Adding Playgrounds to Xcode Projects

Monday, April 24, 13:04 UTC @ Use Your Loaf

Playgrounds are a great way to try out ideas but I have tended to use them standalone. They also make great companions when added to your Xcode projects. I especially like being able to use the playground live view to preview view and layout code without the need for Interface Builder. Unfortunately a playground does not automatically get access to the code and resources of a project. Getting it all setup the first time is a pain so for future reference here is my step-by-step guide.

Succinct progress measures for solving parity games. (arXiv:1702.05051v2 [cs.DS] CROSS LISTED)

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

The recent breakthrough paper by Calude et al. has given the first algorithm for solving parity games in quasi-polynomial time, where previously the best algorithms were mildly subexponential. We devise an alternative quasi-polynomial time algorithm based on progress measures, which allows us to reduce the space required from quasi-polynomial to nearly linear. Our key technical tools are a novel concept of ordered tree coding, and a succinct tree coding result that we prove using bounded adaptive multi-c

Path-contractions, edge deletions and connectivity preservation. (arXiv:1704.06622v1 [cs.DS])

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

We study several problems related to graph modification problems under connectivity constraints from the perspective of parameterized complexity: {\sc (Weighted) Biconnectivity Deletion}, where we are tasked with deleting~$k$ edges while preserving biconnectivity in an undirected graph, {\sc Vertex-deletion Preserving Strong Connectivity}, where we want to maintain strong connectivity of a digraph while deleting exactly~$k$ vertices, and {\sc Path-contraction Preserving Strong Connectivity}, in which the

The Ising Partition Function: Zeros and Deterministic Approximation. (arXiv:1704.06493v1 [cs.DS])

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

We study the problem of approximating the partition function of the ferromagnetic Ising model in graphs and hypergraphs. Our first result is a deterministic approximation scheme (an FPTAS) for the partition function in bounded degree graphs that is valid over the entire range of parameters $\beta$ (the interaction) and $\lambda$ (the external field), except for the case $\vert{\lambda}\vert=1$ (the "zero-field" case). A randomized algorithm (FPRAS) for all graphs, and all $\beta,\lambda$, has long been k

$k$-Distinct In- and Out-Branchings in Digraphs. (arXiv:1612.03607v2 [cs.DS] UPDATED)

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

An out-branching and an in-branching of a digraph $D$ are called $k$-distinct if each of them has $k$ arcs absent in the other. Bang-Jensen, Saurabh and Simonsen (2016) proved that the problem of deciding whether a strongly connected digraph $D$ has $k$-distinct out-branching and in-branching is fixed-parameter tractable (FPT) when parameterized by $k$. They asked whether the problem remains FPT when extended to arbitrary digraphs. Bang-Jensen and Yeo (2008) asked whether the same problem is FPT when the

Exploring the bounds on the positive semidefinite rank. (arXiv:1704.06507v1 [cs.CC])

Monday, April 24, 01:30 UTC @ cs.CC updates on arXiv.org

The nonnegative and positive semidefinite (PSD-) ranks are closely connected to the nonnegative and positive semidefinite extension complexities of a polytope, which are the minimal dimensions of linear and SDP programs which represent this polytope. Though some exponential lower bounds on the nonnegative and PSD- ranks has recently been proved for the slack matrices of some particular polytopes, there are still no tight bounds for these quantities. We explore some existing bounds on the PSD-rank and pro

Fairness in Resource Allocation and Slowed-down Dependent Rounding. (arXiv:1704.06528v1 [cs.DS])

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

We consider an issue of much current concern: could fairness, an issue that is already difficult to guarantee, worsen when algorithms run much of our lives? We consider this in the context of resource-allocation problems; we show that algorithms can guarantee certain types of fairness in a verifiable way. Our conceptual contribution is a simple approach to fairness in this context, which only requires that all users trust some public lottery. Our technical contributions are in ways to address the $k$-cen

Shared processor scheduling. (arXiv:1704.06361v1 [cs.DM])

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

We study the shared processor scheduling problem with a single shared processor where a unit time saving (weight) obtained by processing a job on the shared processor depends on the job. A polynomial-time optimization algorithm has been given for the problem with equal weights in the literature. This paper extends that result by showing an $O(n \log n)$ optimization algorithm for a class of instances in which non-decreasing order of jobs with respect to processing times provides a non-increasing order wi

Low-complexity Image and Video Coding Based on an Approximate Discrete Tchebichef Transform. (arXiv:1609.07630v2 [cs.MM] UPDATED)

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

The usage of linear transformations has great relevance for data decorrelation applications, like image and video compression. In that sense, the discrete Tchebichef transform (DTT) possesses useful coding and decorrelation properties. The DTT transform kernel does not depend on the input data and fast algorithms can be developed to real time applications. However, the DTT fast algorithm presented in literature possess high computational complexity. In this work, we introduce a new low-complexity approxi

A Time Hierarchy Theorem for the LOCAL Model. (arXiv:1704.06297v1 [cs.DC])

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

The celebrated Time Hierarchy Theorem for Turing machines states, informally, that more problems can be solved given more time. The extent to which a time hierarchy-type theorem holds in the distributed LOCAL model has been open for many years. It is consistent with previous results that all natural problems in the LOCAL model can be classified according to a small constant number of complexities, such as $O(1),O(\log^* n), O(\log n), 2^{O(\sqrt{\log n})}$, etc. In this paper we establish the fir

Quantum Speed-ups for Semidefinite Programming. (arXiv:1609.05537v4 [quant-ph] UPDATED)

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

We give a quantum algorithm for solving semidefinite programs (SDPs). It has worst case running time n^{1/2}m^{1/2}s poly(log(n), log(m), R, r, 1/delta), with n and s the dimension and sparsity of the input matrices, respectively, m the number of constraints, delta the accuracy of the solution, and R, r upper bounds on the size of the optimal primal and dual solutions. This gives a square-root unconditional speed-up over any classical method for solving SDPs both in n and m. We prove the algorithm cannot

Approximation Algorithms for Optimal Decision Trees and Adaptive TSP Problems. (arXiv:1003.0722v3 [cs.DS] UPDATED)

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

We consider the problem of constructing optimal decision trees: given a collection of tests which can disambiguate between a set of $m$ possible diseases, each test having a cost, and the a-priori likelihood of the patient having any particular disease, what is a good adaptive strategy to perform these tests to minimize the expected cost to identify the disease? We settle the approximability of this problem by giving a tight $O(\log m)$-approximation algorithm. We also consider a more substantial general

Extremal eigenvalues of local Hamiltonians. (arXiv:1507.00739v4 [quant-ph] UPDATED)

Monday, April 24, 01:30 UTC @ cs.CC updates on arXiv.org

We apply classical algorithms for approximately solving constraint satisfaction problems to find bounds on extremal eigenvalues of local Hamiltonians. We consider spin Hamiltonians for which we have an upper bound on the number of terms in which each spin participates, and find extensive bounds for the operator norm and ground-state energy of such Hamiltonians under this constraint. In each case the bound is achieved by a product state which can be found efficiently using a classical algorithm.

Maximum Matching in Two, Three, and a Few More Passes Over Graph Streams. (arXiv:1702.02559v3 [cs.DS] UPDATED)

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

We consider the maximum matching problem in the semi-streaming model formalized by Feigenbaum, Kannan, McGregor, Suri, and Zhang that is inspired by giant graphs of today. As our main result, we give a two-pass $(1/2 + 1/16)$-approximation algorithm for triangle-free graphs and a two-pass $(1/2 + 1/32)$-approximation algorithm for general graphs; these improve the approximation ratios of $1/2 + 1/52$ for bipartite graphs and $1/2 + 1/140$ for general graphs by Konrad, Magniez, and Mathieu. In three passe

A Simple Randomized Algorithm to Compute Harmonic Numbers and Logarithms. (arXiv:1704.04538v2 [cs.DS] UPDATED)

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

Given a list of N numbers, the maximum can be computed in N iterations. During these N iterations, the maximum gets updated on average as many times as the Nth harmonic number. We first use this fact to approximate the Nth harmonic number as a side effect. Further, using the fact the Nth harmonic number is equal to the natural logarithm of N plus a constant that goes to zero with N, we approximate the natural logarithm from the harmonic number. To improve accuracy, we repeat the computation over many lis

A complete dichotomy for complex-valued Holant^c. (arXiv:1704.05798v2 [quant-ph] UPDATED)

Monday, April 24, 01:30 UTC @ cs.CC updates on arXiv.org

Holant problems are a family of counting problems on graphs, parametrised by sets of complex-valued functions of Boolean inputs. Holant^c denotes a subfamily of those problems, where any function set considered must contain the two unary functions pinning inputs to values 0 or 1. The complexity classification of Holant problems usually takes the form of dichotomy theorems, showing that for any set of functions in the family, the problem is either #P-hard or it can be solved in polynomial time.

Settling the query complexity of non-adaptive junta testing. (arXiv:1704.06314v1 [cs.CC])

Monday, April 24, 01:30 UTC @ cs.CC updates on arXiv.org

We prove that any non-adaptive algorithm that tests whether an unknown Boolean function $f: \{0, 1\}^n\to \{0, 1\}$ is a $k$-junta or $\epsilon$-far from every $k$-junta must make $\widetilde{\Omega}(k^{3/2} / \epsilon)$ many queries for a wide range of parameters $k$ and $\epsilon$. Our result dramatically improves previous lower bounds from [BGSMdW13, STW15], and is essentially optimal given Blais's non-adaptive junta tester from [Blais08], which makes $\widetilde{O}(k^{3/2})/\epsilon$ queries.

On an almost-universal hash function family with applications to authentication and secrecy codes. (arXiv:1507.02331v4 [cs.CR] UPDATED)

Monday, April 24, 01:30 UTC @ cs.DS updates on arXiv.org

Universal hashing, discovered by Carter and Wegman in 1979, has many important applications in computer science. MMH$^*$, which was shown to be $\Delta$-universal by Halevi and Krawczyk in 1997, is a well-known universal hash function family. We introduce a variant of MMH$^*$, that we call GRDH, where we use an arbitrary integer $n>1$ instead of prime $p$ and let the keys $\mathbf{x}=\langle x_1, \ldots, x_k \rangle \in \mathbb{Z}_n^k$ satisfy the conditions $\gcd(x_i,n)=t_i$ ($1\leq i\leq k$), where

Walt Mossberg on the origins of his Personal Tech column for The Wall Street Journal back in 1991: There were a bunch of computer columns in a lot of other newspapers, and certainly there were computer magazines, but these were all written by geeks for geeks. My pitch to The Journal was that I wanted to write a column that didn’t use a lot of jargon, that treated people with respect for their intelligence and that did two things. One, it helped people figure out how to make this jou

Then the one remaining aces case can be checked with your current method. It's possible that the optional create might be more performat when you're returning Option<u32

★ The Mac Pro Lives

Tuesday, April 04, 12:00 UTC @ Daring Fireball

Apple is currently hard at work on a “completely rethought” Mac Pro, with a modular design that can accommodate high-end CPUs and big honking hot-running GPUs, and which should make it easier for Apple to update with new components on a regular basis. They’re also working on Apple-branded pro displays to go with them. That’s the good news.

Frontier Diary #1: VM Life

Monday, April 03, 20:44 UTC @ inessential.com

It’s been years since I could build the Frontier kernel — but I finally got it building. It’s really a ’90s Mac app that’s been Carbonized just enough to run on MacOS, but it’s by no means modern: it uses QuickDraw and early Carbon APIs. It’s written entirely in C. I got it building by installing MacOS 10.6.8 Server in VMWare. Installed Xcode 3.2.6. And now, finally, I can build and run it. What is Frontier? Frontier

Stack View Background Color

Monday, April 03, 08:35 UTC @ Use Your Loaf

How do you set a background color for a stack view? For that matter how do overlay foreground or other decorator views over a stack view? If you have used UIStackView you probably know that it is not a normal subclass of UIView. Setting its backgroundColor has no effect. What we can do is add subviews that are not managed by the stack view. From the header file for UIStackView: UIStackView is a non-rendering subclas

Analyzing Third Party Libraries

Many of our engineers are embedded with our clients, working along side our client’s engineering staff as one unit — but still representing MartianCraft and the quality and standards of any of our engineers. Which can be a test for an engineer when it comes to the selection of third party code libraries. As a company our default position is: you are better off never using third party libraries. Of course there are always exceptions to such positions, but this is our core belief and because of

Wednesday, March 22, 17:58 UTC @ Backreaction

A week or so ago, a list of perverse incentives in academia made rounds. It offers examples like “rewarding an increased number of citations” that – instead of encouraging work of high quality and impact – results in inflated citation lists, an academic tit-for-tat which has become standard practice. Likewise, rewarding a high number of publications doesn’t produce more good science, but merely

Healthcare research: IBM uncovers new way to stimulate the body to fight disease

Wednesday, March 22, 17:26 UTC @ IBM Blog Research

Using nanomaterials to carry drug molecules to specific cells in the body is a relatively new field in healthcare research. But it’s an important one. For example, in order to target therapies to tumors, scientists have developed techniques to attach drug molecules (or vaccines) to nanomaterials like graphene sheets, a single-atom-thick sheet of carbon that […] The post

The Debugging Mindset

Wednesday, March 22, 13:04 UTC @ ACM Queue - All Queue Content

Software developers spend 35-50 percent of their time validating and debugging software. The cost of debugging, testing, and verification is estimated to account for 50-75 percent of the total budget of software development projects, amounting to more than $100 billion annually. While tools, languages, and environments have reduced the time spent on individual debugging tasks, they have not significantly reduced the total time spent debugging, nor the cost of doing so. Therefore, a hyperfocus on elimination

Variable Height Table View Header

Monday, March 20, 10:36 UTC @ Use Your Loaf

Making a table view header that automatically adjusts its height to allow its contents to fit should not be so hard.

If you want to help your bad students DO NOT give an easy exam

1) When I was a grad student TAing Formal Lang Theory we had a final ready to give out but noticed that one problem was too hard. So we changed it. But we made it too easy. Whoops. My thought at the time was this will help the bad students. I was wrong. Roughly speaking the students who got 70-80 on the midterm now got 90-100 on the final whereas the students who got 30-40 on the midterm got 35-45 on the final. So the bad students improved, but the better students improved more. 2

A star is a widely understood symbol used for ratings. If you’re building a UI for rating in an app, chances are you’ll be using a star in there somewhere. There are many different ways to get a star on the screen in your app, but the best way is to draw it from scratch in code. Not only does this give you total flexibility in terms of size and screen resolution and the ability to create awesome effects using core animation, it also allows you to totally nerd out on geometry.

Tuesday, March 07, 20:09 UTC @ IBM Blog Research

Depending on whom you ask, humans miss one to two words out of every 20 they hear. In a five-minute conversation, that could be as many 80 words. But, for most of us speech recognition isn’t a problem. Imagine, though, how difficult it is for a computer? Last year, IBM announced a major milestone in […] The post IBM achieves new record in speech recognition appeared first on

Pi and the Golden Ratio

Tuesday, March 07, 16:47 UTC @ Azimuth

Two of my favorite numbers are pi: and the golden ratio: They’re related: Greg Egan and I came up with this formula last weekend. It’s probably not new, and it certainly wouldn’t surprise experts, but it’s still fun coming up with a formula like this. Let me explain how we did it. History has a […]

So you want to be like Steve Jobs?

Tuesday, March 07, 13:53 UTC @ Business of Software USA

How many entrepreneurs do you know who model themselves, consciously or unconsciously, on Steve Jobs? By all accounts, Steve Jobs combined incredible genius and an ability to get things done with a personality that could politely be described as ‘difficult’. In fact, many people who worked for him describe him as an asshole. Despite everything, […] The post So you want to be like Steve Jobs?

why are regular expressions defined the way they are

Monday, March 06, 18:01 UTC @ Computational Complexity

BILL: The best way to prove closure properties of regular languages is to first prove the equiv of DFA's, NDFA's and Reg Expressions. Then, if you want to prove a closure property, choose the definition of regular that makes it easiest. For example, to prove Reg Langs closed under intersection I would use DFA's, NOT Reg Expressions. STUDENT: I thought reg expressions were a) finite sets b) if alpha and beta are reg exp then so are alpha UNION beta, alpha INTER

MongoDB's JavaScript Fuzzer

Monday, March 06, 17:07 UTC @ ACM Queue - All Queue Content

As MongoDB becomes more feature-rich and complex with time, the need to develop more sophisticated methods for finding bugs grows as well. Three years ago, MongDB added a home-grown JavaScript fuzzer to its toolkit, and it is now our most prolific bug-finding tool, responsible for detecting almost 200 bugs over the course of two release cycles. These bugs span a range of MongoDB components from sharding to the storage engine, with symptoms ranging from deadlocks to data inconsistency. The fuzzer runs as par

First steps towards programming a quantum computer over the cloud

Monday, March 06, 05:01 UTC @ IBM Blog Research

Since last year, scientists, students, and the quantum computing curious have been able to explore the world’s first and only cloud-enabled quantum computing platform, the IBM Quantum Experience. They’re running well-known canonical quantum algorithms, such as two-qubit Grover’s Search, and even trying their own experiments on our IBM Cloud-hosted five-qubit quantum processor. We designed the […] The post

Nutrition for Remote Workers

Introduction At MartianCraft, remote work is a big part of our lives. We’ve written about challenges of working remotely and we’ve explored the benefits of sharing in family life. For many of us, the step from on-site to remote work comes with a lot of changes, and challenges. One of the most noticeable changes I’ve experienced after I sta

Implicit Swift Dependencies

Friday, March 03, 18:03 UTC @ Indie Stack

If you’re developing in Swift for Mac or iOS, you need to ensure that any standard Swift libraries are also copied into your app bundle. Typically this is handled automatically by Xcode when it detects the presence of any Swift files in your app. If your app is entirely Objective-C, but you link against your … Continue reading Implicit Swift Dependencies

Improving on the Unix shell

Yes, a violation of energy conservation can explain the cosmological constant

Chad Orzel recently pointed me towards an article in Physics World according to which “Dark energy emerges when energy conservation is violated.” Quoted in the Physics World article are George Ellis, who enthusiastically notes that the idea is “no more fanciful than many other ideas being explored in theoretical physics at present,” and Lee Smolin, according to whom it’s “speculative, but in the

How Big Data is Making Scientists Smarter about Ebola

Thursday, March 02, 14:00 UTC @ IBM Blog Research

The 2014 West Africa Ebola outbreak was a tragedy of enormous proportions. It caused the death of over 11,000 people, while more than 28,000 cases have been reported. From a socioeconomic, perspective, it has brought close to collapse the three African countries most directly impacted: Sierra Leone, Liberia, and Guinea. During the outbreak and immediately […] The post Ho

International Science

Thursday, March 02, 13:02 UTC @ Computational Complexity

I did some counting and the 35 academic faculty members in the Georgia Tech School of Computer Science come from 14 different countries. My co-authors come from at least 20 different nations. My 10 successful PhD students hail from 7 different countries. I have benefited immensely from global collaborations thanks to relatively open borders and communication during most of my academic career and I am hardly the only academic who has done so. I'm old enough to remember the days of the cold war w

Composable UIs

Thursday, March 02, 00:00 UTC @ Pedro Piñera

One important aspect that as developers, we should keep in mind, is trying to reuse the code that we write whenever it’s possible. The main reason behind that is saving time. For example, if you write a cell for your app, TrackCell and you need the same (or similar) cell in a different collection view, you should try to reuse the one that you already have. However, sometimes the specifications of that cell change a little bit, and we end up with a bunch o

The slime-selector

Wednesday, March 01, 15:27 UTC @ Zach Beane Common Lisp

I use and love the slime-selector. It’s a very quick way to jump around between various SLIME buffers. In my .emacs, C-c s is bound to slime-selector with (global-set-key "\C-cs" 'slime-selector) Then, in any buffer, I can use \C-c s to pop up a minibuffer selector that takes a single additional key. Here’s the list of keys and what they do: 4: Select in other window ?: Selector help buf

Numerically integrating periodic functions

Wednesday, March 01, 14:40 UTC @ John D. Cook

The trapezoid rule is the most obvious numerical integration technique. It comes directly from the definition of a definite integral, just a Riemann sum. It’s a very crude technique in general; you can get much more accuracy with the same number of function evaluations by using a more sophisticated method. But for smooth periodic functions, […]

Does Anybody Listen to You?

Wednesday, March 01, 10:03 UTC @ ACM Queue - All Queue Content

An idea on its own is not worth much. Just because you think you know a better way to do something, even if you're right, no one is required to care. Making great things happen at work is about more than just being smart. Good ideas succeed or fail depending on your ability to communicate them correctly to the people who have the power to make them happen. When you are navigating an organization, it pays to know whom to talk to and how to reach them. Here is a simple guide to sending your ideas up the chain
