We introduce primal and dual stochastic gradient oracle methods for decentralized convex optimization problems. Both for primal and dual oracles the proposed methods are optimal in terms of the number of communication steps. However, for all classes of the objective, the optimality in terms of the number of oracle calls per node in the class of methods with optimal number of communication steps takes place only up to a logarithmic factor and the notion of smoothness. By using mini-batching technique we show that all proposed methods with stochastic oracle can be additionally parallelized at each node.

This paper develops a method for obtaining guaranteed outer approximations for global attractors of continuous and discrete time nonlinear dynamical systems. The method is based on a hierarchy of semidefinite programming problems of increasing size with guaranteed convergence to the global attractor. The approach taken follows an established line of reasoning, where we first characterize the global attractor via an infinite dimensional linear programming problem (LP) in the space of Borel measures. The dual to this LP is in the space of continuous functions and its feasible solutions provide guaranteed outer approximations to the global attractor. For systems with polynomial dynamics, a hierarchy of finite-dimensional sum-of-squares tightenings of the dual LP provides a sequence of outer approximations to the global attractor with guaranteed convergence in the sense of volume discrepancy tending to zero. The method is very simple to use and based purely on convex optimization. Numerical examples with the code available online demonstrate the method.

The problem of minimizing an entropy functional subject to linear constraints is a useful example of partially finite convex programming. In the 1990s, Borwein and Lewis provided broad and easy-to-verify conditions that guarantee strong duality for such problems. Their approach is to construct a function in the quasi-relative interior of the relevant infinite-dimensional set, which assures the existence of a point in the core of the relevant finite-dimensional set. We revisit this problem, and provide an alternative proof by directly appealing to the definition of the core, rather than by relying on any properties of the quasi-relative interior. Our approach admits a minor relaxation of the linear independence requirements in Borwein and Lewis' framework, which allows us to work with certain piecewise-defined moment functions precluded by their conditions. We provide such a computed example that illustrates how this relaxation may be used to tame observed Gibbs phenomenon when the underlying data is discontinuous. The relaxation illustrates the understanding we may gain by tackling partially-finite problems from both the finite-dimensional and infinite-dimensional sides. The comparison of these two approaches is informative, as both proofs are constructive.

The various implementations described herein include systems, methods and/or devices used to enable multipass programming in buffers implemented in non-volatile data storage systems (e.g., using one or more flash memory devices). In one aspect, a portion of memory (e.g., a page in a block of a flash memory device) may be programmed many (e.g., 1000) times before an erase is required. Some embodiments include systems, methods and/or devices to integrate Bloom filter functionality in a non-volatile data storage system, where a portion of memory storing one or more bits of a Bloom filter array may be programmed many (e.g., 1000) times before the contents of the portion of memory need to be moved to an unused location in the memory.

Graphical programming or modeling environments in which a coding standard can be applied to graphical programs or models are disclosed. The present invention provides mechanisms for applying the coding standard to graphical programs/models in the graphical programming/modeling environments. The mechanisms may detect violations of the coding standard in the graphical model and report such violations to the users. The mechanisms may automatically correct the graphical model to remove the violations from the graphical model. The mechanisms may also automatically avoid the violations in the simulation and/or code generation of the graphical model.

An application framework including different application programming interfaces (APIs) is described which performs a variety of mobile device functions in response to API calls from applications. For example, in response to relatively simple API calls made by applications the application framework manages the complex tasks associated with invitations and matchmaking. By way of example, the details of complex transactions such as establishing peer-to-peer connections between mobile devices may be transparent to the application developer, thereby simplifying the application design process. The application framework may include an application daemon for communicating with a first set of services and an applications services module for communicating with a separate set of services. The application framework may also include a cache for caching data for each of the services based on different cache management policies driven by each of the services. The cache may be updated by push notification cache updates sent from each of the services.

Techniques are described for utilizing synchronous APIs which normally block callers until a result is returned. In particular, the techniques described herein enable an application or other programming construct to boost performance by executing synchronous APIs (e.g., long running time APIs) within a proxy container rather than executing the synchronous APIs in the context of the application itself. Since the proxy is a separate process or thread, the caller application is thereby released from waiting for the synchronous API call and may proceed with other processing instead of waiting for the synchronous API to return. The application may then monitor the proxy to determine whether a result has been received, such as by periodically polling the proxy.

Methods and systems of monitoring events occurring in a computer system are provided. An event monitoring instruction including a condition is parsed, the event monitoring instruction expressed using syntax defined in source code, the parsing resulting in an event channel to monitor and the condition. Then execution of an application is paused. The event channel is monitored until an event occurs on the event channel. Then an event handler for the event is run in response to the event occurring on the event channel. The condition is evaluated to determine whether the condition is satisfied. Execution of the application is resumed in response to the condition being satisfied.

Methods, systems, and devices are described for communicating physical layer wireless parameters over an application programming interface. A wireless modem of a wireless device may measure at least one physical layer wireless parameter. The wireless modem may report the at least one physical layer wireless parameter to an application running on the wireless device over an application programming interface between the wireless modem and the application. A behavior of the application may be adapted to control wireless communications between the application and a network based on the at least one physical layer wireless parameter reported by the wireless modem. Other aspects, embodiments, and features are also claimed and described.

A system and method allows visual programming of simultaneous and synchronous machining operations on multi-axis lathes. The system and method accounts for different combinations of simultaneous and synchronized lathe operations on the spindles which can utilize multiple tools. A graphic synchronization icon is assigned to each mode that preferably represents the lathe operation. Appropriate synchronous operations are grouped together in synchronization groups. The system and method are universal since a postprocessor processes the synchronization modes and synchronization groups, and translates them for use with computer programs understood by a particular CNC lathe.

In various embodiments, a spectral graph partitioner (“SP”) of a graph partitioning system (“GPS”) may partition a data flow graph associated with a program into a plurality of subgraphs to be used to perform analysis or debugging. The SP may generate estimated eigenvectors for a matrix representing the graph through minimization of a function on the vectors. The SP may generate multiple eigenvectors to perform the clustering in a multi-dimensional space described by the eigenvectors. The SP may refine the clustering by repeating generation of eigenvectors to describe higher-dimensional spaces and perform further clustering. The SP may also determine quality metrics for the clusters and may stop refinement based on the quality metrics. The GPS may select between utilizing the SP or utilizing one or more other partitioners based on various factors such as, for example, graph size or quality metrics. Other embodiments may be described and/or claimed.

Apparatus and methods are disclosed, such as a method that includes precharging channel material of a string of memory cells in an unselected sub-block of a block of memory cells to a precharge voltage during a first portion of a programming operation. A programming voltage can then he applied to a selected memory cell in a selected sub-block of the block of memory cells during a second portion of the programming operation. The selected memory cell is coupled to a same access line as an unselected memory cell in the unselected sub-block. Additional methods and apparatus are disclosed.

A nonvolatile memory device is provided as follows. A memory cell array includes a plurality of memory cells. An address decoder provides a first verify voltage to selected memory cells among the plurality of memory cells in a first program loop and provides a second verify voltage to the selected memory cells in a second program loop. A control logic determines the second program loop as a verify voltage offset point in which the first verify voltage is changed to the second verify voltage based on a result of a verify operation of the first program loop.

I have finally obtained the first batch of the printed "Programming Algorithms" books and will shortly be sending them to the 13 people who asked for a hardcopy.

Here is a short video showing the book "in action":

If you also want to get a copy, here's how you do it:

1. Send the money to my PayPal account: $30 if you want normal shipping or $35 if you want a tracking number. (The details on shipping are below).
2. Shoot me an email to vseloved@gmail.com with your postal address.
3. Once I see the donation, I'll go to the post office and send you the book.
4. Optionaly step: if you want it to be signed, please, indicate it in your letter.

Shipping details: As I said originally, the price of the dead-tree version will be $20+shipping. I'll ship via the Ukrainian national post. You can do the fee calculation online here (book weight is 0.58 kg, size is 23 x 17 x 2 cm): https://calc.ukrposhta.ua/international-calculator. Alas, the interface is only in Ukrainian. According to the examples I've tried, the cost will be approximately $10-15. To make it easier, I've just settled on $10 shipping without a tracking number of $15 if you want a tracking number. Regardless of your country. I don't know how long it will take - probably depends on the location (I'll try to inquire when sending).

The book was already downloaded more than 1170 times (I'm not putting the exact number here as it's constantly growing little by little). I wish I knew how many people have, actually, read it in full or in part. I've also received some error corrections (special thanks goes to Serge Kruk), several small reviews and letters of encouragement. Those were very valuable and I hope to see more :)

Greetings from the far away city of Lima, Peru!
I loved this part: "Only losers don't comment their code, and comments will be used extensively"
Thank you so much for putting this comprehensive collection of highly important data structures, i'm already recommending this to two of my developers, which I hope i'll induce into my Lisp addiction.
--Flavio Egoavil

And here's another one:

Massively impressive book you've written! I've been a Lisp programmer for a long time and truly appreciate the work put in here. Making Lisp accessible for more people in relation to practical algorithms is very hard to do. But you truly made it. You'll definitely end up in the gallery of great and modern Lisp contributions like "Land of Lisp" and "Let Over Lambda". Totally agree with your path to focus on practical algorithmic thinking with Lisp and not messing it up with macros, oop and other advanced concepts.
--Lars Hård

Thanks guys, it's really appreciated!

If you feel the same or you've liked the book in some respect and have found it useful, please, continue to share news about it: that definitely helps attract more readers. And my main goal is to make it as widely read as possible...

Yep, it on!

Let's talk about Blockchain. Goal is to use this forum topic to highlight its usefulness to programming language theory and practice. If you're familiar with existing research efforts, please share them here. In addition, feel free to generate ideas for how Blockchain could improve languages and developer productivity.

As one tasty example: Blockchain helps to formalize thinking about mutual knowledge and common knowledge, and potentially think about sharing intergalactic computing power through vast distributed computing fabrics. If we can design contracts in such a way that maximizes the usage of mutual knowledge while minimizing common knowledge to situations where you have to "prove your collateral", third-party transactions could eliminate a lot of back office burden. But, there might be benefits in other areas of computer science from such research, as well.

Some language researchers, like Mark S. Miller, have always dreamed of Agoric and the Decades-Long Quest for Secure Smart Contracts.

Some may also be aware that verification of smart contracts is an important research area, because of the notorious theft of purse via logic bug in an Ethereum smart contract.

Abstract, references and article information

European countries have ramped up their investments in helping refugees find work and integrate into society. Yet little hard evidence exists of what programs and policies work best. This report proposes a new framework for thinking smartly about integration programming, using cost-benefit analysis to look beyond short-term, economic outcomes to also measure indirect benefits through a social-value concept.

To commemorate the 250th anniversary of the publication of his “Letters From a Pennsylvania Farmer” and the role John Dickinson played in setting the stage for the American Revolution, the Delaware Department of State has launched a new website, de.gov/johndickinson, and a slate of special programming to take place over the coming months.

Pre-eclampsia (PE)-induced fetal programming predisposes offspring to health hazards in adult life. Here, we tested the hypothesis that pre-eclamptic fetal programming elicits sexually dimorphic inflammatory and cardiovascular complications to endotoxemia in adult rat offspring. PE was induced by oral administration of L-NAME (50 mg/kg per day for seven consecutive days) starting from day 14 of conception. Cardiovascular studies were performed in conscious adult male and female offspring preinstrumented with femoral indwelling catheters. Compared with non-PE male counterparts, intravenous administration of lipopolysaccharide (LPS, 5 mg/kg) to PE male offspring caused significantly greater 1) falls in blood pressure, 2) increases in heart rate, 3) rises in arterial dP/dtmax, a correlate of left ventricular contractility, and 4) decreases in time- and frequency-domain indices of heart rate variability (HRV). By contrast, the hypotensive and tachycardic actions of LPS in female offspring were independent of the pre-eclamptic state and no clear changes in HRV or dP/dtmax were noted. Measurement of arterial baroreflex activity by vasoactive method revealed no sex specificity in baroreflex dysfunction induced by LPS. Immunohistochemical studies showed increased protein expression of toll-like receptor 4 in heart as well as in brainstem neuronal pools of the nucleus of solitary tract and rostral ventrolateral medulla in endotoxic PE male, but not female, offspring. Enhanced myocardial, but not neuronal, expression of monocyte chemoattractant protein-1 was also demonstrated in LPS-treated male offspring. Together, pre-eclamptic fetal programming aggravates endotoxic manifestations of hypotension and autonomic dysfunction in male offspring via exacerbating myocardial and neuromedullary inflammatory pathways.

SIGNIFICANCE STATEMENT

Current molecular and neuroanatomical evidence highlights a key role for pre-eclamptic fetal programming in offspring predisposition to health hazards induced by endotoxemia in adult life. Pre-eclampsia accentuates endotoxic manifestations of hypotension, tachycardia, and cardiac autonomic dysfunction in male offspring via exacerbating myocardial and central inflammatory pathways. The absence of such detrimental effects in female littermates suggests sexual dimorphism in the interaction of pre-eclamptic fetal programming with endotoxemia.
