Jonathan Adamczewski: What’s the difference between 0xffffffff and 0xffffffffu?

Tue, 2015-02-03 09:27

In C++, what is the difference between 0xffffffff and 0xffffffffu?

This one’s pretty easy to answer with this information from the C++ standard:

The type of an integer literal is the first of the corresponding list in Table 6 in which its value can be represented.

0xffffffff is a hexadecimal constant, it’s too big to be represented in a (signed) int, so — by the terms of the standard — the type of 0xffffffff is unsigned int.

Furthermore, each of these hexadecimal literals will have a different type:

0x7fffffff // int 0xffffffff // unsigned int 0x1ffffffff // long int (or long long int) 0x1ffffffffu // unsigned long int (or unsigned long long int)

But to answer the original question, there is no difference between 0xffffffff and 0xffffffffu apart from this:

@twoscomplement One is a commonly used curse when the compiler screws up.

Stewart Smith: Building OpenPower firmware for use in POWER8 Simulator

Tue, 2015-02-03 09:27

Previously, I blogged on how to Run skiboot (OPAL) on the POWER8 Simulator. If you want to build the full Open Power firmware environment, including the Petitboot bootloader and kernel, you can now do so!

My pull request for an op-build target for the simulator has been merged, so you can now do the following three steps to compile a kernel+initramfs to use with your built skiboot for development purposes:

git clone --recursive git@github.com:open-power/op-build.git cd op-build . op-build-env op-build mambo_defconfig && op-build

Then you wait for a whole bunch of time while everything compiles! Afterwards, you should be left with a zImage.epapr in output/images/ that you can copy into your skiboot directory.

With zImage.epapr in your skiboot directory, when you run “make check”, the skiboot test suite will actually launch the simulator to verify that your skiboot code boots all the way to the petitboot prompt!

We now have two boot tests as part of “make check” for skiboot!

Michael Still: Big Monks

Mon, 2015-02-02 15:28
I'm going to be honest here and say I got this one pretty wrong. Looking at Google Earth, Big Monks is about 1.7 km from the access road (which I got right), what I failed to notice is that it is super steep and that much of the walk is off the trail. So... A walk I thought would take 30 or 45 minutes took 2 hours. I didn't die though, so that's good.



Fantastic views at the top, and found a couple of geocaches. There is obviously a lot of walking potential in Rob Roy Nature Park.



             



Interactive map for this route.

Jonathan Adamczewski: Standards vs Compilers: Warning C4146

Mon, 2015-02-02 09:27

warning C4146: unary minus operator applied to unsigned type, result still unsigned

I saw this warning recently.

“Aha!” I thought. “A common source of errors, able to strike down the unsuspecting programmer. Thank you crafters of Visual C++ compiler warnings, tirelessly laboring to uncover wrong assumptions and naively written code.”

“What?” I exclaimed. “Of course the result is still unsigned. That’s how the language is designed, and that’s what I wanted!”

Nevertheless, I read the documentation for the warning to see if there was anything I could glean from it — particularly to see if I could find sufficient reason to not just #pragma disable it.

This is what you can find in the documentation:

Unsigned types can hold only non-negative values, so unary minus (negation) does not usually make sense when applied to an unsigned type. Both the operand and the result are non-negative.

Negation of an unsigned value may not make sense if you don’t know what it means — it is well defined. Regardless, this is a level 2 warning. It is designed to catch common mistakes and misunderstandings and notify the programmer to have them look more closely. It may be an entirely reasonable thing to warn about.

The documentation continues with some rationale:

Practically, this occurs when the programmer is trying to express the minimum integer value, which is -2147483648. This value cannot be written as -2147483648 because the expression is processed in two stages:

  1. The number 2147483648 is evaluated. Because it is greater than the maximum integer value of 2147483647, the type of 2147483648 is not int, but unsigned int.
  2. Unary minus is applied to the value, with an unsigned result, which also happens to be 2147483648.

The first point is wrong. Wrong for a standards-conformant C++ implementation, anyway. The second would be accurate if the first was accurate (because 232 - 231 == 231)

Here’s what the most recent draft of the C++ standard says about the integer literal types:

The type of an integer literal is the first of the corresponding list in Table 6 in which its value can be represented.

2147483648 is a decimal constant with no suffix. When using VC++ with it’s 32 bit long int type, the first of the corresponding list in which its value can be represented is the 64 bit long long int. An unsigned type is never an option.

Unary minus should then be applied to long long int 2147483648, which should result in long long int -2147483648. There’s nothing unsigned in this process

Use of the result should behave in an unsurprising way, too — long long int -2147483648 can be assigned to a variable of type int and nothing unexpected will happen. The type can be converted without affecting the value.

According to the standard, the rationale is flawed, and the warning seems pointless to me.

In theory, there’s no difference between theory and practise

So I tried compiling the example program from the documentation to see what would happen.

// C4146.cpp // compile with: /W2 #include <stdio.h> void check(int i) { if (i > -2147483648) // C4146 printf_s("%d is greater than the most negative int\n", i); } int main() { check(-100); check(1); }

The documentation predicts the following outcome:

The expected second line, 1 is greater than the most negative int, is not printed because ((unsigned int)1) > 2147483648 is false.

If I build the program with gcc 4.9.2, both lines print.

If I build the program with Visual C++ 2012, or even 2015 Preview, only one line is printed (as was predicted).

So there is legitimacy to this warning — this is an area that Visual C++ is not compliant with the standard.

Maybe it’s because the standard has changed? I looked at the earliest version of the text available in the cplusplus github repo dating from late 2011, and that has the same rules as quoted above.

I went back further and found copies of the standard from 2003 and 1998, both of which state:

The type of an integer literal depends on its form, value, and suffix. If it is decimal and has no suffix, it has the first of these types in which its value can be represented: int, long int; if the value cannot be represented as a long int, the behavior is undefined.

So it’s a detail that was previously undefined, which means that the compiler is permitted to do whatever it wants. In this case, we’ll get a warning, but only if the programmer has asked for it using option /W2.

The documentation is accurate, and Visual C++ hasn’t kept up with changes in the standard. This shouldn’t be surprising.

Update: long long int was added to the standard as part of C++11. It appears that VC++ has had long long support since at least Visual Studio .NET 2003

So what?

This investigation arose from my reading of Visual C++ documentation in the context of what I knew of a recent draft of the C++ standard. It turns out that these two things are less connected than I had assumed. Unsurprisingly, the Visual C++ documentation describes Visual C++, not the standard.

While it would be nice if deviations from the standard were clearly marked in the documentation, and even nicer if the Visual C++ compiler was consistent with the ISO standard, the reality is that they are not and it is not.

One should always pay close attention to context, which happens to apply as much when reading about the C++ language as it does when writing C++ code.

Colin Charles: MariaDB turns 5!

Mon, 2015-02-02 00:25

I stopped working on MySQL at Sun Microsystems in late 2009 (after a lengthy period of garden leave), to join Monty Program Ab, and was greatly anticipating a MariaDB release that we could take to market. The first GA release of MariaDB came out February 1 2010 – MariaDB 5.1.42. Today is MariaDB Server’s 5th birthday!

We didn’t even want to call it GA back then — we referred to it as a “stable” release. We didn’t make our own builds because we figured source code tarballs were good enough; so builds were made and hosted at OurDelta. It took some months (around August 2010) when we moved release notes to the Knowledgebase (which you’ll notice has moved from kb.askmonty.org to its current location) from the old front page wiki install that we had at askmonty.org.

I didn’t go to the first company meeting in Malaga due to having the chickenpox, so my first meeting was the one we did in Reykjavik, Iceland. We did it towards the end of February 2010, and planned it literally in a month – maybe a celebration that we brought 5.1 to market on time, and also to plan 5.2.

Speaking of companies, we were Monty Program Ab (professionally this quickly became MariaDB Services Ab), then SkySQL Ab (via merger), and finally MariaDB Corporation Ab (via re-branding). Shortly before the SkySQL Ab merger, we even have the MariaDB Foundation appear.

Anyway, what have we released? MariaDB 5.1, MariaDB 5.2, MariaDB 5.3, MariaDB 5.5, MariaDB 10.0, MariaDB Galera Cluster 5.5 & 10.0, a special MariaDB 5.5 with TokuDB build and a special MariaDB with FusionIO improvements build. To boot, we also have three client libraries (connectors, if you must): C, Java, and ODBC.

So 5 major server releases (7 if you count the Galera series), and we’re now working on MariaDB 10.1. I count 88 releases of the server across various versions (with breakdowns: 9 alphas, 11 betas, 7 release candidates and 61 GAs). We’ve had 23 Galera releases and 15 releases for the various client libraries.

We are shipping in all major Linux and BSD distributions. In many, we are even the default

This birthday is a nice time to look back at our achievements, but also to remind ourselves to not rest on our laurels and continue to focus on growth. The last sanctioned press release talks of over 2 million users globally. 

Thank you to all our users. Thank you to all the contributors and developers. Here’s to a lot more adoption, growth, releases and technology improvements!

Came across one of these during the week. I looked at it, did a bit more research though and found out that the battery was dying, that the company was in trouble, and that no spare parts were being manufactured which meant that you would have to retrofit your own battery from another source if it came down to it (I found out that a HTC ChaCha battery actually fits the physical dimensions required and actually has the characteristics to get the job done. Since, I don't like risking the possiblity of overheating I decided to pass on the purchase. I obviously thought about the chance of fitting an iPod battery in there as well which explains the links... Not enough information available online though regarding physical dimensions.

Have been doing more research on understanding the concept of 'layering' in song composition. The consensus seems to be that in electronic music (anything that features heavily synthesised sounds), you basically start from percussion/a drumline and then you work your way upwards, adding synths, basses, and so on (you can start the other way around to but if you have sufficient knowledge of percussion but it doesn't quite have that some feeling/sensation to it). You may even start with a pattern of single notes to create a melody and then base your lyrics around that based on what I've read. For this particular reason, I've been looking more into percussion and patterns that are peculiar to each particular (keywords "percussion music pdf" in Google). Some really interesing stuff. I didn't realise that notation in percussion could be 'customised' because there were so many different instruments that were possibly available?

Obviously, once you have a percussion part that is suitable to he genre of music you can begin to layer up. For instance, think about common elements/instruments/sounds. Layer based on genre, thinking about what you have, what you can adjust, what you can find, what you can create or imagine whether it is via software or hardware... One thing you should know, writing songs isn't really an incremental process. It's like some other things I've experienced in life. Once you hit a plateau and begin to understand the next step, you gain a whole bunch of extra bits and pieces. While you were previously only able to write half a song, now you can write three-quarters of it, or you suddently discover a way to take your sound quality to a completely new level.

You listen to enough music (out on the Internet, at concerts/bars/out on the streets, purchasing from retail, etc...) and you basically get the impression that a lot of what is released out there isn't actually all that great (the supposed idea behind the Apple Music Store) which is a good thing and a bad thing. Think in terms of marketing. You name a genre, there is likely a website that is dedicated to that particular style of music. Here's the problem though. Remember the premise of the Apple Music Store. Out of every album you purchase you're only going to like anywhere between one and a maximum of four songs on it (average based on my collection and personal experience). Factor in the fact that the barrier to entry for online music is much lower and you basically have very little chance of making it unless you can churn out consistently good music or else you create the 'song of your life' at some point along the line because that is basically what it will take to rise above the rabble.



The irony is this. By reading, taking courses, and so on... you end up with a baseline knowledge of how to compose but it also means that you may end up with some very formulaic songs. Watch for DJ's, producers, composers, engineers, etc... Just like a person's character there tend to be idiosyncracies in the sound that they produce (whether that may be down to preference, talent, equipment, etc...).

- In the realm of law, the RSS wants the passage of a stringent nationwide bill that would ban religious conversions. In the public sphere, it has arrogated the right to pronounce not just on the future of minorities in India but that of India's Hindu majority as well. In the war of the religions, it seeks to spread the news that there is now a Hindu fundamentalism eager to goad and trump well-established Christian and Islamic fundamentals in India and around the world. And among its own vast cadre, it has generated the sense that it, much more than the government of the day or the diverse institutions of civil society and business, holds the key to India's future.

...

As a Hindu, I have some sympathy with this viewpoint. Missionary activity has always seemed to me unacceptably crude and arrogant, not only in its conviction that there is a single truth that must be propagated, but also in its contempt for two of the forces that most strongly influence religious belief: The accident of birth in a certain religion, which is then followed by many years of socialisation into its worldview.http://gulfnews.com/opinions/columnists/a-new-vision-of-india-that-is-100-hindu-1.1433102

Hindu fundamentalists, saying Christian missionaries and Muslim conquerors converted Indians by force centuries ago, have for years quietly sought to win them back. This year, seemingly invigorated by the rise of a right-wing Hindu government in New Delhi, they have organised mass reconversion "camps", including some where people have alleged they were duped or threatened into changing faiths.

A solemn and dignified Ramadan indeed. Sometimes it takes a clown to speak the truths that others won't face.

- Yun's quest - a modern version of the age old dream of tapping the fountain of youth - is emblematic of the current enthusiasm to disrupt death sweeping Silicon Valley. Billionaires and companies are bullish about what they can achieve. In September 2013 Google announced the creation of Calico, short for the California Life Company. Its mission is to reverse engineer the biology that controls lifespan and "devise interventions that enable people to lead longer and healthier lives". Though much mystery surrounds the new biotech company, it seems to be looking in part to develop age-defying drugs. In April 2014 it recruited Cynthia Kenyon, a scientist acclaimed for work that included genetically engineering roundworms to live up to six times longer than normal, and who has spoken of dreaming of applying her discoveries to people. "Calico has the money to do almost anything it wants," says Tom Johnson, an earlier pioneer of the field now at the University of Colorado who was the first to find a genetic effect on longevity in a worm.

- But let's remember that central bank quantitative easing (QE) of the kind that Europe is now embarking on is always just a Band-Aid on economic troubles, not a solution to underlying structural issues in a country (or in this case, a region). Just as the Fed's $4 trillion QE money dump bolstered the markets but didn't fix the core problems in our economy--growing inequality, a high/low job market without enough work in the middle, flat wages, historically low workforce participation--so the ECB QE will excite markets for a while, but it won't mend the problems that led Europe to need this program to begin with.

Marco Rubio, R-Florida -- a prospective 2016 presidential candidate -- suggested recently on CBS' Face the Nation. "What we need to do is create competition with alternative methods where people can acquire certification programs that take less than two years, and get you to work right away as a welder, electrician, and airplane mechanic. I wish he would spend more time on that, and less time trying to raise taxes and pour money into an outdated model that no longer works in the 21st Century."

- The test was anything but scientific - it says as much about my proficiency with the different input methods as it does about the input methods themselves - but the results were interesting and not at all what I expected. Swype, the keyboard you use by drawing lines over the letters without lifting your finger, was by far the slowest for me, due to the fact it coped very poorly indeed with longer, not-so-common words in the text. Next slowest was the handwriting recognition on Samsung's Galaxy Note 4, using its stylus, due to the fact it kept capitalising words that shouldn't be capitalised. I really thought it would be one of the faster ones. Then came the stock Android keyboard, then second fastest was the keyboard on the iPhone, thanks to its uncanny auto-correction ability that lets you type at an insane pace and still have near perfect accuracy.



But fastest of all by some margin, twice as fast as Swype and 30 per cent faster than the iPhone, was the keyboard on the Classic. Not only that, but it was the only input device that allowed me to take my eyes off the keyboard and look at the stopwatch while entering text. It's so easy to use, and so fast.

- In this day and age confidence is king. You can embark on all of the education you like but if you can't back yourself, or make it clear to others that you're up for the fight then others will pass you by. Nick Kyrgios is definitely letting everyone know he's not holding back, and he's having one hell of a crack.

Some are saying Nick is one of the most exciting sporting prospects Australia has seen in a long while, so lets not cook the golden goose, instead let it run wild, and who knows what will eventuate.

- The most successful companies need a vision, and both Apple and Microsoft have one. But Apple's was more radical and, as it turns out, more farsighted. Microsoft foresaw a computer on every person's desk, a radical idea when IBM mainframes took up entire rooms. But Apple went a big step further: Its vision was a computer in every pocket. That computer also just happened to be a phone, the most ubiquitous consumer device in the world. Apple ended up disrupting two huge markets.

...

Mr. Cihra noted that Microsoft already dominates its core businesses, leaving little room for growth. But, he said, "Apple still doesn't have massive market share in any of its core markets. Even in smartphones, its share is only in the midteens. Apple's strategy has been to carve out a small share of a massive market. It's pretty much a unique model that leaves plenty of room for growth."

- The new administration said the sackings of the heads of the Hellenic Republic Asset Development Fund will put an end to "close-out sale" privatisation policies, Greek media reported. From now on, privatisations will take place when they create new jobs and generate economic growth, the government said.



Privatisations of state companies are an important part of a reform program the previous government agreed to with its international creditors in return for a EUR240 billion ($350 billion) bailout. Interest from investors for the state offerings, however, has been low, and the revenues from the sales have come in sharply below expectations.

...

"The wind of change is starting to blow in Europe," party leader Pablo Iglesias, a 36-year-old former university professor, said in Greek and Spanish as he addressed supporters. "We dream but we take our dream seriously. More has been done in Greece in six days than many governments did in years."

Born out of the "Indignants" protest movement that filled Spanish squares in 2011 with demands for change, Podemos says it wants to prevent profitable companies firing workers, promote fully state-controlled healthcare and enact a "significant" minimum-wage hike.

- The team carried out the research using astero-seismology -- listening to the natural resonances of the host star which are caused by sound trapped within it. These oscillations lead to miniscule changes or pulses in its brightness which allow the researchers to measure its diameter, mass and age. The planets were then detected from the dimming that occurs when the planets transited, or passed across, the stellar disc. This fractional fading in the intensity of the light received from the star enables scientists to accurately measure the size of the planets relative to the size of the star.

- In DJ parlance, a break is where all elements of a song (e.g., pads, basslines, vocals), except for percussion, disappear for a time. This is distinguished from a breakdown, a section where the composition is deliberately deconstructed to minimal elements (usually the percussion or rhythm section with the vocal re-introduced over the minimal backing), all other parts having been gradually or suddenly cut out.[1] The distinction between breaks and breakdowns may be described as, "Breaks are for the drummer; breakdowns are for hands in the air".[1]



In hip hop and electronica, a short break is also known as a "cut", and the reintroduction of the full bass line and drums is known as a "drop", which is sometimes accented by cutting off everything, even the percussion.

- Mobile users are increasingly driving traffic to Facebook, and advertisers have responded by purchasing large numbers of mobile ads. More than $1 in every $5 spent on Facebook advertising now goes to mobile, even though mobile ads command a premium cost-per-click rate of $1.38 -- compared to $0.81 for desktop ads. Also of note: The majority of tablet users access Facebook using an Apple product, but when it comes to phones, the Android operating system drives more traffic. -- AllFacebook

http://www.entrepreneur.com/blog/225499- Robotics executives say even though blue-collar jobs will be lost, more efficient manufacturing will create skilled jobs in designing, operating and servicing assembly lines.

A report commissioned by the International Federation of Robotics last year found that 150,000 people are already employed by robotics manufacturers worldwide in engineering and assembly jobs.
