Jurgen Klopp has surprising Rhian Brewster transfer U-Turn – Report
by Jordan ChamberlainJurgen Klopp will now allow Rhian Brewster to leave the club on loan in January, says an ‘exclusive’ report by Football Insider, who claim to have received information from a Liverpool source.
Liverpool refused to grant the 19-year-old a summer exit with the player himself stating the manager told him in no uncertain terms he’d be staying for the campaign…
“Yeah, I spoke to him at the beginning of the season and he just said ‘no’. He doesn’t want me to go on loan, he wants me to stay,” Brewster told FourFourTwo, cited in the Star, at the end of September.
“So that’s fair enough and it’s good to hear.”
But the young striker has only featured in the EFL Cup so far, playing 90 minutes against MK Dons and Arsenal and failing to score or assist in the process.
He’ll be in the side that faces Aston Villa in the quarters, but the fact he has yet to be given a single minute in the Premier League or Champions League is strange considering the hype about his role this term before it began.
The reality though is that Liverpool are top of the table and eight points clear and will win our Champions League group with an Anfield victory over Napoli midweek.
With the current seniors performing so well, Klopp clearly doesn’t feel it’s time to blood young talent and has rightly prioritised winning over everything.
Brewster though needs minutes – and a January loan – perhaps to a good Championship side and not a struggling Premier League one – might be the most sensible bet.

SwiftCairo
A Swift wrapper around cairo-1.x that is largely auto-generated from gobject-introspection. For up to date (auto-generated) reference documentation, see https://rhx.github.io/SwiftCairo/
Prerequisites
Swift
To build, you need at least Swift 4.2 (Swift 5.x should work fine), download from https://swift.org/download/ – if you are using macOS, make sure you have the command line tools installed as well). Test that your compiler works using swift --version
, which should give you something like
$ swift --version
Apple Swift version 5.2 (swiftlang-1<IP_ADDRESS> clang-1<IP_ADDRESS>)
Target: x86_64-apple-darwin19.4.0
on macOS, or on Linux you should get something like:
$ swift --version
Swift version 5.2 (swift-5.2-RELEASE)
Target: x86_64-unknown-linux-gnu
GLib 2.46 and Cairo 1.14.10 or higher
These Swift wrappers have been tested with glib-2.46, 2.48, 2.52, 2.56, 2.58, 2.60, 2.62, and 2.64. They should work with higher versions, but YMMV. Also make sure you have gobject-introspection
and its .gir
files installed.
Linux
Ubuntu
On Ubuntu 16.04 and 18.04, you can use the gtk that comes with the distribution. Just install with the apt
package manager:
sudo apt update
sudo apt install libcairo2-dev libcairo-gobject2 gobject-introspection libgirepository1.0-dev libxml2-dev
If you prefer a newer version of gtk, you can also install it from the GNOME 3 Staging PPA (see https://launchpad.net/~gnome3-team/+archive/ubuntu/gnome3-staging), but be aware that this can be a bit dangerous (as this removes packages that can be vital, particularly if you use a GNOME-based desktop), so only do this if you know what you are doing:
sudo add-apt-repository ppa:gnome3-team/gnome3-staging
sudo apt update
sudo apt dist-upgrade
sudo apt install libcairo2-dev libcairo-gobject2 gobject-introspection libgirepository1.0-dev libxml2-dev
Fedora
On Fedora 29, you can use the gtk that comes with the distribution. Just install with the dnf
package manager:
sudo dnf install cairo-devel cairo-gobject-devel glib2-devel gobject-introspection-devel libxml2-devel
macOS
On macOS, you can install glib and Cairo using HomeBrew (for setup instructions, see http://brew.sh). Once you have a running HomeBrew installation, you can use it to install a native version of cairo:
brew update
brew install cairo glib glib-networking gobject-introspection pkg-config
Building
Normally, you don’t build this package directly, but you embed it into your own project (see ‘Embedding’ below). However, you can build and test this module separately to ensure that everything works. Make sure you have all the prerequisites installed (see above). After that, you can simply clone this repository and build the command line executable (be patient, this will download all the required dependencies and take a while to compile) using
git clone https://github.com/rhx/SwiftCairo.git
cd SwiftCairo
./build.sh
./test.sh
Xcode
On macOS, you can build the project using Xcode instead. To do this, you need to create an Xcode project first, then open the project in the Xcode IDE:
./xcodegen.sh
open Cairo.xcodeproj
After that, use the (usual) Build and Test buttons to build/test this package.
Documentation
You can find reference documentation inside the docs folder.
This was generated using the jazzy tool.
If you want to generate your own documentation, matching your local installation,
you can use the generate-documentation.sh
script in the repository.
Unfortunately, at this stage jazzy only works on macOS (and crashes under Linux), so this will currently only work on a Mac.
Troubleshooting
Here are some common errors you might encounter and how to fix them.
Old Swift toolchain or Xcode
If you get an error such as
$ ./build.sh
error: unable to invoke subcommand: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-package (No such file or directory)
this probably means that your Swift toolchain is too old. Make sure the latest toolchain is the one that is found when you run the Swift compiler (see above).
If you get an older version, make sure that the right version of the swift compiler is found first in your PATH
. On macOS, use xcode-select to select and install the latest version, e.g.:
sudo xcode-select -s /Applications/Xcode.app
xcode-select --install

I was following the Vice-Warden, but, on second thoughts, went after my Lady, being curious to see how she would manage to keep the children out of sight.
I found her holding Sylvie’s hand, and with her other hand stroking Bruno’s hair in a most tender and motherly fashion: both children were looking bewildered and half-frightened.
“My own darlings,” she was saying, “I’ve been planning a little treat for you! The Professor shall take you a long walk into the woods this beautiful evening: and you shall take a basket of food with you, and have a little picnic down by the river!”
Bruno jumped, and clapped his hands. “That are nice!” he cried. “Aren’t it, Sylvie?”
 “Thank you very much,” she said earnestly.
 “Little simpletons!” she muttered to herself, as she marched up to the house. I followed her in.
“Quite so, your Excellency,” the Baron was saying as we entered the Library. “All the infantry were under my command.” He turned, and was duly presented to my Lady.
“A military hero?” said my Lady.  “Well, yes,” he replied, modestly casting down his eyes. “My ancestors were all famous for military genius.”
My Lady smiled graciously. “It often runs in families,” she remarked: “just as a love for pastry does.”
The Baron looked slightly offended, and the Vice-Warden discreetly changed the subject. “Dinner will soon be ready,” he said. “May I have the honor of conducting your Adiposity to the guest-chamber?”
“Certainly, certainly!” the Baron eagerly assented. “It would never do to keep dinner waiting!” And he almost trotted out of the room after the Vice-Warden.
He was back again so speedily that the Vice-warden had barely time to explain to my Lady that her remark about “a love for pastry” was “unfortunate. You might have seen, with half an eye,” he added, “that that’s his line. Military genius, indeed! Pooh!”
“Dinner ready yet?” the Baron enquired, as he hurried into the room.
“Will be in a few minutes,” the Vice-Warden replied. “Meanwhile, let’s take a turn in the garden. You were telling me,” he continued,
as the trio left the house, “something about a great battle in which you had the command of the infantry—”
“True,” said the Baron. “The enemy, as I was saying, far outnumbered us: but I marched my men right into the middle of—what’s that?” the Military Hero exclaimed in agitated tones, drawing back behind the Vice-Warden, as a strange creature rushed wildly upon them, brandishing a spade.
“It’s only the Gardener!” the Vice-Warden replied in an encouraging tone. “Quite harmless, I assure you. Hark, he’s singing! Its his favorite amusement.”
And once more those shrill discordant tones rang out:—
“He thought he saw a Banker’s Clerk
Descending from the bus:
He looked again, and found it was
A Hippopotamus:
‘If this should stay to dine,’ he said,
‘There won’t be mutch for us!’”
Throwing away the spade, he broke into a frantic jig, snapping his fingers, and repeating, again and again,
“There won’t be much for us!
There won’t be much for us!”
Once more the Baron looked slightly offended, but the Vice-Warden hastily explained that the song had no allusion to him, and in fact had no meaning at all. “You didn’t mean anything by it, now did you?” He appealed to the Gardener, who had finished his song, and stood, balancing himself on one leg, and looking at them, with his mouth open.
“I never means nothing,” said the Gardener: and Uggug luckily came up at the moment, and gave the conversation a new turn.
“Allow me to present my son,” said the Vice-warden; adding, in a whisper, “one of the best and cleverest boys that ever lived! I’ll contrive for you to see some of his cleverness. He knows everything that other boys don’t know; and in archery, in fishing, in painting, and in music, his skill is—but you shall judge for yourself. You see that target over there? He shall shoot an arrow at it. Dear boy,”he went on aloud, “his Adiposity would like to see you shoot. Bring his Highness’ bow and arrows!”
Uggug looked very sulky as he received the bow and arrow, and prepared to shoot. Just as the arrow left the bow, the Vice-Warden trod heavily on the toe of the Baron, who yelled with the pain.
“Ten thousand pardons!” he exclaimed. “I stepped back in my excitement. See! It is a bull’s-eye!”
The Baron gazed in astonishment. “He held the bow so awkwardly, it seemed impossible!” he muttered. But there was no room for doubt: there was the arrow, right in the centre of the bull’s-eye!
“The lake is close by,” continued the Vice-warden. “Bring his Highness’ fishing-rod!” And Uggug most unwillingly held the rod, and dangled the fly over the water.
“A beetle on your arm!” cried my Lady, pinching the poor Baron’s arm worse than if ten lobsters had seized it at once. “That kind is poisonous,” she explained. “But what a pity! You missed seeing the fish pulled out!”

“I had always fancied,” the Baron faltered, “that cod were salt-water fish?”
“Not in this country,” said the Vice-Warden. “Shall we go in? Ask my son some question on the way any subject you like!” And the sulky boy was violently shoved forwards, to walk at the Baron’s side.
“Could your Highness tell me,” the Baron cautiously began, “how much seven times nine would come to?”
“Turn to the left!” cried the Vice-Warden, hastily stepping forwards to show the way—so hastily, that he ran against his unfortunate guest, who fell heavily on his face.
“So sorry!” my Lady exclaimed, as she and her husband helped him to his feet again. “My son was in the act of saying ‘sixty-three’ as you fell!”
The Baron said nothing: he was covered with dust, and seemed much hurt, both in body and mind. However, when they had got him into the house, and given him a good brushing, matters looked a little better.
Dinner was served in due course, and every fresh dish seemed to increase the good-humour of the Baron: but all efforts, to get him to express his opinion as to Uggug’s cleverness, were in vain, until that interesting youth had left the room, and was seen from the open window, prowling about the lawn with a little basket, which he was filling with frogs.
“So fond of Natural History as he is, dear boy!” said the doting mother. “Now do tell us, Baron, what you think of him!”
“To be perfectly candid, said the cautious Baron, “I would like a little more evidence. I think you mentioned his skill in—”
“Music?” said the Vice-Warden. “Why, he’s simply a prodigy! You shall hear him play the piano? And he walked to the window. “Ug—I mean my boy! Come in for a minute, and bring the music-master with you! To turn over the music for him,” he added as an explanation.
Uggug, having filled his basket with frogs, had no objection to obey, and soon appeared in the room, followed by a fierce-looking little man, who asked the Vice-Warden “Vot music vill you haf?”
“The Sonata that His Highness plays so charmingly,” said the Vice-Warden. “His Highness haf not—” the music-master began, but was sharply stopped by the Vice-warden.
“Silence, Sir! Go and turn over the music for his Highness. My dear,” (to the Wardeness) “will you show him what to do? And meanwhile, Baron, I’ll just show you a most interesting map we have—of Outland, and Fairyland, and that sort of thing.”
By the time my Lady had returned, from explaining things to the music-master, the map had been hung up, and the Baron was already much bewildered by the Vice-Warden’s habit of pointing to one place while he shouted out the name of another.
My Lady joining in, pointing out other places, and shouting other names, only made matters worse; and at last the Baron, in despair, took to pointing out places for himself, and feebly asked “Is that great yellow splotch Fairyland?”
“Yes, that’s Fairyland,” said the Vice-warden: “and you might as well give him a hint,” he muttered to my Lady, “about going back to-morrow. He eats like a shark! It would hardly do for me to mention it.”
His wife caught the idea, and at once began giving hints of the most subtle and delicate kind. “Just see what a short way it is back to Fairyland! Why, if you started to-morrow morning, you’d get there in very little more than a week!”
The Baron looked incredulous. “It took me a full month to come,” he said.

The Baron looked appealingly to the Vice-warden, who chimed in readily.
All this time the Sonata was pealing through the room. The Baron could not help admitting to himself that it was being magnificently played: but he tried in vain to get a glimpse of the youthful performer. Every time he had nearly succeeded in catching sight of him, either the Vice-Warden or his wife was sure to get in the way, pointing out some new place on the map, and deafening him with some new name.
He gave in at last, wished a hasty good-night, and left the room, while his host and hostess interchanged looks of triumph.
“Deftly done!” cried the Vice-Warden. “Craftily contrived! But what means all that tramping on the stairs?” He half-opened the door, looked out, and added in a tone of dismay, “The Baron’s boxes are being carried down!”
“And what means all that rumbling of wheels?” cried my Lady. She peeped through the window curtains. “The Baron’s carriage has come round!” she groaned.

And still the noble Sonata went pealing through the room: but it was Arthur’s masterly touch that roused the echoes, and thrilled my very soul with the tender music of the immortal ‘Sonata Pathetique’: and it was not till the last note had died away that the tired but happy traveler could bring himself to utter the words “good-night!” and to seek his much-needed pillow.


Installation¶
$ pip3 install ansible-bender
If you are brave enough, please install bender directly from git master:
$ pip3 install git+https://github.com/ansible-community/ansible-bender
If pip3
command is not available on your system, you can run pip like this:
$ python3 -m pip install ...
Requirements (host)¶
Pip takes care of python dependencies, but ansible-bender also requires a few binaries to be present on your host system:
-
Ansible needs to be built against python 3
Python 3.6 or later (python 3.5 or earlier are not supported and known not to be working)
Last two requirements can be pretty tough: you can always run bender in a privileged container.
 Just install the packages and you are good to go. This is the preferred way — buildah and podman are much more efficient when using the in-kernel overlay filesystem and you will encounter less issues than with the rootless mode.
On the other hand, if you want to utilize the rootless mode, you need to set up the UID mapping. It is documented in podman’s documentation. All you need to do is to add an entry into /etc/subuid and /etc/subgid:
$ sudo sh -c "printf \"\n$(whoami):100000:65536\n\" >>/etc/subuid"
$ sudo sh -c "printf \"\n$(whoami):100000:65536\n\" >>/etc/subgid"
You should consult podman’s troubleshooting guide if you are running into issues.
Requirements (base image)¶
python interpreter — ansible-bender will try to find it (alternatively you can specify it via
--python-interpreter
).It can be python 2 or python 3 — on host, you have to have python 3 but inside the base image, it doesn’t matter — Ansible is able to utilize python 2 even if it’s invoked with python 3 on the control machine.
Requirements (Ansible playbook)¶
None.
Bender copies the playbook you provide so that it can be processed. hosts
variable is being overwritten in the copy and changed to the name of the
working container — where the build happens. So it doesn’t matter what’s the
content of the hosts variable.

Austin Powers: The Spy Who Shagged Me.
Starring Mike Myers and Heather Graham Directed By Jay Roach Running Time: 1 hour 35 minutes
(New Line Cinema)
When the original Austin Powers was released in cinemas around three years ago, the screening I attended had about five people in total watching the film. The Spy Who Shagged Me, (TSWME) the inevitable sequel, had about thirty times that figure, a testament to Austin's video popularity. The hip spy from the sixties returns to celluloid in this colourful, largely funny sequel to 'International Man of Mystery.' Mike Myers plays the titular Austin Powers, now living in the nineties with Vanessa Kensington. Unfortunately, Austin's mojo is stolen by the evil Doctor Evil (Myers again). Austin must return to the sixties to regain his mojo from the evil doctor, and must also stop Dr. Evil from blowing up the earth with a large "laser." He teams up with sexy CIA agent Felicity Shagwell (Graham) and sets off on his rather silly quest.
Mike Myers always seems to be lazy when making a sequel, usually by recycling jokes from the original film to a less funnier extent.  However, although rather hit and miss, TSWME has enough laughs to keep the film running until it decides to end just before it runs out of steam. The cast, largely made up by Myers who plays three roles, is energetic and fun. Robert Wagner repeats his brief part from the original movie, before being replaced by Rob Lowe, who basically plays Robert Wagner rather well. Mindy Sterling is fun as the German scarebag Frau Farbissina, and Seth Green returns as Dr. Evils estranged son Scott. Heather Graham is only slightly disappointing as Felicity, although this is largely to do with the fact that her character is intensely shallow, little more than a sex object. She looks great, but is more than a little empty. Finally, Verne Troyer is rather good as Dr. Evils smaller clone, Mini-Me, although the character is largely wasted until a funny fight between him and Austin near the end of the movie.
The gags are largely good, stand outs include a funny tent gag, and a funny performance of 'Just the Two of Us.' The film seems to have benefited from a larger budget, with a much sharper, funnier look than the first film. It all looks like a large set however, and clearly not filmed much in England (as Austin points out.) The plot is full of inconsistencies, but Myers and Co. desperately try to cover this up by telling the audience to 'go with it,' which seems like a cop out. Vanessa Kensington's fate, for example, is badly handled and then thrown away.
But although the set pieces are funny and some of the one-liners sharp, there are some parts of TSWSM that just don't work. 'Fat Bastard,' a Scottish assassin who weighs a metric ton, is largely unfunny, although he gets one of the best lines near the end of the movie. Mini-Me is never fully used. Austin is also curiously underused, and Dr. Evil gets far more screen time. This is largely a good thing however, as Dr. Evil is much funnier than Austin Powers, which is a bit odd seeing as Austin is meant to be the star. But all the gags are delivered with a likeable charm, so even the ones that don't work can get a smirk. There are some dead bits, but the belly laughs that follow usually compensate. The film also delves into toilet humour far more often than it's predecessor, and this gags aren't as funny or original as the rest of the films jokes.
Overall, TSWSM is short and sweet enough to be good for some light comic relief. It will keep you laughing, and Mike Myers charm practically flows from the screen. There's enough effort to make this film work, and it is a worthy enough successor to the already cult movie. It won't get you thinking, but Austin Powers will certainly get you laughing.

gaargh I can't find
example (P Q : Prop) : (¬ Q → ¬ P) → (P → Q) := sorry
I understand it will be classical.something. I know mt
(the other direction). I've looked in logic.basic
but I couldn't find it (maybe I missed it). I want to find this with #find
and not bother people here. But #find (¬ _ → ¬ _) → (_ → _)
doesn't work for me. I want this to be easier. Help!
how do you use #find? #find doesn't work for me at all..
you have to import tactic.find
of course this is going to be in logic.basic
looks like it is not_imp_not
it's a biconditional, which is why find didn't find it the way you stated it
it's not classical.something because it has a decidability assumption
I didn't know whether to look in logic.basic or core. I've run into several issues like this recently. I am doing my undergraduate example sheets again, with an extra year of hindsight. Now I understand what "should be somewhere", so instead of proving things like this myself I try to find them. If I can guess the name then I'm in business, but my guesses failed me this time. Not knowing whether I should search for -> or <->, and not knowing where to look, doesn't help (I am slow at learning where things are because I can't pick stuff up as quickly as when I was younger -- I need machine assistance here ideally).
None of
#find (¬ _ → ¬ _) → (_ → _) #find (¬ _ → ¬ _) ↔ (_ → _) #find (_ → _) ↔ (¬ _ → ¬ _)
give me anything. Why does the middle one fail? I have logic.basic
imported.
not_imp_not : ∀ {a b : Prop} [_inst_1 : decidable a], ¬a → ¬b ↔ b → a
What is the philosophy behind calling this not_imp_not
?
I really did try before I asked. It was the decidable v classical which caught me out.

Hack 12 Use Multiple Screens on One Terminal
Running a graphical environment is great. You can have numerous applications and utilities running, and you can interact with all of them at the same time.  "After all," they say, "you can only do one thing at a time and don't get the same information and control that you have in a desktop environment." It's true; they do say those things. (I am curious to know who they are, however.) It's also true that the utility of a graphical environment diminishes when you need to administer machines remotely. Do you really want to squander network bandwidth just to maintain a GUI session? Here are some more questions to ask yourself regarding remote administration:
You are indeed a poor soul if you've reconciled yourself to the standard ssh login without any hope of resolving these questions. But all is not lost—the solution is screen. 1.13.1 What Is screen?screen is a terminal screen window manager. That means you can use a console and run multiple terminals at the same time. The fancy term for this ability is multiplexing. Getting and installing screen is straightforward using the ports facility: # cd /usr/ports/misc/screen # make install clean I'm working with Version 4.00.01 (FAU) 18-Sep-03. 1.13.2 Getting Startedscreen has many options, settings, and commands. Although we'll attempt to address the major features, the definitive reference is, of course, the manpage. There are three methods of command-line invocation:
1.13.3 Multitasking with screenThe best way to understand screen's power is to give you an example of how you can take advantage of it. Suppose you are sitting at workstation alpha. You want to access your machine, bravo, to download and compile the latest PostgreSQL source code. Log into host bravo as user charlie using SSH: % ssh -l charlie bravo Invoke screen. If you give it a session name, with the -s flag, you can address this session by name. This will pay off shortly. % screen -s A Go ahead and download the source code now: % ftp ftp://ftp3.ca.postgresql.org/pub/source/v7.4/postgresql-7.4.tar.gz <IP_ADDRESS> Using windows with screenSo far, this has no advantage over a normal SSH login. Yet suppose you need to send some email while you're downloading. Instead of putting the download into the background, create another screen window with the key sequence C-a c. This symbolizes that the Ctrl key is pressed with the lowercase letter a and then, after releasing them, you press a second key, in this case c. At this point the console will go blank. You'll be presented with a second window. Use your favorite email client to compose your message. <IP_ADDRESS> Switching between windowsYou'll probably want to switch between the download and mailer windows. Cycle forward in the window list with C-a n. Cycle backward with C-a p, although you'll likely see no difference with two windows. <IP_ADDRESS> Splitting windowsBeing the efficient person that you are, you'd like to compile the source code as soon as it has downloaded. Even though you haven't completed your email, go back to the original window and extract the tarball: % tar -xzpvf postgresql-7.4.tar.gz Wise administrators read the INSTALL file to make sure all the correct options are invoked. It'd be very handy to be able to read the instructions as you compose the configure command in the same console. screen comes to the rescue here, too: split the window horizontally, running configure in the top half and reading the documentation in the bottom half. Type C-a S to split the screen, where the S is uppercase. You should see a wide horizontal bar in the middle of the screen. The top window will show whatever existed when you split the window. You'll also see the window's ID on the left side of the middle bar, along with the name of the shell. The bottom window doesn't yet have a shell running. Set the focus to the other window with C-a Tab. Create a new window with C-a c, as usual. Notice that the window has the ID of 2 (shown in the bottom lefthand corner); that's because the email window that you created after starting the download has the ID of 1. <IP_ADDRESS> Better window switchingTo list all windows associated with this session, use the command C-a ". If cycling through windows is onerous, you can also switch between windows by ID. For example, C-a ' 1 will go to window 1. Be prepared for a little confusion because the screen remains split and now shows the window of your choice in the currently focused window. You can quite easily show the same window in both the top and bottom halves. Enter window 0 with C-a ' 0, and extract the tarball into its own directory. Enter window 2 with C-a ' 2, and navigate to the uppermost directory of the source code to read the INSTALL file. <IP_ADDRESS> Naming windowsID numbers identify windows pretty well, but I prefer to use names of my own choosing. Change a window's name with the command C-a A. For example, C-a A email, C-a A source, and C-a A doc seem like a big improvement for the currently active windows. Now, listing the active windows with C-a " will show the following: NUM NAME 0 source 1 email 2 doc At this point, you have one screen session with three windows. Your terminal is split such that it shows two windows at the same time. 1.13.4 Attaching and DeattachingSuppose you are called away from the workstation in the middle of a sensitive operation (that is, you haven't yet sent your email). Type C-a x to protect your session. Depending on your configuration, you will either input a password for the screen or use the default account password. Now suppose you don't return to your workstation. What do you do? You can ssh into bravo from a new location and attach to your existing screen session with screen -dr A. Remember, A was the name of the screen session.  Type the command C-a k in the email window. With that business finished, scroll back through the INSTALL text file to find interesting configuration switches. You could retype them, but screen has a perfectly capable copy mode. Type C-a ESC. Use the cursor keys to navigate to the portions of the document you want to copy. Hit the space bar to mark the beginning of the text to copy. Scroll around to the end of the text with the cursor keys. The current selection will display in reverse video. When you're satisfied, hit the space bar to copy the current selection into the buffer. Switch to the source window and use C-a ] to paste the copied text. You don't need the doc window anymore, so switch into it and either exit the shell or use the key sequence C-a k to kill it. You could also merge the split screens together with the key sequence C-a X. Once you've started compiling, you can close the terminal but leave the session active by detaching it; just type C-a d. One of the nice features about detaching the screen is that it is done automatically if you lose connection with the server, so you won't lose your session. You can reattach to the session later from the same location or from another workstation altogether. 1.13.5 Additional FeaturesThese are only the basics of what screen can do. Here's a quick listing of other features you might enjoy:
You can control all of these features with the .screenrc resource file. See man screen for details. 1.13.6 See Also

Tests the audio-level property for nested audio elements and clamping of audio-level.
The test consists of 6 subtests. When each audio sub-test is executed a corresponding rect will turn blue. When each audio sub-test is finished the corresponding rect will turn gray again. For this test to pass, all subtests must have a green rectangle next to them. The audio must also be heard to pass this test. If the user agent does not support the WAV media format, the test is still a pass.
The 1st subtest has an audio-level = 1. To pass this subtest the audio must be played at the system volume.
The 2nd subtest has an audio-level = 2. To pass this subtest the audio must be played at the system volume.
The 3rd subtest has an audio element with an audio-level = 2. Within the audio element there is a child audio element with an audio-level = 0.5. The source audio is the child audio element. To pass this subtest the audio must be played at 1/2 the system volume.
The 4th subtest has an audio element with an audio-level = 0.5. Within the audio element there is a child audio element with an audio-level = 2. The source audio is the child audio element. To pass this subtest the audio must be played at 1/2 the system volume.
The 5th subtest has three audio elements. The first audio element has an audio-level = 0.5 and is the parent audio element. The second audio element has an audio-level = 2 and is a child to the first audio element. The third audio element has an audio-level = 0.5 and is a child to the second audio element. The source audio is third audio element. To pass this subtest the audio must be played at 1/4 the system volume.
The 6th subtest has four audio elements. The first audio element has an audio-level = to the audio level of the 3rd audio element (0.5). The second audio element references an audio element from another subtest with an audio-level of 2. The second audio element is a child of the first audio element. The third audio element has an audio-level = 0.5 and is a child of the second audio element. The fourth audio element has an audio-level of 2 and is a child of the third audio element. The source audio is the fourth audio element. To pass this subtest the audio must be played at 1/4 the system volume.

Is there such a thing as too much reflection?
What is grid based design?
My understanding is that this a convention used to create easily customizable structures for the elements of a website using a certain number of columns. This kind of design should also help the user to understand and navigate easily through the different elements.
Whats all the hype about responsive webpages?
The cool thing about this new trend is that you would be able to create a single webpage that can look good on lots of different devices ditching the good old mobile pages and other high maintenance stuff. I mean, how cool is that right?
What is semantic structure?
On HTML this means using the elements provided in the structure they were intended to so they have internal coherence. I believe the equivalent would be to use the correct structure to write a newspaper article for example: you wouldn't put the title in the middle of a paragraph and so forth.
Interesting facts
This was just something curious I found (and perhaps slightly annoying): How silly is it that most of the CSS Zen Garden are actually images instead of CSS styling? I'll go with VERY silly. I basically learned that you can do a lot of things with Photoshop *facepalm*.

| net.corda.testing.node.MockNetwork |
A mock node brings up a suite of in-memory services in a fast manner suitable for unit testing. Components that do IO are either swapped out for mocks, or pointed to a Jimfs in memory filesystem or an in memory H2 database instance. |
| net.corda.testing.node.MockNetworkNotarySpec |
The spec for a notary which will used by the MockNetwork to automatically start a notary node. This notary will become part of the network parameters used by all the nodes. |

| net.corda.testing.node.MockNodeParameters |
Immutable builder for configuring a StartedMockNode or an UnstartedMockNode via MockNetwork.createNode and MockNetwork.createUnstartedNode. Kotlin users can also use the named parameters overloads of those methods which are more convenient. |
| net.corda.testing.node.MockServices |
An implementation of ServiceHub that is designed for in-memory unit tests of contract validation logic. It has enough functionality to do tests of code that queries the vault, inserts to the vault, and constructs/checks transactions. However it isn't enough to test flows and other aspects of an app that require a network. For that you should investigate MockNetwork. |
| net.corda.testing.driver.NodeHandle |
A base interface which represents a node as part of the driver dsl, extended by InProcess and OutOfProcess |

The strings accepted by this class are a minor variant of Yaml and can be easily typed at a command line. Intended use cases include things like the Corda shell, text-based RPC dispatch, simple scripting and so on. |
| net.corda.testing.node.TestClock |
A Clock that can have the time advanced for use in testing. |
| net.corda.testing.node.TestCordapp |

Modifying the runtime environment
You can use internal extensions to modify the runtime process. Internal extensions are not separate processes—they run as part of the runtime process.
Lambda provides language-specific environment variables that you can set to add options and tools to the runtime. Lambda also provides wrapper scripts, which allow Lambda to delegate the runtime startup to your script. You can create a wrapper script to customize the runtime startup behavior.
Language-specific environment variables
Lambda supports configuration-only ways to enable code to be pre-loaded during function initialization through the following language-specific environment variables:
-
JAVA_TOOL_OPTIONS
– On Java 11 and Java 8 (java8.al2
), Lambda supports this environment variable to set additional command-line variables in Lambda. This environment variable allows you to specify the initialization of tools, specifically the launching of native or Java programming language agents using theagentlib
orjavaagent
options. -
NODE_OPTIONS
– On Node.js 10x and above, Lambda supports this environment variable. -
DOTNET_STARTUP_HOOKS
– On .NET Core 3.1 and above, this environment variable specifies a path to an assembly (dll) that Lambda can use.
Using language-specific environment variables is the preferred way to set startup properties.
Example: Intercept Lambda invokes with javaagent
The Java virtual machine (JVM) tries to locate the class that was specified with the
javaagent
parameter to the JVM, and invoke its premain
method before the application's entry point.
The following example uses Byte BuddyAgent
class intercepts
every call of the handleRequest
method made to the RequestStreamHandler
import com.amazonaws.services.lambda.runtime.RequestStreamHandler; import net.bytebuddy.agent.builder.AgentBuilder; import net.bytebuddy.asm.Advice; import net.bytebuddy.matcher.ElementMatchers; import java.lang.instrument.Instrumentation; public class Agent { public static void premain(String agentArgs, Instrumentation inst) { new AgentBuilder.Default() .with(new AgentBuilder.InitializationStrategy.SelfInjection.Eager()) .type(ElementMatchers.isSubTypeOf(RequestStreamHandler.class)) .transform((builder, typeDescription, classLoader, module) -> builder .method(ElementMatchers.nameContains("handleRequest")) .intercept(Advice.to(TimerAdvice.class))) .installOn(inst); } }
The agent in the preceding example uses the TimerAdvice
method. TimerAdvice
measures how many milliseconds are spent with the method call and logs the method
time and details, such as name
and passed arguments.
import static net.bytebuddy.asm.Advice.AllArguments; import static net.bytebuddy.asm.Advice.Enter; import static net.bytebuddy.asm.Advice.OnMethodEnter; import static net.bytebuddy.asm.Advice.OnMethodExit; import static net.bytebuddy.asm.Advice.Origin; public class TimerAdvice { @OnMethodEnter static long enter() { return System.currentTimeMillis(); } @OnMethodExit static void exit(@Origin String method, @Enter long start, @AllArguments Object[] args) { StringBuilder sb = new StringBuilder(); for (Object arg : args) { sb.append(arg); sb.append(", "); } System.out.println(method + " method with args: " + sb.toString() + " took " + (System.currentTimeMillis() - start) + " milliseconds "); } }
The TimerAdvice
method above has the following dependencies.
*'com.amazonaws'*, *name*: *'aws-lambda-java-core'*, *version*: *'1.2.1'* *'net.bytebuddy'*, *name*: *'byte-buddy-dep'*, *version*: *'1.10.14'* *'net.bytebuddy'*, *name*: *'byte-buddy-agent'*, *version*: *'1.10.14'*
After you create a layer that contains the agent JAR, you can pass the JAR name to the runtime's JVM by setting an environment variable.
JAVA_TOOL_OPTIONS=-javaagent:"/opt/ExampleAgent-0.0.jar"
After invoking the function with {key=lambdaInput}
, you can find the following line in the
logs:
public java.lang.Object lambdainternal.EventHandlerLoader$PojoMethodRequestHandler.handleRequest (java.lang.Object,com.amazonaws.services.lambda.runtime.Context) method with args: {key=lambdaInput}, lambdainternal.api.LambdaContext@4d9d1b69, took 106 milliseconds
Example: Adding a shutdown hook to the JVM runtime process
When an extension is registered during a Shutdown
event, the runtime process gets up to
500 ms to handle graceful shutdown. You can hook into the runtime process, and when
the JVM begins its shutdown
process, it starts all registered hooks. To register a shutdown hook, you must register as an extension. You do not need to explicitly
register for the Shutdown
event, as that is automatically sent to the runtime.
import java.lang.instrument.Instrumentation; public class Agent { public static void premain(String agentArgs, Instrumentation inst) { // Register the extension. // ... // Register the shutdown hook addShutdownHook(); } private static void addShutdownHook() { // Shutdown hooks get up to 500 ms to handle graceful shutdown before the runtime is terminated. // // You can use this time to egress any remaining telemetry, close open database connections, etc. Runtime.getRuntime().addShutdownHook(new Thread(() -> { // Inside the shutdown hook's thread we can perform any remaining task which needs to be done. })); } }
Example: Retrieving the InvokedFunctionArn
@OnMethodEnter static long enter() { String invokedFunctionArn = null; for (Object arg : args) { if (arg instanceof Context) { Context context = (Context) arg; invokedFunctionArn = context.getInvokedFunctionArn(); } } }
Wrapper scripts
You can create a wrapper script to customize the runtime startup behavior of your Lambda function. A wrapper script enables you to set configuration parameters that cannot be set through language-specific environment variables.
Invocations may fail if the wrapper script does not successfully start the runtime process.
The following Lambda runtimes support wrapper scripts:
-
Node.js 14.x
-
Node.js 12.x
-
Node.js 10.x
-
Python 3.8
-
Ruby 2.7
-
Java 11
-
Java 8 (
java8.al2
) -
.NET Core 3.1
When you use a wrapper script for your function, Lambda starts the runtime using your script. Lambda sends to your script the path to the interpreter and all of the original arguments for the standard runtime startup. Your script can extend or transform the startup behavior of the program. For example, the script can inject and alter arguments, set environment variables, or capture metrics, errors, and other diagnostic information.
You specify the script by setting the value of the AWS_LAMBDA_EXEC_WRAPPER
environment variable
as the file system path of an executable binary or script.
Example: Create and use a wrapper script with Python 3.8
In the following example, you create a wrapper script to start the Python interpreter
with the -X
importtime
option. When you run the function, Lambda generates a log entry to show the duration
of the
import time for each import.
To create and use a wrapper script with Python 3.8
-
To create the wrapper script, paste the following code into a file named
importtime_wrapper
:#!/bin/bash # the path to the interpreter and all of the originally intended arguments args=("$@") # the extra options to pass to the interpreter extra_args=("-X" "importtime") # insert the extra options args=("${args[@]:0:$#-1}" "${extra_args[@]}" "${args[@]: -1}") # start the runtime with the extra options exec "${args[@]}"
-
To give the script executable permissions, enter
chmod +x importtime_wrapper
from the command line. -
Deploy the script as a Lambda layer.
-
Create a function using the Lambda console.
-
Open the Lambda console
. -
Choose Create function.
-
Under Basic information, for Function name, enter
wrapper-test-function
. -
For Runtime, choose Python 3.8.
-
Choose Create function.
-
-
Add the layer to your function.
-
On the configuration page, choose Layers.
-
Choose Add a layer.
-
Under Choose a layer, choose the Name and Version of the compatible layer that you created earlier.
-
Choose Add.
-
-
Add the code and the environment variable to your function.
-
In the function code editor, paste the following function code:
import json def lambda_handler(event, context): # TODO implement return { 'statusCode': 200, 'body': json.dumps('Hello from Lambda!') }
-
Choose Save.
-
Under Environment variables, choose Manage environment variables.
-
Choose Add environment variable.
-
For Key, enter
AWS_LAMBDA_EXEC_WRAPPER
. -
For Value, enter
/opt/importtime_wrapper
. -
Choose Save.
-
-
To run the function, choose Test.
Because your wrapper script started the Python interpreter with the
-X importtime
option, the logs show the time required for each import. For example:... 2020-06-30T18:48:46.780+01:00 import time: 213 | 213 | simplejson 2020-06-30T18:48:46.780+01:00 import time: 50 | 263 | simplejson.raw_json ...

Note that relative imports work only within the current source root. You cannot relatively
import a package from another source root. So, absolute imports are preferred
if the current location of the import statement may change.

‘Nothing special about Mnangagwa, Chamisa’
by Staff ReporterPROMINENT pro-democracy campaigner Briggs Bomba has urged Zimbabweans to stop treating President Emmerson Mnangagwa and his MDC rival, Nelson Chamisa as demigods.
Bomba, who is Citizens Manifesto convener, was speaking at the movement’s review of their National People’s Conference the group held last month.
The civic leader said Zimbabweans were too preoccupied with misconceptions the leaders of the country’s two most dominant political parties were the beginning and end of Zimbabwe’s political, economic and social problems.
“There is a misunderstanding that for us to move forward, the two should solve our problems.
“Citizens must understand that there is nothing special about President Emmerson Mnangagwa and MDC President Nelson Chamisa, nothing at all.
“At one time, they both walked barefoot, the other in Mberengwa and the other in Gutu there.
“We should stop treating them as demigods and let them realise they are there to serve the interests of those who voted them into power; they serve us.”
His comments follow growing calls by churches and ordinary Zimbabweans the two should meet and try to hammer out a lasting solution to the myriad problems affecting the country.
Bomba is expected to lead a diverse team of members from the Citizens’ Manifesto to meet Mnangagwa in the coming months.
He said there was need for the Zimbabwean electorate to introspect and realise the continuous mistakes they were making in voting for promises rather than results.
“We cannot continue making the same mistake of voting for politicians who continue to promise ‘I will do this for you’.
“We need to start voting for community leaders who have proof that they have done something for their communities,” he said.
Bomba said his group shall also be meeting Chamisa after its discussion with Mnangagwa.
He added, “We would really have loved to bring the two into a single room but we have decided not to push our luck and will be meeting ED, Chamisa and POLAD members separately.”
POLAD, the so-called Political Actors Dialogue, is a forum created by President Mnangagwa for him and the 22 politicians who contested him in the 2018 presidential election.
The platform has often been dismissed as useless as it also brings together politicians with a very tiny following in the country.

Thursday Nights at SRCCON
by Dan Sinker
Evenings at conferences can be tough. After spending a day attending keynotes and panels, the people you were hoping to run into are suddenly nowhere to be found. You heard something about a sponsor’s party at a restaurant near the Hyatt–or was it the Hilton–and there are those folks from the panel earlier who invited you to dinner. Maybe you’ll just go back to your room and probably folks will end up at the hotel bar at some point, which isn’t the best because you don’t drink, but you will see people so I guess so.
We’ve all been there. So in designing SRCCON, we include evening activities open to all participants. And more than just giving people something to do, we think about how our Thursday night activities contribute to the entire arc of SRCCON. A hands-on conference like SRCCON is intense, and we ask all participants to bring their whole selves to the event—and so, after a day of intense sessions, it’s important to let participants share the non-work side of themselves with the community, and to focus on the “life” side of the work/life balance.
Our first SRCCON had four rooms in the evening, one for tabletop games, one for lightning talks, one for hacking, and a “foodie” room for exchanging homemade eats (which turned into a beer exchange–more on that in a second). This year, our third, we greatly expanded the options for the evening and ended up keeping the vast majority of our 300 participants engaged. Here’s what we did and how it worked.
A Diverse Group Requires Diverse Activities
The key to keeping people engaged in the evening is understanding that not everyone wants to spend their nights the same way. That’s why just having a bar available, or a huge room for lightning talks, or throwing a party doesn’t work. Some people want to chill, others want to chat, and many need some kind of intermediary to engage with new people or try new things. So for SRCCON evenings, we offered a lot of varied activities, none of which required attendees to stick with a single thing all night. You could jump from one thing to the next, or go out and come back. We had a clear schedule with times and locations listed for everything, and we made sure it happened on time. Here’s what we offered:
All night activities
- Ice Cream: We had an ice cream truck parked outside that accepted your SRCCON badge for free ice cream. This gave people an opportunity to get some fresh air and chat, while also offering a sugar rush and a nice change of pace from catered meals.
- Game Room: This has become a bit of a SRCCON signature, but we’ve always made space for people to engage in board games and card games throughout the evening at SRCCON. We’ve found that getting to know people over a (mostly) friendly game of Coup or Exploding Kittens is a great, easy, way to have some fun.
- DNC Viewing: Sometimes you have to leave some room for an emergent activity. As it turned out, the final night of the Democratic National Convention was happening the same evening we were running our activities, so we chose a room with a big TV and set it aside for watching the DNC (as it turned out, this space was full to capacity the entire evening).
- Quiet Space: We know that sometimes people just need to get some email checked, or get a patch pushed up to production, or just want time to check in with family. So we set aside a room off from the bustle of the rest of the event so that people could get away and have some screen time.
Time-blocked activities:
- Hobby Workshops: We tried a crafting room at SRCCON twice and both times there was never enough participants to make it come together. Yet, letting people share their hobbies still seemed like a good idea, so we tried it differently this time: We solicited hobby ideas from participants a few weeks out, and the ideas we selected (mainly ones that could be pulled off in an hour time block), we bought supplies for, eliminating the fact that not everyone rolls into a conference with, say, knitting needles at hand. As a result, our Hobby workshops (which included knitting, origami, funkstyle dance, and… Olympic-style weightlifting) were all well attended, and people really learned something.
- Conversations: Sometimes people just want to talk but having something to talk about is nice so, while soliciting ideas for Hobby Workshops, we also asked people to pitch ideas for hour-long conversations. The one requirement was that they couldn’t be about work. We ended up hosting conversations about art and design and home recording.
- A guided tour: It’s important that you get an opportunity to engage in a host city at a conference, and so for two years now we’ve had evening walks guided by a local journalist. This year, in Portland, we had a journalist from the Oregonian who was able to talk about city politics while taking about 50 people around downtown Portland.
- Lightning Talks: Finally, like many conferences, we host lightning talks. These five-minute-long presentations are hugely popular and if you want to sit and listen to people being briefly brilliant, they’re hard to beat. However, we’ve seen enough conferences where the lightning talks become so popular that they fill a thousand-person room. We purposefully keep the lightning talks less formal and run multiple things opposite them so that they’re just an offering, not the offering.
What this all meant was that at any time on Thursday evening, there were about eight different things to choose from. This was a dramatic increase from previous years pushed by both attendance numbers (more than double year one), but also by feedback we solicit and build from every year.
Participatory Inputs
Offering this much programming in the evening is a fine balance between event design and user-driven ideas. In addition to soliciting ideas for Hobby Workshops and Conversations, much of what was on offer came through suggestions or ideas from SRCCON attendees a few weeks in advance. We have an etherpad [link] that people listed games they were going to bring for the game room, the attendees that organized the lightning talks could put a link to their own submission form, and other people could list ideas for the evening (or at other points in the two days of SRCCON).
Budget
So, how expensive is it to run a full slate of activities in the evening? Not extraordinarily so. The space rental covered us until 10pm, so as long as we got everyone out by 9:30 or so (so we had time to reset the rooms), we were good there. We believe in feeding people well at SRCCON, so dinner was always going to happen and was by and large the biggest expense but was wrapped into our overall catering cost. Ice Cream was next, running about $1000 to cover everyone in attendance (we ended up giving away about 350 scoops). Our craft sessions were each given a $100 budget, but we ended up only spending about $150 total across the sessions. Oh, and we bought at $30 Chromecast to stream the DNC (which actually could never get on the WiFi so someone donated their laptop).
Partners
We heard from attendees was that they had partners coming to Portland with them, and that they wanted to include them in some way, if possible. Because SRCCON ticketing is in such demand, we couldn’t simply give partners access to the full slate of SRCCON, but we did make a partner ticket (sold at cost) available for the evening activities. These tickets gave partners full access to our dinner and all activities in the evening (even the free ice cream). We had about 10 people take us up on it, and every partner attended for at least some of the evening.
Alcohol
We know that most conferences put a real focus on drinking at night. Every year at SRCCON we’ve been reducing that focus. Year one we offered an open bar with beer and wine, but we also had a “foodie” room that got a little more beer-soaked than we would have hoped. Year two, we gave every attendee two drink tokens (and cut out the beer exchange). This year, we only offered one. And you know what? It was fine. Folks that wanted more bought another beer. Folks that wanted something else, their token was good for that too. (And our tokens were custom-printed wood, so they made a nice souvenir for folks who just kept them.)
In addition, from previous' years feedback, we made sure that we had a nearby Alcoholics Anonymous meeting location listed on our website alongside a description of Thursday night activities, so that that was an option for anyone that needed a meeting. That involved looking up the meeting and double-checking via phone to make sure theonline meeting information was up-to-date and accurate.
Safety
The safety of participants in SRCCON is something we take very seriously. Our Code of Conduct, and the internal enforcement plan we have for it, doesn’t just apply to the conference day, but the night as well. That means that we expect our participants to abide by the Code during our Thursday evening activities as well as whatever they get up to after the building closed (10pm). We kept shifts on our shared phone number for our help line to ensure that if there was a problem late, someone would be able to field it. Thankfully, we didn’t have any issues reported, but we were ready if we did.
***
When we plan SRCCON, we think through the full two days of the conference. Our Thursday night activities–almost all kept light and fun–are a key part of that approach. We know that not every conference can afford it, or that some venues require everyone to stick to a normal 9-5 schedule, but thinking about the whole of the conference experience, from the beginning to the very end, and all points in between, makes a real difference in the way the entire event feels and runs.

As with everything else in Ruby, Classes are Objects. What this means at the most basic level, is that Classes can be created as need arises to deal with just about anything you'd consider an object in real life.
It seems that the majority of Objects we've created in DBC thus far have been *processors* - they generate data and process that data (and yes, the data has been very thin... so far). Data, of course, exists in the Ruby environment as an Object just as the machinery to process it. So, for example if you have an array of data that is context-specific (a credit card number, a Bingo call, etc) one can create a Class designed specifically with the necessary machinery to deal with that data.
Let's take an example that I'm fairly adept at: Data Management. In this example we'll create a simple inventory management system for a video game store. Our data will be stored in a Hash (which seems to me to be the closest thing to a database that I've seen thus far at DBC), and using a few methods from the standard Ruby library, we'll manage our vast inventory of, say... 2 games? :)
First off when creating a class, you'll want to create an initilizer. Basically, what we have to understand is that when you're creating a class, you're going to be working with it as an instance of that object. That means, upon its creation it has to have some parameters. In the case of our game store inventory machine, let's initialize it with some basic data: an array of games avaiable, and an array that we can use to interpret indeces within the games dataset:
class GameInventory
def initialize
@games_table = %w[title publisher metacritic release_year available_on inventory price]
@games = [["Dark Souls II", "Bandai Namco Games", 91, 2014, "PC, PS3, Xbox 360", 5, 35.00],
["Hearthstone: Heroes of Warcraft", "Blizzard", 88, 2014, "PC, iOS", 2, 10.00],
["Mass Effect 3: Citadel", "EA", 84, 2013, "PS3, Xbox 360", 7, 22.55]]
end
Now that we have an interpreter array (we can call on this to easily find indeces for values throughout the @games array), we can start defining those elements we'd expect to find in an inventory manager: things like the ability to tell us what games we have, how many, what the price is. Preferably we'd also like them to be able to add and remove games from the shelves, but for brevity's sake we'll just keep it simple for now. Let's add a lookup tool, so we can ask our inventory manager what items we have with a certain value:
def search_inventory(lookup)
lookup = @games_table.index(lookup)
return @games.collect{ |x| x[lookup] }
end
Basically, all we're doing here is creating a variable lookup and referencing @games_table to get an index. From here we can lookup from our array any title, critic score, price, etc
Now, you may have noticed something a little odd about our variables - specifically that we're starting certain variables with an ampersand ("@") sign. Any variable beginning with an amerpsand becomes an instance variable in the defintion of a class. What that means is that the variable will persist through the instance of that class - very important in the cases where we're dealing with data sets (arrays, hashes, etc) or previously-manipulated data.
Now, let's ask our inventory manager what our total inventory of games is:
def display_inv
@games.each{ |n| puts "price: #{n[0]}, publisher: #{n[1]}, metacritic: #{n[2]},
release year: #{n[3]}, available_on: #{n[4]}, inventory: #{n[5]}, price: #{n[6]}:"
puts }
end
Another simple array iteration that lists each item within the multidimensional array. Granted we're using some string interpolation to name our data. This could be done more cleanly with a series of symbols... but as we haven't really covered that yet in DBC, I'm not going to attempt it here.
Finally, let's build a method within the class to add a game (and all its pertinent information) to the games dataset
def add_new_game(title, publisher, metacritic, release_year, available_on, inventory, price)
@games << [title, publisher, metacritic, release_year, available_on, inventory, price]
puts "Please verify new game has been added to database."
display_inv
end
end
You'll notice that along with the "end" on our definition we've also got a non-indented "end" - that's used to close our class. (Trust me it would look better if this code was all nice and in-line).
Now that we've done some initial definintion of our inventory manager object-robot-buddy, lets start actually demanding things of him:
game1 = GameInventory.new
game1.add_new_game('Dishonored', 'Bethesda', 91, 2012, "PC, PS3, Xbox 360", 1, 35.00)
game1.search_inventory('title')
game1.display_inv
So what we've done here in the first line is actually create an instanceof the inventory manager. He will have his own inventory array to watch over, and whatever we tell him to do will exist within that instance of the Class "GameInventory". We could make half a dozen inventory managers, if we wanted to... perhaps useful if we had different stores all logging into the same website to manage their own inventory. Of course, if this was the case we'd want to save their inventory data outsideof the instance when they logged out and closed up shop, then call it up again when the store opened the next day.
To be honest, I'm still processing the concept of Objects. Granted we've used them to create games and decipher codes, and for games I can understand why you'd want a single instance - you don't want to start over a new game every time you take a turn - you want the game to persist. With code-crackers, its a little different story. You could, technically write a single method that cracks a code, as long as you have some algorithms defined in othermethods.
The case, to me, for Classes-as-Objects, seems to be a case for scalability. That is, as we begin as students to grap the concept of Object Oriented Programming, we will also start to recognize that our (current) heavy reliance on, say, conditional logic, will become very problematic as our challenges get more difficult and our solutions more complex. I've already noticed that I can create Class-methods that reduce hugely long case logic with simple one-or-two line processing logic. Even during refactoring I've noticed that it's far easier to identify where something breaks wen you don't have a 30 line conditional method.
Just as we could continue to "train" our little inventory manager buddy above with new methods - how to control inventory numbers, how to deal with sales, how to distribute games sold online, etc - I'm starting to understand the value of building Classes. They're effectively tools and machinery to get a job done. Also, I imagine, in a team environment, embracing OOP and building solid Class objects would prove immensely simpler and less confusing to debug or add features to.
