interesting features are only available via gpib/rs232 and the programming guide has multiple errors and omissions and does not in some cases give vital information which means figuring out simple things like how wide in Hz a FFT bin is, is a real pain in the **** - and the width varies with the fundamental frequency in non-linear way. Keithley provide no software or programming libraries and so you are left on your own. You can't even get the frequency of a bin or ask for the bin at a certain frequency on the 2025/6thd (you can on the (2015/6P) which seems crazy. The user interface on the keithley is not that intuitive. Due to some (I assume) design/cost limitations it only has as a maximum of 1023 fft bins which limits its resolution and for fundamental frequencies less than 60hz it can't differentiate noise from distortion since the bin width is the exactly the same as the fundamental, i.e. EVERY bin contains distortion and there are no noise bins. Despite this it will give you a thd+n result for a fundamental of 50hz with no warning that its actually a thd without n calculation! If you set the keithley up with filters or limit the number of harmonics the keithley can not provide unfiltered results. i.e. it only shows on screen and passes to a program the filtered results. There is no way to get at the raw readings. So from a programming point of view its often better to do a full fft and the calculate the thd, thd+n, sinad, noise and apply filters in software than rely on the keithley to do it. On the thd version the fft automatically locks onto the highest bin as the fundamental and if there are two highest bins this causes issues. The fft on the thd has no reliable way for you to manually specify the fundamental frequency, there is a hack but you can only specify a sub multiple of the fundamental frequency in the range 20-68hz and even then the fft is not as clean as automatically locking. The harmonic calculation is limited to a maximum of 64 harmonics regardless of how many harmonics are present in the fft. there are also some firmware bugs (at least in the firmware I have) and there seems to be no reasonable way to get new firmware. The built in signal generator only goes from 10hz to 20K and has a surprising amount of jitter and at 20 hz it can output 19.Xhz which causes issues. The thd/thd+n and sinad only accept fundamentals from 20hz to 20K and at 20Khz there is only the fundamental and 1 harmonic since the fft is hard bandwidth limited to 50khz. Noise calculations are limited to fundamentals in the 60hz-20K range. In short the Keithley shows its age and requires a lot of programming and reverse engineering to understand what's actually going on under the hood. The 2015P and 2016P remove many of the programming limitations of the 2015/6thd and it would be interesting to know if a thd could be upgraded to a P model - it might only be a firmware change since the thd programmatically seems to be a gimped P with certainly very useful programming features missing. Unfortunately the P models are double the price of the thd... Here are a couple of measurements of the Keithley's signal generator feed back directly into its inputs. At least on my unit, the generator has around 0.02% THD at 1V rms output (using single ended - not balanced). Using a good PC sound card instead the thd can be cut by around a factor of around 5-10. So the measurement of the keithley is more capable than the built in signal generator.. Signal generator harmonics at 20Hz (10 averages minimum and maximum values also shown) Signal generator noise and harmonics at 1Khz (10 averages) signal generator THD vs frequency of its output (averages of 10 measurements, minimum and maximum shown note log scale for x axis frequency) Notice how there is considerably more THD at 20hz... this is because when 20Hz is requested the output of the signal generator is actually 19.X and this causes issues with the fft lock on the Keithley. Noise of the keithley signal generator vs frequency of its output (10 averages min and max shown log scale for frequency) notice the rising noise as frequency increases but there is a huge noise spike at 9.95Khz and smaller spikes at 85hz, and 19.86Khz. I have not put any effort into determining if this is caused by the measurement side of the Keithley, external noise or the Keithley signal generator. THD+N of course shows the issues with 19.zHz locking and the noise spikes: here is a graph of just the second harmonic from the signal generator. again 10 averages min and max shows log scale for frequency. notice the large variations between minimum and maximum at low frequencies. These variations decrease with increasing 2 harmonic frequency. Third harmonic is cleaner but still shows the effects of the 19.9hz lock on issue and the trend for the variation between minimum and maximum measurements to decrease as the harmonic frequency increases. frequency response of the signal generator is reasonably flat at +0.0db to -0.024db at 420Hz.

You know, I normally hate harsh vocals. But every once in a while, it brings me joy. Like this. (And Nemophila.)

I don't use mesh but I will definitely also recommend Unifi. I have a Cloud Gateway, a U6 WAP and one of their switches. The whole system was a dream to setup and piecemeal upgrade-able should I need it. No required subscriptions or cloud BS either for the security-minded folks.

Look into unifi wifi https://ui.com/wifi It's meant for covering a large area with easy integration of multiple access points. You could put one access point in the main house and another in the loft over the garage and you should have excellent coverage everywhere. You would need to install the controller on your computer to set everything up, but once it's running you don't really need to do anything else. It would also give you the ability to easily monitor it all while you're away. You could continue to use the current router, or you could use a unifi router (I have an extra in a box that I never opened of you want it).

Dipping in to the structured workouts on Zwift. What a cool tool. I like how they have little drills built in like working on different cadences or emphasizing different parts of the pedal stroke. Erg mode is also nice to get a feel for what it feels like to hold steady power, something I'm not that good at yet. I'm glad I didn't start out with this and just rode the bike for months, but I can only see it benefitting my outdoor rides.
