![]() ![]() A person is better able to control and coordinate their activities, suggesting higher executive functioning. Synchronization theory of flow: In this theory, regions of the brain communicate better during flow.Functional MRI (fMRI) studies suggest that there is lower activity in the prefrontal cortex, an area involved in executive functioning, during flow. This decline prevents a person from actively thinking about themselves, enabling them to immerse themselves fully in the task. Transient hypofrontality hypothesis: In this theory, executive function temporarily declines.Researchers have proposed two main theories for how flow affects the brain: Flow might then further stimulate dopamine, creating a cycle. It is possible that both are true.įor example, activating the dopamine system might enable flow. It is unclear whether entering a state of flow causes these changes or whether these brain changes cause or enable flow. During flow, a person must have high levels of engagement with a challenging task that matches their skill level for this system to regulate task engagement properly. This brain system helps regulate decision making and engagement with tasks. People in a state of flow have higher levels of dopamine, which could explain why they might not notice that they are hungry or tired.Ī 2021 mini-review argues that the brain’s locus coeruleus-norepinephrine (LC-NE) system is also involved in flow. It can also help suppress bodily sensations, such as hunger. Studies have shown that the dopamine reward system plays an important role.ĭopamine is a neurotransmitter that supports feelings of motivation, pleasure, and reward. Persistence: Some evidence suggests that being in flow can offset the frustration of a difficult task, allowing people to keep going.ĭuring a state of flow, several changes take place in the brain.Enjoyment: People may enjoy the task, encouraging them to immerse themselves in it.Lack of self-consciousness: Flow is associated with a decrease in “self-referential thinking,” which means that a person in this state is unlikely to be thinking about themselves, their performance, or how others might see them.If a person or event interrupts someone in flow, they may feel annoyed. ![]() They may not be thinking about anything else. Focus: It is not easy to distract people in flow from their task.Some signs that a person is in a state of flow include: in-depth, involving an investment of some time or energy to make progress.rewarding, meaning that a person gets a sense of pleasure or purpose from doing it.challenging, but not so much that they are impossible.Tasks that tend to encourage a state of flow often share similar characteristics.

![]() On that note, my USB3 is still not perfect. This worked however USB3 port detection was broken, and caused USB3 devices plugged into the USB3 port to only run at USB2 speeds. I had previously done the “splice” by using two adapters - internal USB3 header -> USB, plugged Bluetooth into one port, then the remaining port back into another USB -> internal USB3 header -> front panel connector. No bios setting seems to help (Tried all sorts including X/EHCI handoff, XHCI mode, etc).Ī fun artefact of this has meant that I could not connect my Bluetooth controller USB connection into an internal USB2 header and instead have had to splice my front panel USB connector in order to get it connected to the XHC bus where I can set the port to internal to avoid random wake when going to sleep ( source) The lower rear 4 USB3 ports on my board are completely unusable as they are routed via a JMicron controller.įor the life of me I have not been able to figure out how to get the rear USB3 ports be routed via the XHC controller instead of the EHC controller with internal hub. This routing is clearly apparent when viewing the USB info in System Information USB2: HP23 (via EH02 -> PR21 internal hub) ![]() USB2: HP24 (via EH02 -> PR21 internal hub) USB2: HP25 (via EH02 -> PR21 internal hub) USB2: HP26 (via EH02 -> PR21 internal hub) I continued to use my custom SSDT for USBInjectall for now. Unfortunately my rather old chipset has some weird internal hub configuration, which meant I could not figure out how to inject internal hub ports. I previously had performed USB mapping/injection with USBInjectAll, however I recently found that USBInjectAll can be avoided entirely with the use of an injector kext (i.e. The only difficult part of my upgrade was debugging some USB3 issues and getting sleep to work again. I am now already looking forward to even minor OS patch updates which I had previously deferred time and time again when using Clover in case of the event that it borked my setup and I had to roll back. I was now running Catalina without any pain. I gave this a go, and to my surprise, all went very smoothly. I now came to realise I could probably attempt an in-place upgrade by running the “Install Mac OS Catalina” directly within my running system rather than booting from a USB and doing a fresh install. I removed all traces of Clover and installed OpenCore to my SSD’s EFI. After a few tweaks I was booting successfully. I followed the OpenCore desktop guide to setup my install USB for Catalina as configuring OpenCore itself.Īfter doing so, I thought I’d just give booting my Mojave system directly with the new OpenCore bootloader on the USB to rule out any Catalina specific issues. I tested that I could boot directly from this. Additionally, I installed Clover on the drive and copied my working EFI configuration. I first cloned of my current Mojave setup to an external USB3 SSD, so I could safely roll back if it all came crashing down. USB3 partially working - front USB ports randomly disconnect drives □♀️ Everything else seems fine (Yes, my system is quite dated, so probably going to be looking into an upgrade next year, however it still runs great! I am a software engineer so most of my time on my machine is spent writing code and it does a great job at this.) Jmicron Controller (lower 4 ports on rear), Unsupported It was a surprisingly smooth process, not going to lie! As an added bonus I transitioned from Clover to OpenCore. Spent the Easter long weekend upgrading from Mojave to Catalina. Rotate (i* 10 ) drawpath (path.It's not the connection im my case it retrieves the values (IĬan see them on a list and they look fine), it's when you try toĬonnect it to the "make point" that the "null" error appears. #_ctx.fill(path.fill) #_ctx.stroke(path.stroke) #_ctx.strokewidth(path.strokewidth) # Use copies of the paths that adhere to the transformations.įinally, remember that when you want to supply one path multiple times to drawpath(), each with its own translation and rotation, you need to feed copies of the path to drawpath: path = svg. translate ( (-x-w )*origin, (-y-h )*origin ) for path in paths: scale ( scale ) (x, y ), (w, h ) = bounds (paths ) "" " Draws a group of paths that rotate and scale from the given origin.

By default origin is (0.5, 0.5) which means the center of the group. The second command, drawpaths(), draws all of the paths rotating and scaling from the given origin. The first command, bounds(), calculates the position and total size of a list of paths. ![]() Below are two commands to help you along. All of these paths may make up a single drawing and you may encounter difficulties when rotating and scaling the drawing a whole. When you import an SVG file a list of paths is returned. Stroke ( 1, 0.5 ) strokewidth ( random ( 0.5 ) ) if prev != None: Prev = None autoclosepath ( False ) nofill ( ) for pt in path. You can see it in use in the Superfolia project in the gallery. The bottom paths are darker to create a sense of depth.īelow is some example code used to alter the path. After some fumbling with paths and a nice gradient background, here is a hairy version of our flower. ![]() Since all of the imported artwork are standard NodeBox paths, I can also manipulate them with path mathematics, transform them like the LetterKnitter. We only fill paths that are closed, in shades of the same color: In the following example we override the colors in the original document. parse (data ) for path in paths:įill ( random ( ), 0, 0 ) drawpath (path ) Those that have a fill color will retain their original fill. Read the tutorial on paths to see what you can do with the points of a path.įor example, here's one of Ludivine Lechat's Illustrator drawings. These can be used to copy color information from the original vector drawing. path.strokewidth: the stroke width of the path in the SVG file.path.stroke: the stroke color of the path in the SVG file.path.fill: the fill color of the path in the SVG file.path.closed: is set to True when the path is closed.When set to True, the SVG source is analyzed only once and the parsed paths stored in memory so they load faster.Įach returned path in the list has the following properties: The command has an optional cached parameter. The parse() command reads SVG source and returns a list of paths that are drawable with drawpath(). Importing SVG files parse ( str, cached= False ) The regular SVG format saves all swatches and patterns, which is useless outside of Illustrator. ![]()
