Framework for Rather Awesome Games
Introduction
FRAG is a cross-platform 2D (eventually 3D) game creation framework for the Nim programming language. It is still very early in its development lifecycle so if you decide to use it, please understand it will be rough around the edges. Please also note that this documentation may be incomplete and or may rapidly change.

Standards information
- Scalable Vector Graphics: Metadata, Section 21.4.1
Remarks
Note In addition to the attributes, properties, events, methods, and styles listed above, SVG elements also inherit core HTML attributes, properties, events, methods, and styles.
You should specify metadata, which you can include with SVG content, within metadata elements. The contents of a metadata element should be children elements from other XML namespaces that are expressed in a manner that conforms with the Namespaces in XML Recommendation.
You should provide a metadata child element to the outermost svg element within a stand-alone SVG document. The metadata child element to an svg element identifies document-level metadata.
Note We recommend that you add at most one metadata element as a child of any particular element, and that this element appear before any other child elements (except possibly desc or title elements) or character data content.
Examples
The following code example demonstrates how you can include metadata in an SVG document. This example uses the Dublin Core version 1.1 schema. (You can also use other XML-compatible metadata languages, including ones that are not based on RDF.)
<?xml version="1.0" standalone="yes"?> <svg width="4in" height="3in" version="1.1" xmlns = 'http://www.w3.org/2000/svg'> <desc xmlns:myfoo="http://example.org/myfoo"> <myfoo:title>This is a financial report</myfoo:title> <myfoo:descr>The global description uses markup from the <myfoo:emph>myfoo</myfoo:emph> namespace.</myfoo:descr> <myfoo:scene><myfoo:what>widget $growth</myfoo:what> <myfoo:contains>$three $graph-bar</myfoo:contains> <myfoo:when>1998 $through 2000</myfoo:when> </myfoo:scene> </desc> <metadata> <rdf:RDF xmlns:rdf = "http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:rdfs = "http://www.w3.org/2000/01/rdf-schema#" xmlns:dc = "http://purl.org/dc/elements/1.1/" > <rdf:Description about="http://example.org/myfoo" dc:title="MyFoo Financial Report" dc:description="$three $bar $thousands $dollars $from 1998 $through 2000" dc:publisher="Example Organization" dc:date="2000-04-11" dc:format="image/svg+xml" dc:language="en" > <dc:creator> <rdf:Bag> <rdf:li>Irving Bird</rdf:li> <rdf:li>Mary Lambert</rdf:li> </rdf:Bag> </dc:creator> </rdf:Description> </rdf:RDF> </metadata> </svg>

London theater hosting 'Death of a Salesman' evacuated when portion of ceiling collapses
by Louis CasianoSeveral people suffered minor injuries when the ceiling in a London theater collapsed during a Wednesday performance of Arthur Miller’s “Death of a Salesman."
Police responded to the Piccadilly Theater in the city's West End area around 8 p.m. after part of the ceiling crashed down. More than 1,000 people evacuated the venue, the BBC reported.
BBC journalist Iain Haddow was at the play and said the collapse happened 20 minutes into the show. He said water had been dripping, "which turned progressively into a stream."
Actor Wendell Pierce -- known for his work in HBO's "The Wire," the 2014 film "Selma" and numerous other TV roles -- plays the main character of Willy Loman. He apologized to theatergoers outside.

“I did not mean for it to go like this,” he said in a video posted to Twitter. "I would like to thank you all, for one, safely evacuating. We apologize and we're glad that no one's hurt."


Zale fell to his knees(metaphorically) he was foolish to think that persecuting his own people would solve the year long genocide,he wept over what a fool he was "There there"said cody hugging his father"your son is here for you wow i never thought a child would comfort a parent"
To make along story short zale repented for his crime,the merfolk and sea monsters stopped fighting and became friends and kito's healing potion was able to heal up alesha and she was back in ship shape
"My people" said zale to his kingdom later that day "first of all i would like to apologize for what i have done it was foolish to think making you all suffer would end the long war between merfolk and sea monsters. And for you sea monsters the time has come to forget about the past and move on in life,I know that back then we didn't get along,but now we have a chance to make things right our home is now your home. The time has come to put the past behind you,it's time to move on in life you are all welcome in this land, but most of all i would like to thank my son who i thought i lost but have found,prince cody, The man who ended this genocide between merfolks and sea monsters and helped me become whole again " the crowd cheered as cody came up to the balcony,"Now that you know where you belong"said king zale "will you stay with us and live amongst us?"
If cody decides to go back to the surface seeing he made a whole life there


AhoCorasickTrie: Fast Searching for Multiple Keywords in Multiple Texts
Aho-Corasick is an optimal algorithm for finding many
keywords in a text. It can locate all matches in a text in O(N+M) time; i.e.,
the time needed scales linearly with the number of keywords (N) and the size of
the text (M). Compare this to the naive approach which takes O(N*M) time to loop
through each pattern and scan for it in the text. This implementation builds the
trie (the generic name of the data structure) and runs the search in a single
function call. If you want to search multiple texts with the same trie, the
function will take a list or vector of texts and return a list of matches to
each text. By default, all 128 ASCII characters are allowed in both the keywords
and the text. A more efficient trie is possible if the alphabet size can be
reduced. For example, DNA sequences use at most 19 distinct characters and
usually only 4; protein sequences use at most 26 distinct characters and usually
only 20. UTF-8 (Unicode) matching is not currently supported.

For many Bitcoin investors a key benchmark of how low the Bitcoin market price can go is the cost of production during the mining process…
Break even (BE) back in 2014/15 was support, we were at bottom of BE this year with sporadic upward movements.
around 6k
New current and upcoming BE seems to be 7300
on avarage we are likely to end up around 36k mean BTC price end of 2019 wit rising BE
upper standard deviation of 3.2 is 42k, lower spectrum of 1.8 is around ~24k(edited)
I believe it will keep going sideways for sometime, not all indicators are reset yet
maybe a rally up to 11k and then down again.
ComputerGenie 👴👴👴26-Sep-18 11:52 AM
BE for miners on 1 brand specific piece of equipment as "base" price is among the silliest of ideas I've ever heard
Cryptoon26-Sep-18 11:53 AM
Some miners have lower electric cost than others as well, so each miner's BE price is situation specific
ComputerGenie 👴👴👴26-Sep-18 11:54 AM
secondary to that 1 piece of equipment being arbitrary
By that logic, RAM shortage should have sent ZEC price to the moon in March
bpkdasbaum26-Sep-18 11:56 AM
Yeah, it's not perfect, but there is BE pint for everybody, even if it's lower.
I imagine it can go as low as 5k, was also last resistance. in 2015 we went down to last resistence + the BE price. This created the support floor and went up from there to 20k
ComputerGenie 👴👴👴26-Sep-18 11:57 AM
otherwise they are forced to shut off their machines and stop mining, killing the supply.
There's so many holes in that idea that I'm going to have to take my bath and reflect on which I should address 1st

less hash does not ever equal less supply in any meaningful way longer than x blocks
Even if the hashrate dropped to 10% of what it is, the diff would adjust and life would go on

It's just divided over less miners when some shut down because it's not profitable for them to mine anymore
Give or take the same*
ComputerGenie 👴👴👴26-Sep-18 12:01 PM
the number of blocks mined every day is always the same
Well, for BTC, that's not entirely true, because of the length of diff change

jl777c26-Sep-18 12:05 PM
they are the "worlds best software devs" there is absolutely zero chance of any bugs in segwit, even it if is the most convoluted, complex and massive change ever made to bitcoin
they are just that good. nothing escapes them
bugs evaporate in front of them

please ignore that for 2 years until a BCH dev found the bug that BTC could have been doublespent at anytime by any miner
actually the vins could have been used multiple times to create new coins, so technically not a double spend
blackjok3r26-Sep-18 12:11 PM
did someone do that
?
bpkdasbaum26-Sep-18 12:13 PM
@ComputerGenie 👴👴👴 killing was the wrong word to use. But as a miner if I am below BE thinking from a business perspective I would shut off mining to minimize running costs, but also sell as little coins as possible, simply survice until BTC prices are up again to sell at better profit margins. maybe not right out killing the supply, but reducing it. sell coins only if needed. Also the shift in hash should allow more "non business" miners to get a bugger shared of generated coins. I am assuming here, but as a private miner with a home setup you are more likely to hodl. thanks for correcting and your insights.(edited)
jl777c26-Sep-18 12:13 PM
nobody did, but could have happened any block prior to recent fix
other than the 2016 block diff adjusting period, the total supply will be the same
unless there was a sudden 90% drop in hashrate (unlikely) any gradual drop will be adjusted for and total supply would be the same
now, whether the "new" miners are more or less likely to hodl than sell... this is not knowable, if anything the percentage sold could go up, increasing the supply.
I think the only think we can conclude from a massive drop in price is a lot of hashrate will be forced to be turned off. What else can be guessed would only be a guess
hashrate and price are intertwined, with causality of one unclearly linked to the other

As a professional miner, that says to me that you have 0 actual belief in the longevity of the currency itself and I'll address that in a bit, but first I must do a bit of "window shopping" to address how off the math is in the selection of a vanilla S9 in the 1st place (and then I'll come back to the insane idea that Core doesn't already have a "emergency hardfork" [that adjusts the diff formula] prepared for lack of hash after bcash created essentially the same issue).

Genie says btc is a shitcoin and isn’t worth 4k.
You're 1/2 right, because I said it should max at ~$4200 (not under $4k)

'An Officer and a Gentleman'
A retrospective movie review by Walter Frith
'An Officer and a Gentleman' did an extraordinary thing when it was first released in 1982. Not only did it showcase the best performance of Richard Gere's career, but it found the perfect balance necessary in appealing to both men and women. Many of my friends saw the movie on their first dates and it struck an emotional chord with many of them. It also made personality the main focus of its moral overtones and while it did appear at times to play out like a soap opera, no one can accuse it of being a false statement on life.
Set in Seattle, Washington, the opening scene is rather unattractive as it shows Gere in a hotel room pulling up the blind and the camera shows two naked people embraced together in bed. It turns out to be Gere's father (Robert Loggia) and a prostitute. Gere informs his father (an alcoholic and womanizer) that he has joined the officer's candidate school of the local Navy branch. His father laughs and Gere walks out on him.
The film's opening credits are displayed as Gere rides his motorcycle to the military academy and he along with a host of others are grilled in an opening monologue by their drill sergeant (Louis Gossett, Jr. who won the Best Supporting Actor Oscar). He immediately takes a disliking to Gere and his ways.
Gere turns out to be a hustler for profit. Selling things like boots, belt buckles and other accessories to the men in his bunkhouse. The film also shows his developing friendship with a fellow officer candidate (David Keith) and Gere has a romantic fling with a local factory girl (Debra Winger) who turns him into what the title suggests, 'An Officer and a Gentleman'. It was an Oscar nominated role for Winger which she excelled at.
What is most enjoyable about the film are the one-on-one scenes which involve Gere and Gossett. Gossett certainly is a major factor in molding and shaping Gere into becoming a better person but more importantly he is the ideal authority figure in Gere's life and he's like one of those teachers we hated at the time we were learning but later we realize that their methods were for are own good and we come to admire them.
Another bonus to the film is seeing how negative moral choices can play a permanent part in life and while the film doesn't try and force the issue of morals, it simply paints them as unavoidable parts of out existence.

I’m working on a web service for a document management system, where clients grab documents from the web service, modify them and submit the updates. Since multiple clients can all grab the same document at the same time, we needed to implement an optimistic locking scheme. In this scheme, each document has a version number, and when the client submits an update to the service, the service checks to see whether the submitted version number baseline is still the most recent one in the database. If so, we increment the version number and the update proceeds. Otherwise, we throw an exception indicating a conflict.
From a technology perspective we’re using Spring Data REST, Spring Data JPA, JPA and Hibernate to implement the web service. So I originally tried to use JPA’s @Version annotation. But for reasons I describe here it doesn’t work. Marten Deinum notes further that this isn’t really a problem with Spring Data REST per se; it affects e.g. form submissions too. At Marten’s suggestion, I created an enhancement request, but since I needed something now, I set out to implement optimisitic locking for Spring Data REST without @Version
.
The trick is to listen for events that are fired before the update occurs. Spring Data REST fires such events, but so does JPA, and I decided to use JPA’s events instead to ensure that the version number get/test/increment happens as part of a single atomic transaction. (My guess is that the Spring Data REST BeforeSaveEvent fires before entering the transaction.)
Here’s the code. First, here’s an interface for versioned entities.
package myapp.entity;
public interface VersionedEntity {
Long getVersion();
void setVersion(Long version);
}
Next we have an abstract base class for versioned entities. I could have done a mixin-style implementation here (using, e.g., AspectJ inter-type declarations), but I decided to keep it simple for now.
package myapp.entity;
import javax.persistence.Column;
import javax.persistence.EntityListeners;
import javax.persistence.MappedSuperclass;
import myapp.repo.listener.OptimisticLockListener;
@MappedSuperclass
@EntityListeners(OptimisticLockListener.class)
public abstract class AbstractVersionedEntity implements VersionedEntity {
@Column(name = "VERSION")
private Long version;
@Override
public Long getVersion() { return version; }
@Override
public void setVersion(Long version) { this.version = version; }
}
Notice the @EntityListeners
annotation. This tells JPA which class will listen for JPA lifecycle events. Here’s the OptimisticLockListener
.
package myapp.repo.listener;
import javax.persistence.PreUpdate;
import org.springframework.stereotype.Component;
import myapp.entity.VersionedEntity;
import myapp.util.ApplicationContextProvider;
public class OptimisticLockListener {
@PreUpdate
public void preUpdate(Object entity) {
if (entity instanceof VersionedEntity) {
getChecker().check((VersionedEntity) entity);
}
}
private OptimisticLockChecker getChecker() {
return ApplicationContextProvider
.getApplicationContext()
.getBean(OptimisticLockChecker.class);
}
}
In the listing above we grab an OptimisticLockChecker
and then run the check. I’ve implemented that as a separate class because I’m going to need the application’s JdbcTemplate
to do the version check, and I need a managed bean to inject the JdbcTemplate
. Unfortunately, JPA 2.0 doesn’t treat entity listeners as managed beans (apparently that will change in JPA 2.1). That’s why there’s a separate OptimisticLockChecker
class.
Venkatt Guhesan offers ApplicationContextProvider
as a clever way to get the app’s context from an unmanaged instance. Here’s the technique.
package myapp.util;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
public class ApplicationContextProvider implements ApplicationContextAware {
private static ApplicationContext applicationContext;
public static ApplicationContext getApplicationContext() { return applicationContext; }
@Override
public void setApplicationContext(ApplicationContext appContext) throws BeansException {
applicationContext = appContext;
}
}
Finally, let’s look at the OptimisticLockChecker
itself.
package myapp.repo.listener;
import java.lang.reflect.Field;
import javax.persistence.Column;
import javax.persistence.OptimisticLockException;
import javax.persistence.PersistenceContext;
import javax.persistence.Table;
import org.springframework.beans.BeanUtils;
import org.springframework.core.annotation.AnnotationUtils;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;
import org.springframework.util.ReflectionUtils;
import myapp.entity.VersionedEntity;
@Component
public class OptimisticLockChecker {
@Inject private JdbcTemplate jdbcTemplate;
public void check(VersionedEntity entity) {
Long submittedVersion = entity.getVersion();
if (submittedVersion == null) {
throw new RuntimeException("Submitted entity must have a version");
}
Class<?> entityClass = entity.getClass();
Annotation tableAnn = AnnotationUtils.findAnnotation(entityClass, Table.class);
String tableName = (String) AnnotationUtils.getValue(tableAnn, "name");
Field idField = ReflectionUtils.findField(entityClass, "id");
Annotation idColAnn = idField.getAnnotation(Column.class);
String idColName = (String) AnnotationUtils.getValue(idColAnn, "name");
String sql = "select version from " + tableName
+ " where " + idColName + "=" + entity.getId();
Long latestVersion = jdbcTemplate.queryForObject(sql, Long.class);
if (submittedVersion != latestVersion) {
throw new OptimisticLockException(
"Stale entity: submitted version " + submittedVersion
+ ", but latest version is " + latestVersion);
}
entity.setVersion(entity.getVersion() + 1);
}
}
Despite appearances, the code is a little tricky because we’re trying to compare an entity version in the persistence context with an entity version in the database, and by design JPA hides the database from the developer. There are different ways to achieve this, but the most straightforward and reliable is probably to use JdbcTemplate
to get the latest version in the database. We use Spring’s AnnotationUtils
and ReflectionUtils
to grab the table name and ID column name from the @Table
and @Column
annotations. (Note that the code above is for a @Column
annotation defined on the field itself; if you’ve defined @Column
on the getter, then you can use AnnotationUtils
to get at that.)
After that, we compare and either throw an exception or else increment the version number.
Perhaps the Spring Data REST guys will provide more direct support for @Version
(or some suitable alternative) at some future point. Until then, I hope the approach above proves useful.


Robot Simulator
Description
The goal of this project was to develop a python3 program between the group that simulates a basic robot like game. I implemented a UI which allows different parameters to be changed for the various simulations.
Progress
| Week | Progress |
|---|---|
| 1 | The group worked our an design for the project. I looked at the various ways of implementing my UI, initially looking at doing it via a web server written using Flask. |
| 2 | Did further research and worked on the interface more. |
| 3 | Changed the UI to tkinter to make the program easier to integrate in the end. |
| 4 | Implemented a function to find the distance between the starting point and also code to tell if two robots on the map are close. I wrote unit tests to test the various parts of the program. Attempted to integrate all the groups code into a single program. |

psychopy.voicekey
- Real-time sound processing¶(Available as of version 1.83.00)
Hardware voice-keys are used to detect and signal acoustic properties in real time, e.g., the onset of a spoken word in word-naming studies. PsychoPy provides two virtual voice-keys, one for detecting vocal onsets and one for vocal offsets.
All PsychoPy voice-keys can take their input from a file or from a microphone. Event detection is typically quite similar is both cases.
The base class is very general, and is best thought of as providing a toolkit for developing a wide range of custom voice-keys. It would be possible to develop a set of voice-keys, each optimized for detecting different initial phonemes. Band-pass filtered data and zero-crossing counts are computed in real-time every 2ms.
psychopy.voicekey.
OnsetVoiceKey
(sec=0, file_out='', file_in='', **config)¶Class for speech onset detection.
Uses bandpass-filtered signal (100-3000Hz). When the voice key trips, the best voice-onset RT estimate is saved as self.event_onset, in sec.
| Parameters: |
config: kwargs dict of parameters for configuration. defaults are:
|
|---|
detect
()¶Trip if recent audio power is greater than the baseline.
join
(sec=None)¶Sleep for sec or until end-of-input, and then call stop().
save
(ftype='', dtype='int16')¶Save new data to file, return the size of the saved file (or None).
The file format is inferred from the filename extension, e.g., flac. This will be overridden by the ftype if one is provided; defaults to wav if nothing else seems reasonable. The optional dtype (e.g., int16) can be any of the sample types supported by pyo.
slippage
¶Diagnostic: Ratio of the actual (elapsed) time to the ideal time.
Ideal ratio = 1 = sample-perfect acquisition of msPerChunk, without any gaps between or within chunks. 1. / slippage is the proportion of samples contributing to chunk stats.
start
(silent=False)¶Start reading and processing audio data from a file or microphone.
started
¶Boolean property, whether .start() has been called.
stop
()¶Stop a voice-key in progress.
Ends and saves the recording if using microphone input.
wait_for_event
(plus=0)¶Start, join, and wait until the voice-key trips, or it times out.
Optionally wait for some extra time, plus, before calling stop().
psychopy.voicekey.
OffsetVoiceKey
(sec=10, file_out='', file_in='', delay=0.3, **kwargs)¶Class to detect the offset of a single-word utterance.
Record and ends the recording after speech offset. When the voice key trips, the best voice-offset RT estimate is saved as self.event_offset, in seconds.
| Parameters: |
delay: extra time to record after speech offset, default 0.3s. |
|---|
The same methods are available as for class OnsetVoiceKey.
Several utility functions are available for real-time sound analysis.
psychopy.voicekey.
smooth
(data, win=16, tile=True)¶Running smoothed average, via convolution over win window-size.
tile with the mean at start and end by default; otherwise replace with 0.
psychopy.voicekey.
bandpass
(data, low=80, high=1200, rate=44100, order=6)¶Return bandpass filtered data.
psychopy.voicekey.
rms
(data)¶Basic audio-power measure: root-mean-square of data.
Identical to std when the mean is zero; faster to compute just rms.
psychopy.voicekey.
std
(data)¶Like rms, but also subtracts the mean (= slower).
psychopy.voicekey.
zero_crossings
(data)¶Return a vector of length n-1 of zero-crossings within vector data.
1 if the adjacent values switched sign, or 0 if they stayed the same sign.
psychopy.voicekey.
tone
(freq=440, sec=2, rate=44100, vol=0.99)¶Return a np.array suitable for use as a tone (pure sine wave).
psychopy.voicekey.
apodize
(data, ms=5, rate=44100)¶Apply a Hamming window (5ms) to reduce a sound’s ‘click’ onset / offset.
Several helper functions are available for converting and saving sound data from several data formats (numpy arrays, pyo tables) and file formats. All file formats that pyo supports are available, including wav, flac for lossless compression. mp3 format is not supported (but you can convert to .wav using another utility).
psychopy.voicekey.
samples_from_table
(table, start=0, stop=-1, rate=44100)¶Return samples as a np.array read from a pyo table.
A (start, stop) selection in seconds may require a non-default rate.
psychopy.voicekey.
table_from_samples
(samples, start=0, stop=-1, rate=44100)¶Return a pyo DataTable constructed from samples.
A (start, stop) selection in seconds may require a non-default rate.
psychopy.voicekey.
table_from_file
(file_in, start=0, stop=-1)¶Read data from files, any pyo format, returns (rate, pyo SndTable)
psychopy.voicekey.
samples_from_file
(file_in, start=0, stop=-1)¶Read data from files, returns tuple (rate, np.array(.float64))
psychopy.voicekey.
samples_to_file
(samples, rate, file_out, fmt='', dtype='int16')¶Write data to file, using requested format or infer from file .ext.
Only integer rate values are supported.
See http://ajaxsoundstudio.com/pyodoc/api/functions/sndfile.html
psychopy.voicekey.
table_to_file
(table, file_out, fmt='', dtype='int16')¶Write data to file, using requested format or infer from file .ext.

Kanye West - I was so excited on New Years Day to read that Kanye had released a new song. This excitement was quickly shattered after I hit play. It was the first time I’ve been truly disappointed in something that he has done. A couple weeks later he released another track. An even bigger disappointment.
Panda Bear - Panda Bear vs. Grim Reaper - This was the first record I got behind this year. I really haven’t spent too much time with him previously but am looking forward to digging deeper.
Viet Cong - Viet Cong - I had high hopes for this one. It didn’t disappoint. Has everything I’m looking for in a great Post-Rock album.
Cymbals Eat Guitars - Lose - This one of last years finer releases and it’s still been getting a lot of plays recently. It’s one of those Rock records that seems simple on the surface but the more you listen the more it opens itself up.
Lupe Fiasco - Tetsuo & Youth - This is a record that has yet to grab me yet I keep coming back to it every once in a while because maybe I’m missing something. Lupe has the potential to be a great rapper but it seems, especially lately, he’s been missing the mark.
Twin Shadow - There are 3 songs that you can listen to now from his up coming record. To The Top, Turn Me Up & Old Love / New Love. All three are fantastic. One of my most anticipated releases of the year.
Marty Robbins - Gunfighter Ballads & Trail Songs - This is an album I stumbled upon through a random Instagram profile. A classic from ’59 that I’d never heard. After hearing 3 songs I was blown away and ordered it on eBay. Great songs and great lyrics.
Sigur Ros & Fever Ray - There is something about the winter that alway brings me to these artists.
Kendrick Lamar - YES YES YES
P.S.  I didn’t watch them.

Pathfinder is not capable of following a path backwards. This leads to some problems.
Let's say that you want the robot to back up during a motion profile. Due to pathfinder's "feature", this is impossible.
So here is how we did it
In order to follow a path backwards, it should be drawn as normal in pathweaver, then the invert_path
flag should be set in PathingHelper
.
This will do the following to the path:
When the path has been finished, or the stop()
function has been called, all motors and encoders will be set back to normal settings.

Planets
A planet can be owned by one of the 4 teams. In rare cases, a failed attempt to capture a planet may result in that planet having 0 armies and being “independent”. Independent planets appear gray. A planet that has not been visited by your team since the start of the game, or since the last time it was captured, will also appear gray.
A planet with extra repair facilities will show a wrench icon in the center. A planet with extra fuel will show a fuel can on the right side. Orbiting a friendly planet with these facilities will result in faster repair or refueling.
A planet may not have any special facilities:
You can use the l (lowercase L) command to “lock on” to a planet and, when you get there, orbit it. A planet with more than 4 armies will also show the army icon on its left side. When you orbit a friendly or enemy planet, you can bomb it (b), beam up armies (z) or beam down armies (x). Bombing is only effective when there are more than 4 enemy armies. The last few enemy armies have to be destroyed by beaming down armies. Bombing, followed by 5 armies, is generally sufficient to capture any enemy planet.
Enemy planets damage your ship if you are close to it.

Cork company confirm it owns lorry in which 15 migrants discovered in England
A Cork company has confirmed that it owns the lorry in which 15 people were discovered in Wiltshire, England.
Sean Delany and Sons, a Glanmire-based company, confirmed to the Irish Examiner that the lorry is theirs.
An Irish man in his 50s has been arrested on suspicion of assisting the 15 people, believed to be men aged 16 – 30, with illegal entry into the country.
The lorry was stopped by police near Chippenham after reports of “suspicious activity” from a member of the public shortly before 8.30pm on Wednesday.
The fifteen people who were found in the rear of the lorry, have been arrested on suspicion of immigration offences.
One man was taken to hospital as a precaution but was later released into custody.
The other 14 people were deemed medically fit and were taken straight into custody on suspicion of immigration offences.
Wiltshire Police said the force was "not clear" about the nationalities of the 15 at this stage.
Superintendent Steve Cox thanked the "vigilant member of the public who initially reported this incident" and said that it was "thanks to them that this incident was resolved swiftly and safely with no serious casualties."
It comes after eight people were arrested earlier this week by Vietnamese police in connection with the 39 migrants found dead in a lorry in Essex.
They were held on Sunday on suspicion of organising people smuggling overseas.
The 31 men and eight women who were discovered in the back of the refrigerated truck in Grays in October are thought to have been Vietnamese.
So far two people have been charged.
Essex Police have started extradition proceedings to bring 22-year-old Eamonn Harrison from Ireland to the UK.
Harrison, of Newry in Co Down, Northern Ireland, appeared at Dublin High Court last Friday charged with 39 counts of manslaughter, along with human trafficking and immigration offences, and was remanded in custody.
The driver of the lorry, Mo Robinson, 25, appeared at Chelmsford Magistrates' Court charged with 39 counts of manslaughter, conspiracy to traffic people, conspiracy to assist unlawful immigration and money laundering.
Detectives have also urged Ronan Hughes, 40, and his brother Christopher, 34, said to have links with the road haulage and shipping industries, to hand themselves in.
The pair, from Armagh in Northern Ireland, are wanted on suspicion of manslaughter and human trafficking.

Emilee Chinn | FOR THE POST
The first floor is too blocked off from light or nature, and its fluorescent lights are a little too bright to be focused. The second and fourth floors are the entrances and have group work sections, so it’s always abuzz with disgruntled group workers pushing one another to do more. The fourth floor also has those highly coveted “egg chairs,” but they’re positioned just correctly so that it makes reading or writing in them simply awkward and uncomfortable. The sixth and seventh floors don’t have enough adequate workspace for someone who isn’t specifically looking through their collections, and although their views are beautiful, a window seat is few and far between.
The fifth floor, however, puts the rest of the floors to shame. On immediate entry, there is a spacious workspace with tall windows that reveal a view of Park Place. When sitting at the tables by the windows, it’s easy to fall into a trance watching snow fall atop Baker Center or students scurry to their classes. It gives students a chance to look out the window and forget about their worries, even if just for a second.
But its views are hardly what makes the fifth floor so special. On the other side of the study space, there are archives and special collections with a room built specifically for installations about Ohio University’s history. There is also a meditation room for folks who may just need a quiet break to look within themselves in the middle of their busy day.
The atmosphere of the fifth floor is perfect for studying. Although it is a designated quiet study space, it is not so quiet that students feel awkward about eating a bag of pretzels or one of those premade, dining hall salads that are so hard (and loud) to open. It’s not frowned upon to have a quiet chat with a partner or friend, but the noise level isn’t distracting either. It always has a nice, low hum that makes any student feel welcomed on the floor.
The best bathrooms in the library are also conveniently located right in the middle of the fifth floor. Although, upon first glance, they may appear to be dingy, they’re the cleanest, most private restrooms one can find in Alden. And when students are studying hard with their coffees, that is an important feature for a library to have.
Most of all, the fifth floor has the best climate in all of Alden. Other floors tend to sway toward either too cold or too hot, but the fifth floor is located just centrally enough in the building to have the most comfortable studying environment.
Although the other floors have their perks, none can compare to the fifth floor. It may not have Macs or egg chairs, but its peaceful, comfortable atmosphere means that any student will feel welcome.

[ISO,declaration]:- initialization
+Goal
Declares that Goal is to be run when the file in which the declaration appears is loaded into a running system, or when a stand-alone program or runtime system that contains the file is started up.
Callable at any point during loading of a file. That is, it can be used as a directive, or as part of a goal called at load time. The initialization goal will be run as soon as the loading of the file is completed. That is at the end of the load, and notably after all other directives appearing in the file have been run.
save_program/[1,2]
saves initialization goals in the saved state,
so that they will run when the saved state is restored.
Goal is associated with the file loaded and a module. When a file, or module, is going to be reloaded, all goals earlier installed by that file or in that module, are removed. This is done before the actual load, thus allowing a new initialization Goal to be specified, without creating duplicates.

Abstract
In this part , we are going to talk about how to read an image from a file, options for reading the image in case of its type , and the ways of how can we show it on the screen.
Including the necessary dependencies
First of all ,we have to include the packages needed to get the opencv good to go.
The first one is actually the opencv
itself which is the cv2
demonstrated in the code, then the numpy
that is used to handle numpy array (we will discuss about it later).
Load our image
Now we have to open our desired image, we use the following image.
we can load our image using imread
function. it loads the image specified by the first argument ( in our case , picture.png
). The second argument specifies the format in what we want the image. This may be :
-
IMREAD_UNCHANGED : loads the image as is (including the alpha channel if present) , this is a integer value which is -1 in python and a negative number in C++
-
IMREAD_GRAYSCALE : loads the image as an intensity one. this is like converting the image to a gray version of it. integer value of this argument is 0
-
IMREAD_COLOR : loads the image in the BGR format (blue , green , red). Integer value of this argument is 1 in python, and a positive number in C++.
For testing purposes , we create three images in all of the discussed formats and try to show all of them in seperated windows.
Show The Images
Now that we have stored the images, we try to show them on the screen. We can either use the cv2
library itself or matplotlib
.
But if you run this code, you see that nothing appears on the screen, actually the window will open and then closes before you see it. we should make it to wait until a specific action (in our case , pressing a button) happens.
the waitKey
function will wait until a key is pressed and the destoryAllWindows
function will closes all windows that are opened by cv2.

AWS Account¶
Amazon Web Services (AWS) provides a wide variety of cloud-based products including analytics, application integration, AR and VR, cost management, blockchain, business applications, compute, customer engagement, database, developer tools, end user computing, game tech, IoT, machine learning, management and governance, media services, migration and transfer, mobile, networking and content delivery, robotics, satellite, security, identity and compliance, and storage. Here at cloudmesh, we develop services through providers to support your utilization of many of these products.
Here we are especially interested in using the following services:
Amazon Elastic Compute Cloud (EC2) Amazon EC2 is web service that enables users to perform elastic web-scalable computing while having complete control over instances. It is integrated with most AWS services such as Amazon S3, RDS, and VPC.
Amazon Simple Storage Service (S3) Amazon S3 an object storage service that offers a wide range of storage classes.
We provide a step-by-step guide on how to create an AWS account through the AWS Web page to utilize these services. For more information you can consult the AWS FAQ.
First, we go to the AWS website
and click on Create an AWS Account
.
This will direct you to the account creation page. Now we fill out your
information and click Continue
.
Next, you will need to fill out your contact information. You can choose
Professional
or Personal
as your account type. Here in this
tutorial, we selected Personal
. Read the AWS Customer Agreement, and
check the box if agreed. Click on Create Account and Continue
to
continue.
Fill out your payment information and proceed. Dependent on your level of security, you may want to explore using a prepaid credit card if you do not want to use your regular credit card.
If you just started using AWS, you will have a free account for a while as AWS will state:
We will not charge you unless your usage exceeds the AWS Free Tier Limits. - Amazon AWS
Please review the terms of the free tier carefully.
Next your need to confirm your identity. You can choose either
Text message (SMS)
or Voice call
to receive your verification code.
Here we choose Text message (SMS)
. Enter your phone number and the
security check code and click Send SMS
.
Enter the 4-digit verification code you received from your phone, and
click on Verify Code
.
If you entered the correct verification code, you will see this page.
Click on Continue
.
You will need to choose your support plan. We chose Amazon’s free tier
Basic Plan
.
Congratulations! You have successfully created an AWS account. Now you
can click on Sign In to the Console
to sign in.
Enter the email address you used for registration, and click on Next
.
Enter the password you used for registration, and click on Sign In
.
Now you’ve successfully signed in to the AWS Management Console.
You can click on Services
to explore AWS services through their
Web page.
You can also start managing your account and instances through our cloudmesh services. This is especially of interest if you use cloudmesh to manage your storage and computational needs while also being able to leverage other clouds.
[ ] To do verify this works and you have created a user.
Access Key¶
Now that you have an account it is necessary that you can authenticate to your cloud account from a program or a command line. The instructions for this can be found at
-https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html
However, it is far easier to use the convenient cloudmesh tools by just using the cloudmesh open command.
In case you have not yet added a user, you can visit the user creation page with
cms open account aws
Create and Download Access Key¶
After logging into your account, you will then see the following console:
Click on Add user
and begin the process for creating a new user. Type the
name cloudmesh
in the User name
and make sure you check the programmatic access
:
After clicking on the Next: Permissions
, you then have to add the user to a
group. If you do not have any group created, click on Create group
button
and you will be redirected to the corresponding page. You can call the group
cloudmesh
and then check the select the AmazonEC2FullAccess
for the
permission:
After creating the group, select it so that the new user will be assigned to that group:
In the next page you can create the tags for the new user. You can just
create a cloudmesh
key for the user as a tag:
The next page is the review page where you can review the information you entered:
After clicking on Create user
the user will be finally created and you will
be redirected to the following success page:
You can view the secret access key by clicking on the show
button:
Next, download the .csv
file by clicking on the Download .csv
button and
save it as ~/.cloudmesh/credentials.csv
:
Then you can click on the close
button and go back to the IAM Management
Console which now provide you a summary of the newly created user called
cloudmesh
and looks like this:
By clicking on the Create access key
, you can create another access key:
As is mentioned in the screen shot, this is the only time you can view or
download the secret access key. So go ahead and click on the Download .csv file
and save it as ~/.cloudmesh/accessKey.csv
:
Using the Access Key¶
To obtain the keys for an already existing account or the one that you just created you can use the command
$cms open account aws NAME
This command will open a browser window to the credential page of AWS. PLease replace the NAME with your username that you created when you added your user to the IAM.
IN case you do not yet have a credentials choose the Security credentials tab and then choose Create access key. To see the new access key, choose Show. Your credentials will look something like this:
Access key ID: AAABBCCHHH7EXAMPLE Secret access key: wJalrXUtnFhsjlashlkjh/bPxRfiCYEXAMPLEKEY
To download the key pair, choose Download .csv file. Store the keys in a secure location and do not by default store them in the Downloads folder. We recommend that you store is in ~/.cloudmesh, but before doing so make sure the permissions for ~/.cloudmesh are restricted,
Compute Service¶
Import Public key¶
Before we get started with AWS compute services, we need to be sure we import our public ssh key. We assume an ssh has already been set up under ~\.ssh\id_rsa.pub
. If this prerequisite has not yet been satisfied, please reference the installation section.
While logged into AWS’s console, navigate to the EC2 Management Console under Services > Compute > EC2
:
Next, on the left-hand panel, navigate to Network & Security > Key Pairs
and select Import key pair
. Once you’re at the Import Settings screen, browse to ~\.ssh
and select the id_rsa.pub
file. Name the imported file after the same username configured you have configured in the cloudmesh.yaml file.
Cloudmesh.yaml Configuration for AWS¶
Please reference the section on Configuration for more information on getting, setting, and editing values to the cloudmesh.yaml configuration file; along with referencing the compute cloud provider templates and default values.
Run the following code to set the AWS compute provider values specific to your configuration. Alternatively, you can manually set these values using a text editor to update the cloudmesh.yaml file under ~\.cloudmesh
.
cms config set cloudmesh.cloud.aws.cm.active=true
cms config set cloudmesh.cloud.aws.credentials.region=AWSMGMTCONSOLEREGIONVALUE
cms config set cloudmesh.cloud.aws.credentials.EC2_SECURITY_GROUP=SECGROUPVALUE
cms config set cloudmesh.cloud.aws.credentials.EC2_ACCESS_ID=ACCESSIDVALUE
cms config set cloudmesh.cloud.aws.credentials.EC2_SECRET_KEY=SECRETKEYVALUE
Notes:
Region can be found while logged into the AWS management console in the upper right-hand side.
EC2_ACCESS_ID and EC2_SECRET_KEY values can be found either during the initial setup in AWS, or by referencing the Access Key downloaded as a csv and moved to the
~\.cloudmesh
directory.TODO: Confirm if EC2_PRIVATE_KEY_FILE_PATH and EC2_PRIVATE_KEY_FILE_NAME cloudmesh.yaml AWS compute variables are being utilized, as these are not referenced in
Provider.py
. If this is not needed, remove from cloudmesh.yaml. If this is needed, update the AWS account section with the following steps:Create a new key pair and name the key pair
aws_cert
. Then download the key and move to the~\.cloudmesh
directory.
Once the values have been set:
run the following to get started and test AWS compute services:
cms set cloud=aws
cms init
cms key init
cms vm boot
This should have allowed you to initialize cms with the updated configurations and boot up a new vm in AWS based.
Check the status of the vm by executing the following:
cms vm list --refresh
Now test stopping the vm. Note that you may need to give it a minute or two before you refresh the vm list to validate Status=stopped.
cms vm stop VMINSTANCENAME
Now test terminating the vm. (Note the example provided if you are attempting run commands against multiple vm’s.)
cms vm delete VMINSTANCENAME

Proof of Concept at Home, Production Build at Studio
By Allen Chen
Conveniently enough, Allen has a 3-D printer from AnyCubic in his bedroom. This is not a surprise becauase Allen is a huge advocate for rapid prototyping and maker culture.
Although this printer doesn't have top-tier print quality, it still prints really solid builds if we judge on a proof-of-concept prototype standard.
The advantage of printing at home is that it has near-zero turnover time. During our peak times, we complete one iteration on a design every two days, and it stayed like that for two weeks. This allowed
us to have, within the first 2 months of development:
- 3 iter. of Backpack (deprecated)
- 3 iter. of Midplate (deprecated)
- 4 iter. of Motor Mount (deprecated)
- 6 iter. of Solar Gear Bearing
- 13 iter. of Solar Gear Driver
- 7 iter. of Solar Gear Ring
- 5 iter. of Universal Mount
And whenever we are in need of production-level builds, we go to makerspaces that have high-end 3-D printers to print our parts.
The Solar Gear System
By Allen Chen
Our team had a lot of interesting discussions on how we want to approach the sunlight control problem. What was obvious to us was that we need an acutation system, but how do we want to build it?
To figure that out, we first need to decide which way to go - sideways, around, or vertically? All of the three ways seemed viable to us as ways to control sunlight input for our system.
We decided to explore the vertical option, only to find that it was a dead end. We called it the "Toaster" approach, because when we lift a blind up to block the sunlight, the system looks like a toaster
with a toast inside poking its head out. The success of this approach depended on two key factors, which we found both too difficult to solve in a clean way:
- We need to store the blind inside the toaster, just like the car window needs to be stored in the door. That means the toaster needs to be at least as tall, if not taller, than
the blind.
- We need to maintain the stability of the blind once it's fully up without support from the sides.
We then turned to the "around" option, and decided to go all in with that. Not only is it going to be much more robust than the other two approaches, but it's also cool to look at. I mean, who doesn't like gears?
We will have a spur gear system, with the smaller driver gear being driven by our stepper motor. The bigger follower gear, which we call the Ring, will be held in place in terms of translation but free in terms of rotation.
It will hold up a blocker that only covers a portion of the entire circle. We hold the Ring in place by letting it sit comfortably on a base, which we call the Bearing.
Months later, as we started doing hardware/software integration, we also added numerous minor tweaks to make them comply to our system requirements. Namely:
- Completely fill one of the gap between two Ring's gear teeth so that we can use it as a calibration lock.
- Merged the Ring with the blocker to be one big component.
- Levelled the base that the ring sits on and made holes for sensor wires and water tubes to go through.
- and of course, you guessed it, etc.
