6.6 Error-Checking StrategiesMost programming languages that support exceptions are geared to raise exceptions only in very rare cases. Python's emphasis is different. In Python, exceptions are considered appropriate whenever they make a program simpler and more robust. A common idiom in other languages, sometimes known as "look before you leap" (LBYL), is to check in advance, before attempting an operation, for all circumstances that might make the operation invalid. This is not ideal, for several reasons:
The preferred idiom in Python is generally to attempt the operation in a try clause and handle the exceptions that may result in except clauses. This idiom is known as "it's easier to ask forgiveness than permission" (EAFP), a motto widely credited to Admiral Grace Murray Hopper, co-inventor of COBOL, and shares none of the defects of "look before you leap." Here is a function written using the LBYL idiom: def safe_divide_1(x, y): if y= =0: print "Divide-by-0 attempt detected" return None else: return x/y With LBYL, the checks come first, and the mainstream case is somewhat hidden at the end of the function. Here is the equivalent function written using the EAFP idiom: def safe_divide_2(x, y): try: return x/y except ZeroDivisionError: print "Divide-by-0 attempt detected" return None With EAFP, the mainstream case is up front in a try clause, and the anomalies are handled in an except clause. EAFP is most often the preferable error-handling strategy, but it is not a panacea. In particular, you must be careful not to cast too wide a net, catching errors that you did not expect and therefore did not mean to catch. The following is a typical case of such a risk (built-in function getattr is covered in Chapter 8): def trycalling(obj, attrib, default, *args, **kwds): try: return getattr(obj, attrib)(*args, **kwds) except AttributeError: return default The intention of function trycalling is to try calling a method named attrib on object obj, but to return default if obj has no method thus named. However, the function as coded does not do just that. It also hides any error case where AttributeError is raised inside the implementation of the sought-after method, silently returning default in those cases. This may hide bugs in other code. To do exactly what is intended, the function must take a little bit more care: def trycalling(obj, attrib, default, *args, **kwds): try: method = getattr(obj, attrib) except AttributeError: return default else: return method(*args, **kwds) This implementation of trycalling separates the getattr call, placed in the try clause and therefore watched over by the handler in the except clause, from the call of the method, placed in the else clause and therefore free to propagate any exceptions it may need to. Using EAFP in the most effective way involves frequent use of the else clause on try/except statements. 6.6.1 Handling Errors in Large ProgramsIn large programs, it is especially easy to err by making your try/except statements too wide, particularly once you have convinced yourself of the power of EAFP as a general error-checking strategy. A try/except is too wide when it catches too many different errors or an error that can occur in too many different places. The latter is a problem if you need to distinguish exactly what happened and where, and the information in the traceback is not sufficient to pinpoint such details (or you discard some or all of the information in the traceback object). For effective error handling, you have to keep a clear distinction between errors and anomalies that you expect (and thus know exactly how to handle), and unexpected errors and anomalies, which indicate a bug somewhere in your program. Some errors and anomalies are not really erroneous, and perhaps not even all that anomalous: they are just special cases, perhaps rare but nevertheless quite expected, which you choose to handle via EAFP rather than via LBYL to avoid LBYL's many intrinsic defects. In such cases, you should just handle the anomaly, in most cases without even logging or reporting it. Be very careful, under these circumstances, to keep the relevant try/except constructs as narrow as feasible. Use a small try clause that doesn't call too many other functions, and very specific exception-class lists in the except clauses. Errors and anomalies that depend on user input or other external conditions not under your control are always expected to some extent, precisely because you have no control on their underlying causes. In such cases, you should concentrate your effort on handling the anomaly gracefully, normally reporting and logging its exact nature and details, and generally keep your program running with undamaged internal and persistent states. The width of try/except clauses under such circumstances should also be reasonably narrow, although this is not quite as crucial as when you use EAFP to structure your handling of not-really-erroneous special cases. Lastly, entirely unexpected errors and anomalies indicate bugs in your program's design or coding. In most cases, the best strategy regarding such errors is to avoid try/except and just let the program terminate with error and traceback messages. (You might even want to log such information and/or display it more suitably with an application-specific hook in sys.excepthook, as we'll discuss shortly.) If your program must keep running at all costs, even under such circumstances, try/except statements that are quite wide may be appropriate, with the try clause guarding function calls that exercise vast swaths of program functionality and broad except clauses. In the case of a long-running program, make sure all details of the anomaly or error are logged to some persistent place for later study (and that some indication gets displayed, too, so that you know such later study is necessary). The key is making sure that the program's persistent state can be reverted to some undamaged, internally consistent point. The techniques that enable long-running programs to survive some of their own bugs are known as checkpointing and transactional behavior, but they are not covered further in this book. 6.6.2 Logging ErrorsWhen Python propagates an exception all the way to the top of the stack without finding an applicable handler, the interpreter normally prints an error traceback to the standard error stream of the process (sys.stderr) before terminating the program. You can rebind sys.stderr to any file-like object usable for output in order to divert this information to a destination more suitable for your purposes. When you want to change the amount and kind of information output on such occasions, rebinding sys.stderr is not sufficient. In such cases, you can assign your own function to sys.excepthook, and Python will call it before terminating the program due to an unhandled exception. In your exception-reporting function, you can output whatever information you think will later help you diagnose and debug the problem to whatever destinations you please. For example, you might use module traceback (covered in Chapter 17) to help you format stack traces. When your exception-reporting function terminates, so does your program. 6.6.3 The assert StatementThe assert statement allows you to introduce debugging code into a program. assert is a simple statement with the following syntax: assert condition[,expression] When you run Python with the optimize flag (-O, as covered in Chapter 3), assert is a null operation: the compiler generates no code. Otherwise, assert evaluates condition. If condition is satisfied, assert does nothing. If condition is not satisfied, assert instantiates AssertionError with expression as the argument (or without arguments, if there is no expression) and raises the resulting instance. assert statements are an effective way to document your program. When you want to state that a significant condition C is known to hold at a certain point in a program's execution, assert C is better than a comment that just states C. The advantage of assert is that when the condition does not in fact hold, assert alerts you to the problem by raising AssertionError. 6.6.4 The _ _debug_ _ Built-in VariableWhen you run Python without option -O, the _ _debug_ _ built-in variable is True. When you run Python with option -O, _ _debug_ _ is False. Also, with option -O, the compiler generates no code for an if statement whose condition is _ _debug_ _. To exploit this optimization, surround the definitions of functions that you call only in assert statements with if _ _debug_ _. This technique makes compiled code smaller and faster when Python is run with -O, and enhances program clarity by showing that the functions exist only to perform sanity checks. |

## RegEx
### Crash Course
## Transition Styles
[None](?transition=none#/settings) -
[Fade](?transition=fade#/settings) -
[Slide](?transition=slide#/settings) -
[Convex](?transition=convex#/settings) -
[Concave](?transition=concave#/settings) -
[Zoom](?transition=zoom#/settings)
## Why RegEx?
- Unbelievably Powerful
- highly reusable and highly portable
- Solve countless day to day problems
- Widely Supported
## What is RegEx?
A pattern matching language. Yes, a language!
A regex is a string. For instance, `foo` is a regex. so is `[A-Z+:\d+]`
There's a beautiful language behind that obfuscated mess of characters.
## Simple Expressions
Let us start with basic patterns without weird characters.
`abc`
a thing, followed by another thing, followed another thing!
## Simple Expressions
| pattern | matches |
| --- | --- |
| `abc` | `abc,abcd,zabc` |
| 123 | `1234,abc123,za234123bc` |
| `a1` | `a1,a1bc,a12b2c` |
## Meta characters
Characters with special meaning to them.
`^ [] () {} . * \ | + $` and sometimes `-`
## Match Any Character with `.`
Matches any character. (Wild card)
`s.n` matches `san`, `sun`, `son` and etc.
## Line Anchors: `^` and `$`
`^` - Start of Line; `$` - End of Line
| pattern | matches |
| --- | --- |
| `^Hi` | line starts with `Hi` |
| `Hello$` | line ends with `Hello` |
| `^san$` | line that has only `san` |
| `^$` | Empty line |
## Character Class: `[]`
match any one of several characters.
gr[ea]y - "`g`, followed by `r`, followed by **either an `e` or an `a`**, followed by y."
If you use `[^...]` instead of `[...]`, the class matches any character that's not in the character class.
## Character Class Metacharacter: `-`
specify range between two characters
| pattern | matches |
| --- | --- |
| `[a-c]` | Any of `a b c` |
| `[0-9]` | Any of `0 1 2 3 4 5 6 7 8 9` |
| `[A-Za-z]` | Any of the English alphabet |
`[012345abcedfABCDEF]` is same as `[0-5a-fA-F]`
## Alternation Metacharacter: `|`
`|` means `either` - combines two expressions into one
`Mike` and `Michael` are separate, but `Mike|Micheal` is one that matches either.
## Matching Optional Items: `?`
placed after a character that is allowed, but not required, at a certain position in an expression.
`flavou?r` - matches flavor (US), flavour (UK)
"`f`, followed by `l`, followed by `a`, followed by `v`, followed by `o`, followed by an `optional u`, followed by `r`."
## Other Quantifiers: `+` and `*`
number of times the preceding character can appear in an expression
| Character | Meaning |
| --- | --- |
| `?` | `0` or `1` |
| `+` | `1` or more |
| `*` | `0` or more |
## Interval Quantifier: `{}`
`{min,max}` metasequence specifies number of times an item can match
**TODO**: add example
## Escape Character: `\`
`\` escapes metacharacters so you can match those in patterns.
**TODO**: add example
## Paranthesis for Grouping: `()`
`http://([^/]+)` - matches the domain part alone.
`http://github.com/sanspace`
`github.com`
`[^/]+` is grouped as subportion of the expression
## Examples - Username
Requirements
- Alphanumeric
- No special characters except underscore
- Minimum 8 characters, Maximum 16 characters
`^[a-zA-Z0-9_]{3,16}$`
## Match an IP address
<IP_ADDRESS>
## Not so fast
> Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems.
## Not so fast
> not that regular expressions are evil, per se, but that __overuse__ of regular expressions is evil.
## Not so fast
- Know the flavors of different programming languages
- Know what you are doing
- RegEx could be slow for complex patterns

Love Island’s Maura Higgins leads the best-dressed celebs on the ITV Palooza red carpet
TV stars were out in force for ITV Palooza, the annual event which celebrates the channel’s showbiz successes.
Alongside presenters Holly Willoughby and Susanna Reid there was reality TV royalty in the form of Gemma Collins and fellow TOWIE alumni Jess Wright with brother Mark.
Plus, there was a major Love Island reunion, with contestants from the last two series of the dating show bringing plenty of glitz and glam to proceedings.
Here’s who wowed on the red carpet…
Maura Higgins
The outspoken Irish star of Love Island 2019 was a vision in lace, her plunging black gown accessorised with a statement belt, mini bag and strappy heels.
Holly Willoughby
TV presenter and fashion icon Holly Willoughby looked simply stunning in a black velvet midi dress with chain detailing by Christopher Kane, which she teamed with black Gina court heels.
Amber Gill and Yewande Biala
Love Island besties Amber Gill and Yewande Biala were the golden girls of the night, appearing on the red carpet together in sparky figure-hugging gowns.
Meghan McKenna

Georgia Steel
We don’t know if she was inspired by Zoolander’s famous ‘blue steel’ pose but Love Island 2018 favourite Georgia Steel royal blue frock was a real show-stopper, the mini wrap dress featuring an extra-long train.
Zara McDermott
Steel’s Love Island BFF Zara McDermott also opted for a blue outfit, her navy satin gown accessorised with sparkly silver peep-toe heels.
Jess Wright
Black was a big trend on the ITV Palooza red carpet and Jess Wright was one of many celebs who choose a monochrome ensemble. The former TOWIE star teamed her simple black crop top and skirt with a cool art deco-style clutch.
Caroline Flack
While all the Love Islanders opted for skimpy or bodycon dresses, series host Caroline Flack stuck to her signature style, looking chic in a sequinned shorts suit worn with a black roll neck and an on-trend beaded bag.

Sensex falls 70 pts in early trade; banking stocks drag
by PTIEquity benchmark BSE Sensex on Monday fell over 70 points in early trade, dragged mainly by losses in financial and banking stocks amid persistent foreign fund outflows.
The 30-share index was trading 73.38 points or 0.18 per cent lower at 40,371.77 in morning trade; while the broader Nifty was trading 26.10 points or 0.22 per cent down at 11,895.40.
In the previous session, Sensex settled at 40,445.15, down 334.44 points or 0.82 per cent. Likewise, the 50-share Nifty shed 96.90 points or 0.81 per cent to close at 11,921.50.
Bajaj Finance was the biggest loser in the Sensex pack with a decline by 1.28 per cent in morning deals, followed by HUL, ITC, SBI, Kotak Mahindra Bank, Tech Mahindra, TCS and Axis Bank.
On the other hand, Maruti, Vedanta, Tata Steel, HDFC, Tata Motors and Sun Pharma emerged as the gainers, rising up to 1.72 per cent.
Meanwhile, the rupee appreciated by 10 paise to 71.10 in early session on Monday.
Foreign institutional investors (FIIs) offloaded shares worth Rs 867.66 crore in the capital market on Friday, while domestic institutional investors purchased shares to the tune of Rs 210.72 crore, data available with the stock exchange showed.
Asian stocks were trading mostly higher on Monday following strong US job data amid weak Chinese exports.
American employers added 266,000 jobs in November, according to the Labor Department data released on Friday.
Marking the fourth straight fall, Chinese exports declined 1.1 in November compared to the same month a year earlier, mainly dragged by weaker shipments to the US that fell 23 per cent.
Brent futures, the global oil benchmark, fell 0.33 per cent to USD 64.18 per barrel.


Football: Man City defender Mendy given France recall
PARIS: Manchester City defender Benjamin Mendy was recalled to the France squad on Thursday (Nov 7) for the upcoming Euro 2020 qualifiers against Moldova and Albania.
Left-back Mendy, 25, was part of the squad that won the 2018 World Cup in Russia but has not played for his country since winning his ninth cap in a UEFA Nations League game against the Netherlands in September last year.
France are without goalkeeper and captain Hugo Lloris, who has just undergone surgery on a dislocated elbow, as they look to clinch their place at next year's Euro 2020 finals.
Paul Pogba and Lucas Hernandez are also sidelined, but Kylian Mbappe returns after the Paris Saint-Germain striker was forced to withdraw from the last squad due to fitness problems.
Olivier Giroud is also included by coach Didier Deschamps despite a lack of game time at his club Chelsea. The 33-year-old scored in each of France's matches last month, netting from the penalty spot in a 1-0 win in Iceland and then heading in as Les Bleus drew 1-1 at home with Turkey.
Lyon right-back Leo Dubois and Real Betis forward Nabil Fekir are also named in the squad but there is no place for Barcelona centre-back Samuel Umtiti.
France are level at the top of qualifying Group H with Turkey on 19 points, four points clear of Iceland with two matches remaining and the top two advancing to the 24-team finals.
A win against 175th-ranked Moldova at the Stade de France on Thursday, November 14 will clinch qualification, although they could be assured progress before that game kicks off, provided Iceland fail to beat Turkey in Istanbul.
They finish their campaign in Albania on Sunday, Nov 17.
France squad
Goalkeepers: Alphonse Areola (Real Madrid/ESP), Mike Maignan (Lille), Steve Mandanda (Marseille)
Defenders: Lucas Digne (Everton/ENG), Leo Dubois (Lyon), Presnel Kimpembe (Paris Saint-Germain), Clement Lenglet (Barcelona/ESP), Benjamin Mendy (Manchester City/ENG), Benjamin Pavard (Bayern Munich/GER), Raphael Varane (Real Madrid/ESP), Kurt Zouma (Chelsea/ENG)
Midfielders: N'Golo Kante (Chelsea/ENG), Blaise Matuidi (Juventus/ITA), Tanguy Ndombele, Moussa Sissoko (both Tottenham Hotspur/ENG), Corentin Tolisso (Bayern Munich/GER)
Forwards: Wissam Ben Yedder (Monaco), Kingsley Coman (Bayern Munich/GER), Nabil Fekir (Real Betis/ESP), Olivier Giroud (Chelsea/ENG), Antoine Griezmann (Barcelona/ESP), Thomas Lemar (Atletico Madrid/ESP), Kylian Mbappe (Paris Saint-Germain)

In today’s cyberthreat environment, security teams are up against a constant flood of incoming risks. But with advanced security analytics, machine learning, and their own intuition, security experts are fighting back with agile, adaptable defense systems. While security teams comb through tens of thousands of cybersecurity alerts-trying to separate legitimate risks from the noise—attacks can slip through the cracks unnoticed and do significant damage.
There’s too much to handle:
Microsoft 365 Defender is an integrated, cross-domain threat detection and response solution. It provides organizations with the ability to prevent, detect, investigate. and remediate sophisticated cross-domain attacks within their Microsoft 365 environments. Microsoft 365 Defender leverages raw signal data from individual service domains - user identity, endpoints, applications, email, and collaboration tools, normalizing the data at the ingestion point.
The data is analyzed and low-level signals that may otherwise be missed as well as individual alerts are correlated into incidents. This gives a complete view of an attack that can be responded to in its entirety. Powerful workflows and AI autoheal affected assets. Advanced hunting capabilities mean organizations can use their proprietary knowledge to uncover sophisticated breaches and customize their responses. But, Microsoft 365 Defender requires no specific expertise or customization, so defenders can immediately use the integrated console and combined incident views.
With Microsoft 365 Defender, security teams can:

To dynamically identify new threats, Windows Defender Antivirus (part of Microsoft Defender for Endpoint) works with large sets of interconnected data in the Microsoft Intelligent Security Graph and powerful artificial intelligence (AI) systems driven by advanced machine learning models.
The Microsoft Graph Security API is a unified API that provides a standard interface and uniform schema to integrate security alerts and threat intelligence from multiple sources, enrich alerts and data with contextual information, and automate security operations. The security API is part of the Microsoft Graph, which is a unified REST API for integrating data and intelligence from Microsoft and partner products and services. Using Microsoft Graph, customers and partners can rapidly build solutions that authenticate once and use a single API call to access or act on security insights from multiple security solutions. Additional value is uncovered when you explore the other Microsoft Graph entities (Office 365, Azure Active Directory, Intune, and more) to tie business context with your security insights.


Cryptoshares factory smart contract address:
{{factoryContract._address}}
'CryptoShares Factory' is a smart contract for creating smart contract for cryptoshares.
They can be shares of a real corporation. Every share is an ERC20 + ERC223 token.
Every smart contracts with cryptoshares created with 'CryptoShares Factory' implements:
Smart contract can receive Ether and xEUR tokens and distribute them to shareholders.
Shares can be transferred without restrictions from one Ethereum address to another. But only verified Ethereum address represents shareholder. Every share not owned by registered shareholder address is considered 'in transfer', shares 'in transfer' can not vote and can not receive dividends.
'CryptoSharesFactory' charges fee in Ether for creating cryptoshares smart contracts.

This isn't really a trip report, but something interesting happened to me a few hours ago as I was (unsuccessfully) trying to get to sleep.
I'm on day 3 of what's looking like a severe head/chest cold. As of yet I haven't taken anything to treat it, other than echinacea and 1000mg vitamin C tablets twice a day (this usually works for me, but not this time), so I'm not sure what induced what happened.
I haven't been sleeping well the past few nights, so naturally I'm exhausted. But sleep won't come - the nasal/bronchial irritiation sees to that. Tonight I turned the heat up a bit, pulled the covers over my head, got as relaxed as possible, and tried to clear my mind by counting my heartbeats (this often works for me).
I'm not sure how long I was lying there (seemed like hours), but I started to notice a 'strobing' white light, maybe 10Hz or so. Keep in mind that I can't see anything else, there's no light whatsoever under the covers. This passed quickly, then I noticed the swirling multi-coloured 'plasma' floating in front of me. It got brighter and more colourful by the minute, until I thought to myself how strange this was, then it disappeared. This was the first thought I'd had in a while - I'd lost track of my count long ago. Now my mind started to fill with all kinds of thoughts, memories, all very eery. I started 'day-dreaming', in total darkness, in a sort of disembodied-like state, I was unaware that I had a body - I was *not* dreaming, I was definitely conscious.
Then a coughing-fit set in, and brought me out of it. I became acutely aware that I had a body, unfortunately. A look at the clock showed me I'd been attempting sleep for about two hours. Two hours later and I'm still very awake, writing this report.

Kremlin Cannot Interfere in Yandex's Corporate Management Structure Change - Spokesman
MOSCOW (Sputnik) - Russia's top technology company Yandex did not agree its corporate governance change with the Kremlin, which has no right to interfere in such decisions, Russian presidential spokesman Dmitry Peskov said Monday.
"Of course, there is no question of negotiating this with the Kremlin. These are corporate affairs that do not need to be agreed with the Kremlin," Peskov said.
When asked if this format could be used in other large Russian IT companies, the spokesman replied, "I have just said that we have no right to interfere in this, and the companies decide themselves what corporate governance model to use."
At the same time, the Kremlin is monitoring what is happening with Yandex because of the importance of the company in its sector and the role it can play in the Russian economy, Peskov said.
Yandex said Monday it was setting up a new structure, a Public Interest Foundation (PIF), which will take control of a "golden share" currently held by Sberbank.
PIF is expected to be able to weigh in on consolidation of more than 10 percent of shares in one hands and on some other matters. PIF will be able to nominate two out of 12 members of the Yandex board. The change to the Yandex governance structure has to be approved at an extraordinary meeting of shareholders on December 20.

Field¶
An object that signifies as data field in the query statement.
Creating a new Instance¶
The constructor accepts 2 parameters, a Name and a Type.
By literal string:
1 | var field = new Field(nameof(Customer.Id));
|
Or
1 | var field = new Field(nameof(Customer.Id), typeof(int));
|
The library uses the Type parameter to be resolved when any of the operation is being called.
AsEnumerable¶
Converts an instance of Field object into an IEnumerable<Field> object.
1 2 3 4 5 | // Initialize a field
var field = new Field(nameof(Customer.Id));
// Convert to enumerable
var fields = field.AsEnumerable();
|
From¶
Is used to parse an array of strings and convert it back as an enumerable.
By literal strings:
1 | var fields = Field.From("Id", "Name");
|
By class property:
1 | var fields = Field.From(nameof(Customer.Id), nameof(Customer.Name));
|
Note: When using this method, the Type parameter is not being set. The library will then not set the DbType value of the DbCommand object. By default, ADO.NET uses the DbType.String value.
Parse Type¶
Is used to parse a .NET CLR type and convert it back as an enumerable.
1 | var fields = Field.Parse(typeof(Customer));
|
Parse Entity¶
Is used to parse an entity type and convert it back as an enumerable.
1 | var fields = Field.Parse<Customer>();
|
Parse Object¶
Is used to parse an object and convert it back as an enumerable.
1 2 | var customer = new Customer();
var fields = Field.Parse(customer);
|
Parse Expression¶
Is used to parse an expression and convert it back as an enumerable.
1 | var fields = Field.Parse<Customer>(e => e.Id).AsEnumerable();
|
Usage of Field¶
The field object is mostly used as a queryable fields and qualifiers at some operations.
Being the fields in the Query operation via table name:
1 2 3 4 | using (var connection = new SqlConnection>(@"Server=.;Database=Northwind;Integrated Security=SSPI;").EnsureOpen())
{
var orders = connection.Query("Order", Field.From("Id", "CustomerId", "ProductId"));
}
|
Being the qualifers in the Merge operation:
1 2 3 4 5 6 7 8 9 10 11 12 | using (var connection = new SqlConnection>(@"Server=.;Database=Northwind;Integrated Security=SSPI;").EnsureOpen())
{
connection.Merge<Order>(new Order
{
Id = 1002,
CustomerId = 10045,
ProductId = 12,
Quantity = 5,
LastUpdatedUtc = DateTime.UtcNow
},
qualifiers: Field.From("CustomerId", "ProductId"));
}
|
Being the target fields and qualifers in the MergeAll operation via table name:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | using (var connection = new SqlConnection>(@"Server=.;Database=Northwind;Integrated Security=SSPI;").EnsureOpen())
{
var entities = new[]
{
new
{
Id = 1002,
CustomerId = 10045,
ProductId = 12,
Quantity = 5,
LastUpdatedUtc = DateTime.UtcNow
},
new
{
Id = 1003,
CustomerId = 10224,
ProductId = 19,
Quantity = 2,
LastUpdatedUtc = DateTime.UtcNow
}
};
connection.MergeAll(tableName: "Order",
entities: entities,
qualifiers: Field.From("Id"),
fields: Field.From("CustomerId", "ProductId", "Quantity", "LastUpdatedUtc"));
}
|
Also, being the target fields and qualifers in the UpdateAll operation via table name:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | using (var connection = new SqlConnection>(@"Server=.;Database=Northwind;Integrated Security=SSPI;").EnsureOpen())
{
var entities = new[]
{
new
{
Id = 1002,

J. R. R. Tolkien
From the age of four, J. R. R. Tolkien grew up by the fields and mill at Sarehole, a village now absorbed into Birmingham’s suburbs, from which he took inspiration for ‘The Shire’ (The Hobbit). Perrott’s Folly and the Waterworks Tower in Edgbaston, as well as Old Joe, the University of Birmingham’s clock tower, were his sources of inspiration for the tower of Orthanc, the black tower of Isengard (The Lord of the Rings).
Green Oasis
With 571 parks, Birmingham is one of the UK’s greenest cities. Sutton Park, 6 miles north of the city centre, is one of the largest urban parks in Europe and is designated as a National Nature Reserve and a Site of Special Scientific Interest.
The Lunar Society
In the 18th century, Birmingham paid homage to the richest man in the world back then: Matthew Boulton. Boulton was the manufacturer and engineer who financed and introduced James Watt’s steam engine. He built the Soho manufactory near Birmingham and lived in the elegant Soho House where he hosted meetings of the Lunar Society.
Venice of the North
With nearly 35 miles of canals, Birmingham has more canals than Venice!
Heavy Metal
Birmingham is the birthplace of heavy metal bands Back Sabbath and Judas Priest. Black Sabbath was formed in 1968 by Tony Iommi, Geezer Butler, Bill Ward and Ozzy Osbourne –they played their last concert in the city that saw them rise in February 2017. Judas Priest was formed in 1969 in industrial West Bromwich, 10km west of Birmingham. After many band member replacements, they are still rocking!
Cinema
In the Southside district of Birmingham one can find the UK’s oldest working cinema: the Electric. Nowadays the cinema has two digital screens and shows a mixture of the latest quality mainstream, independent, foreign and classic films.

Connacht Overcome Nightmare Start To Pull Off Brilliant Win Against Montpellier
by PJ BrowneConnacht overcame several injuries and the concession of a try after 70 seconds against Montpellier to claim a brilliant home win in their opening Champions Cup game of the season.
Prior to the match, it was announced that Jarrad Butler, Matt Healy and Niyi Adeolokun had all picked up injuries and would be replaced in the starting lineup.
Those blows were compounded even further when Aaron Cruden touched down in the second minute of the game. It was a nightmare start for Connacht.
The Top 14 team maintained a seven-point advantage for much of the half. However, with three minutes left in the opening 40, Connacht hit back with two quickfire tries.
The first came from backrow Peter Boyle and the second hooker Tom McCartney and meant they led 13-10 at the break.
Connacht extended their lead even further after 12 minutes of the second half when scrum-half Caolin Blade made a burst to score his team's third try of the game.
However, Montpellier hit back ten minutes later through a superb run from Anthony Bouthier. The fullback crossed the whitewash and saw his try converted to level the game at 20-20.
With just over 15 minutes to play, out-half Jack Carty was replaced by 22-year-old Conor Fitzgerald. He was on the pitch just two minutes when he kicked what turned out to be the winning score.

The Math module fills in some gaps in the standard Math library.
Corrects floating point errors
UsefulJS.Math.fcorrect(n[, precision])
n
Numberprecision
NumberReturns: Number The input, possibly corrected for floating point error. If the
input is not a finite number, the return will be the result of converting the input to a
number, Number.NaN
in most cases.
Tiny, uncorrected floating point errors can throw up surprising results:
// What's the base 10 logarithm of 1 billion? Math.log(1e9) / Math.LN10 // 8.999999999999998; almost // What's the tangent of 45 degrees? Math.tan(Math.PI / 4) // 0.9999999999999999; so close // What's the sum of 0.1 and 0.2 0.1 + 0.2 // 0.30000000000000004; really?
fcorrect
calculates the relative error of its input compared to the result
of rounding it to the specified precision. If this value is < the epsilon value of
the system, it assumes that the input has an error and returns the rounded value:
var cFn = UsefulJS.Math.fcorrect; cFn(Math.log(1e9) / Math.LN10) // 9 cFn(Math.tan(Math.PI / 4)) // 1 cFn(0.1 + 0.2, 1) // 0.3; note the precision value
You don't have to wrap all your calculations in fcorrect
, but if you see
some silly results in your output, this method may make them sensible.
Calculates logarithms to any base, not just Math.E
.
UsefulJS.Math.logn(n, base)
n
Numberbase
NumberReturns: Number The logarithm to the specified base.
Throws: RangeError when base is < 0 or not finite.
Silly inputs tend to produce silly results. If n
is 0, the result will generally
be negative infinity. If base
is 1 the result will generally be positive infinity.
If n
is < 0, the result is NaN.
Converts an angle in radians to degrees
UsefulJS.Math.deg(theta)
theta
NumberReturns Number A value in degrees (may be fractional)
Throws: TypeError when theta
is not a finite value.
The Math trigonometric functions work in radians; humans tend to think in terms of degrees. Conversion between the two is straightforward but tedious. Given the growing popularity of game programming, one wonders why angle conversion is not part of the standard library.
UsefulJS.Math.deg(Math.PI / 4); // 45
Converts an angle in radians to degrees, minutes and seconds
UsefulJS.Math.dms(theta)
theta
NumberReturns Array A triplet: degrees, minutes, seconds
Throws: TypeError when theta
is not a finite value.
UsefulJS.Math.dms(1); // [57,17,44.80624709636322]
Converts an angle in degrees (and possibly minutes and seconds) to radians.
UsefulJS.Math.rad(degrees[, minutes, seconds])
degrees
Numberminutes
Numberseconds
NumberReturns Number A value in radians
Throws: TypeError when one or more of the arguments are not finite.
rad
may take one, two or three arguments.
UsefulJS.Math.fcorrect(UsefulJS.Math.rad(57, 17, 44.8062470964)); // 1 // Construct a lookup table of sines from 0 to 360 degrees var sines = (new Array(361)).join('-').split('-').map(function(item, i) { return Math.sin(UsefulJS.Math.rad(i)); });
The fixes for the UsefulJS.Math module are defined in the _math namespace of the input and
output properties of the fix
call. All are applied by default. The property names
are the method names: "sinh", "hypot", "expm1", etc.
expm1
function to calculate ex - 1 (or a dedicated
log1p
function to calculate log(x + 1)), the reason is avoidance
of catastrophic loss of precision for small values of x. For small values of x,
ex and 1 + x are very close to 1. Because of the nature of the floating
point representation of numbers, values closer to 1 than the epsilon value are
indistinguishable from 1 while values closer to 0 than the epsilon value remain
distinguishable from 0. Math.expm1(1e-16)
and Math.log1p(1e-16)
should both return 10-16 while Math.exp(1e-16) - 1
and
Math.log(1 + 1e-16)
will both return 0, a 100% loss of accuracy.Math.acosh(v)

Signed and Unsigned Infinities#
The unsigned infinity “ring” is the set of two elements
infinity
A number less than infinity
The rules for arithmetic are that the unsigned infinity ring does not canonically coerce to any other ring, and all other rings canonically coerce to the unsigned infinity ring, sending all elements to the single element “a number less than infinity” of the unsigned infinity ring. Arithmetic and comparisons then take place in the unsigned infinity ring, where all arithmetic operations that are well-defined are defined.
The infinity “ring” is the set of five elements
plus infinity
a positive finite element
zero
a negative finite element
negative infinity
The infinity ring coerces to the unsigned infinity ring, sending the infinite elements to infinity and the non-infinite elements to “a number less than infinity.” Any ordered ring coerces to the infinity ring in the obvious way.
Note
The shorthand oo
is predefined in Sage to be the same as
+Infinity
in the infinity ring. It is considered equal to, but not
the same as Infinity
in the
UnsignedInfinityRing
.
EXAMPLES:
We fetch the unsigned infinity ring and create some elements:
sage: P = UnsignedInfinityRing; P
The Unsigned Infinity Ring
sage: P(5)
A number less than infinity
sage: P.ngens()
1
sage: unsigned_oo = P.0; unsigned_oo
Infinity
We compare finite numbers with infinity:
sage: 5 < unsigned_oo
True
sage: 5 > unsigned_oo
False
sage: unsigned_oo < 5
False
sage: unsigned_oo > 5
True
Demonstrating the shorthand oo
versus Infinity
:
sage: oo
+Infinity
sage: oo is InfinityRing.0
True
sage: oo is UnsignedInfinityRing.0
False
sage: oo == UnsignedInfinityRing.0
True
We do arithmetic:
sage: unsigned_oo + 5
Infinity
We make 1 / unsigned_oo
return the integer 0 so that arithmetic of
the following type works:
sage: (1/unsigned_oo) + 2
2
sage: 32/5 - (2.439/unsigned_oo)
32/5
Note that many operations are not defined, since the result is not well-defined:
sage: unsigned_oo/0
Traceback (most recent call last):
...
ValueError: quotient of number < oo by number < oo not defined
What happened above is that 0 is canonically coerced to “A number less than infinity” in the unsigned infinity ring. Next, Sage tries to divide by multiplying with its inverse. Finally, this inverse is not well-defined.
sage: 0/unsigned_oo
0
sage: unsigned_oo * 0
Traceback (most recent call last):
...
ValueError: unsigned oo times smaller number not defined
sage: unsigned_oo/unsigned_oo
Traceback (most recent call last):
...
ValueError: unsigned oo times smaller number not defined
In the infinity ring, we can negate infinity, multiply positive numbers by infinity, etc.
sage: P = InfinityRing; P
The Infinity Ring
sage: P(5)
A positive finite number
The symbol oo
is predefined as a shorthand for +Infinity
:
sage: oo
+Infinity
We compare finite and infinite elements:
sage: 5 < oo
True
sage: P(-5) < P(5)
True
sage: P(2) < P(3)
False
sage: -oo < oo
True
We can do more arithmetic than in the unsigned infinity ring:
sage: 2 * oo
+Infinity
sage: -2 * oo
-Infinity
sage: 1 - oo
-Infinity
sage: 1 / oo
0
sage: -1 / oo
0
We make 1 / oo
and 1 / -oo
return the integer 0 instead of the
infinity ring Zero so that arithmetic of the following type works:
sage: (1/oo) + 2
2
sage: 32/5 - (2.439/-oo)
32/5
If we try to subtract infinities or multiply infinity by zero we still get an error:
sage: oo - oo
Traceback (most recent call last):
...
SignError: cannot add infinity to minus infinity
sage: 0 * oo
Traceback (most recent call last):
...
SignError: cannot multiply infinity by zero
sage: P(2) + P(-3)
Traceback (most recent call last):
...
SignError: cannot add positive finite value to negative finite value
Signed infinity can also be represented by RR / RDF elements. But unsigned infinity cannot:
sage: oo in RR, oo in RDF
(True, True)
sage: unsigned_infinity in RR, unsigned_infinity in RDF
(False, False)

OUTPUT:
An assertion error is raised if the representation is not consistent with the infinity ring.
Check that github issue #14045 is fixed:

1. Measurements
First we need to know how big a ping pong ball and a school bus are.
2. Arrangement
Next, we need to determine how the ping pong balls will be arranged to fit to maximize volume.  Each side looks like this.
3. Trigonometry
With a little bit of math, we can determine the length of a side of this cube.
4. Divy up the Space
Now we imagine a school bus as a rectangular prism, and for convenience two of its dimensions are roughly 1 meter.
5. Calculate our Cubes
If we take our two same-sized dimensions of the prism to be made up of 12 cubes each, we can divide the volume by those two lengths, and determine how long the other side should be, which in our case is 68.6 meters. Dividing this by the length of a cube, we can now find the number of cubes that can fit along our third side.
6. Tally up the Numbers
Now that we know how many of our packed cubes can fit into our prism, we can do some quick calculations to figure out the number of balls!
7. Precision/Accuracy
If my calculations are precise, there is a bit of room leftover at the end: just enough to fit one 12 by 12 row of 4-ball groups.

PureBasic V4.00 (Windows)
The now famous, hyped version 4.00 of PureBasic is here. Just judge by yourself, there
is quite a lot of new and sexy looking features. And there is quite a lot of changes as well,
as we took the opportunity to fix long time standing issues by reworking a bit the commandset,
all for the best. Don't be affraid, it can look a bit massive, but you will still feel at home
as absolutely nothing changed about the programming logic. To consult the changes done to the
libraries, click
here. Enjoy !
- Added: Native unicode support
- Added: Subsystems support

- Added: multiple 'Case' for Select/EndSelect: Case 1, 2, 6 To 20
- Added: 'Prototype' keyword to declare functions pointers easily
- Added: 'ProcedureC' keyword to declare cdecl procedure easily
- Added: Procedure parameters can now have the same name than a global variable
(automatically protected)
- Added: EnableExplicit/DisableExplicit: variables must be declared with Define, Global, Protected, Shared
or Static.
- Added: Defined(Name, Type) compiler function. Type can be #PB_Constant, #PB_Variable, #PB_Array,
#PB_LinkedList, #PB_Structure, #PB_Interface
- Added: ReDim for single and multi-dimensionned arrays
- Added: Import/ImportC/EndImport to import functions and variables from external .lib

Macau GT World Cup: Marciello's Mercedes resists Bamber's Porsche
by Andrew van LeeuwenMercedes driver Raffaele Marciello held off Earl Bamber's Porsche to win the qualification race for the 2019 FIA GT World Cup in Macau.
The 12-lap race got off to a wild start with Dries Vanthoor firing his Audi into the wall at Mandarin as he tried to get a run on the polesitting Mercedes.
The Audi driver's race was effectively done on the spot, and Maro Engel was lucky to avoid a similar fate as he brushed the same wall while squabbling over fourth with Edoardo Mortara.
Watch the FIA GT World Cup final from Macau - and the F3 and Motorcycle GPs and WTCR races - live on Autosport this weekend
With Vanthoor out of the picture, Marciello spent the first lap with the two Rowe Porsches, Bamber leading Laurens Vanthoor, breathing down his neck.
But a reprieve quickly arrived, when the safety car was called to clear the stricken Audi from Lisboa.
The race went green again three laps later, but only briefly.
As the field filed into the Lisboa braking area Engel couldn't pull up his Mercedes, clipping Kelvin van der Linde's Audi before clattering into the back of an unsuspecting Mortara.
The clean-up lasted until lap eight, setting up a four-lap battle between Marciello and Bamber.
But while the Kiwi was able to shadow the GruppeM Mercedes there was no way past and Bamber was forced to settle for second with Vanthoor in third.
Defending GT World Cup winner Augusto Farfus finished a fine fourth, coming all the way from 12th on the grid.
The BMW driver was shuffled up the order as Vanthoor, Mortara, Engel and van der Linde had their issues, ending up fifth for the second restart.
Farfus then executed a textbook move on Christopher Haase into Lisboa as the race went green.
Haase finished sixth ahead of Alexandre Imperatori, with Charles Weerts seventh, Kevin Estre eighth, Joel Eriksson ninth and Adderly Fong 10th.
Van der Linde was classified 13th, with repairs after the Engel incident having put him seven laps down.

Mexicans have a rich history with the United States and are among one of the oldest groups of people to live in the United States. Mexicans are the largest ethnic group of Spanish speaking descent that make up the United States and they also make up most of the people living in the United States. When Mexicans began migrating to the United States, many of them typically found themselves working in the farming and ranching industry. When the railroad industry was booming, this industry also gave Mexicans an opportunity to find work at a low-cost wage. While working in the railroad industry, many Mexicans viewed the railroad industry as an opportunity to move their families to different parts of the United States. Many moved to the urban cities in the North and East of the United States. During World War 2, the United States created the Bracero Program, a program that brought over Mexican Laborers to help the shortage of American workers that went off to war.
