Mushrooms - P. cubensis
This experience took place among eight friends in the fall of 1999, two days into a backpacking trip in Utah's Coyote Gulch. For me it followed a long summer of living alone in an attractive though unfamiliar city, and I had been anticipating the reunion for months. It's among the top three trips I've ever had.
As the morning wore on, and the eight of us cooked breakfast and filtered our water for the day, it became apparent that a feeling of excitement was starting to build. We nervously skittered up and down the banks of the river and climbed on the canyon walls. At noon we unwrapped the package of mushrooms [PF home grown] and divided them into eight small piles. As we began make our way down the canyon, munching happily on the fungus, each of us carried a small backpack of snacks, water, and an extra shirt or two. I strapped my didjeridoo to my back with a length of vibrant rock climbing rope. We skipped and laughed, held hands and chattered like schoolchildren.
Within minutes the world began its transformation. The stream began to sparkle as it never had before. Several people were gathered in the river, watching intently as something floated by. I excitedly ran over to join, and discovered with no small amount of surprise that the object of interest was in fact a swimming tarantula. A bizarre sight indeed! It must have fallen off the canyon wall, we all decided. It was now floundering in the muddy water, it's legs ill suited for an aquatic environment. A rather unusual start to a rather unusual afternoon.
We continued downstream, marveling at the intense detail and stark beauty of the canyon floor. Spring water seeped from a thin dark sandstone layer in the walls, creating a strip of deep green gardens hanging high above us. Everything around seemed to sparkle with a clarity and intensity that I had never before imagined. I was in awe of the fractal complexity of the river. As we splashed through the water we left forever the history of our steps.  Even standing still we could only watch powerlessly as the vortices peeled from our ankles. A butterfly flaps it's wings in Japan and a week later it rains in Escalante.
We walked on gingerly, the towering canyon walls climbing higher and higher above us. How tall Zach? 300 feet? 400? 400 what? How are we supposed to tell? Where are we anyway? What does it matter? We are here right now. We are ourselves. We are going places.
The canyon floor narrowed and the water quickened, slicing its way through the mud into the sandstone riverbed itself. Suddenly we found ourselves as giants, kneeling over an infant canyon being born before our eyes. The cool river water cut smooth, soft, sensual curves through the red rock. Liquid and solid in complement. We plunged our hands into the water, feeling the shapes hidden beneath, becoming a part of the birth itself. It seemed like it would take an eternity for water to cut through those few feet of stone, and yet as that thought flowed through my mind I tilted my head back and was met with the towering canyon above. We were no longer giants. We were elves. We were mites. We were specks.
I stopped further down and sat with Jen and Emily. Dan was worrying. We tried to comfort him. So many things had changed since we began our walk. What more would change? Where would it end? Is anything certain? I didn't know what to say. What if he was right? How could I really assure him that things would ever be normal? I sat there beneath the rock overhang, dumbfounded. Emily was more helpful. We are ourselves, and will always be. It's the nature of consciousness. He felt better.
I remembered the didjeridoo strapped to my back and began to play. My lips buzzed. My head vibrated. The sound was overpowering, enveloping my entire existence in a matter of seconds. In the droning darkness I came upon a funnel and slid down into it, falling deeper and deeper until I could no longer see the rim behind me. I lost myself in the darkness, sliding into another funnel, and then another, and another, until I could not recall any other existence. The droning stopped. I opened my eyes. Instantly I was jerked back through a thousand funnels by the inelastic rope of reality. A world of color, long since forgotten, exploded before me. Wow. I returned the didjeridoo its place on my back.
Emily was still talking to Dan. Jen asked me if I thought the canyon was echoing. After several minutes of experiments and deliberation we concluded that there were in fact several different echoes present, some within the canyon, some within our heads. The didjeridoo agreed. Carl, Sean and Zach suddenly came running upstream, babbling wildly and bursting with excitement. 'Could you *please* come and talk about Mars with us?' It looked like Dan was doing well with Emily's help. I splashed downstream with them.
As we walked along the four of us chattered excitedly like third graders. I felt full of energy. I felt full of amazement. I felt reborn. My life seemed to stretch off beyond the infinite horizon. We could do anything. We could go anywhere. I thought of the human race and how much potential it contained. We've done things unimaginable. We've teleported quantum states. We've built telescopes that can see things billions of light years away. Neutrinos have *mass*. There are *planets* around other *stars*. If we could only stop wasting time bickering over petty, short-term matters we just might really do something. It's time to start thinking beyond the Earth. It's time for us to go places.
The canyon began to narrow again. We wandered through red sandstone gates and hopped around narrow slots in the canyon floor. The whole scene now seemed like a hybrid of Earth and Mars. The colors were overpowering. Red rock, green life, blue sky. Desert, river, infinite existence.
We suddenly found ourselves beneath a great stone arch. Coyote Bridge. An arc of red within a sky of blue. We had traveled 1.5 miles from our camp. How many lifetimes had passed since then? The sun was low in the sky, peering at us over the canyon rim. It was time to turn back. Say, has anyone seen Mark lately?
We wandered back under the bridge, slowly making our way upstream. Carl ran ahead to find Jen. Sean set off for a spot on the canyon wall. Zane and I continued onward, savoring the last bits of the fading afternoon light, bathing ourselves in the beauty of each passing moment, stepping slowly, softly, carefully. We stopped and stood together in silence, hearing nothing but the hypnotic drone of cicadas. The quintessence of afternoon. Pure afternoon extract. Afternoon infinity. Okay, enough of that.
I removed the didjeridoo from my back and began to play. Civilization ceased to exist. We were primal beings again, predator and prey in the same moment, recalling a time when our bodies were the only tools we had. Animal blood coursed through my veins. I felt alive. But I was evolving, relearning myself, the blood slowly shifting from animal to human. Love and happiness welled up inside me. I stopped playing and smiled at Zach.
Up ahead we met Emily and sat watching the river water flow through a network of smooth sandstone troughs. They were the color and texture of weathered redwood, complete with rings recording the passage of time. The chaotic nature of the stream was hypnotic, and we watched and listened with amazement as the river level rose and fell in the stone channels.
Over a period of perhaps twenty minutes we watched the flow level in a single trough gradually increase from nothing to a few centimeters deep and then slowly taper back to nothing. This took place several times as we sat there in the fading evening light. Periodic cycle? Random fluctuations? Ripples upon ripples upon ripples. A butterfly flaps its wings in Japanů
It was starting to get dark. Still no sign of Mark. Dan appeared, having made it as far as the natural bridge before turning around. The four of us silently made our way upstream, lost in the mesmerizing liquid drumbeat of our footsteps. We passed the infant canyon and hanging gardens, stopping at the edge of an enormous stone dome. I looked up and saw that the night had arrived. Clouds were beginning to drift over the canyon. The four of us stood together in the darkness, our arms resting on each other's shoulders, our heads touching together in the center. Lightning flashed silently off in the distance. Soft, wet wind blew down through the canyon. The river flowed smoothly between our feet. We drew together, hugging tightly. I pressed my face into someone's hair and squeezed the shoulders I was holding. Human darkness. Human warmth. I felt timeless, each moment drawing out into an eternity of love and happiness. I'll never forget that feeling as long as I live.
I'm not sure how long we stood there. perhaps thirty minutes, perhaps more. Eventually Sean wandered down the river and found us standing silently in the night. The rain began softly with warm, delicate drops. Lightning flashed overhead, and for an instant the canyon was as bright as day. Then darkness. Seconds later thunder roared through us like a freight train, overpowering in its intensity. It was definitely time to head home.
Blindly we resumed our walk up the river, arm in arm, stepping gingerly over rocks and mud. The rain became a shower, and then a downpour. Lightning flashed every few seconds, illuminating for split seconds the river and red canyon walls, but between flashes we could see nothing. The thunder ripped through the canyon and pressed into my gut with such overwhelming force that I was afraid I would fall to my knees. But we continued on, holding tightly to each other, stumbling through the muddy water. Zach howled with excitement, squeezing our arms together. An exhilarating, primal fear began to rise inside me. It welled up hot and boiling in my heart, forcing itself up my throat in a scream. I felt alive.
We staggered back to our camp beneath the dome. Amazingly enough it was dry despite the storm. We laughed at our luck and happily changed into dry clothes. The river, just a trickle earlier in the day, was now a muddy, roaring torrent in comparison. A waterfall of rain cascaded off the lip of the dome hundreds of feet above us, caught in motion every few seconds by the flare of a lightning bolt. Thunder roared through our camp nearly continuously. Wind whipped over the canyon walls, carrying enormous sheets of water.  Somehow, in the midst of this chaos we sat quietly together, contentedly munching on trail mix and warm risotto, enjoying the company of the best of friends.
We slept that night in a warm pile, hugging closely as the thunder receded into the distance. I put an arm around Zach, and felt Emily's head against me. Friendship. Warmth. Content. Satisfaction. Happiness. Love. I smiled. I slept.
Shortly after sunrise Mark wandered back into camp, tired, cold, wet and hungry, but fortunately for all of us, alive. He'd spent the entire night shivering beneath the insufficient shelter of a bush, getting in touch with his wild canyon-dweller instincts. We breathed a collective sigh of relief, and started to pack.

What is LNCediting?
LNCediting is a database to provide a comprehensive resource for the functional prediction of RNA editing in long non-coding RNAs (lncRNAs) across four species, including human, mouse, rhesus and fly. It contains editing sites in lncRNAs, structure change by editing and the binding sites of lncRNA:miRNA which may be impacted by editing sites. In total, we identified 195,907 RNA editing sites in four lncRNA transcripts and found thousands of editing sites which greatly impact the secondary structure of lncRNA and the binding of miRNA-lncRNA. Currently, users can:
- Browse or search the editing sites in lncRNAs;
- Browse or search the impacts of the editing sites on RNA secondary structure;
- Browse or search the editing sites impacting the interaction of miRNA:lncRNA (loss or gain);
- Browse or search miRNA expression data to prioritize functional editing sites;
- Predict the function of customized editing sites in lncRNAs

Pipeline to construct LNCediting
Editing sites in lncRNAs
Human lncRNA annotation (hg19) was downloaded from LNCat, which is a comprehensive annotation resources for human lncRNAs and has collected lncRNA transcripts from 13 resources, including three widely used lncRNA databases (GENCODE, NONCODE and LNCipedia) and 10 individual studies (CABILI, HANGAUER, HE, IYER, KELLEY, KRETZ, PARALKAR, TRIMARCHI, WHITE and YANG. Details please refer to “A comprehensive overview of lncRNA annotation resources”). Mouse lncRNA annotation was downloaded from NONCODE (mm10) and GENECODE (mm10), while the lncRNA annotations of rhesus and fly were downloaded from NONCODE.
The editing sites of human, mouse and fly were downloaded from RADAR, while the editing sites of the rhesus was obtained from the study of “RNA Editome in Rhesus Macaque Shaped by Purifying Selection”. There are 2576459, 8823, 31250 and 5025 editing sites of human (hg19), mouse (mm9), rhesus (mac2) and fly (dm3), respectively. By using the UCSC liftover tool, we transferred the coordinates of editing sites to mouse (mm10) rhesus (mac3) and fly (dm6), respectively. Then, the coordinates of the editing sites were mapped to that of lncRNA exons and we recorded the editing sites in lncRNAs.
| Human | Mouse | Rhesus | Fly | |
| The number of editing sites (transferred) | 2576459 (hg19) | 8822 (mm10) | 26861 (mac3) | 5025 (dm6) |
| The number of LncRNAs | 301896 | 59574 | 15450 | 68706 |
| Editing sites in lncRNA exons | 191991 | 1922 | 165 | 1829 |
Editing sites impact on lncRNA secondary structures
According to the lncRNA transcript annotation, we extracted lncRNA transcript sequences from human/mouse/rhesus/fly reference genome file as unedited-type transcripts. For each editing site, we changed the corresponding editing base from A->G as edited-type transcript. Then, RNAfold program was used to illustrate the secondary structure and calculate the minimal free energy (MFE, ΔG). Energy change of RNA structures (ΔΔG) was calculated by the MFE differences using ΔΔG = ΔGedited－ΔGunedited, where ΔGunedited and ΔGedited are the MFEs of the unedited-type transcript and edited-type transcript, respectively.
miRNA:lncRNA gain/loss of function
The miRNA mature sequences were downloaded from miRBase. The TargetScan and miRanda were used to predict the miRNA binding sites on unedited-type lncRNAs (UT) and edited-type lncRNAs (ET), which result in four groups of target datasets, which are TU (TargetScan predicted targets on UT sequence), MU (miRanda predicted targets on UT sequence), TE (TargetScan predicted targets on ET sequence), and ME (miRanda predicted targets on ET sequence). The miRNA–lncRNA interactions that exist in both TU and MU, but in neither TE nor ME, were defined as interaction losses (Loss= (TU and MU) - (TE or ME)). On the contrary, the miRNA–lncRNA interactions that exist in both TE and ME, but in neither TU nor MU, were defined as interaction gains (Gain= (TE and ME) - (TU or MU)).
miRNA expression
In human module, we provided miRNA expression data to help users to prioritize the results. The miRNA expression data of different cancers were downloaded from TCGA. We calculated the average expression of each miRNA in every tissue based on TCGA miRNA-seq level 3 normalized data.
Website usage
Homepage
We provide the information of four species, including human, rhesus, mouse and fly. Click the photo of homo sapiens, you will go to the human sub-website. Then you can browse the editing, lncRNA and miRNA sections. By clicking the photo of “LNCediting”, You will come back to the homepage.
Editing section
The editing section stored all the editing sites in lncRNAs as well as their detailed information. Data in this section include: (i) basic information of the editing sites; (ii) editing impacts on lncRNA secondary structure; (iii) editing impacts on miRNA–lncRNA interaction. We set two options to optimize the results. The first is the ‘Position’ option allowing users to query editing sites in a user-defined chromosome region. The second is the ‘Source’ option helping users to filter results by limiting the source of lncRNA.
miRNA section
The miRNA section enables users to select interested miRNAs by expression to obtain their targeting lncRNAs and possible gain/loss target of lncRNAs. In this section (human only), the miRNAs have been classified into four categories according to their expressions. They were high expressed miRNA group (RPM ≥ 1000), middle expressed miRNA group (10 ≤ = RPM < 1000), low expressed miRNA group (1 ≤ RPM < 10) and unexpressed miRNA group (RPM < 1). For each human miRNA, we also provide the expression levels in 28 cancer types in the ‘basic information of miRNA’ part.
Online tools
Online tools enable users to input lncRNA sequence and the position of the novel editing site, then the secondary structure of unediting-sequence and editing-sequence will be plotted and the miRNA binding sites will be displayed.

An example project by Atta.


28 Jan 2014 by Robert Metzger (@rmetzger_)
We recently merged a pull request that allows you to use any existing Hadoop InputFormat with Stratosphere. So you can now (in the 0.5-SNAPSHOT
and upwards versions) define a Hadoop-based data source:
HadoopDataSource source = new HadoopDataSource(new TextInputFormat(), new JobConf(), "Input Lines");
TextInputFormat.addInputPath(source.getJobConf(), new Path(dataInput));
We describe in the following article how to access data stored in MongoDB with Stratosphere. This allows users to join data from multiple sources (e.g. MonogDB and HDFS) or perform machine learning with the documents stored in MongoDB.
The approach here is to use the MongoInputFormat
that was developed for Apache Hadoop but now also runs with Stratosphere.
JobConf conf = new JobConf();
conf.set("mongo.input.uri","mongodb://localhost:27017/enron_mail.messages");
HadoopDataSource src = new HadoopDataSource(new MongoInputFormat(), conf, "Read from Mongodb", new WritableWrapperConverter());
Example Program
The example program reads data from the enron dataset that contains about 500k internal e-mails. The data is stored in MongoDB and the Stratosphere program counts the number of e-mails per day.
The complete code of this sample program is available on GitHub.
Prepare MongoDB and the Data
- Install MongoDB
- Download the enron dataset from their website.
- Unpack and load it
bash
bunzip2 enron_mongo.tar.bz2
tar xvf enron_mongo.tar
mongorestore dump/enron_mail/messages.bson
We used Robomongo to visually examine the dataset stored in MongoDB.
Build MongoInputFormat
MongoDB offers an InputFormat for Hadoop on their GitHub page. The code is not available in any Maven repository, so we have to build the jar file on our own.
- Check out the repository
git clone https://github.com/mongodb/mongo-hadoop.git
cd mongo-hadoop
- Set the appropriate Hadoop version in the
build.sbt
, we used1.1
.
hadoopRelease in ThisBuild := "1.1"
- Build the input format
./sbt package
The jar-file is now located in core/target
.
The Stratosphere Program
Now we have everything prepared to run the Stratosphere program. I only ran it on my local computer, out of Eclipse. To do that, check out the code …
git clone https://github.com/stratosphere/stratosphere-mongodb-example.git
… and import it as a Maven project into your Eclipse. You have to manually add the previously built mongo-hadoop jar-file as a dependency. You can now press the “Run” button and see how Stratosphere executes the little program. It was running for about 8 seconds on the 1.5 GB dataset.
The result (located in /tmp/enronCountByDay
) now looks like this.
11,Fri Sep 26 10:00:00 CEST 1997
154,Tue Jun 29 10:56:00 CEST 1999
292,Tue Aug 10 12:11:00 CEST 1999
185,Thu Aug 12 18:35:00 CEST 1999
26,Fri Mar 19 12:33:00 CET 1999
There is one thing left I want to point out here. MongoDB represents objects stored in the database as JSON-documents. Since Stratosphere’s standard types do not support JSON documents, I was using the WritableWrapper
here. This wrapper allows to use any Hadoop datatype with Stratosphere.
The following code example shows how the JSON-documents are accessed in Stratosphere.
public void map(Record record, Collector<Record> out) throws Exception {
Writable valWr = record.getField(1, WritableWrapper.class).value();
BSONWritable value = (BSONWritable) valWr;
Object headers = value.getDoc().get("headers");
BasicDBObject headerOb = (BasicDBObject) headers;
String date = (String) headerOb.get("Date");
// further date processing
}
Please use the comments if you have questions or if you want to showcase your own MongoDB-Stratosphere integration.

This is very slow without the change
, and fast (~1s) with it. I don't really understand norm_num
so I'm at a loss as to why.
The slow version finishes the tactic quickly, but then it seems that the resulting proof is expensive to check.
example : 2^36 =<PHONE_NUMBER>6 := begin -- change 1*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2 = _, norm_num, end
It's doing kernel computation when it shouldn't -- it's instant if you do it in an arbitrary ring instead of nat
. Not sure why.
No support for nat.pow
I guess. The pow
instance for nat is not monoid.pow
I don't think that's it. norm_num
finds the same proof for both nat
and the arbitrary ring.

Welcome to my personal website!
You could know many things about me, especially relevant to computer science.
Sep, 2012
I entered Hunan University and started to study my first CS course, Introduction to Computer Science. This course was based on C language.
Mar, 2013
I took the National Computer Rank Examination (NCRE) of C Programming Language. To pass this exam, I read two books (more than 600 pages) and finished all exercises within one month. Due to my good preparations, I completed the exam in only half of the required time, and I was the first person to leave the exam room. Finally, I passed this exam and got an A-level certificate.
Apr, 2013
I was taking my second CS course, Fundamentals of Programming. My teacher assigned a project that was difficult for novices. I still remembered some details though many years had passed. This project was a poker game, which required us to implement functions like shuffle, sorting, comparison and so on. Only a few students completed this project and I was one of them. My work impressed my teacher, and he promised that he would teach me how to implement multiplayer functionality. However, he didn’t do it. And this became one of the regrets of my college days.
Sep, 2016
I became a graduate and focused on the research about bridge weigh-in-motion (BWIM). BWIM theory is to get the weight of moving vehicles without interrupt traffic. I studied the influence line (IL) algorithm and came up a modified IL algorithm to considering the change of vehicle speed. The algorithm was implemented via MATLAB.
Sep, 2020
I decided to study python systematically due to the popularity of it, and Python for Everybody is my first python course. It was a good start to continue my computer science study.

Adds the following capabilities: - Methods for handling the addition and removal of {@link Ext.form.Labelable} and {@link Ext.form.field.Field} instances at any depth within the container. - Events ({@link #fieldvaliditychange} and {@link #fielderrorchange}) for handling changes to the state of individual fields at the container level. - Automatic application of {@link #fieldDefaults} config properties to each field added within the container, to facilitate uniform configuration of all fields. This mixin is primarily for internal use by {@link Ext.form.Panel} and {@link Ext.form.FieldContainer}, and should not normally need to be used directly. * @markdown * @docauthor Jason Johnston<EMAIL_ADDRESS>*/ Ext.define('Ext.form.FieldAncestor', { /** * @cfg {Object} fieldDefaults *
If specified, the properties in this object are used as default config values for each * {@link Ext.form.Labelable} instance (e.g. {@link Ext.form.field.Base} or {@link Ext.form.FieldContainer}) * that is added as a descendant of this container. Corresponding values specified in an individual field's * own configuration, or from the {@link Ext.container.Container#defaults defaults config} of its parent container, * will take precedence. See the documentation for {@link Ext.form.Labelable} to see what config * options may be specified in the <tt>fieldDefaults</tt>.
 *
Example:
 *
new Ext.form.Panel({ fieldDefaults: { labelAlign: 'left', labelWidth: 100 }, items: [{ xtype: 'fieldset', defaults: { labelAlign: 'top' }, items: [{ name: 'field1' }, { name: 'field2' }] }, { xtype: 'fieldset', items: [{ name: 'field3', labelWidth: 150 }, { name: 'field4' }] }] });
 *
In this example, field1 and field2 will get labelAlign:'top' (from the fieldset's <tt>defaults</tt>) * and labelWidth:100 (from <tt>fieldDefaults</tt>), field3 and field4 will both get labelAlign:'left' (from * <tt>fieldDefaults</tt> and field3 will use the labelWidth:150 from its own config.

time-to-read example
President Obama notched several incremental victories this week in his push for congressional approval of a strike in Syria -- winning the support of congressional leaders and, on Wednesday, the backing of a key Senate panel.
But the president and his allies on the Hill are facing evident headwinds from rank-and-file members still not convinced that it's in the U.S. interest to launch missiles at Syria.
"It's going to be very difficult for [the president] to convince me the United States should be involved," Rep. Matt Salmon, R-Ariz., told FoxNews.com. "I'm not seeing any threat to our national security."
Some of the strongest voices in opposition are coming from the Republican wing of Capitol Hill. Secretary of State John Kerry got a grilling from skeptical Republicans during the House Foreign Affairs Committee hearing on Wednesday afternoon; the hearing was far more contentious than one on the Senate side a day earlier.
While leaders of the Republican-led House said Tuesday they would support a strike as punishment for Syrian President Bashar Assad's recent chemical weapons attack, many conservative members are openly opposed -- or at least undecided.
Salmon made his comments minutes before the start of the House Foreign Affairs Committee hearing. The congressman also said the administration doesn't appear to have the House votes right now.
"I don't think a majority of the Republican conference will support this," Salmon said. "And I suspect some Democrats will defect."
Earlier in the day, Michigan Republican Rep. Justin Amash tweeted: "If members of Congress care at all what constituents think, they will not authorize strikes in #Syria. "Never seen an action w/ less support."
On Monday, South Carolina Republican Reps. Trey Gowdy and Jeff Duncan also said they did not support a strike.
"The case has not been made to me of why the United States should be involved in Syria," Gowdy said at a home state rally he attended with Duncan, according to the Greenville (S.C.) News.
"I don't see where any imminent threat to the United States is evident," Duncan said.
The comments reflect numerous polls which show a strike in Syria does not enjoy widespread popularity among the public. The administration is arguing that it is still in the U.S. interest to respond, because inaction would embolden America's enemies to use chemical weapons again.
Duncan got into a tense exchange with Kerry on Wednesday at the House hearing during which he suggested Syria was an attempted diversion from the administration's lingering credibility problems over such issues as the fatal Benghazi terror attack and the failed Fast and Furious gun-tracking operation.
"We're talking about gassing people, and you're talking about Fast and Furious," a visibly agitated Kerry responded.
Other House members also expressed their opposition at the hearing.
"This will not stop the butchery and the killing," said Pennsylvania Republican Rep. Thomas Marino. "So what is the end game?"
Liberal Democrats are also raising concerns. During Tuesday's Senate hearing, one of the toughest questioners was Sen. Tom Udall, D-N.M.
Still, the Senate Foreign Relations Committee approved a resolution on Wednesday that supports a limited strike. And Senate Majority Leader Harry Reid, D-Nev., has voiced his support as well.
The only holdout among congressional leaders appears to be Senate Minority Leader Mitch McConnell, who, after meeting Tuesday with Obama, said: "Congress and our constituents would all benefit from knowing more about what it is he thinks needs to be done -- and can be accomplished -- in Syria and the region."
McConnell, R-Ky., is facing a tough re-election effort in 2014 with a strong challenge from the right. All House members face re-election next year, though they do not have to worry about any this fall.
Amash and Salmon are among several House members who have butted heads with House leadership and show no indication of going along this time with House Speaker John Boehner and Majority Leader Eric Cantor, who have expressed their support for a strike.


Abidal explains the complications Barcelona had signing De Jong
Barça's sporting director spoke exclusively to SPORT about a range of topics
by Ernest FolchEric Abidal spoke exclusively to SPORT about a range of issues surrounding Barcelona in the current day. Among other issues, the sporting director spoke about the summer signings.
Tell us about your vision for De Jong.
Ajax's philosophy is similar to Barça's and that helps. He's a player that adds a lot in the middle of the pitch, that can play in many positions, that understands the game well. He's a good passer and he helps the coach a lot. The most important thing is that he is a player with ambition. He's a player that's come here because he wants to win important trophies. Frenkie is an example of the type of player this club must look for. He's come to a foreign country with the hunger to win everything.
His signing was complicated.
There was a good fight (for his signature) between clubs because we're talking about a top player. It was not easy, but we managed it. We travelled (to Amsterdam) and we explained the project we had so that he could understand what Barça is. And Frenkie understood.
Junior Firpo?
I don't know if he started badly. If we're talking about performances, Barça is not Real Betis. Barça play position-based football and he has to understand and adapt. Play with and without the ball. He's a player with a lot of potential. He could be one of the best left-backs in the world. I always tell him that he must work hard and be aware of the (style of) play. He's going to get better, for sure. It's always difficult to get started at Barça.
Neto in goal...
In Barça you need top goalkeepers and there's no first or second (choice). The two goalkeepers we have must be first (choice) and ready to play. There were doubts about his signing and the press spoke about it a lot, but in preseason he showed what he can do. There is competition in goal and that helps both goalkeepers. (Japser) Cillessen wanted to play and communicated that to us. He was happy, but he wanted to leave to have more minutes and we understood. We spoke and it helped that Neto could come. We have a top goalkeeper.-

- piecewise-regression
fitting straight line models with breakpoints

- Version
1.3.0
- Github
- Documentation
https://piecewise-regression.readthedocs.io/en/master/index.html
- Paper
Easy-to-use piecewise regression (aka segmented regression) in Python. For fitting straight lines to data where there are one or more changes in gradient (known as breakpoints). Based on Muggeo’s paper “Estimating regression models with unknown break-points” (2003).
When using the package, please cite the accompanying paper.
Example:
Code examples below, and more in this Google Colab Jupyter Notebook.
Installation
You can install piecewise-regression using python’s pip package index
pip install piecewise-regression
The package is tested on Python 3.7, 3.8, 3.9 and 3.10.
Getting started
The package requires some x and y data to fit. You need to specify either a) some initial breakpoint guesses as start_values or b) how many breakpoints you want to fit as n_breakpoints (or both). Here is an elementary example, assuming we already have some data x and y:
import piecewise_regression
pw_fit = piecewise_regression.Fit(x, y, n_breakpoints=2)
pw_fit.summary()
Example
For demonstration purposes, substitute with your own data to fit.
Start-off generating some data with a breakpoint:
import piecewise_regression import numpy as np alpha_1 = -4 alpha_2 = -2 constant = 100 breakpoint_1 = 7 n_points = 200 np.random.seed(0) xx = np.linspace(0, 20, n_points) yy = constant + alpha_1*xx + (alpha_2-alpha_1) * np.maximum(xx - breakpoint_1, 0) + np.random.normal(size=n_points)
Fit the model:
# Given some data, fit the model pw_fit = piecewise_regression.Fit(xx, yy, start_values=[5], n_breakpoints=1) # Print a summary of the fit pw_fit.summary()
Example output:

This includes estimates for all the model variables, along with confidence intervals. NOTE: The Davies hypothesis test for the existence of at least one breakpoint is not reported, and is under development and testing.
Optional: Plotting the data and model results:
import matplotlib.pyplot as plt # Plot the data, fit, breakpoints and confidence intervals pw_fit.plot_data(color="grey", s=20) # Pass in standard matplotlib keywords to control any of the plots pw_fit.plot_fit(color="red", linewidth=4) pw_fit.plot_breakpoints() pw_fit.plot_breakpoint_confidence_intervals() plt.xlabel("x") plt.ylabel("y") plt.show() plt.close()
You can extract data as well:
# Get the key results of the fit
pw_results = pw_fit.get_results()
pw_estimates = pw_results["estimates"]
How It Works
The package implements Muggeo’s iterative algorithm (Muggeo “Estimating regression models with unknown break-points” (2003)) to find breakpoints quickly. This method simultaneously fits breakpoint positions and the linear models for the different fit segments, and it gives confidence intervals for all the model estimates. See the accompanying paper for more details.
Muggeo’s method doesn’t always converge on the best solution - sometimes, it finds a locally optimal solution or doesn’t converge at all. For this reason, the Fit method also implements a process called bootstrap restarting which involves taking a bootstrapped resample of the data to try to find a better solution. The number of times this process runs can be controlled with n_boot. To run the Fit without bootstrap restarting, set n_boot=0
.
If you do not have (or do not want to use) initial guesses for the number of breakpoints, you can set it to n_breakpoints=3
, and the algorithm will randomly generate start_values. With a 50% chance, the bootstrap restarting algorithm will either use the best currently converged breakpoints or randomly generate new start_values
, escaping the local optima in two ways in order to find better global optima.
As is often the case with fitting non-linear models, even with these measures, the algorithm is not guaranteed to converge to a global optimum. However, increasing n_boot
raises the probability of global convergence at the cost of computation time.
Model Selection
In addition to the main Fit tool, the package also offers a ModelSelection option based on the Bayesian Information Criterion (BIC). This additional tool is experimental and not as thorough as the main Fit function. In particular, the models are generated with random start_values, which can influence the model fit and give different values for the BIC. The tool can help explore other possible models but should not be used to choose the best model at this time.
ms = piecewise_regression.ModelSelection(x, y, max_breakpoints=6)
Example output:

The data of the model fits can be accessed in

Community Guidelines and Contributing
We welcome community participation!
Sourced from Open Source Guide: How to contribute.
Open an issue in the following situations:
Report an error you can’t solve yourself
Discuss a high-level topic or idea (for example, community, vision or policies)
Propose a new feature or other project ideas
Tips for communicating on issues:
If you see an open issue that you want to tackle, comment on the issue to let people know you’re on it. That way, people are less likely to duplicate your work.
If an issue was opened a while ago, it’s possible that it’s being addressed somewhere else, or has already been resolved, so comment to ask for confirmation before starting work.
If you opened an issue, but figured out the answer later on your own, comment on the issue to let people know, then close the issue. Even documenting that outcome is a contribution to the project.
Open a pull request in the following situations:
Submit trivial fixes (for example, a typo, a broken link or an obvious error)
Start work on a contribution that was already asked for, or that you’ve already discussed, in an issue
Tips for submitting PRs:
Reference any relevant issues or supporting documentation in your PR (for example, “Closes #37.”)
Include screenshots of the before and after if your changes include differences in HTML/CSS. Drag and drop the images into the body of your pull request.
Test your changes by running them against any existing tests if they exist and create new ones when needed. Whether tests exist or not, make sure your changes don’t break the existing project.
Contribute in the style of the project to the best of your abilities.

If you already have an object named PageableCollection
attached to the
Backbone
module, you can use this to return a local reference to this
PageableCollection class and reset the name PageableCollection to its
previous definition.
// The left hand side gives you a reference to this // PageableCollection implementation, the right hand side // resets PageableCollection to your other PageableCollection. var PageableCollection = PageableCollection.noConflict();
PageableCollection
:
State change event. Fired when PageableCollection#state gets updated
Drop-in replacement for Backbone.Collection. Supports server-side and client-side pagination and sorting. Client-side mode also support fully multi-directional synchronization of changes between pages.
Extends Backbone.Collection
The container object to store all pagination states.
You can override the default state by extending this class or specifying
them in an options
hash to the constructor.
(number)
: = 1 - The first page index. Set to 0 if
your server API uses 0-based indices. You should only override this value
during extension, initialization or reset by the server after
fetching. This value should be read only at other times.
(number)
: = null - The last page index. This value
is
read only
and it's calculated based on whether
firstPage
is 0 or
1, during bootstrapping, fetching and resetting. Please don't change this
value under any circumstances.
(number)
: = null - The current page index. You
should only override this value during extension, initialization or reset
by the server after fetching. This value should be read only at other
times. Can be a 0-based or 1-based index, depending on whether
firstPage
is 0 or 1. If left as default, it will be set to
firstPage
on initialization.
(number)
: = 25 - How many records to show per
page. This value is
read only
after initialization, if you want to
change the page size after initialization, you must call
PageableCollection#setPageSize.
(number)
: = null - How many pages there are. This
value is
read only
and it is calculated from
totalRecords
.
(number)
: = null - How many records there
are. This value is
required
under server mode. This value is optional
for client mode as the number will be the same as the number of models
during bootstrapping and during fetching, either supplied by the server
in the metadata, or calculated from the size of the response.
(string)
: = null - The model attribute to use for
sorting.
(number)
: = -1 - The order to use for sorting. Specify
-1 for ascending order or 1 for descending order. If 0, no client side
sorting will be done and the order query parameter will not be sent to
the server during a fetch.
(string)
: = "server" The mode of operations for this
collection.
"server"
paginates on the server-side,
"client"
paginates
on the client-side and
"infinite"
paginates on the server-side for APIs
that do not support
totalRecords
.
A translation map to convert PageableCollection state attributes to the query parameters accepted by your server API.
You can override the default state by extending this class or specifying
them in options.queryParams
object hash to the constructor.
(Object)
: = {"-1": "asc", "1": "desc"} - A map for
translating a PageableCollection#state.order constant to the ones your
server API accepts.
Given a list of models or model attributues, bootstraps the full collection in client mode or infinite mode, or just the page you want in server mode.
If you want to initialize a collection to a different state than the
default, you can specify them in options.state
. Any state parameters
supplied will be merged with the default. If you want to change the
default mapping from PageableCollection#state keys to your server API's
query parameter names, you can specifiy an object hash in
option.queryParams
. Likewise, any mapping provided will be merged with
the default. Lastly, all Backbone.Collection constructor options are also
accepted.

This collection is the internal storage for the bootstrapped or fetched
models. You can use this if you want to operate on all the pages.
Makes a Backbone.Collection that contains all the pages.
(Object)
Options for Backbone.Collection constructor.
Backbone.Collection
:
Factory method that returns a Backbone event handler that responses to
the add

events. The returned event
handler will synchronize the current page collection and the full
collection's models.

Change the page size of this collection.
Under most if not all circumstances, you should call this method to change the page size of a pageable collection because it will keep the pagination state sane. By default, the method will recalculate the current page number to one that will retain the current page's models when increasing the page size. When decreasing the page size, this method will retain the last models to the current page that will fit into the smaller page size.
If options.first
is true, changing the page size will also reset the
current page back to the first page instead of trying to be smart.
For server mode operations, changing the page size will trigger a
PageableCollection#fetch and subsequently a reset
event.
For client mode operations, changing the page size will reset
the
current page by recalculating the current page boundary on the client
side.
If options.fetch
is true, a fetch can be forced if the collection is in
client mode.
(number)
The new page size to set to PageableCollection#state.

Switching between client, server and infinite mode.
If switching from client to server mode, the #fullCollection is emptied
first and then deleted and a fetch is immediately issued for the current
page from the server. Pass false
to options.fetch
to skip fetching.
If switching to infinite mode, and if options.models
is given for an
array of models,PageableCollection#links will be populated with a URL per
page, using the default URL for this collection.
If switching from server to client mode, all of the pages are immediately
refetched. If you have too many pages, you can pass false
to
options.fetch
to skip fetching.
If switching to any mode from infinite mode, thePageableCollection#links will be deleted.

Given a page index, set PageableCollection#state.currentPage to that
index. If this collection is in server mode, fetch the page using the
updated state, otherwise, reset the current page of this collection to
the page specified by index
in client mode. If options.fetch
is true,
a fetch can be forced in client mode before resetting the current
page. Under infinite mode, if the index is less than the current page, a
reset is done as in client mode. If the index is greater than the current
page number, a fetch is made with the results appended
toPageableCollection#fullCollection. The current page will then be reset
after fetching.

Overidden to make getPage
compatible with Zepto.
XMLHttpRequest
:
Parse pagination links from the server response. Only valid under infinite mode.
Given a response body and a XMLHttpRequest object, extract pagination links from them for infinite paging.
This default implementation parses the RFC 5988 Link
header and extract
3 links from it - first
, prev
, next
. Any subclasses overriding this
method must return an object hash having only the keys
above. However, simply returning a next
link or an empty hash if there
are no more links should be enough for most implementations.
(any)
The deserialized response body.
(Object)
| Name | Description |
|---|---|
options.xhr XMLHttpRequest
|
The XMLHttpRequest object for this response. |
Object
:
Parse server response data.
This default implementation assumes the response data is in one of two structures:
[ {}, // Your new pagination state [{}, ...] // An array of JSON objects ]
Or,
[{}] // An array of JSON objects
The first structure is the preferred form because the pagination states may have been updated on the server side, sending them down again allows this collection to update its states. If the response has a pagination state object, it is checked for errors.
The second structure is the Backbone.Collection#parse default.
*Note:** this method has been further simplified since 1.1.7. While existingPageableCollection#parse implementations will continue to work, new code is encouraged to overridePageableCollection#parseState andPageableCollection#parseRecords instead.
(Object)
The deserialized response data from the server.
(Object)
options for the ajax request
Array<Object>
:
An array of model objects
Parse server response for server pagination state updates. Not applicable under infinite mode.
This default implementation first checks whether the response has any
state object as documented inPageableCollection#parse. If it exists, a
state object is returned by mapping the server state keys to this
pageable collection instance's query parameter keys using queryParams
.
It is NOT neccessary to return a full state object complete with all
the mappings defined inPageableCollection#queryParams. Any state object
resulted is merged with a copy of the current pageable collection state
and checked for sanity before actually updating. Most of the time, simply
providing a new totalRecords
value is enough to trigger a full
pagination state recalculation.
parseState: function (resp, queryParams, state, options) { return {totalRecords: resp.total_entries}; }
If you want to use header fields use:
parseState: function (resp, queryParams, state, options) { return {totalRecords: options.xhr.getResponseHeader("X-total")}; }
This method MUST return a new state object instead of directly modifying the PageableCollection#state object. The behavior of directly modifying PageableCollection#state is undefined.
(Object)
The deserialized response data from the server.
(Object)
A copy of PageableCollection#queryParams.
(Object)
A copy of PageableCollection#state.
Object
:
A new (partial) state object.
Parse server response for an array of model objects.
This default implementation first checks whether the response has any state object as documented inPageableCollection#parse. If it exists, the array of model objects is assumed to be the second element, otherwise the entire response is returned directly.
(Object)
The deserialized response data from the server.
Array<Object>
:
An array of model objects
Fetch a page from the server in server mode, or all the pages in client mode. Under infinite mode, the current page is refetched by default and then reset.
The query string is constructed by translating the current pagination state to your server API query parameter usingPageableCollection#queryParams. The current page will reset after fetch.
XMLHttpRequest
:
Convenient method for making a comparator
sorted by a model attribute
identified by sortKey
and ordered by order
.
Like a Backbone.Collection, a PageableCollection will maintain the
current page in sorted order on the client side if a comparator
is
attached to it. If the collection is in client mode, you can attach a
comparator toPageableCollection#fullCollection to have all the pages
reflect the global sorting order by specifying an option full
to
true
. You must call sort
manually
orPageableCollection#fullCollection.sort after calling this method to
force a resort.
While you can use this method to sort the current page in server mode, the sorting order may not reflect the global sorting order due to the additions or removals of the records on the server since the last fetch. If you want the most updated page in a global sorting order, it is recommended that you set PageableCollection#state.sortKey and optionally PageableCollection#state.order, and then callPageableCollection#fetch.
Adjusts the sorting for this pageable collection.
Given a sortKey
and an order
, sets state.sortKey
and
state.order
. A comparator can be applied on the client side to sort in
the order defined if options.side
is "client"
. By default the
comparator is applied to thePageableCollection#fullCollection. Set
options.full
to false
to apply a comparator to the current page under
any mode. Setting sortKey
to null
removes the comparator from both
the current page and the full collection.
If a sortValue
function is given, it will be passed the (model, sortKey)
arguments and is used to extract a value from the model during
comparison sorts. If sortValue
is not given, model.get(sortKey)
is
used for sorting.


Search
After indexing, the search engine can access the index and search the respective databases. For this purpose, this component runs alongside the actual search through the interaction with the user. Here, the processing of the query, the relevance determination, and presentation of results will take place. To perform the search, this component first transformes the information needs of the user in an appropriate form of representation. Subsequently, a search and the subsequent ranking is performed. Recently the search engine presents the result set within the user interface. To generate the facets, the search engine also uses the metadata model.

Victory is your objective. To get there, either:
One after another, you and your opponent will have 3 actions to play. An
action is either a move or an attack.
A move is only possible if there is no other battalion on the arrival tile.
If an opponent battalion is there, the action will be considered as an
attack. An attack is possible within the range of the attacking battalion.
After an attack, if the defensive battalion is still alive and within range,
it will fight back. When a soldier or a knight kills a battalion, it moves
to the attacked tile.
At the beginning of a game, you compose your army and then position it around your castle. Units have 6 skills:
Soldiers are slow and shortsighted but they are resilient. Musketeers have a better vision and range but they can't fight hand-to-hand. Knights are fast and good scoot. Cannons make heavy damages and are capable of long shoots.

A responsive site is a website that can be viewed on any device with any sized screen. Responsiveness provides flexibility to the layout of a website so that however you resize your browser screen, the content shrinks and expands within the boundaries of the screen size. It also provides adjustability to a site allowing different parts of content to move around depending on the screen size.
This is when you start designing your site with a small or mobile screen in mind, rather than a larger (e.g.) desktop screen. Desgning like this is really beneficial because it is much easier to distribute content in a readable way when going from a small space to a big one, rather than vice versa.
Frameworks are a package of already structured files and folders containing standardised code. They are usually used at the beginning of the creation of a site because they contain alot of common structures already in use in webpages today, meaning you don't have to code your webpage from scratch.
To me, however, it seems like the biggest disadvantage of using frameworks is that you can easily get used to using them and be less creative when creating your webpage. I get the whole 'there's no need to reinvent the wheel' thing, but sometimes I think it's good to go into things with the abmition to reinvent it, even if you don't.
A wireframe is essentially a drawing or sketch of your webpage not including any design elements. Like the skeleton of your webpage. Drawing wireframe allows you to visually map out the heirarchical structure of your website and to play around with where things will go. It is also very important for communicating your ideas with clients. By showing them a wireframe a client is able to understand the funtionality of the page without being distracted by things like font, colour, sizing etc. which you will add later in the develoment process anyway. The wireframe can of course also be used as the template for the design process.
Definitely positioning. Honestly, I still don't really understand how to do this very well. Hence why my images above aren't positioned! I did manage to position an element beside another one on my index page but it was kind of a fluke. 'display:flex' is still very temperamental when I try to use it.

My favorite ex-Cub, Matt Murton was dealt a heavy blow this evening as the Colorado Rockies optioned him to Triple A Colorado Springs. That's pretty surprising considering Murton was hitting .302 with 2 HR's in Spring Training. Ex-White Sox Scott Podsednik and his .217 still has a spot on the roster, though.
Hang in there, my fellow pelo rojo.


Young is the young professional association of the Open University (OU) of The Netherlands, established in November 2010. The initial idea behind this association is to bring young professionals in contact with each other through informal activities.
The current goals for young is to further develop and maintain a professional business network of young professionals within the OU. We aim at strengthening the contacts among young people, the different departments within the OU and the external environment. The common denominator is not the age, but how we as young people want to place ourselves within society, how we cooperate and how we want to plan our careers accordingly.
To accomplish this yOUng organises targeted professional development activities in cooperation with departments within the OU, but also with external parties (e.g. other business networks) that share the same values and/or goals. To reinforce the relationship among young professionals within the OU, yOUng also offers a platform where members can organise social (informal) activities, supported by the board of yOUng.

The charming adventures of a data scientist and his solver.
Removing overlap of polygons in decision models.
In our last post...
It would be convenient if we had a device that allowed us to remove overlap between objects in arbitrary models.
One such device is the No-Fit Polygon (NFP).
The Minkowski Sum of two sets is...
$$ NFP_{AB} = \dots $$There exist a number of algorithms for generating NFPs for irregular polygons.
If we assume our polygons are convex...
