X-force 2017 is a software for cracking autodesk products quickly and accurately does not take much of your time. The user is very easy, I will guide below or in the software, there are video tutorials installed most of the same.

I think I need to chose $n$ less than or equal to $64$, that way I get $1+2+\ldots+63=2016$. If $n$ is odd an greater than $1$ we don't have a solution as it won't go into $2017$. But we need $x$ to be an integer. So I think I've limited the search to $n=2,4,6,\ldots,64$.

So we can just count the number of ways to have an odd number of consecutive integers add up to $2017$: if the center number is $u$ and there are $k$ terms, then obviously the sum is $uk$. So the number of such representations must be just the number of odd factors of $2017$. Since $2017$ is prime, there must be only $2$ such. But the first is just $2017$ itself, so there is only $1008+1009$ left.

The objective of this work is therefore to propose an original solution to the modeling and prediction of the deformation of soft objects that does not make assumptions about the material of the object and that capitalizes on computational intelligence solutions, namely on combining neural gas fitting with feedforward neural network prediction. It builds on a previously proposed solution [7] for capturing the deformed object shape using neural gas fitting. However, the modeling process is improved in this work by an alignment procedure that ensures a simpler interpretation of the deformation (e.g., simpler comparison for various angles and forces) and a similar treatment of the deformation over the surface of an object. In addition, an in-depth analysis conducted on the parameters leads to a more appropriate choice of parameters, that results in a better performance for object representation. Finally, a novel solution is proposed based on a neural network architecture to predict the deformed shape of an object when subjected to an unknown interaction.

(a) Raw data collected; (b) preprocessed data; and (c,d) deformation distributions with respect to the non-deformed object when applying a light and a strong force, respectively; regions in blue are not deformed, and the deformation is getting stronger from green to red.

(a) Aligned model with x, y, z axes, (b) x, y view; and difference between a model when a light force is applied on the top at an angle of 75 with respect to the y axis and the reference model (c) before ICP and (d) after ICP alignment.

In a second stage, a fine alignment is ensured between the reference model, Mr and each simplified and aligned model, Ma_axis, using the iterative closest point (ICP) algorithm [23]. In order to ensure good results, the latter requires that the two models are roughly aligned, from which stems the necessity of the initial axis alignment in the first stage. An example of color-encoded differences obtained using Cloud Compare between the non-deformed object model and a model in which a light force (4 N) is applied on the top at an angle of 75 degrees with respect to the y axis is shown after the axis alignment, but prior to ICP alignment in Figure 4c and after ICP alignment in Figure 4d. One can notice that after the ICP alignment, the differences focus mainly on the deformed zone and not over the entire surface of the ball (e.g., there are more blue areas around the ball surface, showing a better fitting). The combined transformation (translation and rotation) matrix returned by ICP is saved in order to allow the repositioning of the deformed zone at its correct place over the surface of the object.

Additionally, there is a difference between the forces applied on the y axis that is larger than the one over the x axis (i.e., 3 N). This difference is visible in green, red, and yellow around the deformation zone, as expected. For the case in Figure 10b, the force difference is mainly along the y axis and is reflected by differences in the deformation zone, as one might expect. A certain error appears around the sides of the object, as reflected by the green-bluish patches. The last example for the ball is for a force that affects the z and y directions and it is again correctly predicted. Finally, an example is shown for the estimation of the cube for a force varying with 4 N the along y axis. The difference shown in red, yellow, and green is mainly concentrated around this axis as well.

Microsoft Visual C++ Redistributable for Visual Studio 2015-2017 installs run-time components of Visual C++ libraries. These components are required to run C++ applications that are developed using Visual Studio 2015-2017 and link dynamically to Visual C++ libraries. The packages can be used to run such applications on a computer even if it does not have Visual Studio 2015-2017 installed. These packages also install run-time components of C Runtime (CRT), Standard C++, MFC, C++ AMP, and OpenMP libraries.

The evolution of eBPFThe original Berkeley PacketFilter (BPF) [PDF] was designed for capturing and filtering networkpackets that matched specific rules. Filters are implemented as programs tobe run on a register-based virtual machine.The ability to run user-supplied programs inside of the kernel provedto be a useful design decision but other aspects of the original BPFdesign didn't hold up so well. For one, the design of the virtualmachine and its instruction set architecture (ISA) were left behind asmodern processors moved to 64-bit registers and invented newinstructions required for multiprocessor systems, like the atomicexchange-and-add instruction (XADD). BPF's focus on providing a smallnumber of RISC instructions no longer matched the realities of modernprocessors.So, Alexei Starovoitov introduced the extendedBPF (eBPF)design to take advantage ofadvances in modern hardware. The eBPF virtual machine more closelyresembles contemporary processors, allowing eBPF instructions to bemapped more closely to the hardware ISA for improved performance.One of the most notable changes was a move to 64-bit registers and anincrease in the number of registers from two to ten. Since modernarchitectures have far more than two registers, this allows parametersto be passed to functions in eBPF virtual machine registers, just likeon native hardware. Plus, a new BPF_CALL instruction made it possibleto call in-kernel functions cheaply.The ease of mapping eBPF to native instructions lends itself tojust-in-time compilation, yielding improved performance. Theoriginalpatch that added support for eBPF in the 3.15 kernel showed that eBPF was up to four times faster onx86-64 than the old classic BPF (cBPF) implementation for some network filtermicrobenchmarks, and most were 1.5 times faster.Many architectures support the just-in-time (JIT) compiler (x86-64, SPARC,PowerPC, ARM, arm64, MIPS, and s390).Originally, eBPF was only used internally by the kernel and cBPF programswere translated seamlessly under the hood. But with commitdaedfb22451d in 2014, the eBPF virtual machine was exposed directly to user space.What can you do with eBPF?An eBPF program is "attached" to a designated code path in the kernel.When the code path is traversed, any attached eBPF programs areexecuted. Given its origin, eBPF is especially suited to writingnetwork programs and it's possible to write programs that attach to anetwork socket to filter traffic, to classifytraffic, and to run network classifier actions. It's even possible to modify the settings of anestablished network socket with an eBPF program.The XDP project, inparticular, uses eBPF to do high-performance packet processing byrunning eBPF programs at the lowest level of the network stack,immediately after a packet is received.Another type of filtering performed by the kernel is restricting whichsystem calls a process can use. This is done with seccomp BPF.eBPF is also useful for debugging the kernel and carrying outperformance analysis; programs can be attached to tracepoints,kprobes, and perf events. Because eBPF programs can access kernel datastructures, developers can write and test new debugging code withouthaving to recompile the kernel. The implications are obvious for busyengineers debugging issues on live, running systems. It's evenpossible to use eBPF to debug user-space programs by using UserlandStatically Defined Tracepoints.The power of eBPF flows from two advantages: it's fast and it's safe.To fully appreciate it, you need to understand how it works.The eBPF in-kernel verifierThere are inherent security and stability risks with allowing user-spacecode to run inside the kernel. So, a number of checks areperformed on every eBPF program before it is loaded.The first test ensures that the eBPF program terminates and does notcontain any loops that could cause the kernel to lock up.This is checked by doing a depth-first search of the program's controlflow graph (CFG). Unreachable instructions are strictly prohibited;any program that contains unreachable instructions will fail to load.The second stage is more involved and requires the verifier tosimulate the execution of the eBPF program one instruction at a time.The virtual machine state is checked before and after the execution ofevery instruction to ensure that register and stack state are valid.Out of bounds jumps are prohibited, as is accessing out-of-range data.The verifier doesn't need to walk every path in the program, it'ssmart enough to know when the current state of the program is a subsetof one it's already checked. Since all previous paths must be valid(otherwise the program would already have failed to load), the currentpath must also be valid. This allows the verifier to "prune" thecurrent branch and skip its simulation.The verifier also has a "secure mode" that prohibits pointerarithmetic. Secure mode is enabled whenever a user without theCAP_SYS_ADMIN privilege loads an eBPF program. The idea is to makesure that kernel addresses do not leak to unprivileged users and thatpointers cannot be written to memory.If secure mode is not enabled, then pointer arithmetic is allowed but onlyafter additional checks are performed. For example, all pointer accesses are checkedfor type, alignment, and bounds violations.Registers with uninitialized contents (those that have never beenwritten to) cannot be read; doing so cause the program load to fail.The contents of registers R0-R5 are marked as unreadable acrossfunctions calls by storing a special value to catchany reads of an uninitialized register. Similar checks are done forreading variables on the stack and to make sure that no instructions write tothe read-only frame-pointer register.Lastly, the verifier uses the eBPF program type (covered later) torestrict which kernel functions can be called from eBPF programs and whichdata structures can be accessed. Some program types are allowed todirectly access network packet data, for example.The bpf() system callPrograms are loaded using the bpf() systemcall with the BPF_PROG_LOAD command. The prototype of the system call is: int bpf(int cmd, union bpf_attr *attr, unsigned int size);The bpf_attr union allows data to be passed between the kernel anduser space; the exact format depends on the cmd argument. Thesize argument gives the size of the bpf_attr union object in bytes.Commands are available for creating and modifying eBPF maps; maps are thegeneric key/value data structure used for communicating between eBPF programs and the kernel or user space. Additionalcommands allow attaching eBPF programs to a control-group directory or socketfile descriptor, iterating over all maps and programs, and pinning eBPFobjects to files so that they're not destroyed when the process that loadedthem terminates (the latter is used by the tc classifier/action codeso that eBPF programs persist without requiring the loading process tostay alive).The full list of commands can be found in the bpf() manpage.Though there appear to be many different commands, they can bebroken down into three categories: commands for working with eBPFprograms, working with eBPF maps, or commands for working with bothprograms and maps (collectively known as objects).eBPF program typesThe type of program loaded with BPF_PROG_LOAD dictates fourthings:where the program can be attached,which in-kernel helper functions the verifier will allow to be called,whether network packet data can be accessed directly, and the type ofobject passed as the first argument to the program. In fact, theprogram type essentially defines an API.New program types have even been created purely to distinguish betweendifferent lists of allowed callable functions(BPF_PROG_TYPE_CGROUP_SKB versusBPF_PROG_TYPE_SOCKET_FILTER, for example).The current set of eBPF program types supported by the kernel is: BPF_PROG_TYPE_SOCKET_FILTER: a network packet filter BPF_PROG_TYPE_KPROBE: determine whether a kprobe should fire or not BPF_PROG_TYPE_SCHED_CLS: a network traffic-control classifier BPF_PROG_TYPE_SCHED_ACT: a network traffic-control action BPF_PROG_TYPE_TRACEPOINT: determine whether a tracepoint should fire or not BPF_PROG_TYPE_XDP: a network packet filter run from the device-driver receive path BPF_PROG_TYPE_PERF_EVENT: determine whether a perf event handler should fire or not BPF_PROG_TYPE_CGROUP_SKB: a network packet filter for control groups BPF_PROG_TYPE_CGROUP_SOCK: a network packet filter for control groups that is allowed to modify socket options BPF_PROG_TYPE_LWT_*: a network packet filter for lightweight tunnels BPF_PROG_TYPE_SOCK_OPS: a program for setting socket parameters BPF_PROG_TYPE_SK_SKB: a network packet filter for forwarding packets between sockets BPF_PROG_CGROUP_DEVICE: determine if a device operation should be permitted or notAs new program types were added, kernel developers discovered a needto add new data structures too.eBPF data structuresThe main data structure used by eBPF programs is the eBPF map,a generic data structure that allows data to be passed backand forth within the kernel or between the kernel and user space. Asthe name "map" implies, data is stored and retrieved using a key.Maps are created and manipulated using the bpf() system call. When amap is successfully created, a file descriptor associated with thatmap is returned. Maps are normally destroyed by closing theassociated file descriptor.Each map is defined by four values: a type, a maximum number of elements, avalue size in bytes, and a key size in bytes. There are different maptypes and each provides a different behavior and set of tradeoffs: BPF_MAP_TYPE_HASH: a hash table BPF_MAP_TYPE_ARRAY: an array map, optimized for fast lookup speeds, often used for counters BPF_MAP_TYPE_PROG_ARRAY: an array of file descriptors corresponding to eBPF programs; used to implement jump tables and sub-programs to handle specific packet protocols BPF_MAP_TYPE_PERCPU_ARRAY: a per-CPU array, used to implement histograms of latency BPF_MAP_TYPE_PERF_EVENT_ARRAY: stores pointers to struct perf_event, used to read and store perf event counters BPF_MAP_TYPE_CGROUP_ARRAY: stores pointers to control groups BPF_MAP_TYPE_PERCPU_HASH: a per-CPU hash table BPF_MAP_TYPE_LRU_HASH: a hash table that only retains the most recently used items BPF_MAP_TYPE_LRU_PERCPU_HASH: a per-CPU hash table that only retains the most recently used items BPF_MAP_TYPE_LPM_TRIE: a longest-prefix match trie, good for matching IP addresses to a range BPF_MAP_TYPE_STACK_TRACE: stores stack traces BPF_MAP_TYPE_ARRAY_OF_MAPS: a map-in-map data structure BPF_MAP_TYPE_HASH_OF_MAPS: a map-in-map data structure BPF_MAP_TYPE_DEVICE_MAP: for storing and looking up network device references BPF_MAP_TYPE_SOCKET_MAP: stores and looks up sockets and allows socket redirection with BPF helper functionsAll maps can be accessed from eBPF or user-space programs using thebpf_map_lookup_elem() and bpf_map_update_elem() functions. Some map types, such as socket maps,work with additional eBPF helper functions that perform special tasks.How to write an eBPF programHistorically, it was necessary to write eBPF assembly by hand and usethe kernel's bpf_asm assembler to generate BPF bytecode.Fortunately, the LLVM Clang compiler has grown support for an eBPF backend thatcompiles C into bytecode. Object files containing this bytecode canthen be directly loaded with the bpf() system call andBPF_PROG_LOAD command.You can write your own eBPF program in C by compiling with Clangusing the -march=bpf parameter. There are plenty of eBPF programexamples in the kernel's samples/bpf/directory; the majority have a "_kern.c" suffix in their file name.The object file (eBPF bytecode) emitted by Clang needs to beloaded by a program that runs natively on your machine (these samplesusually have "_user.c" in their filename). To make it easier to writeeBPF programs, the kernel provides the libbpf library, which includeshelper functions for loading programs and creating and manipulatingeBPF objects.For example, the high-level flow of an eBPF program and user programusing libbpfmight go something like: Read the eBPF bytecode into a buffer in your user application and pass it to bpf_load_program(). The eBPF program, when run by the kernel, will call bpf_map_lookup_elem() to find an element in a map and store a new value in it. The user application calls bpf_map_lookup_elem() to read out the value stored by the eBPF program in the kernel.However, all of the sample code suffers from one major drawback: youneed to compile your eBPF program from within the kernel source tree.Luckily, the BCC project was created to solve this problem. It includesa complete toolchain for writing eBPF programs and loading themwithout linking against the kernel source tree.BCC is covered in the next article in this series; the full set is: An introduction to the BPF Compiler Collection Some advanced BCC topics User-space tracepoints with BPFComments (20 posted)Mozilla releases tools and data for speech recognition By Jake EdgeDecember 6, 2017 Voice computing has long been a staple of science fiction, but it hasonly relatively recently made its way into fairly common mainstream use.Gadgets like mobile phones and "smart" home assistant devices (e.g. Amazon Echo, Google Home)have brought voice-based user interfaces to the masses. The voiceprocessing for those gadgets relies on various proprietary services "in thecloud", which generally leaves the free-software world out in the cold.There have been FOSS speech-recognition efforts overthe years, but Mozilla's recentannouncement of the release of its voice-recognition code and voicedata set should help further the goal of FOSS voice interfaces.
