 Supervisor: Professor Mete Atatüre<br>
 <br>
 The project centered around the use of a Nitrogen-Vancancy defect in a nanoscale diamond to detect magnetic fields with ultra high resolution. We experimented with mounting such a nano-diamond to the tip of an atomic force microscope in order to produce field images. I built a 3d vector magnetometer in order to determine the axis of a defect in a nano-diamond.

-Check out a little interactive model of the magnetometer below.
+Check out a little interactive model of the magnetometer below. The device has three pairs of copper Helmholtz coils that generate controlled, linear, magnetic fields in all three directions.

+**AFM Tip**: The atomic force microscope tip in blue with a nano-diamond attached to the very tip. We want to figure out which was the axis the NV defect in this nano-diamond is pointing. To do that we need to expose it to different directions of magnetic field while also blasting it with light and radio waves.
+
+**PCB coil** For the radio wave blasting we have a single turn coil made on a PCB. I haven't cut the coil away so that you can see it's whole shape. We'll pump RF power into this tuned to the electronic transitions in the NV defect that we want to probe.
+
+**Microscope Objective** The microscope objective allows us to optically pump the transitions in the NV defect (much like a laser) in order to keep electrons in excited quantum states that they wouldn't normally sit in.
+
+By putting in varying currents through the three coils pairs we can create a very well controlled magnetic field in any direction and of varying strength. We can then run a sweep through all the possible field directions while blasting the NV center with light and RF in order to determine it axis with respect to the plastic housing of the tip. 
+
+This is how you would calibrate one of these magnetism sensing AFM tips after first sticking a diamond to the tip.
+
+Once we know the axis direction this AFM tip could then be transferred back to the AFM to measure magnetic fields at the nanoscale!
+
+TODO: Explain this in a bit more detail.

+title: "Selfhosting: Miniflux and RSSHub"
+layout: post
+excerpt: Some notes on selfhosting an RSS reader.
+---
+
+Like many nerdy, computery types, I like to subscribe to blogs and other content through RSS. RSS is crazy simple, you host a url on a website with a list of posts with titles/URLs/content encoded in XML (I know I know but it only have like 5 tags and is only nested one level deep.) An RSS reader just checks a big list of those URLs every now and then and presents you the latest thing to show up. 
+
+Incidentally this is also how podcasts work, at least for a while, Spotify is clearly trying to capture it.
+
+Anyway, I usually use [theoldreader](https://theoldreader.com/) to read RSS feeds but lately they've implemented a premium version that you have to pay $3 a month for if you have more than 100 feeds (I have 99...).
+
+Honestly, I use their service a lot so somehow $3 doesn't seem so bad, but it spurred me to look into selfhosting. 
+
+Selfhosting seems to be all the rage these days. Probably in response to feeling locked in to corporate mega structures, the aforementioned computery nerdy types have gone looking for ways to maintain their own anarchic web infrastructure. See i.e [the indieweb movement](https://indieweb.org/), [mastodon](https://joinmastodon.org/) etc etc etc
+
+So I want to try out some self hosting. Let's start with an RSS reader. [Miniflux](https://miniflux.app/) seems well regarded. So I popped over their, grabbed a `docker-compose.yml`, ran `docker compose up -d` and we seem to be off to the races.
+
+Ok, a nice thing about Miniflux when compared to theoldreader is the former seems to be better at telling you when there's something wrong with your feeds. It told me about a few blogs it couldn't reach, notably [Derek Lowe's excellent blog about chemical drug discovery](https://www.science.org/blogs/pipeline).
+
+That blog has an [rss feed](https://www.science.org/blogs/pipeline/feed), which loads perfectly find in my browser but doesn't seem to work when outside of that context, i.e in python:
+
+```python
+>>> import requests
+>>> requests.get("https://blogs.sciencemag.org/pipeline/feed")
+<Response [403]>
+```
+
+Playing around a bit more, adding in useragents, accepting cookies and following redirects, I eventually get back a page with a challenge that requires JS to run. This is the antithesis of how RSS should work!
+
+Ok so to fix this I came upon [RSSHub](https://docs.rsshub.app/en/) which is a kind of RSS proxy, it parses sites that don't have RSS feeds and generates them for you. I saw that this has pupeteer support so I'm hopping that I can use it to bypass the anti-crawler tactics science.org is using.
+
+Anyway, for how here is a docker-compose.yml for both miniflux and RSSHub. What took me a while to figure out is that docker containers live in their own special network. So to subscribe to a selfhosted RSSHub feed you need to put something like "http://rsshub:1200/" where rsshub is the key to the image in the yaml file below.
+
+EDIT: I got it to work using puppeteer! For now the code is in a [branch](https://github.com/TomHodson/RSSHub/tree/science_blogs) for which I'll do a proper PR soon.

+title: My First Half Marathon!
+layout: post

+social_image: /assets/blog/running/time_vs_distance.png
+alt: A scatter graph of run time vs run distance for all my runs on strava. It shows that I mainly run between 5 and 6 min per kilometer, regardless of distance 
+---
+
+I recently ran my first half marathon! I'm also signed up for a full marathon in October. 😬
+
+Anyway, to celebrate the occasion and because I have now have a reason to think about how fast I might run a particular distance. I had a look at my historical run data. There's a great website called [statshunter](https://www.statshunters.com/) that you can authorise to Strava and from which you can download a little csv of all your runs. The first logical thing I could think to do is to see how fast I tend to run different distances.
+
+<figure>
+<img src="/assets/blog/running/time_vs_distance_plus_hist.svg"/>
+<figcaption>
+So it's pretty much a straight line. This is telling me what I kinda already knew: I'm comfortable running between 5 and 7 mins/km and that's basically how fast I always run regardless of distance. 
+</figcaption>
+</figure>
+
+A friend lent me a huge running book which I'm going to dig through more but I suspect one of the conclusions will be a bit obvious: I could run those shorter distances a lot faster.
+
+That same friend also lent me a heart rate watch which I've been playing with. So the next thing I want to learn about is what type of heart rates you should target when you train for a particular event. 
+
+
+Code:
+
+```python
+from matplotlib import pyplot as plt
+import numpy as np
+from datetime import datetime
+import pandas as pd
+
+runs = pd.read_csv("runs.csv", parse_dates = ["Date"]) # Get this from statshunter.com
+
+f, (ax2, ax) = plt.subplots(nrows=2, figsize = (5,5), sharex = True,
+                           gridspec_kw = dict(height_ratios = (1,2)))
+
+ax.set(ylabel = "Moving Time (mins)", xlabel = "Distance (km)")
+
+x = runs["Distance (m)"].values/1e3
+y = runs["Moving time"].values/60
+
+dists = np.linspace(1, 25, 2)
+for i in [5,6,7]:
+    mins_per_km = i * dists
+    ax.plot(dists, mins_per_km, color = "black", linestyle = "dotted", label = f"{i} min/km")
+    ax.text(25.5, 25*i, f"{i} min/km", va = "center")
+
+ax.annotate("Half Marathon!", (x[0], y[0]-1), (20, 50), arrowprops = dict(arrowstyle = "->"))
+
+ax.scatter(x, y, s=20, alpha = 0.6*fade_out_by_date(runs["Date"]))
+for a in [ax, ax2]: a.spines[['right', 'top']].set_visible(False)
+
+ax2.hist(x, bins = 30, alpha = 0.5)
+ax2.set(yticks=[], ylabel = "Frequency Density")
