It was an eventful night for Gime Toure, who both scored and was sent off, but the group game points went to the Cod Army thanks to goals from Callum Camps and Harvey Saunders (2). He was at Brunton Park for our 3-1 Football League Trophy defeat to Fleetwood at the beginning of September 2020. Obviously there were no goals, and there were also no names taken. We saw him here in Carlisle in October 2021 for what was a slog of a 0-0 draw. Fin Back and Jordan Gibson were booked that day. He had the whistle for our 2-0 away defeat at Stockport in October 2022. Kris Dennis scored a late consolation for the Blues, and Jayden Harris had his name taken. We saw him at Doncaster on New Year's Day in 2023 when the hime side took the lead through James Maxwell and Kyle Hurst. He has taken charge of 29 games so far this season showing 115 yellow cards and four reds. Our referee for this fixture is Mr Ben Speedie. Watch the highlights from that game here: Aaron Drinan extended the visiting lead to two goals after half time, and a strike on the hour from Jordan Gibson wasn't quite enough to open the door to a levelling of the scores. Archibald scored again moments later, and Edmondson was sent off to make the task ahead even tougher. Theo Archibald gave the visitors the lead, but Ryan Edmondson pounced to level things up. There was plenty to talk about after the O's took a 3-2 win from their trip to Brunton Park in October 2022.

Midfielder Paul Smyth has energy and a willingness to get forward, as shown by his goal return of 10 from 33 appearances. Seeing how Brentford have grown and how they've run it has become a blueprint." It's great to see what's happening there. "Brentford have got a fantastic ownership model, they have stayed true to their values. If we were to get promoted then talk of a new stadium is all about planning for the future, which is part of my responsibility - to keep one eye on what could happen going forward as well as keeping an eye on the day-to-day. When looking to address the isssues, chief executive Mark Devlin said recently: "I joined Orient just over a year ago and the club is at the same level Brentford were when I joined them in 2011. Promotion is by no means guaranteed, but as each game ticks by it looks ever more likely, and the club is already looking to the future as they prepare themselves to confirm a £1.5m loss. Their last defeat came in what was a mini-wobble at the end of January, when they lost back-to-back away games against Stevenage and Tranmere, but since then they've won four and drawn five in a nine-game unbeaten run. With just five defeats in the league all season it's little surprise that the O's sit at the top of the pile with automatic promotion well within their grasp.

I did the same with my other S2, just printed some custom Z Bronica logo. I found this an easy solution, and easy to remove in case I have to screw again. The laminating plastic well glued is required to avoid humidity sneaking its way into the cardboard. STEP 2: Remove virus from Internet Explorer, Firefox and Chrome. Glue and plastic don't like extreme temperatures so we'll see how it goes in winter by -30 or some +40 sommer place. STEP 1: Uninstall malicious programs from your computer. Take extra care insuring it does stick well. Glue some decorative circle over, in this case I used red duct tape and finish with a piece of self-laminating clear sheet sticking on the external steel edge of the bayonet. So I I just cut some piece of thick cardboard that I insert there. The bayonet is for the sport finder, which it don't plan to use: I don't like the bayonet on the speed dial, because it can get dirt inside, can hook something else accidentally like in the bag, and fingertips get into it. Clean then screw the bayonet back:Ĭut a piece of light cardbord to cover the inside of the lock before applying glue, to avoid getting it all over the screws under, then glue back the leatherette. Meanwhile I had the bayonet and cover dipped into ethanol in order to remove the dried glue residues. That did it, the dial is smooth as butter but clicks well into speed marks. Dried lubricant? But why would the spring pressure more than needed? No idea, whatever, I just stick a screwdriver and press a bit on the copper spring with the idea to lessen a bit the tension, and I apply a bit of light white grease:Īnd exercise the dial many many times back and forth. By the musty odour similar the one of clothes stored long time in an attic, when I received it, this camera hadn't been used in a while. There's no grease residue there, it's clean. Next step for delving into mechanism is obviously to peel some leatherette for underlying screws and remove the side panel.īUT, before going further I decided to check how it is with the brass ring with notches and the inner steel oneĪ piece of bent copper works as passive spring against the notches. Removed, we see the small deformation, but since it's so soft, easy to correct with some spanner for instance:ģ screws hold the black ring with painted shutter times. In fact it did stick strongly and I had to force, the hole was getting wider and it was bending like it's a piece of tin. I inserted the tip of a spanner in the hole and played with it. One hole means it's not screwed, otherwise there would be typically 3 screws, so it's clicked inside somehow or glued. So, remove the leatherette main circle and the narrower one, the metallic lock has one hole on the rim. But then I guess some other cases will require to get deeper into the beast. I was bracing myself for some sleepless night into complex watch-like mechanics, but I didn't need at all, it was so damn simple. It was hard to turn, so I had to have a look. This time it's about the shutter speed dial, the one on the left side. I had one back with light leaks, and posted about how I fixed it here in another thread. There's little DIY doc online for these cameras. It came with two backs, and I just check everything is ok. To fix the tooltips, wait till you can reach into the shroud again, then let a month tick by.So, another post about a bit of tinkering with the S2.Ĭontext is that I recently bought from Japan a S2, late model ie.

When analyzing a packet, you can add filters to catch and collapse fields you don’t care for. The filter syntax may be intimidating at first, but it’s extremely effective once the user the hold of it, whereas Wireshark is a graphical user interface tool that helps you to catch (or view captured captures) packets going in and out of an interface, similar to tcpdump. It accepts many filters and allows you to view data about packets entering and going out of an interface remotely via an SSH session. Tcpdump is a CLI-based packet capturing tool. Here are the following key differences mention below Key Differences between Tcpdump vs Wireshark Head to Head Comparison Between Tcpdump vs Wireshark (Infographics)īelow are the top differences between Tcpdump vs Wireshark We are going to see the difference between them. Wireshark & tcpdump are used for this analysis. Now, being able to intercept and inspect those packets is critical in order to determine which types of traffic in our network should be protected. A network’s traffic is essentially a flow of packets. Packet captures, and packet processing is used to analyze traffic. Log analysis, traffic analysis, and packet capture analysis are most important for network security. Tcpdump uses a command-line interface to provide packet content definitions in a variety of formats based on the command used. Tcpdump is a free, open-source network utility licensed under the BSD license. It is a packet analyzer that tracks and records TCP/IP traffic between a network and the machine on which it is run. Tcpdump is also one of the most used network analysis tools as it provides simplicity and efficiency in one interface. Device operators, network engineers, network security experts, as well as black hat hackers use Wireshark. It is now the most commonly used network management application. Wireshark is a network traffic monitoring tool that runs on a network interface. Wireshark is a popular network sniffing tool that provides GUI to decode many protocols and filters. This converted file can be opened in Wireshark.Web development, programming languages, Software testing & others Specify the input etl file and output pcapng file. Pktmon pcapng e:\capture.etl -o e:\capture.pcapng By which converted file can be open in Wireshark or open online in Packet Total type utilities for further analysis. But it provides a mechanism to covert ETL format into PCAPNG format. Pktmon create files in ETL format, a windows propitiatory format. This will stop the capture and file is generated.

Found in the higher mountain slopes and occasionally in riverbeds. It can grow up to several metres high and blooms with bright yellow flowers, usually in May. It has many branches that spread out from low down on the central structure. ramosissima): Less common than the other kokerbooms, this aloe resembles a shrub rather than a tree. The Maiden’s Quiver Tree, or Nooienskokerboom (A. Some of the largest species can grow up to 20 m tall. Most have a tall trunk and rounded crown. (15 cm) Sun exposure : Full Sun Madagascan Palm Family : Arecaceae Height : 6-8 ft. In the Richtersveld National Park, they can be seen in Helskloof and on Cornell’s Kop. Description Tree aloes form large trees and shrubs, with forked (dichotomous) branches. (4.7-6 m) Sun exposure : Sun to Partial Shade Eriosyce Species, Quisquito De Taltal, Taltal Quisquito Family : Cactaceae Height : under 6 in. They grow on mountain slopes close to the Orange River, from Baken to the Tatasberg, with a southern extension on the Dragon’s Back mountain near Eksteenfontein. Aloidendron dichotomum, formerly Aloe dichotoma, the quiver tree or kokerboom, is a tall, branching species of succulent plant, indigenous to Southern Africa, specifically in the Northern Cape province of South Africa, and parts of Southern Namibia. It has fewer, thicker branches and larger leaves than its cousin, A. It grows up to 10m tall with a thick stem. Pillan’s Quiver Tree, also called the Bastard Quiver Tree or Basterkokerboom (A. The kokerboom forest (more correctly called a colony) in the Richtersveld National Park is the best place to check out these ancient aloes. It’s found east of the Stinkfontein mountains and in the arid northern Richtersveld, where it tends to grow taller with simpler branch structures. It grows up to 9m high and is characterised by a large central stem with a broad spray of branches and leaves growing out of the upper reaches. These are: The plain old Quiver Tree/Kokerboom (Aloe dichotoma). In the Richtersveld, 3 of the 5 species of kokerboom can be found. This is quite a difficult alternative and success is not always guaranteed.The name ‘quiver tree’ refers to the Bushman and Khoikhoi hunters, who used to carry their arrows in hollowed-out kokerboom branches. Truncheons must be dried out for at least 3 weeks before planting in river sand. Truncheons can also be used for propagation. Plants can be grown from seeds planted in autumn, (March, April) in trays of coarse river sand. Bone meal is mixed into the soil to help feed the fleshy roots of plants. Always use a good quality, loamy sandy soil with plenty of drainage chips at the bottom of containers. Like all succulents it has developed in a specialised way to adapt to erratic and little rainfall. Inflorescence of a Quiver tree (photo D.P. Because the quiver tree is an aloe, it has fibrous wood. This is very rewarding as beautiful specimens can be positioned to enhance certain areas. In South Africa there are three quiver tree species: the well-known quiver tree (Aloidendrondichotomum), the shrub-like maiden’s quiver tree (Aloidendron ramosissimum) and the critically endangered giant quiver tree (Aloidendron pillansii). Alternatively, quiver trees can be grown in large containers. Plants such as Cotyledon orbiculata, Crassula rupestris, Cyphostemma juttae, and Tylecodon paniculata are special companion plants to quiver trees and will completely transform any garden. A position in a hot and dry rock garden is best if one wants to grow this aloe in open ground. Browse pictures and read growth / cultivation information about Aloidendron Species, Maidens Quiver Tree (Aloidendron ramosissimum) supplied by member gardeners in the PlantFiles database at Dave. Richtersveld, Northern Cape, South Africa. In wetter parts of South Africa such as the Western Cape, these plants are able to cope provided that the drainage is good enough to prevent rotting in the wet winters. The Maidens Quiver Tree makes multiple branches from ground level, and is lower-growing than Aloe dichotoma. Aloidendron dichotomum features quite prominently in gardens all over South Africa and other countries with a similar climate. It looks like the People of Faith, and Zoey’s horrid step-father in particular, are tired of living side-by-side with vampyres.

Even people who are not Christians or religious at all know the tune and the text to ‘Amazing Grace.’ “It spans the ages and it had spoken to generations and people from all different walks of life. “‘Amazing Grace’ is a timeless hymn,” noted Matt Swain, assistant dean of worship ministries at Midwestern Baptist Theological Seminary (MBTS). This year marks the 250th anniversary of the hymn, synonymous with Christian victory in the face of dangers, toils and snares, as well as man’s overwhelming sin. The seeds for each verse are in 1 Chronicles 17 for those who read closely. “Amazing grace, how sweet the sound, that saved a wretch like me.” So David’s prayer in the hands of a slave trader-turned-pastor named John Newton became the lyrics to one of the most sung hymns - or songs of any sort - ever. King David and Pastor John both were overwhelmed by God’s grace. For the sake of your servant and according to your will, you have done this great thing and made known all these great promises.” What more can David say to you for honoring your servant? For you know your servant, Lord. You, Lord God, have looked on me as though I were the most exalted of men. “And as if this were not enough in your sight, my God, you have spoken about the future of the house of your servant. “Who am I, Lord God, and what is my family, that you have brought me this far?” David asks. On New Year’s 1773 he was preaching through 1 Chronicles 17, expositing God’s promise to King David. In his old age, it was suggested that Newton retire because of bad health and failing memory.Most preachers wouldn’t dare tackle writing a sermon and a hymn for their congregation, but that was par for the course for Pastor John Newton and his peers. The hymnal, which includes Newton's hymns "Glorious Things of Thee Are Spoken" and "How Sweet the Name of Jesus Sounds," was reprinted in England and America for the next century. He also befriended poet William Cowper, and they collaborated to produce Olney Hymns, which became the standard hymnal of evangelical Anglican churches. He began writing his own, many autobiographical in nature, including "Amazing Grace!" Newton felt dissatisfied with the hymns of the traditional psalter. He was ordained within the Anglican Church, and in 1764 he took a curacy in Olney. Known as the "old converted sea captain," he attracted large audiences. He married his long-time sweetheart and began studying for the ministry and preaching in whatever vacant building he could procure. Newton became greatly influenced by George Whitefield and the Wesleys. He gradually came to abhor slavery and later crusaded against it. Ironically, Newton then served as captain of a slave ship for six years. Newton had read The Imitation of Christ, and during the life-threatening voyage he became a Christian. The following year his ship was battered by a severe storm. Newton's life during that period bore the appearance of a modern Prodigal Son's: "a wretched looking man toiling in a plantation of lemon trees in the Island of Plaintains-clothes had become rags, no shelter and begging for unhealthy roots to allay his hunger." After more than a year of such treatment, he managed to escape from the island, in 1747. He then headed for regions where he could "sin freely," and ended up on the western coast of Africa, working for a slave trader who mistreated him. John didn't care for the discipline of the Royal Navy: he deserted ship, was flogged, and eventually was discharged. But she died when John was a child, and he followed his sea-captain father to a sailor's life. John Newton was nurtured by a devoted Christian mother who dreamed that her only son would become a preacher. Some of these dependencies link the external library statically, some dynamically, and one ( openssl-sys) gives you the choice □ Running cargo tree -target armv7-unknown-linux-gnueabihf -prefix none | grep - '-sys ' | sort shows the *-sys dependencies which we’re going to need to link: alsa-sys v0.1.2 Throughout this article, we’re going to be working with spotifyd, an open-source background service that streams from Spotify.

Then, wrap the functionality from foo-sys in Rust-ier code, i.e.This is the ‘minimum viable’ binding to the library from Rust - it should basically attempt to map C functions directly to Rust and not translate anything to Rust types or paradigms. Make a crate named foo-sys, which defines the FFI for the foo (non-Rust) system library.The Rust ecosystem has a really nice convention for crates that do this: If we want to use them from our Rust code, we need to interoperate over a Foreign Function Interface – often referred to as FFI Interop 3. There are lots of great libraries that have been written in languages which aren’t Rust. Let’s talk about external libraries in Rust In the end, I provisioned an 8 CPU / 16 GB RAM / $0.238 per hour Droplet on Digital Ocean, which brought the clean build time down to 90 seconds – just remember to switch it off when you’re done! If you do decide to build on Mac, don’t forget to give your Docker VM a lot more resources than the meagre defaults, but honestly, you may as well just compile on the Raspberry Pi. I expected this to be the cause of a little bit of slowness, but clean builds on OSX took as long as on the much-lower power Raspberry Pi 2. On OSX, those technologies aren’t available, so Docker Desktop runs a Linux VM. Let’s get started! ⚠️ Warning: this is all terribly slow on OSX and probably Windows, use Linux insteadĭocker uses a whole bunch of Linux native technologies to provide isolation for a minimal performance cost. In this post, we’re going to make it work for a pretty simple project. Just because it’s fiddly, though, doesn’t mean it’s not tractable. This is a huge improvement on the former state of the art – just install two programs, and run the build command! But the simplicity starts to fall apart once you need to link external libraries – those that weren’t written in Rust and are (usually) distributed using a mechanism other than Rust’s cargo package manager. # Just replace the word 'cargo' with the word 'cross' in your # build command cross build -target =armv7-unknown-linux-gnueabihf Modern Rust makes it mostly not horrendous you can cross-compile a hello-world program in ~5 shell commands: With that out of the way… Cross-compiling pure Rust is really easyĬompiling code from one computer for another computer is called cross-compiling, and it’s historically been horrendous. If you’re thinking about setting up cross-compilation for your project, please carefully evaluate whether it’s really going to save you and your team time in the long run, and make sure you consider that an incremental build is probably much, much quicker than your initial build. It’s taken four days of intense trialling and erroring and footguns and now I’m writing about it to hopefully save you, Dear Reader, from trialling and erroring and footguns in the future. I decided to try and build the code on a much faster computer instead, and then copy the produced binary onto the Raspberry Pi.
